Dlaczego Fibre Channel?
Gigabit Bandwidth Now - 1 Gbs today, soon 2 and 4Gbs High Efficiency - FC has very little overhead Multiple Topologies - Point-to-point, Arbitrated loop, Fabric Scalability - from Point-to-Point FC scales to complex Fabrics Longer cable lengths and better connectivity than existing SCSI technologies Fibre Channel is an ISO and ANSI standard

Wysoka przepustowość Storage Area Networks today provide
1.06Gbs today 2.12Gbs this year 4.24Gbs in the future Multiple Channels expand bandwidth i.e.:800 Mbyte/s

Topologie FC Point-to-Point 100MByte/s per connection
Just defines connection between storage system and host

Topologie FC, dc. FC-AL, Arbitrated Loop Single Loop Dual Loop
Data flows around the loop, passed from one device to another Dual Loop Some data flows through one loop while other data flows through the second loop Each port arbitrates for access to the loop Ports that lose the arbitration act as repeaters

Topologie FC, cd. FC-AL, Arbitrated Loop with Hubs
Hubs make a loop look like a series of point to point connections. 2 3 1 HUB 4 Addition and deletion of nodes is simple and non-disruptive to information flow.

Topologie FC, cd. FC-Switches 1 2 3 4
Switches permit multiple devices to communicate at 100 MB/s, thereby multiplying bandwidth. 2 1 SWITCH 3 4 Fabrics are composed of one or more switches. They enable Fibre Channel networks to grow in size.

So how do these choices impact my MPI application performance ?
Let‘s find it out by running ... Micro Benchmarks to measure basic network parameters like latency and bandwidth Netperf PALLAS MPI-1 Benchmark Real MPI Applications ESI PAM-Crash ESI PAM-Flow DWD / RAPS Local Model

Benchmark HW Setup 2 Nodes HP N4600 each with 8 processors running HP-UX 11i Lots of NW Interfaces per node 4 * 100BT Ethernet 4 * Gigabit Ethernet Copper 1 * Gigabit Ethernet Fibre 1 * HyperFabric 1 Point-to-point connections, no switches involved J6000 benchmarks were run on a 16 node cluster at the HP Les Ulis benchmark center (100BT and HyperFabric 1 switched networks) HyperFabric 2 benchmarks were run on the L3000 cluster at the HP Richardson benchmark center.

Jumbo Frame Same Performance with Fibre and Copper GigaBit ?
GigaBit Ethernet allows the packet size (aka Maximal Transfer Unit MTU) to be increased from 1500 Bytes to 9000 Bytes. Can be done anytime by invoking lanadmin –M 9000 <nid> Can be applied to both Copper and Fibre GigaBit interfaces.

GigaBit MTU Size / Fibre vs Copper

What is the Hyper Messaging Protocol (HMP) ?
Standard MPI Messaging with remote nodes goes through the TCP/IP stack. Massive Parallelism with clusters is limited by OS overhead for TCP/IP. Example: PAM-Crash MPP on a HP J6000 HyperFabric workstation cluster (BMW data set) 25% System Usage / CPU on a 8x2 cluster 45% System Usage / CPU on a 16x2 cluster This overhead is OS related and has nothing to do with NW interface performance.

What is HMP ? HMP Idea: Create a shortcut path for MPI applications in order to bypass some of the TCP/IP overhead of the OS Approach: Move the device driver from OS kernel into the application. This requires direct HW access privileges. Now available with HP MPI 1.7.1 Only for HyperFabric HW

MPI benchmarking with the PALLAS MPI-1 benchmark (PMB)
PMB is an easy-to-use MPI benchmark for measuring key parameters like latency and bandwidth Can be downloaded from Only 1 PMB process per node was used to make sure that NW traffic is not mixed with SMP traffic. Unlike the netperf test this is not a throughput scenario.

Selected PMB Operations

In simplified terms, the “crossbar” provides literally two (2) switches in the xp1024 (two for redundancy) that enable all data paths to remain open without any contention. This translates to an aggregation of backplane throughput of 15 GB/s. The XP architecture is highly redundant with no single point-of-failure. Redundant components and online firmware upgrades keep the array up and running, and ensure that critical data is available for use. This architecture is also highly efficient. The host side (CHIP) processes cache hits, checks access rights, and links protocols, so server requests are processed and handled quickly. Channel Host Interface Process (CHIP) is a PCB used for data transfer control between the host and cache memory. Array Control Process (ACP) is a PCB used for data transfer control between disk drives and cache memory. Four ports per PCB are mounted. Ports are controlled by their respective dedicated microprocessors and data is transferred concurrently between ports and disk drive. Cache memory is nonvolatile memory (battery backed up) and write data is duplicated so that data loss is not caused even when a failure of one component occurs in power supply or PCB. Shared memory is nonvolatile memory (battery backed up) used to store cache directories and disk control information. The required shared memory varies with the size of cache and number of LDEVs. cache and shared memory 128 GB

XP Next Gen RAID types RAID 1 2D+2D RAID 1 4D+4D RAID 5 3D+1P RAID 5
2nd RAID 1 2D+2D RAID 1 4D+4D RAID 5 3D+1P RAID 5 7D+1P RAID 5 6D+2P Data Data Data Data Data RAID 1 2 data + 2 mirrored data configuration. The array can read from either set of identical information. RAID 0/1 results in 50% efficiency of usable storage compared to raw capacity. RAID 1 4 data + 4 mirrored data, doubles the maximum size of a RAID 1. For certain operating systems, having a smaller number of larger capacity stripes makes configuring the storage easier and simpler. RAID 5 3 data + 1 parity drive configuration. This results in 75% efficiency of raw storage. RAID 5 7 data + 1 parity configuration. This configuration improves the storage efficiency to 87.5% of usable compared to raw storage. RAID 5 6 data + 2 parity configuration. This configuration improves the fault tolerance. Two drives from one group can fail and data is still available. Trade-off is slightly lower write performance. This RAID type can also properly be called RAID 6. Scheduled to be available for 2nd release. All RAID types can be configured in the same XP array at the same time. RAID level 1 is a combination of RAID levels 0 and 1. The array is first set up as a group of mirrored pairs (RAID 1), then striped (RAID 0). A RAID level 0/1 array done in this manner can sustain multiple drive failures, as long as both drives of a mirrored pair do not fail at the same time. The probability of this occurring is very low. Performance is very good with RAID 0/1 arrays, and redundancy is also very high, but it comes at the cost of additional disk drives. RAID 5 uses block level striping and distributed parity. RAID 5 distributes the parity over all of the drives to increase performance by decreasing the bottleneck to a single drive. RAID 5 parity is used for fault tolerance. Write Performance RAID 1 writes require 2 I/Os (the same data written twice)—RAID 1 is the fastest write performing RAID type. RAID 5 (3D+1P) and RAID 5 (7D+1) writes require 4 I/Os (1-read old data, 2-read old parity, 3-write new data, 4-write new parity)—RAID 5 write performance can be as low as one half the performance of RAID 1 writes. RAID 5 (6D+2P) writes require 6 I/Os (1-read old data, 2-read old parity , 3-read old parity, 4-write new data, 5-write new parity, 6-write new parity)—RAID 5 (6D+2P) write performance can be as low as one third the performance of RAID 1 writes. Read Performance The read performance of all RAID types is similar. The XP disk arrays automatically use a spare drive when a disk failure occurs, making the time of degraded protection small. After the failed drive is replaced the data is rebuilt and the spare drive is free.

Online firmware update
Online firmware update without any host ports going down Each CHIP has multiple processor modules. Each processor module contains a pair of microprocessors One microprocessor of a pair is updated, while the other microprocessor in the pair continues to service the host ports for the pair with little impact to performance Enables remote firmware update capability independent of host connection topology Firmware executes on microprocessors on CHIPs and ACPs (SVP and environmental functions also have some firmware). A CHIP has multiple processor modules. Each module has 2 microprocessors. The requirement for online update is that one microprocessor on a module gets updated while the other microprocessor continues to operate the host ports being served by both microprocessors. Because of the options that exist for how the firmware gets updated, the actual updates may occur from between 1 microprocessor in a cluster at a time (which would be one microprocessor on one CHIP) to half of the microprocessors in the entire cluster at a time (which is half of the microprocessors on all the CHIPs in one cluster). Online firmware update works with every connection configuration instead of requiring redundant connections. Therefore, firmware updates can be done remotely without a visual inspection of the machine. XP Next Gen enables a simpler online firmware update capability by eliminating the need for redundant host paths in the SAN or direct FC connections to hosts. This makes it possible to provide firmware updates remotely without complicated site qualification audits. Microcode update usually requires 5-10 minutes of time to complete. Host Port Micro processor Host Port Micro processor Host Port Micro processor Host Port Micro processor Before Update 1st Processor Update 2nd Processor Update After Update

Battery Internal environmentally friendly nickel-hydride batteries allow the XP Next Gen to continue full operation for up to one minute when the AC power is lost. During this minute all the disk drives continue to operate normally. When duration of the power loss is longer than one minute, the XP Next Gen executes either the De-stage Mode or Backup Mode, protecting data for up to 48 hours. The choice of De-stage vs. Backup mode has dependencies. If the array has 2 ACP pairs or less and no external storage, either mode can be chosen. If external storage is connected or there are 3 or more ACP pairs, then Back-up mode must be used. The Auto-Power-On switch choices of behavior are: automatic restart or manual intervention restart for sites that want to be sure the power has become stable before restarting operations. Using an external “uninterruptible power supply” (UPS) can continue operation for as long as the UPS can supply power.

High-speed, real-time data replication
Business Copy XP Features real-time local data mirroring within XP disk arrays full copies or space-efficient snapshots enables a wide range of data protection data recovery and application replication solutions instant access/restore flexible host agent for solution integration Benefits powerful leverage of critical business data for secondary tasks allows multiple mission-critical storage activities simultaneously High-speed, real-time data replication HP StorageWorks Business Copy XP is a local mirroring product that maintains one or several copies of critical data through a split-mirror process. Asynchronous copy volume updates ensure primary application performance is not adversely affected. With XP Next Gen, space efficient snapshot local copy will be available in addition to the existing full-copy/clone capability. Problem Several workloads or processes may require the same set of data across multiple applications. However, in order to run one application, the “competing” application cannot be run and is therefore unavailable. A simple example of this is the backup of a database. To ensure a coherent database backup, all online transactions need to be halted. The database is therefore unavailable during this backup process. Solution HP Business Copy XP provides a solution by supporting multiple copies of the production data. (Up to nine full-copy or 32 snapshot/space-efficient concurrent copies). Each copy of the data can be used for various purposes—backup, new application testing, or data warehousing loading—without any disruption to the primary application and primary data, and most importantly, all without any disruption to your business operations. At the same time, you will be creating faster implementation of new requirements and capabilities so that your business will succeed. Additional note May be used in conjunction with Continuous Access XP to maintain multiple copies of critical data at local and remote sites. Note: Continuous Access XP is only supported with Data Protector on HP-UX servers. Both HP Data Protector and VERITAS NetBackup products have been tightly integrated with HP Business Copy XP to provide Zero Downtime and Split-Mirror Backup solutions for the HP Surestore XP disk arrays on multiple server platforms.

Business Copy XP Full copy vs. Snapshot
There are pros/cons to using either Full copy or Snapshot: Full-Copy Because an independent copy is made when a clone is created, any activity against that copy do not affect the primary data from which it was created. And in comparison to Snapshots, where a copy-on-write operation must be completed before primary/snapshot-common data can be overwritten, Write activity against cloned primary data is accomplished unencumbered by local mirroring activities. Clones are storage intensive – an equal amount of storage capacity must be provisioned for each primary data source copied. Clones are most useful when performance concerns are paramount (when unfettered access to primary or mirror image data must be insured) or when a completely independent local copy image is required (e.g. for recovery from disk implementations). Snapshot/Space-efficient Because only differential data must be additionally committed to disk, Snapshots can be very storage capacity efficient. For primary or mirror data that is not updated very frequently or very much, incremental capacity consumption can be very low. Due to the logical/metadata nature of snapshots, many more concurrent copies can be created and managed. A Read operation of a Snapshot image can impact I/O operations to the primary dataset if the read data resides on the primary volume – and potentially contend with whatever operations that are continuing on that volume. A Write operation of a Snapshot image can also impact I/O operations to the primary dataset if the data to be written resides on the primary volume. That data must be copied over to the snapshot pool so as to preserve the data integrity of the primary volume. A Write operation of a Primary image can be impacted if Snapshots of that image are being maintained. Any data that is required to maintain integrity of a snapshot image must be copied over to the snapshot pool before the write operation can be performance so as to preserve the data integrity of the primary volume. Snapshots are most useful when cost/performance issues are paramount. They are even more practical/appropriate for low I/O activity environments, where Snapshot maintenance does not unduly impact primary data I/O operations.

ESCON is primarily used to connect with older XP256 XP disk arrays that don’t support Fibre Channel Continuous Access HP StorageWorks Continuous Access XP Multi-site is a remote replication tool that is the basis of 1:2, and 1:1:1 multi-site replication solutions. Using it’s unique Journal-based replication technology, it enables a single volume to replicated to two distinct arrays or a single volume to be cascaded to two distinct arrays (see other slide). Journal-based replication results in better remote link bandwidth utilization. Replication operations consume less bandwidth and therefore allow for relatively lower bandwidth link capacity to be deployed for such a solution.

If the timer pops, the link is suspended until operator intervention (pairresync command). Converters like CNT do automatic re-transmission which should help. XP disk array behavior must be overlaid with expected FC driver and LVM behavior so that proper Threshold and timeouts are purposefully chosen. For example, if the FC driver receives a response within 10 seconds, all is OK. If not, it waits 2 seconds and retries. LVM watches all this with a 60 second timeout. If I/O completes in that time (up to 5 FC driver retries), all is OK. If not, the port is considered down and LVM switches to a pvlink. While the link is suspended, both sides start using a bit map (#4 in RCU goes into a bit map, all new and unsent sidefile writes go into an MCU bitmap.

Continuous Access XP Journal vs. Continuous Access XP Extension
Remote Copy Primary 1 4 Primary 1 Remote JNL HP StorageWorks Continuous Access XP Journal can be compared and contrasted with traditional Continuous Access XP Extension (asynchronous) operation: CA XP Journal architecture is uniquely suited for one-to-many or one-to-one-to-one configurations. CA XP Async can only facilitate one-to-one configurations. With CA XP Journal, update data (in the form of the journal) is stored on traditional disk, while CA XP Async queues change data in array cache. This means that CA XP MS can be more tolerant of high or fluctuating workload environments where tracking/recording or update data can ‘fall behind’ primary data operations. Much more capacity in the form of disk can be provisioned to store such data with CA XP Journal and, thus, forms a more resilient ‘buffer’ for remote copy operations. With CA XP Journal, the journaled data consists of track-level change information. When the remote site journal ‘reads’ changes on the primary site journal, multiple track-level changes can be aggregated and retrieved . With CA XP Extension (Async) , transaction must be replicated across the remote link on an I/O by I/O basis. Depending on the application/database environment, such an ‘atomic’-level replication scheme can be very inefficient.

Furthermore, these solutions result in compromised mirror data currency on the Contingency Site as replication to that site does not occur on a real time basis with respect the Primary Site. In a traditional cascaded configuration, a synchronous copy image is created on the Hot Standby Site array using Continuous Access XP. From that copy image, a local copy is paired/created on the Hot Standby Site array using Business Copy XP. On a ongoing basis, the local Business Copy image does not represent a logically consistent image of its parent volume. In order to obtain such a consistent image, the local copy image must be ‘split’ from the parent image, creating a point-in-time image of the parent. That local copy image can then be copied asynchronously to the Contingency Site XP array using Continuous Access XP Extension (Async.) Because the Hot Standby Site local copy represents a point-in-time image, the Contingency Site remote copy image can, at best, only be current with this image. In the meantime, the Hot Standby Site local copy falls behind the Primary Site/Volume, with data currency of the Contingency Site remote mirror being compromised. This operation is highly coordinative in nature, with the local image on the Hot Standby Site having to be continuously split and resynched with it’s parent volume.

This module eliminates the need for the customer to maintain their own binder with printed reports that they have to manually update. Command View updates the configuration automatically eliminating this tedious task. Path Connectivity also provides diagnostic capabilities for the fibre channel connection between hosts and the XP. This feature will identify if a particular connection has begun to degrade and then provide diagnostic information to speed up the troubleshooting process by identifying potential causes. Command View XP runs on a Windows 2000 or Windows 2003 management station.

LUN Configuration & Security Manager XP
Features assignment of LUNs via drag ‘n drop assignment of multiple LUNs with single click checks each I/O for valid security LUN and WWN group control Benefits flexibility to configure the array to meet changing capacity needs permissions for data access can be changed with no downtime every I/O is checked to ensure and maintain secure data access Easy-to-use menus for defining array groups, creating logical volumes and configuring ports HP StorageWorks LUN Configuration Manager and Security Manager XP is a new combination product combines a configuration and capacity expansion tuning tool together with the best security available. LUN Configuration Manager contains three applications in a single easy-to-use tool that launches directly from the HP Command View XP user interface. LUN Management lets you add or delete paths, set the host mode, set and reset the command device, and configure Fibre Channel ports. LU Size Expansion (LUSE) lets you create volumes that are larger than standard volumes. Volume Size Configuration (VSC) allows configuration of custom size volumes that are smaller than normal volumes—improving data access. Security Manager is your LUN security watchdog that gives you continuous, real-time, I/O-level data access control of your XP array. It allows you to restrict the availability of a single LUN or group of LUNs to a specified host or group of hosts. Secured LUNs become inaccessible to any other hosts connected to the array. Unauthorized hosts no longer have access to data that is off-limits. HP LUN Configuration Manager XP allows a system administrator to set up and configure LUNs and assign them to ports. Additionally there are two programs that allow LUNs to be created which are smaller and larger than the available open emulation types. For example, many smaller LUNs can be combined to form a single large LUN using LUN size expansion (LUSE), which is important in environments where there are restrictions on the total number of LUNs supported. Custom-size volumes are smaller than the standard emulation types and can be easily created using Open Systems Custom Volume Size (OCVS). This is important when LUNs may need to be downsized in capacity to avoid wasting disk space. A good example here is when there is a need to create a command device for an XP application. This sample screen shot shows part of the process involving LUN setup and shows a table mapping SCSI ID, and LUN number, volume and emulation type. HP Surestore Secure Manager XP restricts access to LUNs or groups of LUNs to a specific host or group of hosts by checking every I/O. Permissions to access data can be changed on-the-fly with no downtime. Create LUN groups and WWN groups to simplify the configuration and management of data. Integrated into HP Command View and accessible from the same management station. Security is enabled at the port level for flexible deployment with all host server environments supported by the XP disk array family. New drag and drop capability integrated into CommandView. NOTE: HDS/SUN will have similar capability. We expect them to expose this functionality through HDS’s HighCommand device manager. Note: XP128/1024 LUN Configuration & Secure Manager functionality is bundled together as a single product. For legacy systems, LUN Configuration Manager and Secure Manager XP are used by customers. Both products provide the same functionality level; however, it is bundled slightly differently for the XP128/1024. Under volume management, customers can group LUNs – even if they are not concatenated providing more flexibility as customers do not need a free list of LUNs – they can just pick and choose available LUNs.

Performance Advisor XP
Features real-time data gathering and analysis system view of all resources flexible event notification and large historical repository Benefits identify performance bottlenecks before they impact business helps maintain maximum array performance precise integration eliminates “blame storming” across systems, database and storage administrators Collect, monitor, and display real-time performance HP StorageWorks Performance Advisor XP is a web-based application providing real-time collection and monitoring of your XP disk arrays. HP Performance Advisor XP collects data on CHIP & ACP utilization, and sequential and random reads/writes and I/O rates at each LDEV. No need to worry that your XP resources are not performing XP resources are not performing up to expectations. Its performance alarm and notification capabilities will keep you ahead of any problems. Collects data on a real-time basis, making it easy to see up-to-date and current performance patterns. (Some competing products collect data only on a sporadic basis, several times a day, making their data stale and dated.) Can be accessed by a tab on the Command View (CV) screen. By clicking the Performance Advisor tab, you automatically click the PA URL and start the PA application, saving administrator time and effort. Alternatively, Performance Advisor XP can run as a completely standalone application with its own GUI. Performance Advisor is installed on a PC-based management station (it can be on the same station that CV is installed on), and multiple arrays and multiple hosts can be examined from the same station. Select one array and look at all the hosts attached to it. Or select one host and look at all the array components. This makes it easy to see which hosts are imposing the heaviest workload on the XP disk array. Alert thresholds can be set to send alarms when the threshold has been reached to warn you that attention may be needed or workloads are approaching a critical stage where you may need to take some action to head off a rash of user complaints. VantagePoint Operations (OpenView performance monitor) can access the same performance data that is collected by Performance Advisor. Precise (a third-party Oracle performance optimization tool) can access the same data generated by Performance Advisor and solve database processing bottlenecks. Data from up to 8000 LUNs can be displayed very quickly in one PA window. It takes only two minutes to display this large amount of data, even though it is unlikely you would want to view that many LUNs at one time. Up to 2 GB of historical performance data can be stored making it easy to analyze trends (a leading competitor stores only 500 MB). Additional notes: Flexibility to view “many-to-many” hosts, arrays, LUNs, or components works with Windows 2000/NT, HP-UX, SUN, IBM AIX, Linux, (mainframes soon) Event notification by to pager or PC or VPO console Web-based integration with HP Command View XP

Boost performance by redirecting I/O requests to the cache
Cache LUN XP Features stores critical data in the XP array cache user configurable, easy to use fast file access and data transfer scalable Benefits speeds access to mission critical data provides access to critical data such as database indices in nanoseconds rather than milliseconds Boost performance by redirecting I/O requests to the cache HP StorageWorks Cache LUN XP lets you reserve areas of cache memory on your HP StorageWorks XP disk array to store frequently accessed information. You’ll see improved file access times and faster data transfers. Cache-resident data is accessed in nanoseconds instead of milliseconds for both read and write I/O operations. HP Cache LUN redirects I/O requests from the XP array disk drives to the XP array cache memory to boost performance for frequently accessed data. Simple to implement with HP Command View XP integration, and transparent to the array operation, performance gains are immediate. You can cache up to 1024 volumes for the ultimate in efficiency. HP Cache LUN is the answer for LUNs that are heavily accessed like index files or database logs. When you want to use the cache for something else, destage the data back to its original location. Once the “hot” data is cache resident, it is accessed in nanoseconds rather than in milliseconds. Performance improvements occur immediately. Increase cache memory before running HP Cache LUN XP to avoid degradation when accessing non-cached data.

Performance Control XP
Features Control consumption of array performance by IO/s or MB/s Precise array port level settings reports and online graphing Benefits allows customer to align business priorities with the availability of array resources Effectively manage mission-critical and secondary applications more efficient use of array bandwidth allows for performance-level service-level oriented deployment Allocates performance bandwidth to specific servers or applications HP StorageWorks Performance Control XP lets you allocate XP disk array performance resources to hosts, so you can align those resources with computing priorities, maximize storage ROI, and deploy XP disk arrays in service-provider solutions. PCXP is Web-based software that plugs into Command View XP and allocates XP array performance bandwidth to specific servers or applications, based on user-defined policies What problems does it solve? Lack of complete systems performance management solutions and flexible interfaces Lack of tools that provide granular control of resources or groups of resources which have an impact on overall performance Keeping things simple yet powerful enough to really have an overall effect on performance Customer benefits Entire configuration is better understood, relationships are clear, and policy decisions are more accurate and are arrived at more quickly Applications automatically get the bandwidth they need, when they need it Simplified performance management and reporting Information is secure Performance policies can be assigned by HBA, WWN or user assigned-nicknames Schedule by hour or by day

Non-disruptive volume migration for performance optimization
Auto LUN XP Features optimizes storage resources moves high-priority data to underutilized volumes identifies volumes stressed under high I/O workload creates a volume migration plan migrates data across different disks or RAID levels Benefits improves array performance and reduces management costs by automatically placing data in highest performing storage (cache, RAID 1, RAID 5) Non-disruptive volume migration for performance optimization HP StorageWorks Auto LUN XP provides automatic monitoring and load balancing of your HP StorageWorks resources. HP Auto LUN XP compares disk array LUN utilization to limits set by you. It even proposes a data and volume migration plan so that hot spots and other potential disk bottlenecks are avoided, providing optimal, load-balanced performance. HP Auto LUN XP analyzes the current array operation and uses its knowledge about the data layout on the array to suggest how best to relocate data on the XP disk array to improve performance. The administrator then has the option to say “yes” or “no” before any data is moved according to the plan generated by Auto LUN. It works in several discrete phases, reports on its findings, generates an action plan, but doesn’t move anything on the array until you give it your command. Benefits include: Keeps highly accessed data on higher performance disk drive groups. Migrates across different disks or RAID levels for better performance. Shorter random I/Os (2k-4k) may be better suited for storage on smaller, faster disk spindles. Under certain circumstances, RAID 1 may be faster than RAID 5, etc. Simple, easy-to-use operation: Easy-to-follow menus Up to 90 days of history are stored and usable reports are generated. Data can be exported to Excel for further graphing and charting. Moving volumes is easy as the data is copied on the source volume to the target volume. Then, host access is transferred to the target volume to complete the migration. At first release 4096 pairs are supported At second release 8191 pairs are supported High Capacity Disks 73 GB Policy-based LUN Migration 36GB High Performance Disks

Secure Path XP Auto Path XP

Host-based software that provides automatic protection against HBA path failures between the server and storage. What problems does it solve? Complete protection of all HBA and I/O data paths, no single point of failure Lack of heterogeneous HBA and I/O protection solutions Full integration with vendor’s management software and third party software Load balancing after a failure Customer benefits No administrator intervention in the event of a failure; training is simplified Full integration with HP XP management software; simplifies training and support, common interface Heterogeneous support for HP-UX, Windows NT/2000, IBM AIX and Linux Performance is maintained despite an I/O path failure HP-developed Auto Path XP products are available for Windows NT/2000 and HP-UX. We are currently working on HP Auto Path XP for Linux and for HP-UX for future releases. The HP-developed products will work with the XP disk arrays as well as the VA family of arrays, thus providing flexibility for SANs that incorporate both products. In addition, we sell an HDS-developed Auto Path XP product for AIX. This one works only with the XP disk arrays. Note: We also have an NT product from Hitachi, which was placed on blind CPL in June to encourage orders on the HP-developed NT product. This product also supports SCSI failover. Sun Solaris support is provided only on a business need basis through the NSSO big deal escalation process. To date, Windows NT and 2000 have supported a limited "SCSI Reservation Protocol" that is not fully optimized for Clustered Servers using Fibre Channel Storage. The SCSI Reservation Protocol must be "re-distributed" every time an I/O attempt is not properly executed causing performance problems, specifically with I/O path load-balancing. HP is modifying the XP firmware and HP's I/O Path failover software, HP Auto Path XP, to support the "Persistent Reservation Protocol." Persistent Reservations support is built into the XP128 and XP1024 firmware and will be built into all HP Auto Path XP software, allowing HP's I/O path failover solution to support "dynamic load balancing" in MSCS Windows NT and 2000 environments as well as Serviceguard for HP-UX and Serviceguard for Linux environments. HP is the 1st in the industry to have this capability.
