2 Corporate Headquarters Hewlett-Packard 3000 Hanover Street Palo Alto, CA , U.S.A. Tel: Fax: Internet: Overview The Enterprise Virtual Array (EVA) Series is part of HP s StorageWorks family of RAID disk arrays. These modular storage solutions are available in two models the EVA3000 and the EVA5000 and are designed for open systems environments and compete in the midrange enterprise market. Also included in the HP StorageWorks product line are: StorageWorks XP Series HP s high-end disk array product, the StorageWorks XP Series is composed of enterprise storage systems designed for use in large heterogeneous data centers (that is, where two or more operating systems are accessing the SAN fabric). Products in the XP Series are the only ones in the StorageWorks disk array line that support both mainframe and open systems environments. StorageWorks Modular SAN Array 1000 (MSA1000) The newest member of the StorageWorks family, the MSA 1000, is a 2Gb Fibre Channel storage system that will be HP s lead product in the entry-level market. StorageWorks Virtual Array 7100/7400/7410 Series Also designed for the midrange, the Virtual Array (VA) Series products use virtual array technology to improve management and administration. All three models are open systems disk arrays and can be used in heterogeneous environments. These products are still being marketed by HP; however, they are no longer the company s lead products in their respective markets. The MSA1000 has eclipsed the VA products at the entry-level, while the Enterprise Virtual Array has become the lead product in the midrange. Products that are still available from HP, though no longer actively marketed, include: StorageWorks Modular Array Series This series is made up of three products the Modular Array 8000 (MA8000), Enterprise Modular Array (EMA12000) and the Enterprise Modular Array (EMA16000) all using a modular architecture where the controller shelves are sold separately from the drive shelves. The StorageWorks EMA/MA products are covered in a separate report. HP now leads with its EVA products in the midrange enterprise space. RAID Array 3000 The low-end model in the StorageWorks line, the RA3000 uses a traditional design where the storage controller and the disk drive bays are all in the same unit. While it is still available, the RA3000 is no longer actively marketed and will be phased out by mid-year This report covers the StorageWorks EVA products only. 16 July

3 HP StorageWorks EVA The EVAs are open systems, 2Gb Fibre Channel, modular disk arrays. The first model, previously known simply as the EVA, now goes by the name of EVA5000. It is being targeted at the upper end of the midrange enterprise market for use where storage consolidation on heterogeneous SANs is important. The second model, introduced in April 2003, is called the EVA3000. It is a lower-capacity model targeted at the midrange enterprise market, where it will take the place of HP s EMA/MA series and VA 7410 as HP s lead midrange product going forward. The modular components of the EVAs install into fully pre-wired 41U- or 42U-cabinets (though the 42U rack is expected to be phased out soon). The controller assembly modules, which have two disk controllers in them, and the 14-bay 2Gb Fibre Channel disk enclosures (model numbers 5214 and 5114), are both 3U high. For the EVA5000 with more than four disk enclosures, there are also two standard embedded loop switch modules that are each 1U high. The EVA3000 can be configured along with HP ProLiant servers in a rack. The EVA5000 uses its own dedicated rack. EVA3000 The newest member of the EVA family is the EVA3000. It supports up to 28 disk drives (4.1TB) in its base configuration (controller unit plus two 14-bay disk enclosures) and can be scaled up to 56 drives (8.2TB) with the addition of two disk enclosures. The EVA3000 comes standard with two controllers operating in dual active redundant mode, each with 1GB of controller cache for a total of 2GB of cache per EVA3000 system. The EV3000 ships with version 2.0 of HP s Virtual Controller Software (VCS), which is described in more detail in the Analysis section of this report. EVA5000 The EVA5000 comes with a customer s choice of four base unit models, with varying levels of scalability. The largest, the EVA5000 2C12D, supports up to 168 drives (24.5TB) in a fully configured cabinet one controller module plus twelve 14-bay disk enclosures. Scalability is increased to 35TB by adding an expansion cabinet that houses 72 additional drives for a total of 240 drives. This is achieved by adding six more 14-bay disk enclosures. Mathematically, that brings the drive bay total up to 252, but the EVA5000 s controller pair only supports a maximum of 240 drives. HP s smallest EVA5000 base unit model is called the 2C2D-B. It supports a maximum of 28 drives (4.1TB) using a controller unit and two 14-bay disk enclosures. In between, HP offers an EVA5000 2C6D- B model, which supports up to 84 disk drives (12.3TB) using a controller unit and six disk enclosures. Both of these models can be scaled up to 240 drives (35TB) by first adding enough disk enclosures to reach 12 in the base cabinet, and then adding an expansion cabinet with six more drive enclosures. A 12- drive enclosure expansion cabinet is also occasionally used with two 2C12D base units to achieve a 480 drive, 70TB, four-controller configuration. Finally, the EVA5000 is also available in a pre-configured technical computing model called the EVA5000 8C8D. The 8C8D model features eight controllers and up to 112 disk drives (in eight M5214 disk enclosures) for a total raw capacity of 16.4TB. Along with the name change in May 2003, HP announced that the EVA5000 was upgradable to a new version of VCS firmware (v3.0), which provides supports for HP s remote replication product (HP StorageWorks Continuous Access EVA), something that was missing on the previous EVA. Customers with existing EVA systems who wish to upgrade from VCS version 2.0a to the new version 3.0 can do so. HSV110 and HSV100 RAID Controllers 16 July

4 The EVA5000 uses HP s HSV110 disk controllers with PowerPC microprocessors. Each EVA5000 control module comes with two HSV110 disk controllers in an active/active configuration. Each controller pair can support up to 240 Fibre Channel drives through two 2Gb backend Fibre Channel loops per controller, even though only 168 physically fit in a single 41U or 42U cabinet. HP recommends that customers use an even number of drive enclosures to reach their desired capacity and that those enclosures be split evenly between the two controllers (that is, 18 enclosures to reach the 240 drive maximum, rather than 17 enclosures with 238 drives). The backend FC loop switches are required when the EVA5000 is configured with more than four drive enclosures. Each HSV110 controller has two Fibre Channel front-end ports for a total of four 2Gb-ready Fibre Channel interfaces to the host per system. In a full 2Gb Fibre Channel path configuration, the aggregate data transfer rate per controller therefore scales up to 8Gb. There is also an additional 2Gb Fibre Channel connection between the two controllers, which is dedicated to the cache mirroring function. This allows the cache mirroring to be turned off at the individual virtual disk (LUN) level if the application needs be optimized to achieve maximum sequential Read/Write data throughput (MB/second transfer data rate). Each HSV110 controller supports 1GB of cache for a total of 2GB cache per system. The EVA3000 utilizes HP s HSV100 disk controller, also with PowerPC microprocessors (the same ones as on the EVA5000). Each EVA3000 control module ships with two HSV100 disk controllers in an active/active configuration, with each controller pair supporting up to 56 drives. Each HSV100 controller has two Fibre Channel front-end ports for a total of four 2Gb Fibre Channel interfaces to the host per system. The number of 2Gb backend Fibre Channel loops per HSV100 controller pair is two, compared to four on the EVA5000. Therefore, in a full 2Gb Fibre Channel path configuration, the EVA3000 s aggregate data transfer rate per controller scales up to 4Gb. As with the EVA5000, the HSV100 also supports an additional 2Gb Fibre Channel connection between the two controllers, which is dedicated to the cache mirroring function. There are no back-end Fibre Channel loop switches on the EVA3000, since the maximum number of drive enclosures is four. Each HSV100 controller supports 1GB of cache for a total of 2GB cache per system. Virtualization The primary distinguishing feature of the EVA Series is its ability to do storage system-level virtualization via mapping of data blocks within the individual application LUNs across a pool of physical disks. Virtualization eliminates the physical boundaries of traditional architectures and forms all disks into one or more virtual pools. The HP EVA can then allocate or reallocate dynamically between hosts and application LUNs of any virtualized RAID set type, assuming the operating system and application do not require operator intervention. As with most systems, this applies to the nondisruptive creation and expansion of LUNs, but not to the shrinking of LUNs. This virtualization capability comes standard as part of the base EVA products. The EVAs support up to 16 virtual storage pools behind a controller pair. Each storage pool can be made available to any and all connected hosts (including multivendor hosts). When new capacity is added to the virtual pool and underlying hidden virtualized RAID sets, the EVAs on the fly leveling algorithm incorporates the new capacity automatically and rebalances the workloads with minimal disruption. This self-tuning application comes as part of the virtualization capability that is standard on the base configuration EVAs. The virtualization pool is centrally managed via a centralized software component called CommandView EVA using HP s SAN Management Appliance and a Web browser. Virtualized RAID Sets (Vraid) 16 July

5 The EVAs emulate RAID levels 0, 1/0 and 5, but do so in the context of the virtualization pool. Application LUNs in a pool are virtualized and assigned any Vraid level up to a maximum capacity of 2TB each and can be expanded dynamically to meet a business s changing needs. Vraid options for the EVAs are presented to the storage administrator in three levels. Vraid 0 (or no redundancy ) corresponds to the traditional RAID level 0. Vraid 1/0 (or high redundancy ) corresponds to the traditional RAID level 1/0. And Vraid 5 (or medium redundancy ) corresponds to the traditional RAID level 5. HP, however, calls them Vraid 0, Vraid 1 and Vraid 5. Administrators divide the storage pools into disk groups (pools), which can range anywhere from eight to 240 physical disks in size, and then select the amount of capacity to dedicate to each level of redundancy; the management software takes over and determines the best way to set up the Vraid virtual disks to meet the administrator s needs. Data is then striped evenly across all available capacity in the virtual disk group. Because there is no manual disk allocation process, and because they typically work only with a few disk pools, the management process is simplified for the administrator. Capacity can be either added dynamically to an established storage pool or used to create a new virtual pool. When added to an established pool, the EVAs provide a Vraid Storage Pool Load-Leveling algorithm that automatically redistributes data across the virtual disks. Distributed Sparing Like all storage systems targeted at the midrange or above, the EVAs feature hot-sparing capability. When integrated with the virtualized architecture, however, the traditional hot spare technology is enhanced. Rather than setting aside a physical disk drive to act as a spare in case of a drive failure, the EVAs use distributed, or virtual, sparing, where capacity equal to the size of a physical drive is drawn from the overall storage pool to create a virtual hot spare. Users should keep in mind that virtualization and distributed sparing are not added protection against nonredundancy. Virtual disk LUNs that are defined as Vraid 0 (striped, but not redundant) will lose data if a physical drive used in the Vraid virtual disk fails. Upgradability According to HP, the EVA3000 is upgradable to the EVA5000 by swapping out controllers, GBICs and internal cables and upgrading software licenses the key point here being that data does not have to be reloaded. At the present time, however, the EVA3000 and EVA5000 racks are different. The EVA5000 is scalable from the low-end 2C2D model up to a 2C12D model by first adding drive enclosures until 12 enclosures are reached in the base cabinet, and then adding an expansion cabinet with six additional drive enclosures and in some cases a Fibre Channel Patch Panel. This can be done at the customer s site. The disk drives, disk enclosures and storage management appliance are reusable across the EVA line. Plans HP s plans for the EVA Series include: Support for VCS v3.0 for HSV100 controllers (that is, the EVA3000) is expected in 3Q03. This will provide support for HP s Continuous Access EVA remote copy application. Support of Linux and Novell NetWare for Secure Path with clustering was originally expected in 4Q02 and is now expected in 2Q July

6 Support for out-of-band management is planned for 1H04.

Analysis Storage Management Software The EVA 3000 and 5000 are managed using the OpenView Storage Area Manager and CommandView EVA device management products. With the introduction on the EVA3000 and renaming of the original EVA to EVA5000, HP made some changes to its storage management software offerings and streamlined the naming conventions of the products. Today there are four products: HP StorageWorks CommandView EVA for basic array management. This product includes functionality formerly called HSV Element Manager and is delivered as part of the HP OpenView Management Appliance II. HP StorageWorks Business Copy EVA for local mirroring. This product includes functionality formerly included in Enterprise Volume Manager (EVM) and Snapshot VCS. HP StorageWorks Continuous Access EVA for remote mirroring. This product is currently supported only on the EVA5000. HP StorageWorks CommandView EVA CommandView provides the graphical user interface (GUI) for the EVA, as well as basic array management for the storage systems. It is accessed via Web browser and enables the configuration and management of the EVAs. This includes the ability to view and reallocate storage through graphical mapping of host and storage status and host to array volumes, as well as management of selective presentation of LUNs on the EVA. CommandView is Web-based, enabling remote management. It also provides the link to HP s point-in-time copy and remote copy replication capabilities. CommandView EVA comes as part of the HP OpenView Management Appliance II. HP StorageWorks Business Copy EVA 16 July

8 Business Copy EVA is a new product that provides local replication capabilities for the EVA products. Business Copy EVA combines two functionality sets, formerly known as EVM and VCS Snapshot, and into one product. The former EVM functionality is called Business Copy Enhanced Mode and provides a replication job-scripting environment. The former VCS Snapshot functionality is now called Business Copy Basic Mode and includes three different types of point-in-time data replication Snapshot, the Virtually Capacity-Free Snapshot (Vsnap) and the Instantaneous Snapclone which are invoked via the CommandView EVA Storage System Scripting Utility (SSSU) or the Business Copy Enhanced Mode user interface included with Business Copy EVA. Both the basic and enhanced modes come together in the Business Copy EVA package, which is licensed using a capacity-based model based on replicated capacity. Snapshot In the snapshot method, a virtual copy of the data in the source virtual disk LUN is snapped off, and any changes that are made to those data blocks are stored. Disk capacity equal to the size of the virtual disk LUN being copied must be reserved before the snapshot process is initiated. This is done automatically as part of the snapshot process. The target of the Snapshot will have the same Vraid protection as the source. Vsnap HP s Vsnap implementation combines the snapshot process with the EVAs virtualization capabilities to allow the Vsnap to be taken without first reserving any storage capacity. Since only modified blocks take up copy space, the Enterprise VAs can accommodate those capacity requirements by dynamically taking unused space from the disk group pool. This statement is based on the fact that Vsnap stores only the last version of the modified block and the assumption that the 80/20 rule will generally apply (80 percent of the repetitive update writes will be applied to 20 percent of the data stored). Assuming that, at most 20 percent of the EVA s capacity would need to be reserved for Vsnap update writes. According to HP, this is often the case by default anyway, as the pool capacity is typically managed at a threshold setting of 75 percent to 85 percent. Customers should keep these caveats in mind when evaluating the EVAs against their needs. The Vsnap can provide disk-based recovery should a restore be required, or it can be used to do a background backup to tape. As with the traditional Snapshot, the target virtual disk LUN will have the same Vraid protection as the source. Instantaneous Snapclone The Snapclone is a variation on traditional cloning. Cloning allows a full physical copy of a volume to be made for use in environments where high performance and long retention periods are the norm. Traditional cloning is significantly slower than snapshot copying (and can have delayed access) because the processing is done in the background so that other operations taking place in the foreground experience no performance hit. With HP s Instantaneous Snapclone, however, the physical copy is virtually instantaneous because a logical point-in-time Vsnap copy is taken of the virtual disk and then copied physically onto unused space in the storage pool in the background, resulting in two copies (one logical, one physical) and the data being accessible even before the physical copy is finished. The virtual disk LUN representing the Snapclone can be accessed immediately, and if the information requested hasn t yet been copied to the clone, the EVA will access it from the production volume via the block-mapping pointers. HP s Instantaneous Snapclone target has the same full Vraid protection as the source. After the background copy of the Snapclone completes, the target Snapclone LUN is a complete copy of the source LUN, allowing the Snapclone to be the source of a subsequent remote mirror copy if disassociated from the source LUN. HP StorageWorks Continuous Access EVA Continuous Access EVA is HP s remote replication solution for the EVA Series. This array-based solution was just introduced to the EVA family in April 2003, when the EVA5000 renaming and enhancements 16 July

9 were announced. Currently only available on the EVA5000 (with VCS v3.0 installed), Continuous Access EVA provides synchronous copy remote mirroring between EVAs. Campus, metropolitan and continental distances are all supported. Some of its functionality includes: Automation of the remote mirroring and disaster recovery process. Management of remote mirroring through the Storage Management Appliance II. GUI interface for OpenView Storage Management Appliance II that allows up to three users to monitor (passive) in addition to the one (active) administrator. Unidirectional and bi-directional replication between arrays. Log report generation that is specific to the mirroring and disaster recovery environments. Failover and failback. Up to 64 copysets within an array. Other Storage Management Products and Applications VCS HP s VCS handles such functions as managing disk utilization efficiency, dynamically expanding storage capacity and workload rebalancing (after capacity is added to the virtual pool). The VCS software and license kit is a required option on each EVA model. The EVA5000 currently ships with VCS v3.0 for HSV110 controllers, which supports both Business Copy EVA and Continuous Access EVA. Customers with existing EVA5000 installations that are using VCS v2.0a for HSV110 can utilize Business Copy EVA v.2.1 or v2.1a, but must upgrade to VCS v3.0 and purchase the additional Continuous Access EVA license in order to get support for Continuous Access EVA. The EVA3000 currently uses VCS v2.0 for HSV100, which supports Business Copy EVA v2.1 but does not support Continuous Access EVA. However, HP plans to provide upgrade kits for the HSV100 controllers (that is, the EVA3000) to VCS v3.0 for HSV100 in 3Q03. This will allow EVA3000 customers to support Continuos Access EVA and provide remote replication capabilities. Secure Path Secure Path provides multipathing capability for the EVAs and other StorageWorks products and is a required option for most operating environments in order to support multiple HBA s per host. Secure Path comes in different versions for each supported operating system environment. It enables automatic failover and I/O load balancing in Windows NT, Windows 2000, Windows Server 2003, HP-UX, IBM AIX Sun Solaris, NetWare and Linux environments. Single-path support without Secure Path for all platforms (except IBM AIX) was added in July Support for Secure Path with Linux clusters is expected in 2H03. OpenView Storage Management Appliance II Managing the EVAs requires the use of a common, shared management appliance that connects directly to the SAN fabric but that is positioned outside of the data path. It features an Intel Pentium III 1.3GHz processor, 1GB of memory, a diskette drive, a 24x IDE CD-ROM drive and two 18GB hard drive, and provides configuration, management and monitoring functions for all the SAN elements. The OpenView Management Appliance II is capable of managing up to 16 Enterprise VA controller pairs (as well as up to 25 EMA16000/EMA12000/MA8000 controller pairs) in one fabric. 16 July

10 The EVA Series was the first StorageWorks product set to require that an HP OpenView Storage Management Appliance be installed in order to manage the storage system. While the EMA/MA Series products can also be managed through a Management Appliance via an HSG Element Manager, it is not required for that series. The EVAs cannot be managed using the StorageWorks Command Console (SWCC), available for the EMA/MA Series.

13 . Competitors HP EVA3000 The EVA3000 competes with the EMC CLARiiON CX400, IBM FAStT600 and Sun Microsystems StorEdge According to HP, the EVA3000 also sometimes competes against the IBM FAStT700. However, specification for specification, the EVA3000 is more closely aligned with the FAStT600. Both products are included in the comparative chart below for reference; however, this discussion will focus on the FAStT600 as the IBM competitor. The EVA3000 offers more raw storage capacity (8.2TB) than all but one of its competitors. The CLARiiON CX400 scales up to 8.8TB using Fibre Channel drives (13.5TB if ATA drives are installed). The FAStT600 and StorEdge 3510 max out at 6.1TB and 5.3TB respectively. All of the competitors support two RAID disk controllers, with all but one supporting 1GB of cache per controller (2GB cache per controller pair). The exception is the FAStT600, which supports only 128MB of cache per controller (256MB per controller pair). All four products in our competitive lineup are end-to-end Fibre Channel arrays, and all support 2Gb Fibre Channel throughout. The CLARiiON CX400 and StorEdge 3510, however, support both FC-AL and FC-SW host connectivity, while the EVA3000 is FC- SW only and the FAStT600 is FC-AL only. The CLARiiON CX400 also has the added flexibility of ATA disk support on the backend, for those customers who do not require the performance of Fibre Channel disk drives. Each of the competing products offer a similar fault-tolerance feature set with one exception. The CLARiiON CX400 does not support battery backed-up cache. Instead, the CX400 utilizes supplemental power supplies to provide enough battery power to destage data in write cache to disk in the event of a power failure a different but equally effective solution. More product differentiation can be found in the high-availability feature sets of these products. While all support automatic failover/failback, alternate pathing, environmental monitoring, remote diagnostics, nondisruptive microcode updates and clustering capabilities, the products differ in their abilities to support point-in-time and remote copy facilities and phone-home capabilities. Neither the FAStT600 nor the StorEdge 3510 support point-in-time copy one reason why potential customers might look to the IBM FAStT700 as a competitor for the EVA3000. The FAStT600 is marketed as an entry-level storage system for workgroup and small department storage consolidation and, as such, does not support point-in-time copy. Similarly, the FAStT600 and the StorEdge 3510 do not support remote copy, though in this case, neither does the EVA3000. HP has indicated that it plans to add support for its remote copy facility (Continuous Access EVA) in the 3Q03 time frame, however. Finally, the StorEdge 3510 is the only competitor in our lineup that does not support phone-home capability. The StorEdge 3510 can provide alerts and pages to the user via Diagnostic Reporter; however, Sun Services cannot act on those alerts. Sun customers would have to upgrade their services to the StorEdge 3900 or StorEdge 6900 level in order to obtain full phone-home support. The EVA3000 has one of the best standard warranties in our competitive lineup. At three years on-site with a next-business-day response, it matches the warranty offered on the FAStT600 and surpasses the others. The CLARiiON CX400 has a two-year on-site warranty with four-hour response a faster turnaround than the EVA3000 or CLARiiON CX400 but for a shorter duration. The StorEdge 3510 comes standard with a two-year warranty the first year is on-site with a second-business-day response, and the second year is a 15-day parts exchange. Most vendors offer warranty upgrades for type of service, duration or response time, but they are, of course, chargeable options. 16 July

HP EVA5000 The EVA5000 competes against the EMC CLARiiON CX600, IBM FAStT900, Hitachi Data Systems (HDS) Thunder 9570V and the Sun StorEdge HP also sometimes markets it against the EMC Symmetrix, IBM Enterprise Storage Server Model 800, Hitachi Data Systems Lightning 9970/9980V and Sun StorEdge 9970/9980 products when mainframe connectivity is not required. When mainframe connectivity is required, HP leads with its StorageWorks XP Series, which is the hardware equivalent to the Lightning 9970V/9980V and StorEdge 9970/9980 models. For purposes of this comparison, however, we will compare the EVA5000 to its midrange class competitors. The EVA5000 supports up to 240 drives or 35TB tying the CLARiiON CX600 for the highest raw capacity in the competitive mix. This is a change from our last look at this competitive lineup in December 2002, when the EVA5000 and the CLARiiON CX600 tied for the lowest capacity in the group despite supporting the most disk drives per storage system in the competitive mix. Since then, both HP and EMC have added support for 146GB drives on these products (HP in March 2003, EMC in mid-december 2002), and they now have the largest raw capacity in the group. Potential customers should also note that EMC has added support for 250GB ATA disk drives on the CLARiiON CX600, which increases the potential raw capacity of this disk array to 58TB for those customers who require greater overall capacity and are willing to sacrifice some of the performance achievable only with Fibre Channel. 16 July

16 The EVA5000, IBM FAStT900 and StorEdge 6960 each support a maximum of 2GB of controller cache per system. The Thunder 9570V supports up to 4GB of controller cache, and the CLARiiON CX600 scales to 8GB. All of the products in the competitive lineup support end-to-end Fibre Channel, though only the EVA5000, CLARiiON CX600, FAStT900 and Thunder 9570V offer 2Gb Fibre Channel to both host and disk. The StorEdge 6960 comes standard with a 1Gb Fibre Channel switch for host connectivity, but that is upgradable to a 2Gb Fibre Channel switch if the customer chooses. Backend connectivity on the StorEdge 6960 is 1Gb Fibre Channel. And as mentioned above, the CLARiiON CX600 now provides an additional level of flexibility to potential customers with the addition of ATA connectivity on the backend. Three of the competitors on our list offer some level of storage virtualization with their products. The EVA5000 has storage system-level virtualization. This is designed to improve storage utilization both through basic Vraid configuration and the distributed virtual hot-sparing function. Like all virtualized storage solutions, it also minimizes the stranded capacity problem that some storage systems face. HP s on-the-fly leveling algorithm provides automatic tuning whenever new capacity is added to the system in a virtual pool, and its distributed sparing methodology enables all storage in the storage pool to be utilized efficiently. The Thunder 9570V offers virtualization assists, which HDS categorizes as features that complement higher levels of virtualization by improving performance, rather than virtualization products themselves. HDS implements these virtualization assist capabilities within the arrays using Host Storage Domain port level virtualization and selected software applications to manage performance levels. By virtualizing at the port level, the Thunder 9570V is able to support multiple heterogeneous platforms attached to a single port. Each physical port can therefore support up to 128 virtual ports, each able to isolate and provide separate secure host domain groups with their own LUN 0 designations. Each host storage domain can support up to 512 LUNs. The StorEdge 6960 uses Storage Virtualization Engines (SVEs) to provide virtualization capability, allowing pools of storage to appear as one device to the host operating system. Because the StorEdge 6900 products are based on Sun s T3 Arrays, Sun opted to add the virtualization functionality via standalone SVEs in order to preserve customer investment in the T3s. While this method limits the controllerbased functionality provided, it does make the added functionality storage system independent. The 6960 ships with four SVEs, which are located between the hosts and the storage arrays and provide the StorEdge 6960 with physical access and multiple I/O paths to its T3 arrays building blocks. The SVEs are connected to the host and backend storage via a redundant pair of Fibre Channel switches and are redundant and host independent. All of the competitors in our lineup currently offer similar fault-tolerance and high-availability features. As with the capacity metric, this is a change from our previous look when the EVA5000 was missing support for remote mirroring. Finally, the EVA5000, like the FAStT900, comes standard with a three-year on-site warranty. The Thunder 9570V also comes with a three-year warranty, but only the first year is on-site. The rest is return to factory. The CLARiiON CX600 and StorEdge 6960 come standard with only two-year warranties, both of which are on-site. Of course, most manufacturers offer warranty upgrades in both service type, duration and response time for an additional fee. 16 July

Strengths New EVA Model The addition of the lower capacity EVA3000 model marks HP s continuing effort to fulfill its stated objective of carrying the EVA Series forward as a replacement product for the EMA/MA and Virtual Array Series. Virtualization Increases storage utilization efficiency with pooled capacity and distributed sparing and simplifies storage management through the use of self-tuning algorithms and provisioning by high-level attributes. Multiple Data Replication Techniques Supported The EVAs support three different methods of point-in-time copy data replication: traditional snapshot copy, Capacity-Free Vsnap and Instantaneous Snapclone, providing increased flexibility for the storage administrator. Fully Wired Cabinet Simplifies the ordering process and allows easy deployment. Limitations No Remote Copy Facility on Lower-End Model While HP has now managed to add remote mirroring capability to its EVA5000 product, the capability is still pending on the EVA3000. HP has stated its intention to add support for remote copy to the EVA in the 3Q03 time frame. Given its track record for 16 July

19 late implementations of this capability, however, customers are advised to either request guarantees or wait and see if remote copy is a requirement for their planned implementation. Recommended Gartner Research Disk Array Storage: Comparison Columns, DPRO Storage Virtualization: Perspective, DPRO Insight HP has made three important additions to its EVA line in the past two months. First, it added support for 146GB drives in March 2003, doubling the available capacity of the various models and eliminating one of the limitations of its previous EVA model. Second, with the release of its enhanced (and renamed) EVA5000 product in April 2003, HP added the long-awaited support for remote mirroring. This again eliminated one of the key competitive disadvantages of the previous product. Third, HP introduced the new, lower-end EVA3000 in April 2003, adding more depth to the line that is going to be the company s future for the midrange. The key now will be for HP to follow through in a timely fashion on its commitment to add remote mirroring support for the EVA3000 in 3Q03. Doing so will not only make the EVA3000 more competitive in the low end of the midrange enterprise segment, it will also go a long way towards reducing customer apprehension about the company s ability to deliver on such planned enhancements. 16 July
