User:Atxbyea/HP Storageworks Enterprise Virtual Array

The HP Storageworks Enterprise Virtual Array is an enterprise storage disk array sold by Hewlett-Packard. The product was originally part of the Compaq portfolio but after the merge it was subsequently rebadged with the HP logo

It has been released in three generations (and one sub-generation) since the original launch.

First generation
The first generation of EVA was the EVA3000 and EVA5000, these were based on the HSV100 and HSV110 controllers respectively. Common features for the series :


 * 1.5U per controller (3U for the pair)
 * Has 2Gb\s host ports (Uplinks)
 * Has 2Gb\s device ports (Disk loops)
 * Either Active\Passive or Active\Active controllers, dependent on firmware.
 * 2GB cache per controller pair
 * 96 hours of battery backed cache
 * Supports Vraid 0 - 1 - 5

EVA3000 (HSV100)
The EVA3000 is the "smaller" version of the first generation.

Therefore it has only 2 host-ports per controller, 2 devices ports per controller and supports a maximum of four disk-shelves

EVA5000 (HSV110)
The EVA5000 has greater features than it's smaller brother.

It has support for up to 18 disk-shelves, has 2 host-ports per controller, 4 devices ports per controller and incorporates loop-switches, which enhances redundancy and speed of the system.

Second generation
The second generation of EVA was the EVA4000, EVA6000 and EVA8000, these were based on the HSV200 and HSV210 (these came in A revision and no revision)controllers respectively. Common features for the series :


 * 2U per controller (4U for the pair)
 * Has 2Gb\s host ports (Uplinks) (4Gb\s host ports for the -A controllers)
 * Has 2Gb\s device ports (Disk loops)
 * Active\Active controllers
 * 2GB cache per controller pair (4GB for the EVA8000)
 * 96 hours of battery backed cache
 * Supports Vraid 0 - 1 - 5

EVA4000\6000 (HSV200(-A))
The EVA4000\6000 is the "smaller" version of the second generation.

The EVA4000 only has 2 host-ports, and supports a maximum of four disk-shelves. The EVA6000 also has 2 host-ports, but has two additional loopswitches, which makes it possible to attach up to eight disk-shelves.

EVA8000 (HSV210(-A))
The EVA8000 has greater features than it's smaller brother.

It has support for up to 18 disk-shelves, has 4 host-ports per controller and incorporates loop-switches, which enhances redundancy and speed of the system.

Second generation - Second revision
The second generation, second revision of EVA was the EVA4100, EVA6100 and EVA8100, these were based on the HSV200-B and HSV210-B controllers respectively.

Common features for the series :


 * 2U per controller (4U for the pair)
 * Has 4Gb\s host ports (Uplinks)
 * Has 4Gb\s device ports (Disk loops)
 * Active\Active controllers
 * 2GB cache per controller pair (4GB for the EVA8100)
 * 96 hours of battery backed cache
 * Supports Vraid 0 - 1 - 5

EVA4100\6100 (HSV200-B)
The EVA4000\6000 is the "smaller" version of the second generation.

The EVA4100 only has 2 host-ports, and supports a maximum of four disk-shelves. The EVA6100 also has 2 host-ports, but has two additional loopswitches, which makes it possible to attach up to eight disk-shelves.

EVA8100 (HSV210-B)
The EVA8100 has greater features than it's smaller brother.

It has support for up to 18 disk-shelves, has 4 host-ports per controller and incorporates loop-switches, which enhances redundancy and speed of the system.

Third Generation
The third generation of EVA is the EVA4400, EVA6400 and EVA8400, these were based on the HSV300, HSV350 and HSV400 controllers respectively.

This generation introduced support for 32TB LUN's compared to the old limitations of 2TB, and also introduced Vraid6.

New disk-shelves were also introduced on this generation (eliminating the old EMU-hardware) which are 2U shelves with 12disks.

Common features for the series :


 * 2U for the controller pair in the EVA4400
 * 2U per controller (4U for the pair) for the EVA6400\8400
 * Has 8Gb\s host ports (Uplinks)
 * Has 4Gb\s device ports (Disk loops)
 * Active\Active controllers
 * 2GB cache per controller pair (8GB for the EVA6400 and 14GB or 22GB for the EVA8400)
 * 96 hours of battery backed cache
 * Supports Vraid 0 - 1 - 5 - 6

EVA4400 (HSV300)
The EVA4400 has a completely different design for the controllers than all other EVA's. Both controllers are situated inside a shared controller enclosure that also houses shared powersupplies but dedicated batteries.

The EVA4400 is targeted more towards smaller customers, and as such has the option of controllers with integrated SAN-switches to "directly" attach the servers to the EVA. This model has support for up to eight disk-shelves.
