Total Number of disks in a DG at EVA 4400

[Mathew Mengi]

What is the total number of disks that can be part of any Disk Group in EVA 4400? Is it 56? Please confirm.

[Steven Clementi]

12 x 8 = 96

EVA4400 can have up to 8 disk shelves with 12 disks per shelf.

Thanks for the response.

Steven - What I wanted to know is the total number of disks that I can have in one Disk Group in an EVA 4400. So what you are saying is 96 disks that can be in a single disk group if I read you right?

From HP WBT that I was going through it says 56 disks in a Disk Group is the maximum and 8 is the minimum. I need to confirm that.
Also the maximum number of disk groups in an EVA 4400 is 7.

Yohan\Sudhakar - Thanks for the additional reading. However I was not able to find any information in relation to my query. If yopu are able to identify an answer there for me I'd appreciate.

Below are some additional information that might be able to assist.

Disk Group parameters;

- a minimum of 8 physical disks
- a maximum of all physical disks within the array
* EVA 5000 & EVA8000 maximum is 240
*EVA 6000 maximum is 112
* EVA3000& EVA4000 maximum is 56

If you are able to clarify if the 56 is refering to the total number of disks in a disk group. Appreciate your further assistance on this.

To reiterate what Steven said: An EVA 4400 can support up to 8 shelves of 12 disks each. 96 disks total. One disk group.

Hi Mathew,

EVA 4000 and EVA4400 are different

EVA 4000 Can support maximum 4 Enclosures with 14 HDD each so maximum is 56.

EVA 4400 supports maximum 8 Enclosures with 12 HDD each so maximum is 12x8 is 96.

"Steven - What I wanted to know is the total number of disks that I can have in one Disk Group in an EVA 4400. So what you are saying is 96 disks that can be in a single disk group if I read you right?"

Yes. The EVA4400 is NOT an EVA4000... as stated above.


"From HP WBT that I was going through it says 56 disks in a Disk Group is the maximum and 8 is the minimum. I need to confirm that.

On an EVA4000, you can have a maximum of 56 disks. 56 / 8 = 7 disk groups.

On an EVA4400, you can have a maximum of 96 disks. 96 / 8 = 12 disk groups maximum.

There is a 6400 and an 8400 as well... not the same at the 6000 or 8000.
