Maximum Number of LUNs on XP512

[Robin King]

Dows anyone know what the maximum number of LUNS you can allocate with an XP512 is?

Hi,
If I remember right, HDS 9960 (equiv. HP XP512)
at full extension (4 chip pair, 32 interfaces ...) You could have up to 8,192 LUNs...
I believe XP512 should be the same...

All the best

Hi again Robin,
I went around www.hp.com/go/storage.. and looked at what HP put for XP512...
I undestand better your question now...
Have a look at:

The max number of lun's on an XP512 is 4096.

This is based on 512 Drives being loaded in your system.

Okay thanks guys.

Can anyone tell me how many LUNs on the XP512, can be remotely copied at any one time.

[Victor BERRIDGE]

What do you mean by remotely copied at one time?
On a second bay?

best regards

Sorry it was a bit general.
I'm trying to find this out for a client.

For DR purposes data will be copied off site, using CA (Continuous Access), similar to EMC's SRDF. Apparently there is a maximum number of LUNS that can be copied site to site at any one time.

Frank is correct : 4096 is the maximum Logical device support, since a device has 2 paths...
(true for XP and HDS...)

All the best

I dont know the answer, so the best would be I call HDS tomorrow morning and ask them...

All the best
