I have a IBM blade server with 5 blades attached to an IBM FC san.

Xenserver 5.5 is running on each blade with blade 1,2,3 in a pool and 4 and 5 running independantly.

What I want to know is, can the same lun be attached to two installs of Xenserver.
The xenservers in the pool, 1 2 and 3 all access the same LUNs.. but can the xenserver on 4 and 5 access the same luns that are being accessed by the pool of 1,2 and 3?

Can the xenserver on 4 access the same lun that 5 is accessing?

Whoever answers, can you detail how and why this is possible or not possible.

You can certainly connect multiple systems to the same LUN.  in fact in high availability scenarios, when iSCSI is being used, this is exactly what you want to do.  However the VHD's within that LUN should only be mounted by one system at a time to avoid file corruption.

Alternatively you can utilize NFS, which has some additional benefits, but Microsoft clients (including Server 2008 R2) are known to have intermittent bugs when using NFS, some of which might affect your deployment.

Thanks Zupreme,

So If I had LUN #1 attached to Blade 4 and 5, each with a seperate install of xenserver it would still work?

How do I know that the VHDs created on each Xenserver will not overlap and corrupt each other? Is it just done by the program?
