Clariion CX300 question

[nyck]

Hello,

Is it possible on a CX300 to create a LUN and share it between two different servers?

If so how would I be able to do this?

Cheers

Nick

In general, on any san, you cannot share a lun on the same time to 2 different servers ( and actively write to the lun ), that's all about scsi reservations.In an mscs you can share a lun ( for quota for example), where each node takes turns in doing a write, never simultanuous( the MS cluster is in charge of this )

Hope this helps

rgds,

Sure you can. VMFS does this all of the time. You just need to have a clustering filesystem on the LUN, which rules out Windows NTFS. There are a number of third-party products that allow this for Windows, and of course there are non-NTFS filesystems that include clustering out of the box (as with vmWare's VMFS).

You basically present the LUN to two (or more) hosts. How they handle it from there will depend on what those hosts are and how they handle disk management.
