I am building this to spec for another department- we did not spec hardware or otherwise, I'm just configuring it.
I have 2 servers connected to an HP MSA 500 via SCSI. I can see the raid array on the MSA from both servers. However if I create a drive on one of the servers, the other does not see the partition- it sees the entire raid as unallocated. We want to carve it up with different drives for different servers and apps, some of which are wanted to be shared between the two servers.
Essentially it's 1TB Raid 5 array
Server A should have a 200gb and a 100gb volume.
Server B should have a 200gb, and 100gb volume.
Both servers should see the remainder, split in half (2 drives).
The only 'partioining' that can be done at the controller level is to make multiple raid sets and mask them to the particular servers. We have 1 raid set. If we were to go to multiple raid sets, they hardware owners need to buy more drives.
Both servers are running Windows 2003 Server Standard R2- no Cluster services- both are stand alone servers and will be running different apps, they just want to share the storage in the MSA.
I'm not a storage guy, and my only experience is with EMC (Clariions) and FC. That I understand. Standalone SCSI I understand, but this is all new and Google is currently NOT my friend.
Right now I am inclined to say that what they want to do is not possible without 2 raid sets and file shares for the drives that they want both servers to access (eliminating the performance of local SCSI for the remote server). Am I right? Is this possible without buying any other storage or apps?
Thanks
