I have 3 servers, call them 1,2,3.  1 MD3000i with 2 Disk groups: disk group 1 R5, 3 disks, on 6 SATA drives.  Disk Group 2 on 9 SAS drives.  All three servers are connected via iSCSI to the array and mapped to the respective drive groupings via a switch.  Now, none of the servers see anything any of the other servers write to the array.  So if Server 1 puts a file  on say drive G:, which points to the 1 Tb LUN across the SAS drives, none of the other servers can see it.  This is good and what I was hoping for.

The problem is I am getting random file corruption issues.  I go to access a file and it tells me it is corrupted, I can't even delete it.  Should I just be connecting to the array with one server and sharing that connection out to the other servers over the LAN?  Somehow this seems counter intuitive to the concept of a SAN.  I do not want to partion out the LUN into smaller disk groups. 

This is what it looks like: 

 

 

Thank you,
