I have an IBM System x3500 server that at present has 3 IBM drives in a raid 5 array. I am upgrading from 2003 Server standard R2 to 2008 Server Standard R2. The drives are 73.4 Gb 10K SAS drives. I want to add a second array with 3 1 TB 10K Western Digital SAS drives in a RAID 5. Can I run two different arrays with these different size drives, and do I need a separate controller card to run this second array.
The first array with the with the smaller drives is going to run 3 servers (2 virtual). The second array is going to be the Data drive.
Can this be done as I have asked above, and do I need the 2nd controller card, or anything else?
