I am bidding a project to support a company with a server farm of ~12 WIndows 2003 servers with raid 5 arrays varying from 2 - 12 TB of storage each. They do a huge amountof scanning, converting, and indexing images. I am looking for suggestions on reconfiguring the network to be more efficient. Thoughts on virtualizing some servers, i-scsi or other network storage solutions, would be helpful. At this stage I know very little more about the useage of the servers than the above, so this is preliminary research. Just links to good sources of information would be helpful.
