I am looking at buying three servers, and trying to figure out which storage solution makes the most sense in terms of performance and cost.
Total budget is around: $10,000.
OPTION 1: Dell servers with RAID 10 (4 Drives) each 7200RPM SAS 500GB, for a total capacity of 1TB. Each server is approx: $3000. Total storage then across all three servers is 3TB.
OPTION 2: Same Dell servers with a cheap single drive no RAID for $2000 and go with a centralized SAN solution.
The biggest problem is that I haven't been able to even find a SAN solution that is a reasonable price. Dell entry level storage servers are like $15,000. I am thinking just iSCSI, not fiber (too expensive).
What do you guys recommend?
