I am looking at ways to improve performance of our databases. We have 4 large databases (ranging between 50gb and 200gb each) on a single SQL Server 2005 Cluster. Currently they are split 2 on one LUN and 2 on another. I am looking at ways to improve the IO performance of the databases as they are quite IO intensive. I have been investigating options to create 6 LUN's and reduce the number of MDF files for each database from 8 to 6 and then spreading the MDF's across all 6 LUN volumes. Currently we have 16 disks for LUN1 in RAID 10 and 16 disks for LUN2 RAID 10. If I proceed with the changes I am investigating then we would have 6 LUNS with 6 disks each in RAID 10. 1 data file per a database will sit on each LUN. Should this improve performance? does anyone have experience in this area that they could share?
