We are installing a new SQL 2005 64 bit machine and have 12 x300GB available. Given that what would be the best RAID config? I was thinking of
OS RAID 1
SQL Binaries/Tempdb RAID 1
SQL Backups RAID 1
SQL Logs RAID 1
SQL Data 4 disk RAID 10 or:-
OS RAID 1
SQL Binaries/Backups/Tempdb RAID 1
SQL Logs 4 disk RAID 10
SQL Data 4 disk RAID 10
Would there be any gain in having a 6 disk RAID 10 for data files and then trying to consolidate the other drives. Might be difficult as really want to isolate data, logs and backups.
