Hi all,
I'm currently spec'ing a replacement for a SQL server and considering the best approach to storage. The current server is configured based on Microsoft's historic recommendations of RAID1 arrays forO/S and Logs/Backup and RAID5 for Data.
I'm trying to weight up the best approach to move them forward and obviously replacing the RAID5 with RAID10 is a no-brainer.
For background, I'm looking at 14x 15k SAS disks for the IOPS requirement and the customer has asked for 1Tb usable storage for the data.I've opted for 146Gb disks as they are cheaper to meetboth requirementsand give me more spindles in the array than using 300Gb disks.
What I'm undecided on is whether to:
1). Place it all on OBR10
2). Separate the O/S on a RAID1 and use a single RAID10 for all the SQL data/logs etc.
3). Place the O/S and Logs/Backup on separateRAID1 arrays &...
