I have SQL SERVER 2005 database running on windows server 2008 with following configuration SERVER:HP Proliant ML380 G7 CPU: 1 RAM: 10 GB of RAM HHD: 3*300 GB HHDs with RAID 5 configuration
It has 10 live databases and 10 history databases with different sizes from 500MB to 6GB. These databases have around 100 users who will read and write.
There are a lot of reads than writes per second, I don't have the exact statistics.
Now We're trying to upgrade our server and thinking of better RAID configuration one for the data files and the other for OS ,log files and tempdb.
Can anybody suggest me which will be the best RAID for my system?
RAID1 or RAID5 or RAID10?.
Should I go for two RAIDs?
From my search i found RAID 10 is nice, but also somebody is saying 'advantage of RAID 10 is myth',refer below article.
