Recommended Drive Configurations for Systems with Multiple Users
-
The recommended disk size for:
-
Drive D includes enough space for database reorganisations
-
Drive F includes enough space for two backups
-
-
Configure the database (D) and journal (E) drives for a relatively high IO throughput
We recommend RAID10 as the appropriate RAID level for these two drives
Don't use RAID 5
-
For business-critical applications, the journal volume must be mirrored
Ideally it should be duplexed – have a dual controller
-
You can improve disk performance by distributing these drives across a larger number of disk spindles
