We are hosting a FileMaker DB on a server consisting of 5, RAID 1+0 146 GB SAS drives. (RAID 1+0 is often recommended for hosting FileMaker databases due to high read/write occurances, versus a RAID 5 configuration).
However, we need to expand memory capacity so we purchased 3 additional 146 GB SAS drives for the server. At this point, there are several options (here are two):
1. Push the drives into the RAID 1+0 and continue to use our logical partitions (6 OS, liveDB on on partition and backups on another, 2 hot spares?). It doen't seem like this would be the best use of our hardware; two hot spares seems like a waste.
2. Keep the RAID 1+0 (5 drives for live DBs, OS partitions, hot spare) and use (3 drives) RAID 5 for backup files. However, we only have one RAID controller and I am concerned about performance with this configuration. It's worth mentioning, in this configuration, that we would backup files from the RAID 5 often ( on a network SAN ).
Does any one else have a suggestion?
