separate drives for WAL or pgdata files

Hi,

 

I am not sure if there’s an obvious answer to this…If there’s a choice of an external RAID10 (Fiber Channel 6 or 8 15Krpm drives) enabled drives, what is more beneficial to store on it, the WAL, or the Database files? One of the other would go on the local RAID10 (4 drives, 15Krpm) along with the OS.

 

This is a very busy database with high concurrent connections, random reads and writes. Checkpoint segments are 300 and interval is 6 mins. Database size is less than 50GB.

 

It has become a bit more confusing because I am trying to allot shared storage across several hosts, and want to be careful not to overload one of the 2 storage processors.

 

What should I check/monitor if more information is needed to determine this?

 

Appreciate some suggestions.

 

Thanks,
Anjan
