I was wondering if anyone could comment from experience on sizing L2ARC ssd caches.
Given: Server memory is 256GB
Pool size: Hundreds of TB (most is archival - rarely used)
Typical Data Frequently Accessed: Oracle SMB serving standard Windows CIFS home directories (some Linux, but it's 1 Linux user to ~50 Windows users)
I was thinking 1x-3x system RAM which would put me around 400-800GB.
My interconnect is SAS2, so I'm thinking of 2x the Hitachi SSD800MH in 400GB size.
Would anyone recommend 3x-4x the Hitachi SSD800MH in 200GB size for extra iops?
Thanks,
AUPhil
