Hello,
Does it make any sense to use a bunch of 15K SAS drives as L2ARC
cache for several TBs of SATA disks?
For example:
A STK2540 storage array with this configuration:
* Tray 1: Twelve (12) 146 GB @ 15K SAS HDDs.
Alternatively, you can purchase non-Sun 500 GByte read-optimized SSDs.
OTOH, if the disks are already in place, then you can experiment with
L2ARC devices and, if you don't like the results, zpool remove them from
the pool.

* Tray 2: Twelve (12) 1 TB @ 7200 SATA HDDs.
I was thinking about using disks from Tray 1 as L2ARC for Tray 2 and
put all of these disks in one (1) zfs storage pool.
This pool would be used mainly as astronomical images repository,
shared via NFS over a Sun Fire X2200.
Is it worth to do?
Thanks in advance for any help.
Regards,
Roger
