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.
* Tray 2: Twelve (12) 1 TB @ 7200 SATA HDDs.
Just thought I would point out that these are hardware backed RAID
arrays. You might be better off using the J4200
instead for this so ZFS can manage the disks completely as well. Will
probably be cheaper too! The savings could
be put towards some SSD's or more system RAM for L1ARC.
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
