I've ordered a new server with:
- 4x600GB Toshiba 10K SAS2 Disks
- 2x100GB OCZ DENEVA 2R SYNC eMLC SATA (no expander so I hope no SAS/
SATA problems). Specs: http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-emlc.html
I want to use the 2 OCZ SSDs as mirrored intent log devices, but as
the intent log needs quite a small amount of the disks (10GB?), I was
wondering if I can use the rest of the disks as L2ARC?
I have a few questions about this:
-Is 10GB enough for a log device?
-Can I partition the disks (10GB + 90 GB) and use the unused (90GB)
space as L2ARC?
-If I use the rest of the disks as L2ARC, do I have to mirror the
L2ARC or can I just add 2 partitions (eg: 2 x 90GB = 180GB)
-If I used non mirrored L2ARC, Could something go wrong if one L2ARC
device failed (pool unavailable,lock in the kernel, panic,...)?
