I''m testing it with 4x 1 and 1.5 TByte consumer SATA drives (Seagate) with raidz2 and raidz3 and like what I see so far. Given http://opensolaris.org/jive/thread.jspa?threadID=139315 I''ve ordered an Intel 311 series for ZIL/L2ARC. I hope to use above with 4x 3 TByte Hitachi Deskstar 5K3000 HDS5C3030ALA630 given the data from Blackblaze in regards to their reliability. Suggestion for above layout (8 GByte RAM 4x 3 TByte as raidz2) I should go with 4 GByte for slog and 16 GByte for L2ARC, right? Is it possible to attach slog/L2ARC to a pool after the fact? I''d rather not wear out the small SSD with ~5 TByte avoidable writes. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE

You can attach a ZIL or L2ARC device anytime after the pool is created. Also, I think you want an Intel 320, NOT the 311, for use as a ZIL. The 320 includes capacitors, so if you lose power, your ZIL doesn''t lose data. The 311 DOESN''T include capacitors. -- Erik Trimble Java Platform Group Infrastructure Mailstop: usca22-317 Phone: x67195 Santa Clara, CA Timezone: US/Pacific (UTC-0800)

Especially, if the Hitachi HDS5C3030ALA630 SATA-III disks work in the N36L at all. My guess would be that the on-board SATA-II controller will not support more than 2TB, but I have not found a definitive statement. HP certainly will not sell you disks bigger than 2TB for the N36L.

You can''t boot from them, of course, but that''s what the internal USB and external eSATA ports are good for. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE

The 311 DOESN''T include capacitors.This is basically just a test system for hybrid pools, will be on UPS in production, and mostly read-only. The nice advantage of Nexenta core + napp-it is that it includes apache + mysql + php, which saves the need for a dedicated machine or virtual guest. The appliance will host some 600+ k small (few MBytes) files. Does zfs need any special tuning for this case? -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
