I'm assembling a 88 TB ZFS NAS with 128 GB RAM. The data that is going onto it will be write-once-only binary files, organized on average as 20+ GB files, and will thereafter be subject to multiuser (<10 over LAN) random access to retrieve multiple files. I estimate the frequent working set will be around 2 TB.
What would be recommended for my boot, ZIL and L2ARC disks? I got some ideas from Best disk requirements for a ZFS setup excluding actual shared storage, and finalized on this:
- Intel 335 80 GB, 2 disks (mirrored), >0.5 times size of physical memory for swap volume, and to reduce power consumption
- OCZ Deneva 2 R Series SLC 50 GB, for supercap, and for SLC write endurance, OR
- Intel 320 60 GB, 2 disks (mirrored), for supercap
- Samsung 840 Pro Series 512 GB, 2 disks (striped)
Is there anything absolutely wrong about this setup that I can improve on? Thanks!
