I'm going to be mounting 2x SSD for ZIL and 2x SSD for ARC, then 20-2TB drives. I'm guessing that with a random I/O workload, I'll never hit the 1200MB/sec peak that the 4x SAS can sustain.
Also - for the ZIL I will be using 2x 32GB Intel X25-E SLC drives, and for the ARC I'll be using 2x 160GB Intel X25M MLC drives. I'm hoping that the cache will allow me to saturate gigabit and eventually infiniband. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
