I know this isn't your design space, but Matt on zfs-discuss posted the following part list http://www.acmemicro.com/estore/merchant.ihtml?pid=5440&lastcatid=53&step=4 http://www.newegg.com/Product/Product.aspx?Item=N82E16820139043 http://www.acmemicro.com/estore/merchant.ihtml?pid=4518&step=4 http://www.acmemicro.com/estore/merchant.ihtml?pid=6708&step=4 http://www.newegg.com/Product/Product.aspx?Item=N82E16819117187 http://www.newegg.com/Product/Product.aspx?Item=N82E16835203002 later he added I'm just going to use the single 4x SAS. 1200MB/sec should be a great plenty for 24 drives total. 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. -- 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 _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
