We're using a x4250 with a J4400 attached for a similar configuration. However, it's running Solaris 10u8.
We have 16 disks in the x4250, 10 of which make up 2x raidz (4-disk each) groups, with 2 available hot spares. These are 300gb disks, so I'm less afraid of data loss from a parity failure. The J4400 holds 12 disks organized into 2x 5-disk raidz2 with 2 hot spares; these are 1tb disks. There is also a 146gb mirrored zil device for the 1gb disk array. Reads are random but writes are mostly linear, so spinning disks are fine and it seems to keep reads from binding during large writes. These were originally supposed to be X-25E SSDs, but we had an edge-case issue that Sun and Intel are still apparently attempting to fix. We have not really had any problems with the system whatsoever. We just use the 'shareiscsi=on' and then add a target port group. --- Karl Katzke Systems Analyst II TAMU DRGS -----Original Message----- From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss-boun...@opensolaris.org] On Behalf Of JOrdan Sent: Friday, April 16, 2010 2:42 PM To: zfs-discuss@opensolaris.org Subject: Re: [zfs-discuss] ZFS for ISCSI ntfs backing store. Thanks Scott. I really appreciate your feedback. I'm curious about the number of disks, raidz/2 setup information? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
