There is alot there to reply to...but I will try and help... Re. TLER. Do not worry about TLER when using ZFS. ZFS will handle it either way and will NOT time out and drop the drive...it may wait a long time, but it will not time out and drop the drive - nor will it have an issue if you do enable TLER-ON (which sets time out to 7 seonds). I run both with TLER-ON (disks from an "old" mdadm raid array) and without (TLER-OFF) 1.5TB WDEADS.
I can not speak for the WD EARS, but the WDEADS are fine in my home nas. I also run 1.5TB Samsung Green/Silencer series and Seagate 11's. Others swear by Hitachi. I would recommend the Samsung or Hitachi and not the new WD EARS which have that 4k sectors or whatever it is. Re the CPU, do not go low power Atom etc, go a newish Core2 duo...the power differential at idle is bugger all and when you want to use the nas, ZFS will make good use of the CPU. Honestly, sit down and do the calculations on power savings of a low power cpu and you'll see it's better to just not have that 5th beer on a friday - you'll save more money that way and be MUCH happier with your nas performance. re. cards...I use and recommend these 8-Port SUPERMICRO AOC-USASLP-L8I UIO SAS. They are cheap on e-bay, just work and are fast. Use them. You do want alot of ram I use 8GB, but you can use 4. Ram is cheap, ZFS loves ram, just buy 8. IMHO (and that of the best practice guide) - you should mirror the rpool (o/s disk). Just buy 2 cheap laptop drives and when installing choose to "mirror" them. I hope that helps. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
