hello i would say: it depends if you fill your pool with large videos or media files, i suppose its ok, but if you have things like databases or webserver, you will need only good iops values, much more than you can have with spindles. (ssd could be 100x better than disks for this use)
in this case, i would suggest to have a ssd read cache >= 80GB and a separate (strongly recommend as mirror) log-write cache (could be much smaller, 4gb+ is ok). do not try to build slices to use one ssd for read and write cache. you will hate yourself in case of errors. even with newest zfs version, you cant import a pool with missing log-drive on a new system for example after a system crash . also if you use dedup especially with only 8gb ram, you will not be happy about without ssd caches. you could use also much slower and smaller system drives. gea <br> www.napp-it.org -free webgui for opensolaris- -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
