hi all, I am hoping to move roughly 1TB of maildir format email to ZFS, but I am unsure of what the most appropriate disk configuration on a 3510 would be.
based on the desired level of redundancy and usable space, my thought was to create a pool consisting of 2x RAID-Z vdevs (either double parity, or single parity with two hot-spares). using 300GB drives this would give roughly 2.4TB of usable space. I am presuming I will want the RAID module purely for the additional caching, and create a single LUN for each disk and present those to ZFS. the disk will most likely be directly attached to an X4100/X4200 using MPxIO, exported via NFS (some Linux NFSv3 clients, some Solaris 9, 10 and Nevada). I would like to get a feel for what others are doing in similar configurations. is the 3510 RAID module cache effective in such a configuration? I wasn't able to find any definitive answer to this in the documentation. RAID module or no RAID module? is it worth the extra cost? any insight other ZFS users could provide would be appreciated. grant. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
