Hi All, I have been asked to implement a zfs based solution using storedge 6130 and im chasing my own tail trying to decide how best to architect this. The storage space is going to be used for database dumps/backups (nearline storage). What is killing me is that I must mix hardware raid and zfs..
The storedge shelf has 14 FC 72gb disks attached to a solaris snv_68. I was thinking that since I cant export all the disks un-raided out to the solaris system that I would instead: (on the 6130) Create 3 raid5 volumes of 200gb each using the "Sun_ZFS" pool (128k segment size, read ahead enabled 4 disk). (On the snv_68) Create a raid0 using zfs of the 3 volumes from the 6130, using the same 128k stripe size. It seemed to me that if I was going to go for redundancy with a mixture of zfs and hardware raid that I would put the redundancy into the hardware raid and use striping at the zfs level, is that methodology the best way to think of it? The only requirement ive gotten so far is that it can be written to and read from at a minimum of 72mb/s locally and 1gb/35sec via nfs. I suspect I would need at least 600gb of storage. Anyone have any recommendations? The last time tried to create one 13 disk raid5 with zfs filesystem the performance was terrible via nfs.. But when I shared an nfs filesystem via a raidz or mirror things were much better.. So im nervous about doing this with only one volume in the zfs pool. Thanks in Advance, Andy Lubel PS - sorry to Richard for sending that email directly, I wasn't paying attention.. _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
