I'm looking into moving a workstation from Ubuntu 10 to FreeBSD 7.1 (both amd64) and I'm a bit worried about storage -- specifically moving from mdadm, which performs very well for me.
Current in Linux I use an mdadm RAID5 of 5 disks. After investigating FreeBSD storage options, RAID-Z sounds optimal. I'd like to avoid levels 3 and 1 due to write bottlenecks, and level 0 for obvious reasons. Migrating from the existing mdadm is not an issue. I also do not plan to boot from the software array. Various docs/postings seem to indicate that using ZFS/RAID-Z under FreeBSD will destroy my computer, run over my cat, and bail out the investment banking industry. Will it really perform that poorly on a Phenom and 8GB RAM? Significantly more resources than mdadm in Linux? How about compared to RAID 5 under vinum? Thanks, ~Mike Manlief 1: The ability to read the array with the Linux FUSE ZFS implementation is very appealing; don't care about performance for such inter-op scenarios. Copy-on-write sounds awesome too. 2: ...and even level 5, now that I've learned of RAID-Z. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
