FWIW, (and you can find info about it in mailing list archives) I just built and about to out it into day-to-day use 8.2-stable system, working as big-just-in-case archive with sources from Mar1 based on SuperMicro case/mobo with LSI SAS2008 + LSI expander + 24 SATA RE4 disk bays. For now (and array is only half filled with disks) I'm very glad to have one-thread 500 MBps+ read stream from raidz2 array ;) Booting from mps (while I had to set up gmirror, as only 12 disks are exported to BIOS, hence very large raidz's are not allowed to boot from) was not a problem either. -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
