I've found the 2100's to be very poor systems to run ZFS on top of. For all of UFS's flaws, at least you could have a reasonably performing 1U application server. ZFS is great, but you really need a pair of flash drives for the ARC and ZIL. On the 2100, that simply isn't a cost effective solution. I'd like the Opensolaris installer to be able to support UFS again, but oh well. -- Brent Jones br...@servuhome.net _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
