Hi All ; 2 TB limit on the 6000 series will be removed when we release CAM 6,1 and cyrstall firmware. I cant give an actual date at the moment but it's pretty close.
The same will happen for 2500 series but it will take some more time.

The limitation existed in every Sun branded Engenio array we tested - 2510,2530,2540,6130,6540. This limitation is on volumes. You will not be able to present a lun larger than that magical 1.998TB. I think it is a combination of both in CAM and the firmware. Can't do it with sscs either... Warm and fuzzy: Sun engineers told me they would have a new release of CAM (and firmware bundle) in late June which would "resolve" this limitation. Or just do ZFS (or even SVM) setup like Bob and I did. Its actually pretty nice because the traffic will split to both controllers giving you theoretically more throughput so long as MPxIO is functioning properly. Only (minor) downside is parity is being transmitted from the host to the disks rather than living on the controller entirely. -Andy ________________________________ From: [EMAIL PROTECTED] on behalf of Torrey McMahon Sent: Mon 5/19/2008 1:59 PM To: Bob Friesenhahn Cc: zfs-discuss@opensolaris.org; Kenny Subject: Re: [zfs-discuss] ZFS and Sun Disk arrays - Opinions?

The Solaris LUN limit is gone if you're using Solaris 10 and recent patches. The array limit(s) are tied to the type of array you're using. (Which type is this again?) CAM shouldn't be enforcing any limits of its own but only reporting back when the array complains. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
