Are right that X4500 have single point of failure but keeping a spare server module is not that expensive. As there are no cables , replacing will tkae a few seconds and after the boot everything will be ok.
Besides cluster support for JBOD's will come shortly, that setup will eleminate SPOF Mertol Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone +902123352200 Mobile +905339310752 Fax +902123352222 Email [EMAIL PROTECTED] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Friesenhahn Sent: Monday, July 14, 2008 3:58 AM To: Moore, Joe Cc: zfs-discuss@opensolaris.org Subject: Re: [zfs-discuss] X4540 On Fri, 11 Jul 2008, Moore, Joe wrote: > Bob Friesenhahn >> I expect that Sun is realizing that it is already undercutting much >> of the rest of its product line.

I am totally with you here since today I can not access my storage pool due to server motherboard failure and I don't know when Sun will successfully fix it. Since I use an external RAID array for my file server, there would not be so much hardship except that I do not have a spare file server available.
