What is the iSCSI performance like? Are you using iSCSI HBAs or are you using software based initiator? Also, how does it compare to 4gb FC? Joe _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Evan Mann Sent: Tuesday, November 14, 2006 1:55 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SAN solutions I'm im the middle of a NetApp FAS 3020 SAN implementation and we are also adding Dell Blade 1955's.. I have 2 separate units, primary site and colo/DR site. The primary site is a clustered box. That means there are 2 separate controllers which talk to each other. I have 2 disk shelves right now with 14x144FC drives and I have 2 QLogic SANBox fiber switches. I have a couple servers hooked up iSCSI, a couple rack servers Fiber connected (2 ports per server) and the Blade center has each blade fiber connected with 2 ports. Each fiber connected server/blade has 1 port going to each QLogic switch. The QLogic switches themselves are not uplinked to each other. The controllers have dual ports for their disk shelf and fiber switch connectors. She each one is connected to each shelf/switch, but in an alternative port setup tob asically create a large redundant loop. It's complex to explain without a diagram, but you end up with a big mess of cables with a fully clustered and redundant setup with no single point of failure. My DR site is not clustered like this, it's just single controller/fiber switch. The redundancy only comes from any directly connected fiber HBA's with 2 ports, or iSCSI servers which have teamed NICs. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Parr Sent: Tuesday, November 14, 2006 3:01 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SAN solutions Can you do a quick spec of what it roughly looks like to have redundancy with the SAN? ----- Original Message ----- From: thin-bounce@xxxxxxxxxxxxx <thin-bounce@xxxxxxxxxxxxx> To: thin@xxxxxxxxxxxxx <thin@xxxxxxxxxxxxx> Sent: Tue Nov 14 14:46:52 2006 Subject: [THIN] Re: SAN solutions You can build tremendous reliability and redundancy into SAN appliances, if you so chose. Multiple RAID disks, hot spares, redundant controllers, network paths, etc. Blades + SAN is our current direction, although we are just getting started on implementation. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Parr Sent: Tuesday, November 14, 2006 1:36 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] SAN solutions How much trust would you put in going with all blades for servers with SAN solution? Is this still not ulitmately a single point of failure on the storage side if the RAID there fails? Any stats on actual reliability?
