i see your point but i think some people do it for high availability. for example they would have 2 partitions on the server, the first being the local disks with the OS, and then have all their apps installed on the 2nd partition being on the san. then they can snap and/or clone that 2nd partition all they want on the SAN to make it easier to recover and to image. i don't do it, but i think some people might for these reasons... _______________________________________________ Jon Luchette Emerson Hospital Technology Specialist III Work: 978-287-3369 Cell: 978-360-1379 jluchette@xxxxxxxxxxxxxxx _______________________________________________ ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Landin, Mark Sent: Wednesday, July 19, 2006 10:46 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SAN Benefits for Citrix Right. Although, if you aren't BOOTING from SAN, then you must be using local disk for your OS, swap, etc. In that case, what are you using the SAN disks for? Unless you have truly GIGANTIC application suites, I don't see why non-booting-SAN for Citrix would make sense. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Luchette, Jon Sent: Wednesday, July 19, 2006 9:30 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SAN Benefits for Citrix right but my point is that he was saying that "booting from san" would cost you more than just using the san for other disks which I don't agree with. you would need the adaptors either way... the concept of booting from san doesn't cost you anything as compared to normal use of the san on a server. _______________________________________________ Jon Luchette Emerson Hospital Technology Specialist III Work: 978-287-3369 Cell: 978-360-1379 jluchette@xxxxxxxxxxxxxxx _______________________________________________ ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jeff Matheis Sent: Wednesday, July 19, 2006 10:26 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SAN Benefits for Citrix You still need 2 adapters (for redundancy) per server, plus SAN ports, usually there is management software associated with the SAN which is licensed per connection, etc.... This person is problem referring to all of the overall costs that add about $5k or more each time you hook a device up.

How can I use the SAN to enhance my Citrix deployment (currently 15 servers, 250 concurrent users, hardware become outdated and soon needs replacement)? I was told by our SAN Admin that booting new servers from the SAN would probably be cost prohibitive.
