A NAS acts like a file server. It contains its own filesystem and usually connects to a LAN, not a dedicated network. Often a NAS communicates to the client using SMB, and NFS. Many of the lower cost NAS are just a Windows system that does not let you log into it.
A SAN does not have a filesystem. It serves disk space over a dedicated network. -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of John Summerfield Sent: Tuesday, October 23, 2007 4:13 PM To: [email protected] Subject: SAN NAS People here have shown forbearance before, so I'll test my luck again;-) I know both provide disk storage on a network, and one's higher-performance than the other, but.... When is a Tb of storage a NAS and when is it a SAN? -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Please do not reply off-list ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ________________________________________________________________________________________________________________ CONFIDENTIALITY NOTICE: This email from the State of California is for the sole use of the intended recipient and may contain confidential and privileged information.
