Words by Frank Dagenhardt [Tue, Nov 05, 2002 at 02:49:56PM +]: Storage Area Netorking is just a way to enable storage to be used like a utility. It simplifies management by consolidating all of your storage into a virtual pool for you to be able to draw from at any time. Enabling you to get the full use out of the storage that you have paid for. Most SANS have the ability to take advantage of cloning, snapshots, replication and virtual disks. Network attached storage is more like an optimized file server. SANS present the storage to the servers as if they were actual physical disks on the server. If you have more questions I would be happy to answer. I have, related to this last part of NAS vs SAN. Can we use SAN as a NAS? I mean, can we share (the same) central data in a transparent way among n servers? Will this work as a NAS on steroids? Is this supported/used on any platform? Are we talking about exclusive or concurrential disk accesses? Does this bring problems on data consistency? (well, every machine sees the disks as their own...) Is it possible at all?

RE: FW: Storage Area Networking [7:56857]
TIA, You could use a server connected to a SAN as a sort of NAS. I do not know what you mean by sharing the data in a transparent way amoung n serversyes you could share data from a nas amoung n servers. This NAS / SAN combo is used by many vendors. Only one machine will see the lun as its own, that machine would then share it out to the other machines, unless you used a snapshot or a clone of that disk, but then the other servers would have to be connected to the SAN.

How do you use it? How well does it work? What problems does it solve for you? It it really networking, the way we know the term?? It sounds like it's sort of the next generation of file servers, but it also sounds like it's just a new way of managing hard drives. I'm having a difficult time figuring out what it is really. Thanks for helping me understand it. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=56904t=56857 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
