It's actually quite simple. At the most basic level. SAN is block level storage. Things like SQL databases and Exchange, etc. LUNS..
NAS is more file level like file shares (CIFS), etc. Both can offer redundancy in their hardware, etc. Hopefully when you select a vendor you select a piece of hardware that can provide both SAN/NAS.

My understanding is that while there is a large overlap between NAS and SAN, that the SAN still has some features that the NAS does not. Some things like redundancy come to mind right off. Sure they've got RAID, but do they have redundant controllers and redundant Ethernet? The ones I've looked at don't appear to have that.

If you have a NAS, put the files on there. The NAS itself should be able to join your AD and appear as any other server. Then just share out the volume via CIFS and go. No need to go the iSCSI LUN route. Overcomplicated.. From: John Aldrich [mailto:jaldr...@blueridgecarpet.com] Sent: Friday, October 09, 2009 9:38 AM To: NT System Admin Issues Subject: RE: NAS/SAN My thought was to do the latter, but serve up the files through the existing file servers using ISCSI as if the file system were on the file server itself. We currently have two Dell PowerEdge servers handling both file/print serving as well as domain control. I want to keep the two servers, but consolidate the storage on a dedicated storage appliance.

If the latter, it sounds like you want a solution capable serving up CIFS. On Fri, Oct 9, 2009 at 7:56 AM, John Aldrich <jaldr...@blueridgecarpet.com> wrote: Thanks. That sort of talk made me suspicious that he was blowing smoke, but it seems like a good product, nonetheless, and if it comes in cheaper than the "big boys" I may go with that, especially since ASB recommends 'em.

Have you looked into Dell/EMCs CX4-120? Its the entry level CX unit that provides both fiber channel and iscsi connectivity via "UltraFlex I/O Modules". It supports 4GB/s and 8GB/s Fiber Channel and 1 GB/s and 10GB/s iSCSI. -Sean On Fri, Oct 9, 2009 at 7:39 AM, John Aldrich <jaldr...@blueridgecarpet.com> wrote: Ok, I just got off the phone with a StoneFly sales engineer.He had some interesting things to say about EMC/Dell/Equallogic/NetApp and LSI. I need some fact-checking from people who know more than I about this sort of thing. he said that those are "dumb" ISCSI devices that can't handle a lot of connections at once and that I ought to buy their product because that hardware can handle a lot more connections and a lot higher throughput than the competition. Was he just blowing smoke up my rear or is that stuff true? Thanks!
