John, How much data do you have in Gigs or Terabytes now in centralized file storage now, and how much data did you have 3, 6, 12, and 18 months ago?
Also, how much data do you have on local workstations that you would be moving to centralized file storage? Finally, if I recall correctly, you only have a few handfuls of users, correct? Your disk performance requirement may not justify you pulling file storage off of your DCs. I would look at the server performance and confirm whether or not performance is suffering before spending significant dollars on a NAS, much less, a SAN. Jonathan L.

I want some sort of separate machine to get the "file server" role off the DCs. Maybe that means a NAS, maybe it means a SAN, maybe it means a server with DAS running Windows Storage Server. At this point, I'm not really sure what the best money would be. Whatever we get, I want it to be expandable so that as we (hopefully) grow, we can add more storage as needed. I do like the idea of having tape to back up whatever we have. If we're going to have email in-house, we're likely to end up with at least a couple terabytes of data in the long run, so whatever archival backup we end up with is likely to need to be a library, instead of just an on-board tape drive.

Especially for your data set size. Why do you think you need a SAN? versus NAS? versus well architechted DAS with decent tape?

This is business-critical data, although we could live without it for a couple or three days, it would be very difficult and time consuming to recreate much of the data on the servers. For this reason, I want redundant disks, network, controllers, etc. I believe I previously mentioned that my CEO told me we could live with taking up to 3 or 4 days to recover the data, but after that, it would be problematic. Personally, I'd like to get it down to under 48 hours to recover (not 4 business days, 48 actual hours.) That's why I want redundant controllers or if I can't get redundant controllers on the storage appliance itself, I want redundant storage appliances, such that the data itself is redundant. I would not like to have to go to the CEO and tell him "sorry, we lost the data because the system crashed and we had no backups." Theoretically, I could have one "appliance" and a tape library and be good, but I'd prefer to have it a *little* more robust than that. -----Original Message----- From: Steven M.

Disk redundancy? Controller redundancy? Site redundancy? Link redundancy?... If the answers to any of the above are "yes", to what degree? You can go nuts with this stuff... as has been mentioned before, what are your business requirements driving this architecture? -sc > -----Original Message----- > From: John Aldrich [mailto:jaldr...@blueridgecarpet.com] > Sent: Thursday, September 23, 2010 3:28 PM > To: NT System Admin Issues > Subject: RE: SAN question > > Well, I *would* like to get the storage off the domain controllers and have it > set up in some way that there's lots of redundancy.
