SAN external Storage

I dont know if i have this in the right place but we are going to get an external storage device and have a couple of options. first the scsi attached deviced such as the power vault from DEll and then the SAN/NAS. My question is on the SAN/NAS they seem to be stand along appliances with their own operating system, that users access throught the network, but how do i give permissions, does the san/nas attachees to my domain controllers? Im not to familiar with these devices. And what about the SCSI atthached devices that connect to the server, will the server be impacted enough to get the san/nas. (The server is a domain controller that is being used as a files server only)

I doubt you'd have problems connecting a SCSI unit to the server and adding space to the server.

As for NAS, NAS is NETWORK ATTACHED STORAGE - This is a box with it's own operating system of sorts.  Today, most, if not all, SAN devices can be configured to attach to a domain for user authentication.

A SAN is a STORAGE AREA NETWORK.  These are typically Storage devices (with MANY disks that plug in to fibre channel backbones and connect to servers as if the disk space were local storage.  A SAN can typically support more than one server).
