I'm running an exchange server (2003 standard) and am getting backed into a corner here in terms of my server and free space for the private/public store to grow in. They're not terribly large in size, approx. 30gbs between them but since the server is kind of old we're down to about 2gbs of free space. We can't add a new raid array to the server (no room) so I'm trying to find options that are a) cost effective, b) efficient, c) easy to deploy.
The only two options I've come up with is either getting something like the buffalo tech eSATA raid box which comes with an ESATA card for the server and move the private/puclic store there or buying a NAS solution. My only concerns about implementing NAS is that it's going to clog the network with traffic to and from the server and bottleneck performance from actual workstations trying to connect to exchange or other data servers. Is there a way to connect a NAS unit directly to the exchange server so as to avoid bogging down the entire network for read/write access, or any other solutions where we can add some fast-access storage to the server? Thanks in advance.
