thanks for the info folks. We are looking for about 3-5 Tb of storage, connected to our two servers via ISCSI and shared out from the servers. Mainly just files at this point, but possibly also email (probably using Kerio mail server, if I have my way!)
We currently are using about 150 or so Gb, but I want to leave plenty of room for expansion and for email storage. :-) We have Gigabit fiber between my office and the building where I was planning on putting our storage appliance, so there's plenty of bandwidth. We have 5 Mb metro E at our "backup" location and currently only 2 Mb Metro-E at the main location, but that's easily fixed with a phone call to order more bandwidth. :-)
