I work in office of 20 or fewer people depending on the day. We currently do most of our business computing in the cloud, and only use a server for file, print sharing. Each employee also has a mapped drive on the server for "personal" files. The server used to be used heavily for accounting software, exchange, files etc but we've moved that to outside providers.
My boss and I are looking to also move the file's to the cloud as well with possibly a NAS system that backups to Egnyte every day. We have a company that has approached us to implement this but we feel we can do this much cheaper on our own.
Currently we are running a Dell Poweredge 2800 with 5 176GB 15K RAID 5 drives in the server and upgrading these drives to larger capacity will cost roughly $600 per drive if we stick with a similar type of drive.
Here's a link to the Egnyte solution we're looking at.
My question is could we get a NAS system, load it with VMWARE ESX, and do all of our file sharing without a decrease in speed? So, maybe striped drives to make up for slower RPM (7200 vs 15k)? I am not extremely versed in NAS systems or Server hardware so keep that in mind.
Note: All we really work with around here is Excel and Word files, some pictures, no big files really. We would probably keep the server going for DHCP and maybe print sharing and because it's already there.
