Thank you for helping me out in advance. I truly appreciate it. I have limited experience in scaling hardware networks beyond a certain point, and thus wanted some help. I have a small business, 30 concurrent users, but expect that to grow to about 50-60 in the next year or two. I use a few applications only
1. An enterprise ERP that runs on SQL
2. Tally (which is an account software, but is only used by 4-5 users, who are a part of the finance department)
3. Google Apps (for GMAIL), but each node has it's own outlook, and uses POP3 to check and store email locally on individual machines. Computers do not have access to internet, but have the required POP ports open via ISA firewall.
My hardware is a set of managed switches, and a DELL R200 server (http://www.dell.com/downloads/global/products/pedge/en/pe_R200_spec_sheet_new.pdf
) that currently runs SBS2003, SQL and manages the domain. I also have 1 network drive (Seagate) and 1 USB drive connected to the server for backing up on a daily basis.
I find that my server even though not completely utilized crazes once in 2 days, I haven't found out the reason why. So, I was thinking of adding another server, as a backup, in case this one fails, the other would kick in automatically. My question is, can another R200 server be good enough? Can SBS allow us to do that? Should I update to SBS 2011?
I'm also thinking of buying a backup solution, such as the Dell MD1200, MD1220 or MD3200.
Can anyone tell me if anyone is better than the other?
So in essence, I want to convert my network to be slightly more robust, with a server redundancy, backup solution, and possibly reside data heavy applications like SQL to sit on network storage as opposed to the server hard drive.
Thank you so much for your help! I truly appreciate it.
