Get redundant power, DRAC card, and 2nd Proc.
nevesisDRAC is unnecessary because all (?) new Dell servers come with DRAC Express/BMC. It doesn't have all the features of DRAC, but is sufficient for the vast majority (hard reboots).
jcourtneywe use separate servers for the SQL database and the kaseya server.
we recently upgrade our ram on the sql server and noticed the performance increased. So I suggest the 12 gigs of ram
I don't understand the reason of getting a drac card unless your server is co located and you don't trust them do restart a server.
As far as the redundant power supply, I'd make sure the first power supply has a good UPS then figure in a UPS in for the second power supply
all that being said, I think your server will only be limited by your internet connection.
PS:We have a couple r710s as esx hosts and they have been amazing. Oh and our kaseya server is virtual and we have not noticed a performance hit.
jcourtneyThere was a very interesting webcast for sizing servers for Kaseya. I don't remember what they recommended for your number of agent, but it may be a good idea to ask their expert on that.
