It looks like December is going to be the big month. New servers, software and all. I have been pushing this off as long as possible because of the time it will take to set everything up. but we just cannot play with fire anylonger. Some of our servers are approaching end of life and we still have critical systems running on them.
The time is here to spend the money and make everything fully redundant. We are a small company, but when you are hosting websites for fairly large companies, you just cannot have your 4 year old Dell Poweredge running the critical database portion. If that server went down right now, we would be out of commission for 1 and a half days at least. Well really we could be back up in 4 hours, but running really really slow. As the fast solution would be to restore our databases to a different location then our webservers (there is not an extra DB server at our colo facility). Websites going over a vpn to hit the database = SLOW.
Really our 2 main servers at the colo facility can already handle a fair virtualized load, 2 dell poweredge with dual quad cores, soon to both have 16 GB of ram. the plan? Server 08 R2 Enterprise running Hyper V. We need to purchase one extra server to run the Hyper V managment server, but we can then run 4 instances of server 08 on each server.
The Hyper v manager is supposed to let you easily setup failover OPs on multiple servers running hyperV. So we should be fine splitting our server load between the 2 servers and if one decides to die, no down time, everything on the dead server fails over to the good one. We only have 4 critical system, so that works out perfect. anything else that dies with the dead server can wait for the dell technitions to come via NBD support contract.
The part that I’ve been dreading is the conversion. Right now we have one server virtualized with Virtual Iron and one two stand alone server that boot from our Equallogic SAN. the plan is to first migrate the 2 standalone OPs to virtual iron and have everything running on that one server. Then install Server 08 on those 2 stations, migrate everything from VI to HyperV. And Finally convert the VI station to HyperV and loadbalance the OPs.
That does not sound like fun to me. What it really sounds like is a December full of working Saturdays.
