I was torn between hardware, and internet/networking sub-forums, but since this is more a hardware question, thought this went here.
I currently have a Lian Li PC-a77FB case with 4x super micro 5-in-3 carriers:
This currently does the following tasks
5 x 3TB drives in RAID 5 for Home Theater storage
4 x 2TB drives in RAID-10 for VM's of Exchange, My website, and other things (running around 10VM's at the moment)
2 x 2TB drives in RAID-1 for backups of all my machines
2x 3TB and 1x 2TB hot spares for the above arrays, in case of drive failure
All these feed off one LSI-9260-8I controller. I've worked in IT for a long time (currently work at a Cloud backup company), and I'm starting to worry about the integrity of this system, running so much off one controller,mobo, etc, so I'm looking at expanding it out into a small rack environment. I work with HP equipment at work and hate it, I've worked with Dell in the past and love it. So here is what I was thinking of doing, and wanted your opinions:
I can get a Dell Poweredge R220 for ~700$. It's haswell, so it'll use less power than an older 1950. Fill this with 2x 4TB drives in a RAID 1 array, and run either Windows Server 2012 or FreeNAS and use it strictly as my backup server. This would then have 2 x 4TB external drives connected to it, running sync software to get copies of the server onto the external drives, independently. The Backup server is incredibly mportant, as I use it for storing all my photography work, code I've written, and backups of my exchange, website, desktop and laptop. I was considering a DIY approach with a Norco RPC-1204, but the end cost would be nearly as much as the Dell, and I can get a 3yr warranty with the Dell, so it's a better option (plus ILO)
Getting a 2U poweredge 420 or older 2950 to use for the media server, and running RAID 10/RAID 5 off of it using newer 4 - 6 TB drives. This would only function as the media server, nothing else.
And last, getting a R320 or equivalent (maybe another 1950 used) and using that later for my VMs.
This would net me 3 servers, and would remove one box being a point of failure for everything going down, as well as get my backup solution entirely off the same box as everything else. Does this sound like a fair plan, or is there another option I should think about?
I haven't been on here in a while, but as always, Thanks in advance!
