I wrote down my plan and I calculated the costs , I'm not sure if it helps anyone but it might give someone like myself (at the beginning of the road) an overall idea.
110£ (after cash back) for Hp N36L Microserver P/N: 633724-421 (
http://www8.hp.com/uk/en/campaign/proliantmicroserver/offer.html)
More specs for the box can be found on the internet
It’s a basic box with a dual core AMD Athlon II Neo N36L / 1.3 GHz
It can take 4 HDD, but it can be “hacked” to take 5 even 6 HDDs
35£ for KVR1333D3N9K2/8G - 8gb of basic non ECC DDR3 ram
75£ for 3 x 250 Gb 7200rpm HDD (The box comes with a 250GB 7200 rpm Hdd )
Total = 220£
The set-up
ESXi 4.0.1 of a flash drive
FreeNas/Openfiler/UnRaid - haven’t decided yet which one – as a VM ; I plant to implement a software RAID10 (overkill) or a RAID5; Role: storage, NZBd/torrents, print server
Endian Community Firewall VM ; Role: software firewall, VPN /remote control
I could add 1-2 more VMs if they are not CPU intense.
Summary:
Cost: 220£
Roles: NAS, software firewall, test lab
Space: 500GB on RAID10 or 750GB on RAID5
Power consumption: 3 or 4£ a month if kept on 24/7
I can get higher storage if I decide to spend more on bigger disks, for now this is the minimum I can get away with for a decent configuration..
