I hope to be installing some equipment in a local datacenter to offer some hosting services. First item, the hardware;

  • Ubiquiti Edgerouter Lite
  • Dell 8024 (24x 10GbE Switch)
  • Synology RS3614RPXS NAS (6x WD RED 3TB + 2x Samsung EVO 840 1TB + Intel X540-T2 10GbE NIC)
  • 2x Supermicro AS-2022TG-HIBQRF (each w/ four nodes w/ 64GB RAM & 2x Opteron 6176 + Intel X540-T2 10GbE NIC)

Initially I went for a combination of the Netgear Prosafe XS708E (8x 10GbE Switch) paired with a Dell (24x 1GbE Switch) but quickly found myself running out of 10GbE ports and concerned about the lack of redundant power supplies.

Likewise, I had chosen the RS3614XS but felt the additional cost of the RP (model with redundant power supplies) was justified.

And finally the servers themselves, initially Supermicro AS1042G-LTF (single node with four sockets and single power supply) but then switching to the AS-2022TG-HIBQRF (four node, each with two sockets and shared redundant power supplies).

I’ve tried to avoid single points of failure at a component level (redundant power supplies etc) but without overkill couldn’t avoid it at device level (redundant switches, NAS etc).

Supplier wise… I got the switch from http://www.etb-tech.com/ and the NAS from http://elow.co.uk/ (both of which admittedly i had my doubts about when first placing the orders, as the prices seemed a little cheap, but the service was incredible, both dispatched same day using next day couriers). The rest from eBuyer and local suppliers.

Each device is connected to the switch using 2x10GbE LAG/LACP ports (I may go more into the configuration of this later).

New Virtual Lab – Part 1

Since I moved (about a year ago) I have been without a virtual lab- the old lab ran on 2x Dell Poweredge 2950 III & 1x HP Proliant DL385 G2, noisey and power-hungry! My intention was to run power to the garage so I could bring the lab back to life, but rising electricity costs and some interesting posts on Jason’s blog persuaded me to order some new, smaller, quieter and more green/efficient hardware:

£163 – Supermicro X8SIL-F (the motherboard Jason recommended and many seem to’ve reported success with)
£255 – Intel Xeon X3470 Quad-Core 2.93Ghz (Socket 1156)
£026 – Akasa Intel 1U 1156 CPU Cooler (AK-CCE-7107BS)
£123 – 4x 4GB Kingston 1333Mhz ECC (KVR1333D3E9S/4G or KVR1333D3E9SK2/8G)

I already had some spare 1U Supermicro chassis with power supplies (512L-200B) and USB pen drives laying around for the hypervisors.

I initially ordered one of the above-mentioned kit from LambdaTek (I intended to get comfortable with it before ordering more). Unfortunately the motherboard was on back order so I decided to look around for another supplier. I couldn’t find anywhere cheaper or with stock so i picked 2 up from an international seller on eBay. While I was at it I grabbed another x3470 from Amazon (£260), another 16GB of RAM from Crescent Electronics (£107) and another Cooler (this time the Gelid Slim Silence IPlus Low Profile Intel CPU Cooler from Cool&Quiet @ £20)

Part 2 to follow! Just a quick note about the Akasa Cooler- i’ve deliberately put a line through it because you should NOT order it (it’s no good- i will get onto that in part 2)
