New Virtual Lab – Part 2

…continued from https://tickett.wordpress.com/2011/08/24/new-virtual-lab-part-1/

So- in came the first set of bits for new server #1 and I begun piecing it together…

Issue #1- The motherboard doesn’t sit quite right on the spacers/chassis screws (because of the element of the cpu cooler which sits on the underside of the metherboard)- not really a problem, I just added a few washers (I expect I may’ve been able to find some slightly larger spacers too, if i’d looked hard enough).

Issue #2- My USB pen drive didn’t fit in the internal slot with the chassis together. Not to worry- i simply attached a header to the spare pins and plugged the USB stick into one of those ports still inside the case.

Issue #3- When i powered up the machine it was pretty loud. I checked and believe this to be because the Akasa cooler (AK-CCE-7107BS) only has a 3 pin header so doesn’t support pulse-width-modulation (PWM) and effectively runs at full speed all of the time! Fortunately the other cooler (Gelid Slim Silence IPlus Low Profile Intel CPU Cooler) had the correct 4 pin connector and when hooked up, supported PWM and ran nice and quiet!

Issue #4- I intend to run the server “headless” so one of the great features of the X8-SiL-F motherboard is the on-board IPMI. Unfortunately when i tried to connect with the default username/password “ADMIN” / “ADMIN” access was denied. I downloaded a copy of the latest firmware from the Supermicro site and flashed using:

dpupdate.exe -f SMT_SX_250.bin -r n

The -r n parameter telling it to reset to factory settings. Voila- I could now login via the web-interface or windows IPMI tool using the default login credentials (“ADMIN” / “ADMIN”).

ESXi 4.1 installed like a charm but i’ve had a little trouble trying to deploy my first Virtual Machine (ESXi management network losing connectivity and/or the hypervisor crashing)- I think this might be because i’m using old knackered network cables! I will replace them and hopefully update tomorrow in Part 3.

The 2nd of these servers is on route and hopefully be delivered before the weekend.

My next question is what virtual machines should i configure?

I definitely need a vCenter server
I definitely need at least one SQL server (possibly 2 or 3 as i’d like to experiment with replication)
I definitely need at least one web server (IIS)
I definitely want to get trixbox back up and running
I am considering experimenting with pfSense or possibly untangle?
I also need a local dns server but think that might best sit on physical hardware or i’ll get problems with the hypervisor being unable to query DNS before the VM has started?
My fileserver currently runs WHS2011- So I would also like a WHS2011 VM to test the “Drive Extender” replacements on (however I realize I can’t really test performance here so might have to give that a miss).
Also, i think that OSX Server might run on ESXi- and i’d quite like to have a proper (non-hacked) time machine backup store configured so this might be the right route to go down…

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)
