That’s better!

After discovering last night that my newly acquired Broadcom 57810A Dual Port 10Gb PCIE Copper (RJ45) Ethernet NICs didn’t fit my Supermicro AS-2022TG-HIBQRF, I was pleased to find they do fit my Supermicro AS-1042G-LTF.

And best of all, absolutely no setup/configuration was necessary. I simply powered down the host, replaced the NIC and powered back up. The ports automatically assigned the same as the NIC I removed.

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).

It has been far too long since I blogged. Work has been keeping me busy 7 days a week but here’s a quick post about a recent challenge.

I have been working on several data migration projects and have been struggling in general with sluggish SQL query performance. Most of the research conducted has suggested the primary bottleneck is disk IO (rather than throughput or CPU speed) so I decided to try and find the fastest "reasonably priced" SSD to give me a boost. I found this list http://www.storagesearch.com/ssd-fastest.html and after research each of the items (for availability and cost) I chose the OCZ Revodrive3 X2 PCI-e SSD.

I ordered the SSD and installed it in one of my spare servers (SuperMicro X8SIL-F, Intel X3470, 16GB Kingston RAM). Despite not being listed on the OCZ compatibly list http://www.ocztechnology.com/displaypage.php?name=revodrive_moboguide the SSD was detected during post. Again, despite being listed as only compatible with Windows 7, the SSD was detected in Windows 2008 R2 and after installing the driver and initialising the disk in Server Manager appeared in "My Computer".

Unfortunately after installing SQL Server 2008 R2 and loading a few database up the machine mysteriously restarted and no longer was the drive listed in "My Computer" or device manager. After further reboots the SSD was no longer showing during post (various green and blue LEDs were still lit so it wasn’t completely dead). I tried the card in an old Dell 9150 I had kicking around- nothing. Then a spare HP Microserver N36L- again, nothing.

Fairly convinced now that the SSD had died I called eBuyer up and started the RMA ball rolling along with placing an order for a new card (this was Thursday night and fortunately they were able to guarantee Saturday delivery). I also ordered a motherboard from the compatibility list- ASRock Z68 Extreme4 Gen3, an Intel i7 Quad-Core 2600 3.4GHz Sandy Bridge processor, and 16GB DDR3 RAM along with a no-name case all from Amazon (again, with the guarantee of Saturday delivery).

I put everything together and fired it up:

One of the first things I noticed was the different number of chips present on each of the SSD boards (compare this to the one at the top of the post?). But regardless, the replacement was working and still going strong after 24hrs solid use.

Keeping an eye on various counters in Windows I’ve seen the card reach over 1000MB/sec- impressive! And no longer does the disk seem to be the bottleneck, it now appears to be the CPU- doh! Unfortunately it looks like some queries only utilise a single processor core so the CPU is actually only 12.5% utilised.

That’s all for now! It looks like I was just very unfortunate with the first card but the replacement is blindingly fast and a great price (especially when compared with the competition).

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)
