Supermicro teething troubles and voltage warnings

VMware, , ,

During my recent build of the vHydra server I found myself rather frustrated with Supermicro for a couple of reasons.

Firstly their UK distribution doesn’t seem to be working particularly well as there’s a two week wait for most parts which are apparently shipped from the US on demand. There are UK based resellers (I tried www.boston.co.uk) but even then some parts still have a long lead time (around a week) and I found them to be expensive compared to alternative web based vendors.

Secondly their technical support was somewhat lacking. Once I’d built the server I found I was getting an overvoltage warning on the second, empty, CPU socket. As I was planning on populating this socket (once the second CPU and heatsink arrived, another three weeks wait :-() I was keen to know if this was a false positive or whether the board should be returned as faulty.

I emailed Supermicro technical support who went through the usual information gathering – firmware, BIOS, motherboard details etc. They identified that the IPMI firmware was out of date Continue reading Supermicro teething troubles and voltage warnings →

Home labs – a scalable vSphere whitebox

VMware, ,

Having recently upgraded my home lab’s storage I decided it was also time to upgrade my aging hosts which date back to 2007. They’ve done well to survive and still be useful(ish) five years later but they’re maxed out at 8GB RAM and it’s becoming increasingly difficult to do anything with that. I briefly considered adding SSDs as host cache but that doesn’t address some of their other shortcomings such as no support for Fault Tolerance, VMDirectPath or any type of KVM functionality.

A quick look around the blogosphere revealed a few common options;

More power!

The problem for me was that these solutions all maxed out at 16 or 32GB RAM per host, a limitation of the single socket Xeon’s architecture. That’s a lot of memory for a home lab server today but to ensure that this server can last five years I really wanted more scalability. I wasn’t too fussed about noise as I use my cellar for my lab, and power consumption was a secondary concern. The server features of the Supermicro boards appeal to me (and many Supermicro motherboards are compatible with vSphere) so I browsed their range looking for the one that best met my requirements. My final parts list ended up as;

Must….have…more…POWER..the vHydra!

The total cost comes to around £1150. I’m branding mine the vHydra after the mythical multi-headed dragon!
Note: In the US this is significantly cheaper, coming in at $1450, or about £900.

For the money I get a powerful server that can replace all three of my current 8GB hosts and more than match their performance while consuming less power and space, plus Continue reading Home labs – a scalable vSphere whitebox →
