Virtualization, Cloud, Infrastructure and all that stuff in-between

My ramblings on the stuff that holds it all together

vTARDIS.next runs on vSphere 5.0

 

I have been working furiously on an updated version of the vTARDIS based around vSphere 5, and now it’s in the open (I was on the heavily NDA’d beta programme) the goal is the same: lowest cost possible physical hardware, but the ability to build complex production like ESX environments and run large amounts of virtual ESX hypervisors and guests.

This time round, and due to some VERY cool [UNSUPPORTED] features of ESX 5 you can run more than just clusters of nested ESX virtual machines as I did in the original vTARDIS, but you can also run all the following on a SINGLE physical server running vSphere 5 – this is seriously cool IMHO

  • Run 64-bit guests inside an ESX virtual machine (you couldn’t do this previously as it didn’t pass through the x64 extensions)
  • Run HyperV under ESX as a virtual machine, and allow it to run nested guests* and even build clusters of Hyper V servers
  • Run XenServers under ESX as a virtual machine and allow it to run nested guests – to be tested 
  • Fully stateless deployment of ESX guests using my former colleague’s amazing PXE Manager so no need to configure lots of hosts
  • Run large vSphere clusters
  • Multiple Virtual Storage Appliances

*I have had problems with the guests inside virtual Hyper-V nodes, more on this soon as I think it was just a config problem

Hardware

In the past I used the HP ML1xx range of PC-servers, they’re great bits of kit but I was starting to run into challenges with the 8Gb RAM limit, so I have branched out a bit and gone for an HP DL380 G5 – yes it’s not quiet enough to put under your bed 😉 but they are reasonably cheap 2nd hand on eBay and more importantly they take up to 32Gb of RAM. and in day to day use it’s not too noisy

Total acquisition cost of this server as follows (all from eBay and out of my own pocket)

HP DL380 G5, 2 x dual core Xeon 2.0GHz, 8Gb RAM, 2 x 72Gb SAS disks, P400 array controller, redundant PSU, iLo advanced license. £550 (Refurbished)
6 x 72Gb 10k RPM SAS HP Disks £270 (Refurbished)
32Gb RAM £520 (!) ouch new.
Sold supplied 8Gb RAM kit from server -£150
Total Cost £1,190

This box has a good pedigree as you’ll see because it’s former owners didn’t erase the iLo settings before they decommissioned it (oops).

Whilst it’s noisy as hell, it seems surprisingly frugal when it comes to power consumption with approx 50% CPU load on the physical host

Storage

Local DAS array of 8 x 72Gb SFF hot-plug HP drives, I’m also backing them up to my Iomega NAS using Veeam Backup and Replication 5.

 

Hypervisor

I did this work with the beta and Release Candidate (RC) builds of ESX and vCenter, I used the Windows vCenter installation rather than the appliance.

 

Next… The iTARDIS* more soon!

*Don’t try this at home.. you won’t be able to make it work (yet), there are some firmware issues that stop it working on a Mac Mini – but I had access to some internal resources whilst working at VMware to get around it

Stay tuned for step-by-step instructions

vPastures New

I’ve had a great time working at VMware since last year and have worked with some of the greatest minds in the industry on some interesting projects. But, after a lot of deliberation I have taken the decision to leave the relative comfort of a “permanent” position at a vendor to work on a freelance basis as an Infrastructure Architect – specialising in virtualization and cloud solutions.

My reasons for this move are varied and personal, but suffice to say that I have a number of outside ventures that are coming to fruition and I need the flexibility to work on them independently.

VMware have some great stuff in the pipeline and I’m going to enjoy working with it albeit back on the customer/partner side of the equation rather than inside, it’s also gratifying to see the cloud concepts I was working on in 2008 becoming very much mainstream – so maybe I wasn’t mad after all 🙂

VMware have some challenges and growing pains in scaling out the business and avoiding Microsoft syndrome (too much, too wide, too thin). They need to make sure that they don’t loose sight of the requirement for end-end integrated customer solutions with services and support to match. Particularly where there are so many technology acquisitions involved. That said, VMware have the best senior exec’s in the technology industry steering the ship – I can say that as I’ve met most of them over the last couple of years and they’ve been there & done it.

I will still be heavily involved in the community and need to set aside some time for vTARDIS.next and my recently neglected blog – many cool mind-bending, physics defying hypervisor inside a hypervisor posts to come!

I have some interesting professional engagements lined up and I’m looking forward to a new challenge.

Cheers
