My ramblings on the stuff that holds it all together
Category Archives: Virtual Grid
There’s an interesting post over on Forrester research blog by James Staten. he’s talking some more about data centres in a container; making the data centre the FRU rather than a server or server components (Disk, PSU etc.).
This isn’t a new idea but it I’m sure the economics of scale currently mean this is currently suitable for the computing super-powers (Google, Microsoft – MS are buying them now!) – variances in local power/comms cost could soon force companies to adopt this approach rather than be tied to a local/national utility company and their power/comms pricing.
But just think if you are a large out-sourcing type company you typically reserve, build and populate data centres based on customer load, now this load can be variable; customers come and go (as much as you would like to keep them long-term this is becoming a commodity market and customer’s demand you are able to react quickly to changes in THEIR business model – which is typically why they outsource – they make it YOUR problem to service their needs).
It would make sense if you could dynamically grow and shrink your compute/hosting facility based on customer demand in this space – thats not so easy to do with a physical location as you are tied to it in terms of power availability/cost and lease period.
New suite build out at a typical co-lo company can take 1-2 months to establish networking, racks, power distribution, cabling, operational procedures etc. (and that’s not including physical construction if it’s a new building) – adopting the blackbox approach could significantly reduce the start-up time and increase your operational flexibility
Rather than invest in in-suite structured cabling, rack and reusable (or dedicated) server/blade infrastructures why not just have terminated power, comms and cooling connections and plug them in as required within a secured warehouse like space.
You could even lease datacentre containers from a service provider/supplier to ensure there is no cap-ex investment required to host customers.
If your shiny new data centre is runs out of power then you could relocate it a lot easier (and cheaply) as it’s already transportable rather than tied to the physical building infrastructure; you are able to follow the cheapest power and comms – nationally or even globally.
As I’ve said before the more you virtualize the contents of your datacentre the less you care about what physical kit it runs on… you essentially reserve power from a flexible compute/storage/network “grid” – and that could be anything/anywhere.
I have a geeky secret; I used to be really into ray-tracing and 3D graphics not so much from an “art” point of view – although I do have an interest in that and computer modelling/visualisation checks a lot of boxes for me as I always wanted to be a civil engineer or architect (well, I kind of am… but with computers..!)
it was one of the only applications I found in the early/mid 90’s that could really tax a machine and I spent a lot of time playing with large render jobs using PovRay and progressed to 3D studio for DOS and then a bit of a dabble with building render farms using 3DS Max before I had to go and get a “proper” job with less spare time.
I would love the time to get back into it, with the power available today you could produce some awesome images, although maybe I am somewhat hampered through lack of talent… maybe that will be downloadable now?
….So anyway, here’s an interesting article on how DreamWorks Animation have sped up access to their render farm using Ibrix Parallel file server software… they shift a lot of data!
I’ve worked on a project where we’ve tried to implement similar high-performance grid-based storage systems for large media files; but they were somewhat less successful/undeveloped; this one looks promising.
I wonder if these kind of vendors will start moving into the virtualization space; it’s essentially the same principal.
Deliver large flat files (.VMDK), over cheap/scalable commodity media (GigE) as quick a possible
This would reduce the depende.ncy on expensive back-end fibre channel SANs, and you could invest more in flexible Ethernet – or maybe Infiniband to deliver networking and storage within a “virtual fabric”
If it’s “virtual” and “grid” based the quality/features of individual hardware devices (DL380, NAS device etc.) that make it up the overall grid are less important and a 100% software approach gives you the flexibility to pick & choose building blocks from the most appropriate/affordable manufacturer rather than be locked into a costly single vendor solution (HP EVA, EMC Clariion, DMX etc.)
