What are Blade Servers?

Company News/ 23rd Feb 2010/Chris James

A funny thing has been happening recently….

We’ve had a few sales enquiries about our HP Blade dedicated servers that ask whether these are based on shared servers, virtualised machines or share resources between them. Upon following this up it would appear that an un-named, so called “competitor” has been putting the word out that this is what a “blade server” amounts to.

We had a good laugh about this over at Clook HQ and can only assume that said “competitor” either suffers from a severe lack of knowledge about the industry in which they operate OR employs the tactic of lying to try and get the sale. We’re still trying to decide which is worse!

To clear up any confusion we’d like to publicly state that our Blade Dedicated Servers are in no way virtualised or based on shared hardware in any way. Technically there are shared elements in that they are powered and cooled by PSU’s and fans within the blade enclosure itself but all server components such as CPU(s), RAM, hard drives, main board, etc are all contained within each blade chassis just like older style rackmount (or even desktop) server hardware. Blades used for our dedicated server line are not clustered or linked together in any kind of resource pooling way.

Blade technology is a fairly new development in hardware design allowing servers to fit into a smaller space and use less power meaning that we can get more servers per rack with less harm to the environment (by using less power). In addition, due to all components coming together as one package from the vendor (in our case, HP) the machines are considerably more stable and last a lot longer in full use.

This comes at a cost though with this kind of enterprise level hardware costing quite a bit more than cheaper, home built servers. While this does affect our costs we feel it’s money well worth paying in return for the much better stability we get in return along with the lower stress levels involved with having servers online performing well instead of broken, unstable or in urgent need of replacement (causing customer downtime throughout).

For anyone wanting more information about blade servers, and to see a picture of the exact blades and enclosures we use (HP c7000 Enclosure full of BL460c blades) please see the link below:
