Planning a VMware ESX deployment on IBM BladeCenter H - Part 2

In the previous post I covered the network design for a HS21 with 4 network interfaces. This post will continue with a diagrammatic representation of the interface table.

As described previously, this configuration provides full network fault tolerance on all levels: adapter, port, CAT5, switch bay and core switch.

Put your finger over any individual constituent part, i.e., pNic, interface, bay switch or core switch, to simulate a failure and there will always be an alternative path.

I'm waiting for the customer to decide on whether to include the CFFv daughtercard in this phase of the project, and will update this post with the new design if required.

Next up, environmentals...

Those of you familiar with the HP c-Class blades will probably know that there is a superb tool called the HP BladeSystem PowerSizer 2.9, I've been trying to find an equivalent from IBM, but as yet have not found anything that comes as close. (Any pointers will be appreciated)

Instead I've had to resort to using data obtained from The Edison Group study titled Blade Server Power Study - IBM BladeCenter and HP BladeSystem, Nov 7 2007, document titled "BLL03002USEN.pdf".

The results show, in summary a BladeCenter H chassis with 14 blades on full load will need 14,352.51 BTU/Hr with a peak power consumption of 4,208.80 Watts. Most modern datacenters with good power feeds will be able to accommodate that kind of load. Cooling requirements will be left to the customer to calculate.

Additionally, this single chassis will require 9 rack units and 4 power feeds due to the additional 2900W power supply modules.

Part 2.... Continued..

Thank you Aaron for your help with the power sizer.

Here is the output from the tool (not as nice as HP's offerring by the way)

In the next part... network design for the x3650.

Well the customer has decided to not go for the CFFv daughtercard for this phase so there won't be a design update to accomondate this. If they had went ahead, it would have meant that they needed two extra Cisco GbE switches for bays 7 and 8.

If you are still curious as to how a 6 pNic design looks like, I'll cover that in the Part 3, for the x3650.

There is an IBM Power Tool:

I will actually be doing a series on both IBM and HP Blade Power, including the tools over at my site:

Thanks Aaron. New post with power and config settings now live.
