With xCAT I used the imagex capabilities to clone a machine (virtual machine) with vCenter on it and now I’m installing that captured image to another virtual machine. One reason I do it this way as opposed to creating a VM Template is that now I’m able to deploy to physical and virtual servers. In […]
I had the opportunity this week to test drive xCAT on HP blades. I had a c7000 chassis with some spiffy BL460c G6s. The configuration is very straight forward. We’ve updated the xCAT Install Guide to include how to configure the blades and I think we’ll be doing a lot more. Currently on these blades […]
Ever since 2001 I remember hearing the same thing about xCAT: “The documentation needs improvement”, “There is a steep learning curve”. Back in those days the quick xCAT-mini-howto was a great way to get going. The problem is that it left out a lot of the important details like service nodes, offloading tftp servers, etc. […]

Downloading firmware for Intel Servers is a bear. IBM has tried to make it easier by providing an update CD that has all the various subsystems in it. This is a pretty good idea. But the problem is, in my world, I need to PXE boot all the servers to an image or run a […]
