Data Center presentation —
Submitted by Peter Jenkins — posted on 2011-08-23 16:39 — comments: 2

I recently presented a summary of current data center trends and technology to an audience from Jyväskulä University. I wanted to share these slides with the audience because they include some useful links for further information. I'm sure others will find these slides useful.

The topics covered include:

  • What is driving data center innovation?
    • Web scale computing
    • Economics and Metrics
  • Air cooling trends
  • Separating hot and cold air
  • Liquid cooling
  • Modular buildings/containers

How to configure ssh keys on HP C Class blade enclosures —
Submitted by Peter Jenkins — posted on 2010-08-05 15:39 — comments: 0

Couldn't find this online so I thought I'd share it here.

If you want to add an ssh key to a HP BladeSystem Onboard Administrator do this at the prompt:

> set script mode on

Script mode now in effect.

[SCRIPT MODE]> add sshkey UnIqUe_StRiNg
ssh-rsa realkeyomitted user@hostname
UnIqUe_StRiNg

Note that you can't have password and ssh key authentication for a single user so you'll need to create two administration users, one for password auth and one for ssh key.

I'll leave the reader to decide what they think of this functionality!

Grid in Financial Services and Science: a comparison —
Submitted by Peter Jenkins — posted on 2010-06-10 15:39 — comments: 0

I recently presented at HP-CAST in Hamburg, Germany. The title was "Grid in Financial Services and Science: a comparison" to a tutorial session called "Portals, Grids, Clouds".

I hadn't intended to talk about clouds initialy but I decided to change the content to fit the tutorial session. I was quite pleased with the end result and the reception I got was pretty good so I thought I'd share the slides here.

Feel free to start a discussion on the points I raise.

I'm really pleased to be able to start blogging about the work I'm doing here at CSC.

I don't expect to post that frequently, but when I do I'll be sharing fairly technical and specific information in the hope that is will save someone some time.
