Now here’s an interesting uptime challenge

I was reading through some Cisco blogs to catch-up on what’s going on in their world for a current project of mine, when I saw this blog entry for today called “Beat this uptime” from Omar Sultan at Cisco.

They have some servers with five, seven and even nine years uptime. Great, except the utilization is so low as to not warrant the electricity they’ve used. Rather than an uptime boast, these systems seem like a great opportunity for a green datacenter consolidation and save the electricity!

Hmm, I love the smell of virtualization in the morning. I emailed Tim Sipples, it will be interesting what the mainframe blog makes of this, I know that when I was new technology architect for System z they had some customers with uptime in the 3-4 year space, running millions of transactions per day and at 85%+ utilization. I never checked for Power Systems but I suspect there are many similar out there.

[Update:] Actually if you post with stats on your system uptime directly to the Cisco blog, you can win a fleece. I missed that when I first read it!

2008 IBM Power Systems Technical University featuring AIX and Linux

Yep, it’s a mouthful. I’ve just been booking some events and presentations for later in the year, and this one, which I had initially hoped to attend clashes with one, so now I can’t.

However, in case the snappy new title passed you buy, it is still the excellent IBM Technical conference it used to be when it was the IBM System p, AIX and Linux Technical University. It runs 4.5 days from 8 – 12 September in Chicago and offers an agenda that includes more than 150 knowledge-packed sessions and hands-on training delivered by top IBM developers and Power Systems experts.

Since the “IBM i” conference is running alongside, you can choose to attend sessions in either event. Sadly I couldn’t find a link for the conference abstracts, but there is more detail online here.
