A week of interesting technology

Last week I had the opportunity to use a number of interesting technologies and applications. I've already blogged about the Cisco Network Assistant, but that was only the beginning.

We were running a VMware Server virtual machine that was not performing correctly. The physical hardware was not up to the job, so we wanted to migrate the VM to our ESX server. The VM was configured to use a virtual IDE disk which prevented us from importing it directly into ESX. Enter VMware Converter. This piece of software allowed us to step through a wizard where we selected the source VM files, and then entered the server name we wanted to save the machine. A few other options later (selecting the destination datastore and similar), and the conversion process started. Twenty five minutes later it was all done. The converted VM had been streamed into place and was ready to go. Really simple and worked first time. I was impressed!

The end of the week gave me the opportunity to experiment with Sun Logical Domains (LDOMs). This hypervisor based VM technology can be found on the Coolthreads range (using the new sun4v architecture). Unlike Containers, LDOMs allow different Solaris versions to be installed. We're testing the performance of the machine to run as an Ingres server, so I'll most probably update the blog later this week with more information.

This week looks equally promising - Apple's WWDC was yesterday, although I haven't watched the keynote yet. The 3G iPhone isn't unexpected, but is now quite tempting, even with a £35/month contract as I can't think of a better mobile web browsing device. And then there is the announcement of "MobileMe" (aka, "Exchange for the rest of us"). It's certainly something to look into to...
