Test-system upgrade

Our spam-filter test-system cluster is made up of a bunch of ancient commodity PCs, Dell Optiplex’es and HP Vectras. It is a functional mirror of our production cluster, but with much less capacity. Two frontends, a number of backends, mostly single Pentium II 400MHz with 384Mb RAM. Generally not much to write about except it has just celebrated it’s tenth anniversary and replacement is really way over-due.

Performance- and capacity-wise it’s still perfectly adequate, and would likely remain so for another few years. However, it needs a new harddrive every now and then¬† and parallel ATA/IDE drives are getting quite scarce. Second, when compared to e.g. a virtual setup, it’s simply using up way too much electrical power.

Internally, we’ve discussed moving to a virtual setup more than once, usually every time a harddisk needs replacing, but it’s not a priority nor is it critical, at least not at the moment.

Hello world!

A “Hello world” post seems like a perfect wperjessen-wikilogoay to begin our new engineering blog. I’ve had this idea nagging at me for a while now, but despite us having set up plenty of WordPress sites for our customers, we never really found the time to start one ourselves. Well, here it is – the idea is to give our customers, friends, families and anyone else who’s interested an insight into the comings and goings of an IT engineering firm.¬† All ENIDAN employees are free to contribute, let’s see what happens.
