Fibre Channel

On the storage course this week, I have been playing around with Fibre Channel & FC-AL. Below shows the output of luxadm, which is the Solaris utility to manage Fibre Channel. You can see the status of various GBIC's, temperatures of drives and other information. Having hands on experience with this kit in a lab allows you to play / break stuff without the worry of loosing data.

Consdering the cost of a Sun StorEdge A5000 for example, unless I was working at a company which uses them, the chance of being able to use one is slim - as I doubt most people would have one in their home. Fortunately for me, I will have access to this type of equipment in our labs, as we'll be supporting it all - so it makes sense.
