Modeling Availability
Sep 19th
In my work I often deal with availability of infrastructure, especially when storage is involved. I am surprised by the enormous amount of completely different ways people think about availability and try to put it in workable specifications. From those variations and from various books that cover (parts) of this subject I have developed my own working model and apply it whenever possible.

Maintenance
This month’s maintenance-run yieled no problems – except that the next morning, there was a list of logfiles but none was available for review. A known issue – matter of wrong order, unless I decide to keep the files available for a few more days. Anyway – I got the mail stats:

This time due to the annual summer holiday. But the save- and scan jobs have done their job properly:

New workstations setup
It’s been some time before I could do anything else but setting up the working environments – apart from OpenVMS, of course, since Diana runs like a charm….
There has been a lot of work at home, and the datacenter had to be set aside for some time. Just letting it all run as before, except for the ususal access at times, and there has been little time to do whatever was needed to keep the PC’s happy.
At some point, however, I ran into a laptop with a 17-inch wide screen that has a separate keypad. This is a nic e feature to have when you’re planning to run Alpha Emulators with openVMS. And this one came cheap (relatively), with Windows 7 Pro 64-bit and office 2010 Pro, a 640Gb disk and can easily be extended to carry 8Gb memory.
