My server upgrade is near the end now.  Following up to my previous two problems encountered… To solve problem #2, I simply made the shelf a bit bigger.  There really are not many problems that can’t be fixed without a hammer.  In this case, a hammer and a chisel.  Here’s the modified server rack:

Here’s the complete server rack with all the goodies (cable modem, network switch, wireless router, UPS and MediaPortal PC with a 1 terabyte USB drive attached:

As for the problem with the blog, my initial suspicions seem to have been correct.  After disabling the WP SuperCache plug-in, everything stayed stable for a couple of days instead of this blog getting hung up once or twice a day.  I’ll try tuning the plug-in to use a different file-locking method to hopefully avoid the lock-ups and/or maybe I’ll upgrade to Wordpress 2.7.1 to see if that helps.  I’ve been meaning to upgrade Wordpress anyways…  On the bright side, disabling WP SuperCache isn’t so bad because the ESXi web server is so much more powerful than the old server that serving the Wordpress pages dynamically is actually fairly responsive on the new system.  On the old system, dynamic pages were horrificly slow unless I served static cached pages.   I still think caching is a good idea overall so I’ll keep working on it.

I also upgraded ESXi to Update 4.  This was a total no-brainer.  All you need to do is use the VMWare Infrastructure Update client that comes with the VMWare Infrastructure client (make sure to select the Update client during the install!) and the Update client does everything.  Reboot and ESXi is updated.  Updating the VMWare tools on the guest systems is a breeze too.

I like when updates and upgrades go well!
