Cooling Home “Datacenters”…

So I wish I had a neat little graph to post, however it's full of holes due to my syslog/snmp monitoring server powering itself off due to thermal events...In the summer heat here in South Florida my rack gets to over 112°F.  It's in the garage due to the sheer noise and the heat that is generated, I have been contemplating a portable room a/c unit or one of those split systems but both would be a waste of energy since the garage door opens atleast 2 times a day.  All of my whitebox and my larger Dell server don't give a rats...that it's 112°F.  Only this 1U Dell PE1550 seems to care.  But in reality I can't even blame it all on that server, the rack's UPS has been needing a new battery cartridge for over 3 months so it's possible that it's dropping power and the other servers power back up and not that one...The NetBot's Device Crawler indicates that *could* be the cause with uptimes of the core network devices in that rack.  Either way I need to get to the bottom of this as I am virtualizing more and more on that 1550...I guess I'll head by batterysplus and get raked over the coals for the no less then 8 batteries in this cartridge...damn technology...

Card Access Systems for Home use…

So I picked up this Northern Computers N-1000-II Access control panel from fleabay for a few bucks.  I'm working to make my garage door have card access, and then maybe the front door of the house.  Still haven't figured out howto program it, the serial port spews out timestamps of events (alarm conditions, card reads, etc) you can program one of the 2 card reader inputs to energize a relay output when an "authorized" card is read..

New PE Server

Just got this Dell PE1950 from fleabay for a mere $55 bucks.  The guy was local so a quick drive to pick it up.  Planning on using it for VMWare, it's a dual 1.4ghz P3 with 2gb of ram.  Rack'in it was fail because it's designed for square hole racks, not my round ibm rack...(not a versa/rapid rail issue) it's like chassis has slots to fit into square holes only, I might just trim them a bit to make it fit, but meh...
