Fixing my power consumption Part 1…
by Species5618 on Oct.01, 2007, under Computers, Geekdom, Technology
Following on the shocking revelation as to how much my toys were costing me to run
I spent satuday morning, moving data, re-writing backup scripts, and have managed to SQEEZE all my data onto the disks in the server, which has enabled me to shut down the extreemly power hungry FC storage array.
This has also left me short of space, but a USB2 external disk is on the cards for the general archive stuff !
Next will be replace the UPS. i have a belkin 600VA one lying around, that shoudl be enough now i have reduce the power to under 200 Watts
Power (oh my god)

got my self one of those domestic power meters and been around the house,
HOLY FUCK !!!!
Need to change my storage strategy, the Compaq RA4100 fibre channel chassis with 12 disk may well be over kill, but it is also DAMN expensive to run,
and I have NO idea why the UPS is pulling 100Watts with NO load !!!
??As i am only ising the storage for archive type stuff not “live” apps, I am planning to replce it with an external USB2 disk,
the Cost Recovery Period will be less than 4 months !
Not sure what to do about the server though, it is runnign AD, Exchange, VMware server with VOIP PBX and dansguardian ….
