I don't know why, but I feel compelled to defend myself a little (or
should that be justify).
No, the V880 does nothing for my carbon footprint. However, since I got
it, I have powered down 2 hungry HP PA-RISC boxes, 2 small SGI boxes and
2 Sun Ultra 5s. Soon a 3rd U5 will be powered down. Everything that
those machines did is now being performed by the V880 running Solaris 10
with about 6 zones. On the green aspect, I suspect that on the whole my
total power consumption has gone down slightly. Further advantages are
easier administration, improved throughput and a huge simplification in
the cabling of my "data centre" (actually the back end of the garage).
The fact that I have the ethernet RSC port configured as the console
means I never need to bring my laptop (or myself) to the garage - a
blessing in the winter or when the car is in there. Total CPU
utilisation has increased, but I still have plenty of reserves.
So what is left powered on? From ADSL modem to a small hub, to a pair of
old Dell boxes (600MHz Celeron) that act as an OpenBSD firewall cluster,
to the main switch connecting the V880, the U5 still running for a
while, a monitoring PC (Debian GNU/Linux), my desktop PC (also Debian,
with W2K running under VMWare) and a wi-fi thingy that talks to my
laptop. That's my current network.
I got the V880 of ebay at a very good price (£1,200 for 4 X 750MHz
UltraSPARC III + 16GB memory + 12 32GB disks). In a brief moment of
madness I considered a fully stocked E10K instead (only another £200),
but then sanity returned when realised that I could not afford to run
it. Now that would really have blown any green credential I might lay
claim to :-)
