My 2 mythtv backend boxes are still running on Intel P4s. Very much alive and no moral nor physical reason to replace them. Ditto for our corporate firewalls and asterisk server.
try to calculate energy needs of intel P4 vs modern 64bit cpu with sufficent power for this backends ..
[off-topic] One of these backends use about 70W when idling, which is maybe 20 out of 24 hours. It amounts to 0.25 per day in running costs. A new up-to-date box (with room for two 3.5" SATA drives) might be 300 and still consume maybe 35W. (very rough guess based on power dissipation of newer Intel CPUs). That makes a saving of 0.12 per day, thereby paying off the 300 investment in 2500 days. If I got a 2nd hand machine at 150, the investment would be paid off in 1250 days, unless the 2nd hand box used more power. I have not taken into account that kWhs are cheaper between 20:00 and 08:00. Maybe I'll put a meter on it for a full day and see the real numbers. Something powered by Intel Atoms would use significantly less power, but I haven't looked for those and I have a suspicion they wouldn't have sufficient power. -- Per Jessen, Zürich (24.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
