Hardware

Historical Note

At first I thought this was going to be running your own servers in your own (air-conditioned) rooms. I mean how 20th Century But its local mini servers, RPis and the like. Very 21st.

What should I buy as a server?

Depends

http://www.soekris.com/ - small form, firewalls routers etc. Freebsd compatible

beagleboard - low power, single board computer. - hobbyist, aimed at wearable computers etc. http://arstechnica.com/open-source/news/2008/08/ti-launches-hackable-beagle-board-for-hobbyist-projects.ars

How to determine what hardware is running?

# sysctl -a | grep -i hw.model hw.model: Intel(R) Pentium(R) 4 CPU 1.90GHz

# sysctl -a | grep -i memory Virtual Memory: (Total: 2161196K, Active 56164K) Real Memory: (Total: 19760K Active 10812K) Shared Virtual Memory: (Total: 6184K Active: 4760K) Shared Real Memory: (Total: 4944K Active: 3668K) Free Memory Pages: 219288K hw.cbb.start_memory: 2281701376 p1003_1b.memory_protection: 0 p1003_1b.shared_memory_objects: 1

That is usually enough for one day.

#sysctl -ad Will show all measures and a description
