I might sum up here from recent additions (replies) on this mailing list
regarding current low-power server options (x86/32bit) for XS:
1) FitPC2i - Dual Ethernet, fanless, poss heat-issue (heat sink),
PhoenixBIOS (no Wake-on-LAN), 12W draw (poss ~5W idle)
2) SolidLogic - (VIA C7, 25W draw) current sys in use not available for
purchase, EU options in links below
deployment sites: Jamaica
3) MSi WindBox - '10 Atom D510, 4GB DDR2 - ~35W, drawback single Ethernet
NIC (USB WiFi adapter)
deployment sites: Nepal, Haiti, Philippines
4) EPC-AT270 - Dual Ethernet (Wake on LAN), fanless, drawback '08 model
Atom N270 (2GB DDR2) -
deployment sites: PNG, Oceania?
These solutions generally haven't changed in the last two years, in Q2,
2012 now these are the current stable options for low-power x86?
If that's the reality, I assume we can make a decision around these
options, taking site specific considerations into account, and plan for
possible involvement (replacement) down the line (1-2+ years) with any
future server development for ARM/plug/etc and what suitable working model
is devised around it.
