Dear XS folks, to follow-up on the hardware threads, I have tried to sum-up some reflexions about the hardware possible to build up the XS/book-server @ our deployment in NosyKomba (Madagascar)
=Energy The electricity is produced w/ solar panel (2 x 230W) producing a 24V-DC network => we need to supply the maximum of devices/appliances in 12V/24V-DC to maximize the usage of the electricity =>A 12v-DC network is preferred because most computers/network devices power-supply are in the range 9-17V-DC (ATX power supply are producing 12V/5V/3V3/-12V from 110/220V-AC or 12v-DC) =>APC solutions with monitoring of the battery load interacting with the XS over Ethernet link could help to shutdown/halt properly the linux kernel in case of power outages ==>I am looking at how can i stop smoothly the services while powered by 12V-DC and some batteries/regulators ? =School server (separated or merged XS and Book-server) There is several propositions of hardware : =>reliable (PC-like solutions) *Advantech ARK-3440 (w/ tropicalized hard drives in RAID6) supplied in 24V-DC (usually 180W - ATX) (~= 1000€) *MSI WindBox DE500-5123 (newegg.com) - 169€ *MSI 6676-001BUS (amazon.com) + 4gb DDR2-800 200pin notebook form (CORSAIR 4GB (2 x 2GB) 200-Pin DDR2 800 at $45 and 2TB SATA hard drive (Samsung) at $80 *fitPC2 : http://www.fit-pc.com/web/fit-pc/fit-pc2-specifications/ + ssd hdd *fitPC3 =>low energy : *Sheeva or dream "plug" supplied in 12/24V-DC (ARM-based CPU) *flash/hard drives storage (ARM architecture) and connected in Ethernet/Wi-Fi (usually 10W) =>experimental : RasperriPi (less than 5W) =>ARM based : *XO 1.75 (? W) as a XS server with a usb-to-ethernet adapter for wired connexion to the lan *OpenWRT devices w/ external storage (foneras, wrt54g, ...) _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
