Generally, one Smart-UPS RT 10KVA RM per rack of 3U/2U/1U servers, UPS at the bottom, servers above. http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SURT10KRMXL6U-TF5&total_watts=1000 If packing the entire rack with 30 1U servers, I add another transformer to get 36 outlets total, with proper output power distribution from the UPS. This assume single PSU servers. I'm not a big believer in dual PSUs WRT SHV servers. http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP9626 For the 18 SAS drive FC storage arrays, I do one Smart-UPS RT 3000VA per 4 SAN chassis, along with one Smart-UPS RT 192V RM Battery Pack for ~2 hours extended runtime. http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SURTA3000RMXL3U&total_watts=1000 -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
