v3 v4 1 Number of servers: 41 1 = Report: Infrastructure = 2 2 3 Number of computers: 19 3 [wiki:projects/leadership-committee/dec-2008/agenda Return to Agenda] 4 4 5 Number of locations: 5 5 This reports provides an overview of our Internet infrastructure. Most of infrastructure is composed of servers which are located in colocation facilities. A colocation facility is a space specifically designed to house computers. Typical colocation facilities have redundant power supplies, extensive cooling systems, and a series of cabinets where the servers are installed. We also use nonprofessional colocation facilities - meaning that they are setup in our offices and private locations. 6 6 7 Co-located servers: 8 7 A cabinet is like a stand-alone wardrobe. Server computers are typically shaped like pizza boxes, which slide into the cabinet to maximize the use of the space. 8 8 9 Shared-production servers: 5 9 A single physical server (pizza box) sometimes can have multiple virtual servers on it. A virtual server is a server that acts and operates like a single physical server, but in fact shares its host server with other virtual servers. Virtual servers allow us to provision a complete system to a member without having to purchase a new physical server for each member. 10 10 11 Mail-list servers: 2 11 Some servers we manage ourselves (meaning we run software updates and installations). These are managed servers. Other servers are managed directly by our members. 12 13 * Total number of servers (physical and virtual): 51 14 * Staff-Managed servers: 45 15 * Number of physical servers: 19 16 * Number of virtual servers: 26 17 * Non-Staff managed servers (all physical): 6 12 18 13 Shared-production servers are backed up immediately via RAID and once a day to the backup servers. 19 * Number of colocation facilities: 5 20 * Telehouse (professional, 25 Broadway): 12 physical servers 21 * XO (professional, 111 8th Ave): 6 physical servers 22 * HostMySite (professional, Delaware): 1 physical server 23 * Lair (non-professional, Daniel's basement): 1 physical server 24 * Sunset park (non-professional, MFPL office): 5 physical servers 14 25 26 * Allocation 27 * Standard servers (used for web and email; malcolm, chavez, viewsic, etc.): 5 28 * Email list servers: 2 29 * Backup servers (onsite and offsite): 4 30 * Member-dedicated servers: 9 31 * Host servers for virtual servers: 8 32 * Domain Name service: 4
