    1. 1. Systems and Operations CCDs Presentation December 12, 2007
    2. 3. Services: Server Farm Systems Administration Storage Farm EZ-Backup VMware (In Development)
    3. 4. Server Farm <ul><li>Manager: Rick Polcaro </li></ul><ul><ul><li>Staff: Peggy Roberts </li></ul></ul><ul><ul><li>Randy Smith </li></ul></ul>
    4. 5. Server Farm <ul><li>The CIT Server Farm provides a secure environment for housing departmental servers. There are more than 500 servers in the facility today. The service includes 24 hour system monitoring and reboot, network connectivity, and uninterruptible power with generator backup. Servers are mounted in CIT provided racks. It is the customer’s responsibility to provide hardware and software maintenance. </li></ul>
    5. 6. Server Farm History <ul><li>The server farm began in CCC in the mid-1980s with a few Unix systems for data warehousing and research. </li></ul><ul><li>Our first departmental user was Dining. CISER soon followed. </li></ul><ul><li>Major CIT servers into the 1990s </li></ul><ul><ul><li>Instruct Machines </li></ul></ul><ul><ul><li>EZ-Remote servers </li></ul></ul><ul><ul><li>Postoffice machines </li></ul></ul><ul><ul><li>P2K Servers </li></ul></ul><ul><ul><li>Library Servers </li></ul></ul><ul><li>Server farm moved from CCC to Rhodes Hall in 1997. </li></ul>
    6. 7. Server Farm Facilities <ul><li>Raised Floor in Rhodes and CCC. </li></ul><ul><li>Emergency power and generator backups. </li></ul><ul><li>Standard electrical power consists of 120/208 vac, with 30 amp three prong receptacle. Special requests are directly billed. </li></ul><ul><li>Physical security to authorized personnel only, with security cameras. </li></ul><ul><li>Basic support, via the NOC, for 24/7 monitoring and basic troubleshooting, rebooting, and system administrator notification. </li></ul>
    7. 8. Server Farm Facilities <ul><li>Costs: </li></ul><ul><ul><li>Space is charged by the “U”, an industry standard measurement in a 19” rack – 1.75 vertical inches. </li></ul></ul><ul><ul><li>The monthly server charge = (server “U’s” * $7.60) </li></ul></ul><ul><ul><li>There will be a one time installation charge of $118 per server </li></ul></ul><ul><ul><li>The cost for a network connection(s) and NUBB will be charged directly to the user’s University account by CIT NCS. </li></ul></ul>
