  2. Strategy • move to experiment/project based local computing • grid is the future for Monte Carlo and Analysis • laptops are becoming more important • move towards self management and self support of desktops David Martin / UK HEP System Managers Meeting 22/23 April 2002

  3. Equipment • > 60 Desktop PCs of ages up to ~ 5½ years • Windows 95, NT, 2000 • Linux ( RedHat 6.1 and 7.2) • 1 Tbyte File Server ~ 2 years old • RedHat 6.1 with kernel 2.2.19 + NFS3 patches • CDF • ScotGRID David Martin / UK HEP System Managers Meeting 22/23 April 2002

  4. Laptops • 8 for ScotGRID (organised by P.Millar) • 4 For CDF • 3 For Detector Developers • ?? Personal Mixture of Windows 2000 and Linux David Martin / UK HEP System Managers Meeting 22/23 April 2002

  5. Networking • within HEP - mostly switched 100baseT • dual 1GBit /s on Campus backbone • Campus LAN and WAN link are currently in a tender process for upgrade • Internet connection is via the ClydeNET-MAN/SuperJanet router that happens to be on our campus David Martin / UK HEP System Managers Meeting 22/23 April 2002
