  3. Seven X6250 Oracle blades do have the following configuration: 1 CPU with Quad core Intel Xeon L5430 Processor 2,6GHZ 50W. 16 GB memory based on four 4 GB Dimms. Two 146 GB SAS disk with Raid controller.

  4. One X6250 management blade : 1 CPU with Quad core Intel Xeon L5430 Processor 2,6GHZ 50W. 8 GB memory based on two 4 GB Dimms. Two 146 GB SAS disk with Raid controller. Running SLES 10.

  5. 15 TiB of netto storage is provided by a StorageTek 6540 storage array. A mix of 146 and 300 GB 15 Krpm fibre disks. A total of 80 disks with a raw capacity of 19 TiB. Disks are configured as RAID5. Performance tested with the Orion tool. (Requirement: 1 KIOPS/1 TiB)

  6. 3D: ATLAS 3 nodes, LHCb 2 nodes Other services: ATLAS LFC, LHCb LFC, FTS: 2 nodes
