CERN CASTOR Hardware Setup –2 nodes CASTOR name server –6 nodes CASTOR+SRM ATLAS (2 stager, 2 DLF, 2 SRM) –6 nodes CASTOR+SRM ALICE (2 stager, 2 DLF, 2 SRM) –6 nodes CASTOR+SRM CMS (2 stager, 2 DLF, 2 SRM) –6 nodes CASTOR+SRM LHCb (2 stager, 2 DLF, 2 SRM) –6 nodes CASTOR+SRM "Public" (2 stager, 2 DLF, 2 SRM) –a few others for "ITDC" environment (testing) / dev / test Hardware manufacturer –HP and Dell

CERN CASTOR Hardware Machine model –HP DL380 G5 and Dell 1950 Number of processors per machine –2 Number of cores per processer –2 for the HPs and 4 for the Dells Processor clock speed –2.33GHz Hyperthreading –No

CERN CASTOR Hardware Memory size –8 or 16GB Local disk size –73GB Redundancy –dual power supplies –mirrored local disks –5 NIC (2 storage, 2 private, 1 public) Clustered storage type –NAS

CERN CASTOR Hardware Storage manufacturer –NetApp 3020 and 3040 Storage RAID (0, 1, 5, 1+0 etc) –RAID-DP (double parity) Storage space (raw) –Fibre Channel disks (10k rpm) and SATA disks –41.1TB Storage space (after RAID) –32.3TB Redundancy (dual channel etc) –Two paths to storage

Hardware Plans GridKa –New server in Spring 2009 PIC –None Triumf –3D,FTS - add a new 2-node cluster and storage by April 2009 –LFC - monitor performance, review situation at least each year, before renewing hardware support contract. NDGF –We are planning and have been planning to have a 3-node cluster for some time now. It looks like the storage system will be SAN with 4Gbit/s FC and SAS disks. Nodes will be something adequate, maybe dual Quad-core Xeons with 8 or 16GB of RAM.

Hardware Plans CNAF –Just installed: 10TB of SATA storage (for flash recovery area) and10 TB of FibreChannel storage (4Gbit) The Storage device is the same CX3-80 mentioned before. This new storage will be mainly used for INFN services, but some of it can be allocated to 3D or LHC experiments clusters if needed. CERN (CASTOR) –renewal of the HPs, not decided yet, blades likely SARA –We're in the process of purchasing new hardware.This process should be completed within a few months.

Hardware Plans ASGC –as outline in server spec, we plan to add new instances into same rac group but base on different profile from which the remote management is more stable and robust enough comparing with current solution adopt. CERN (3D) –probably to DELL blade systems, storage not known yet. RAL –SAN redundancy –failover on CASTOR

Group Questions When do you replace hardware? Is the 3D kit old now? Priorities for redundancy? Switch redundancy? How much is DBA involved in procurement? How much does sysadmin know about databases? Is warranty important?
