05/18/03Maurizio Davini Hepix2003 Summary Desktop Services Central Computing Services Cluster and Storage Lab

05/18/03Maurizio Davini Hepix2003 Desktop Services 500 desktop PCs running: Windows (XP/2000)~40% Linux ~40% MacOS (9.x and X) ~20%

05/18/03Maurizio Davini Hepix2003 Central Computing Services All central computing services migrated to Linux Central computing services: mail,login,fileservers based on SuperMicro hardware Computing clusters based on AMD Appro and SuperMicro hardware

05/18/03Maurizio Davini Hepix2003 Central Computing Services Mail server based on Stalker CommuniGate Pro The hardware is SuperMicro 6022 DualPIII with MegaRaid We have a redundant configuration: the machine is mirrored on another 6022 using MountainViewData software MvdSync

05/18/03Maurizio Davini Hepix2003 Central Computing Services All users directories are hosted on IDE/RAID fileservers mirrored in real time using MountainViewData MVDsync Software (

05/18/03Maurizio Davini Hepix2003 Central Computing Services Simulation and analysis Clusters: 90 AMD Athlon MP cpus running RedHat 7.3 and openMosix 16 Intel Xeon connected with Myrinet Network installed with NPACI Rocks Intel PIII running RedHat 7.3 and openMosix 6 AMD Athon MP cpus running ClusterFrame 1.5 ( Qlusters Inc. )

05/18/03Maurizio Davini Hepix2003 Central Computing Services Installation systems for Linux machines and clusters: 1. Kickstart 2. SystemImager 3. Rocks 4. Oscar (test) 5. MVD PowerCockpit 2 ( in test)

05/18/03Maurizio Davini Hepix2003 Central Computing Services Monitoring of Services made with Big Brother software Monitoring of Clusters made with Ganglia Monitoring Software

05/18/03Maurizio Davini Hepix2003 Cluster and Storage Lab The ClusterLab is dedicated to test new technologies in Clusters (new hardware, new storage technologies,new interconnects) We receive help from AMD Italy for this work

05/18/03Maurizio Davini Hepix2003 Cluster and Storage Lab We have Linux Networx Evolocity Cluster with 10 AMD Athlon MP SuperMicro Intel Xeon machines connected by Dolphin Interconnects and Scali Software 2 Newisys S120 Dual Opteron systems A SAN made with Vixel 335 FiberChannel switches and IDE2FC Raid Array An Infiniband switch and 2 adapter (Mellanox) on order

05/18/03Maurizio Davini Hepix2003 Network All the Department network has been redesigned together with INFN Pisa and is now based on Extreme Networks and Juniper Networks Hardware The Backbone is Gb ethernet In the rooms we have now 100Mb ethernet

05/18/03Maurizio Davini Hepix2003 The Future We are introducing AMD Opteron platform for central services and cluster computing At the moment we are trying Newisys S120 machines for central services and Appro HyperBlade for clusters
