Desktop Services

500 desktop PCs running:

Windows (XP/2000) ~40% Linux ~40% MacOS (9.x and X) ~20%

05/18/03 Maurizio 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

05/18/03 Maurizio 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

Central Computing Services

All users directories are hosted on IDE/RAID fileservers mirrored in real time using MountainViewData MVDsync Software

Cluster and Storage Lab

The ClusterLab is dedicated to test newtechnologies in Clusters (new hardware, new storagetechnologies,new interconnects)

We receive help from AMD Italy for this work

05/18/03 Maurizio Davini Hepix2003

Cluster and Storage Lab

We have Linux Networx Evolocity Cluster with 10 AMD Athlon MP

1900+ 2 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

05/18/03 Maurizio 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

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
