The DCS lab .Computer infrastructure

Peter Chochula

P. Chochula DCS Workshop, CERN , September 2004 2

• This talk covers only the computing part of the DCS lab

• Infrastructure has been partly described in the computing related talk presented at this workshop

Computer hardware

• A number of standard desktop PCs is installed in the lab

• Core computers are rack-mounted machines• DCS server

– 1U system based on INTEL SE7501VW2– Dual Xeon, 2.8 GHz– 3 GB RAM– 0.25 TB of disk space available on UATA RAID– 2xPCI riser card (64 bit!)

P. Chochula DCS Workshop, CERN , September 2004 4

• Worker nodes– 2U computers based on Intel D865GBFLK – Chieftec chassis– 3 slot 32 bit PCI riser cards ( e.g for Kvaser card)– PIV 3.06 GHz, 1 GB RAM– 160 GB disk space on SATA disk

• The computers were tested for thermal stability and are performing well

• Chenbro chassis (with SATA front bays will be evaluated soon)

DCS network

• A dedicated network is installed in the lab• Computers connected to this network are

accessible from CERN• Gateway computer is running the Windows 2003

server• DCS network is used for software evaluation and

tests. Some of these tools could not be run on CERN campus network– Packet sniffers– Traffic generators– Security analyser

P. Chochula DCS Workshop, CERN , September 2004 8

• Users are welcome to use our infrastructure• Ethernet hubs and repeaters are available• One DHCP UTP slot is available• Dedicated network can be used for testing your

hardware (e.g. SDD AREMpro controllers etc.)– device can be quickly registered with the network– No risk of interference with computers connected to

campus network

What is happening in the lab now?

• Presently we are performing ORACLE performance tests for FED configuration

• Influence of network load on PVSS systems will be studied in next weeks (mentioned in Wayne’s talks as “stressing the PVSS network”)

• Remote access via Terminal Server is available• We purchased licenses of Windows 2003 server,

present systems will be re-installed

Services provided in the DCS lab

• After the re-installation of new servers we plan to run following services:

• Windows Server 2003 – production version– Domain controller

– SUS, RIS, DNS,

– Remote Access to lab infrastructure

A clone of this server will be used in pre-installationl

• Windows Server 2003 – development version to be used for software testing

• ORACLE production server – to host you configuration databases and PVSS archive

• ORACLE test server – used for software developments
