Computer infrastructure
Peter Chochula
• 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

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

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
