Machine Room Planning
The Machine Room Planning unit in FIO group is responsible for overseeing
| Planning,
installation and safety for the Machine Room in B513 |
|
FIO Group has overall responsibility for the Machine Room in B513
and is thus involved in planning the arrangement of new installations in
the room—something that is becoming more difficult with the large
numbers of PCs being installed for physics computing.
Safety Linkmen have been appointed
by certain groups to ensure that their areas of the machine room are kept
safe and tidy. David
Underhill is the TSO for B513 and Dick
Minchin the TSA for the Machine Room and Vault areas. |
| Upgrading B513
infrastructure to meet LHC computing needs |
|
Based on current plans to meet LHC offline computing
requirements, we will need to make available a false floor area of some
2000m2 by 2003-4 and to support an electrical load of 2MW. In 2000, for comparison, the machine room has a floor area of
1400m2 and the total electrical consumption is 800kW.
A major upgrade is therefore required and this is being planned in close
collaboration with ST division. The key steps in this process are
|
1 |
conversion of the
former Tape Vault in the basement of B513 to a machine room area |
|
2 |
migration of computing equipment to the tape vault |
|
3 |
creation of a new substation to meet the power needs of the
computing and ancillary equipment |
|
4 |
refurbishment of the Machine Room on the ground floor of B513. |

| Construction of a
remote location to house tape robotics —
COMPLETED! |
|
The move to Central Data Recording, together with high capacity tapes (50GB) led to a concentration of Physics Data in
the computer centre, most of it held in four STK silos. This concentration
of data meant that any fire or accident in B513 could have lead to a
catastrophic loss of data.
A remote location to house tape robotics equipment was proposed during
1999 as a way to avoid such a situation, and a project to add a remote
building for tape robots, B613,
as an extension
to B186
was approved in 2000.
Work on the new building started in March 2001 and installation of the STK
silos started on October 1st. A picture record of the
construction work is available.
The end of the project was marked by an article in the Weekly Bulletin:
