Check list for HW deployment on Q1 2008
The aquisition of 34 mid-range servers and 60 storage arrays will replace RAC1 (named RAC5, names to be ITRAC5xx, ITSTOR5xx) and create a new RAC6 (named ITRAC6xx, ITSTOR6xx, racks EK03-EK11).
Networking
- Contacts: Marc Collignon, David Parra-Arroyo, Eric Sallaz
- Current state (2008.01.10): Installed on RAC6. HW ready for RAC5
- Needs:
- need for RAC1+RAC6:
- 2+2 switches for private network with possible uplink
- 2+2 switches for public network (48 port each)
- 1+1 switches for console management
- 1+1 IP-Service
- 60+60 IP addresses (20 publicIP + 20 virtualIP + 20 backups)
Console
- Andras Horvath, console.support
- Current state (2008.01.10): Installed LXC1EK13 on RAC6. Available for RAC5.
- Needs:
- 1+1 headnode (2 headnodes of RAC1 will stay, one new for RAC6)
- mid-range servers will use IMPI (over LAN, no headnode needed)
- RAC1 headnodes out of warranty, Andras prefer to replace only in case of failure, they have them in stock
HW installation
- Tim Whibley
- Current state (2008.01.10): rails with 4weeks delay, should arrive 5W2008;storage should arrive soon; servers expected 5W2008. Tim and Sam to coordinate installation. Removal of RAC1 after 23rd January
- Needs:
- 30+30 storage arrays
- 17+17 mid-range servers (2U)
- Rails
As only 76 out of 230 pairs will be received, Helge ordered 17 Dell rails for RAC6.
Delivery due in two weeks.
Moreover, we requested 8 rails pairs for RAC5
so that we could set-up the two ATLAS clusters (Helge will
inform you about the final decision).
If all goes ok we could have all RAC6 ready and a part of RAC5, with the
following LHC experiments production RACs:
- CMS, LHCb, WLCG and the downstream capture boxes on RAC6 (Dell rails)
- ATLAS offline and online on RAC5 (8 pairs from the current batch)
and be ready for CCRC'08 by April 14th, with a very tight schedule.
Fiber channel
- Contacts: Andras Horvath, Tim Whibley
- Current state (2008.01.10): RAC6 installed. RAC5 - hw and cables already at CERN, ready to install
- Needs:
- 8+8 QLogic SANBox5600 (with SFPs)
- FC cables
