Swiss WLCG Operations Meeting on 2012-09-06
Agenda
Status
- CSCS (reports Pablo):
- Central Storage extension
- PSI (reports Fabio):
- Designing a Fast, Highly Available, SAN based 10TB /home based on GPFS using:
- Two 2u HP Proliant + GPFS 3.5 - Node quorum with tiebreaker disks
- Well tested dual card Qlogic FC 8Gbit/s
- 2u 24-bay IBM DS3524 otherwise 2u 24-bay SGI IS5000.
- 6 Gbps SAS 2.5" disks: a reasonable capacity/cost disks choice is 900GB 10k, but I'm waiting offers for SSD and 15k.
- Cost with 10k disks is ~50k CHF.
- BTW, it's still missing features like snapshots but also GlusterFS, now called Red Hat Storage 2.0, can implement a cheap HA /home with 2 NAS.
- Because of WN panics we've enforced SGE queues memory limits, the conf can be interesting for UNIBE.
- Testing dCache 1.9.12 inside our VMWare testbed.
- UNIBE (reports Gianfranco):
