Agenda
Status
- CSCS (reports Pablo):
- Central Storage extension
- PSI (reports Fabio):
- Designing a Fast, HA, SAN 10TB /home based on GPFS with:
- Two servers, like 2u HP Proliant + GPFS 3.5 - Node quorum with tiebreaker disks
- Well tested dual card Qlogic FC 8Gbit/s
- 2u 24-bay IBM DS3524 or 2u 24-bay SGI IS5000.
- 6 Gbps SAS 2.5" 900GB 10k disks, but I'd want to put the GPFS metadata on SSD or 15k in RAID1 ( opinions? )
- Tot 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 several WN panics, we introduced SGE queues memory limits, default is 3GB per Job, users can ask up to 6GB.
- We introduced a recent/all hierarchical SGE accounting file to speed up the
qacct
response times.
- Testing dCache 1.9.12 inside our VMWare testbed.
- UNIBE (reports Gianfranco):
- UNIGE (reports Szymon):
