Agenda
Status
CSCS:
Update of the recent issues with Lustre and Cream.
ARC Accounting and BDII.
Status of EMI1 upgrade
Migration to GPFS
PSI (reports Fabio):
We're investigating a new 200TB raw storage, several vendors invited to make an offer, so far I've seen these products:
Nexsan 60 SATA disks 4u
NetApp E5400, 60 SATA disks 4u
HP, still unclear what they want to propose
SuperMicro, 45 SATA disks 4u
DataOn, 60 SATA disks 4u
: this one is interesting because can be installed with its
server head
with
OpenIndiana
+
Multipath MPxIO driver
+ dual LSI 9200-8e + ZFS
UNIBE (reports Gianfranco):
Stable operations, ATLAS production and analysis. Also some SMSCG activity
Running stably with CVMFS since a few months now
Had to recover DPM install because of EPEL conflict (operations not affected)
Upgrade to ARC1 postponed due to Lustre bugs
Starting now with KVM
UNIGE (reports Szymon):
Daily operations very stable and quiet, nothing to report.
A major upgrade of storage going ahead:
IBM x3630 M3 with 12 x 3 TB of disk for data + two small disks for the OS
hardware RAID, we will do RAID 6 with cold spares, 27.5 TB net/machine
we are getting 10 machines, only 8 can be powered up soon
to stay in fixed kW budget we will retire 12 login machines, in operation since 2005
most of the new disk servers will be added to our Storage Element
