Description

We have performed several evaluation of new hardware during the last year ranging from the new generation of worker nodes to testing of a deduplication solution. In the talk, we present results from testing of deduplication technology from Fujitsu using synthetic data as well as real life backup and HEP experiment data. It is a common worry that the disk performance can hardly scale with increasing number of cores in the worker nodes. We show the disk performance scaling evaluation using a C6145 Dell server equipped with 64 cores with up to 10 disk drives. We also show HEP-SPEC and performance/watt numbers for new Intel Sandy Bridge processors.
