The computing center GridKa is serving the ALICE, ATLAS, CMS and
LHCb experiments as Tier-1 center with compute and storage resources.
It is operated by the Steinbuch Centre for Computing at Karlsruhe Institute
of Technology in Germany. In its current stage of expansion GridKa
offers the HEP experiments a capacity of 35 Petabytes of online storage.
The storage system is based on Spectrum Scale as software-defined-storage
layer. Its storage servers are inter-connected via two redundant
infiniband fabrics and have ethernet uplinks to the GridKa backbone network.
In this presentation we discuss the use of virtualization technologies
in the context of the described storage system, including hardware
virtualization of the infiniband and ethernet interfaces.
