Description
The virtual computing is often run to satisfy different needs: reduce
costs, reduce resources, simplify maintenance and the last but not the
least add flexibility.
The use of Virtualization in a complex system such as a farm of PCs that
control the hardware of an experiment (PLC, power supplies ,gas,
magnets..) put as in a condition where not only an High Performance
requirements need to be carefully considered but also a deep analysis of
strategies to achieve a certain level of High Availability.
We conducted a performance evaluation on different and comparable
storage/network/virtulization platforms.
The performance is measured using a series of independent benchmarks ,
testing the speed an the stability of multiple VMs runnng heavy-load
operations on the I/O of virtualized storage and the virtualized network.
The result from the benchmark tests allowed us to study and evaluate how
the different workloads of Vm workloads interact with the
Hardware/Software resource layers.
