HP now is offering systems equipped with these processors in its HP ProLiant DL585 G5 servers, Red Hat said.Rapid Virtualization Indexing improves the efficiency of virtual guest operating systems’ memory management, Red Hat said. Red Hat also is offering para-virtualized device drivers to make IO workloads in virtual guests perform close to the bare-metal performance of the system, said Doug Shakshober, senior consulting engineer at Red Hat. In OLTP testing, Red Hat Enterprise Linux showed that a virtualized guest using Rapid Virtualization Indexing and the para-virtualized drivers had a 21-fold performance gain and reached 77 percent of the performance of a non-virtualized environment using a 16-CPU virtualized guest on a difficult database OLTP workload, the company said. Red Hat Enterprise Linux 5.1 has been shipping since November. Technology Industry
