As an update to a previous posting, HP has just published a whitepaper highlighting dramatic TPS performance and VM density using HP IO Accelerators and Fusion’s ioTurbine caching software with virtualized HP DL980 servers.
Benchmark testing demonstrated a 2.8x increase in performance achieved by adding just two 1.28TB IO Accelerators and ioTurbine software to a pair of HP ProLiant DL980 servers running Microsoft Windows 2008 and VMware ESX 4.1, connecting with HP P4800 storage. The configuration supports an aggregated 7120 transactions-per-second (TPS) across 16 VMs running SQL workloads, in parallel. This result compares to 2521 TPS for the same baseline but uncached configuration.
The testing illustrates that this solution not only adds scale to the HP DL980 server but also dramatically increases VM densities to support almost any application, regardless of workload, in a virtual server environment. Having more and larger size VMs makes more efficient use of infrastructure, lowers costs and provides the opportunity to run databases in a virtualized environment, something that was previously not possible or cost prohibitive, at least until now. The solution is an ideal VMware consolidation platform and preserves VMware vMotion and high availability capabilities, important customer requirements.
Of course, this same solution approach can also be attractive for customers interested in using HP IO Accelerators and ioTurbine with other HP servers such as the HP DL580, HP DL380 and the BL460 for bladed environments.
Note also that testing was accomplished with HP’s Gen1 IO Accelerators, so performance results would be expected to be even better using HP’s recently announced ioDrive2 IO Accelerators.
