VMmark 2.1 has been released and is available here. We had a list of improvements to VMmark 2.0 even as we finished up the initial release of the benchmark last fall. Most of the changes are intended to improve usability, managability, and scale-out-ability of the benchmark. VMmark 2.0 has already generated tremendous interest from our partners and Read more...

Experimenting with Cluster Scale-Out Utilizing VMmark 2

posted

The first article in our VMmark 2 series gave an in-depth introduction to the benchmark while also presenting results on the scaling performance of a cluster based on a matched pair of systems.  The goal of this article is to continue to characterize larger and more diverse cloud configurations by testing scale-out performance of an Read more...

Cisco Publishes First VMmark 2.0 Result

posted

Our partners at Cisco recently published the first official VMmark 2.0 result using a matched pair of UCS B200 M2 systems. You can find all of the details at the VMmark 2.0 Results Page. Using a matched pair of systems provides a close analogue to single-system benchmarks like VMmark 1.x while providing a more realistic Read more...

Performance Scaling of an Entry-Level Cluster

posted

Performance benchmarking is often conducted on top-of-the-line hardware, including hosts that typically have a large number of cores, maximum memory, and the fastest disks available. Hardware of this caliber is not always accessible to small or medium-sized businesses with modest IT budgets. As part of our ongoing investigation of different ways to benchmark the cloud Read more...

Two Host Matched-Pair Scaling Utilizing VMmark 2

posted

As mentioned in Bruce’s previous blog, VMmark 2.0 has been released.  With its release we can now begin to benchmark an enterprise-class cloud platform in entirely new and interesting ways.  VMmark 2 is based on a multi-host configuration that includes bursty application and infrastructure workloads to drive load against a cluster.  VMmark 2 allows for Read more...

VMmark 2.0 Release

posted

VMmark 2.0, VMware’s next-generation multi-host virtualization benchmark, is now generally available here. We were motivated to create VMmark 2.0 by the revolutionary advancements in virtualization since VMmark 1.0 was conceived. The rapid pace of innovation in both the hypervisor and the hardware has quickly transformed datacenters by enabling easier virtualization of heavy and bursty workloads Read more...

VMmark 2.0 Beta Overview

posted

As I mentioned in my last blog, we have been developing VMmark 2.0, a next-generation multi-host virtualization benchmark that models not only application performance in a virtualized environment but also the effects of common virtual infrastructure operations. This is a natural progression from single-host virtualization benchmarks like VMmark 1.x and SPECvirt_sc2010. Benchmarks measuring single-host performance, while valuable, Read more...
