Using VMmark 3 as a Performance Analysis Tool

posted

VMmark was originally developed to fill the need for a server consolidation benchmark for a rapidly changing datacenter that was becoming increasingly dominated by virtualization.  The design of VMmark, which is a collection of workloads, gives us the ability to quickly change workload parameters to modify the behavior of the entire benchmark. This allows us Read more...

vSphere 6.7 Update 3 Supports AMD EPYC™ Generation 2 Processors, VMmark Showcases Its Leadership Performance

posted

Two leadership VMmark benchmark results have been published with AMD EPYC™ Generation 2 processors running VMware vSphere 6.7 Update 3 on a two-node two-socket cluster and a four-node cluster. VMware worked closely with AMD to enable support for AMD EPYC™ Generation 2 in the VMware vSphere 6.7 U3 release. The VMmark benchmark is a free tool used by hardware vendors and others to measure Read more...

Addressing Meltdown/Spectre in VMmark

posted

The recently described Meltdown/Spectre vulnerabilities have implications throughout the tech industry, and the VMmark virtualization benchmark is no exception. In deciding how to approach the issue, the VMmark team’s goal was to address the impact of the these vulnerabilities while maintaining the value and integrity of the benchmark. Applying the full set of currently available Read more...

Power Management and Performance in ESXi 5.1

posted

Powering and cooling are a substantial portion of datacenter costs. Ideally, we could minimize these costs by optimizing the datacenter’s energy consumption without impacting performance. The Host Power Management feature, which has been enabled by default since ESXi 5.0, allows hosts to reduce power consumption while boosting energy efficiency by putting processors into a low-power Read more...

Exploring Generational Differences in Performance and Energy Efficiency Using VMware VMmark 2.5

posted

Each new generation of servers brings advances in hardware components. For IT professionals purchasing or managing new generations of hardware, it’s vital to understand how these incremental hardware improvements translate into real-world gains in the datacenter. Using the VMware VMmark 2.5 virtualization benchmark, we compared performance and energy efficiency of two different generations of servers Read more...

Exploring FAST Cache Performance Using VMmark 2.1.1

posted

A system’s performance is often limited by the access time of its hard disk drive (HDD). Solid-state drives (SSDs), also known as Enterprise Flash Drives (EFDs), tout a superior performance profile to HDDs. In our previous comparison of EFD and HDD technologies using VMmark 2.1, we showed that EFD reads were on average four times Read more...

Comparing ESXi 4.1 and ESXi 5.0 Scaling Performance

posted

In previous articles on VROOM! we used VMmark 2 to investigate the effects of altering a single hardware component, such as a storage array or server model, in a vSphere cluster. In contrast to these earlier studies, we now examine the effects of upgrading the hosts’ software from ESXi 4.1 to ESXi 5.0 on the Read more...
