DRS Lens – A new UI dashboard for DRS

This post was originally published on this site
DRS Lens provides an alternative UI for a DRS enabled cluster. It gives a simple, yet powerful interface to monitor the cluster real time and provide useful analyses to the users. The UI is comprised of different dashboards in the form of tabs for each cluster being monitored. Cluster Balance Dashboard showing the variations in the cluster balance metric plotted over time with DRS runs. This shows how DRS reacts to and tries to clear cluster imbalance every time it runs.

Introducing VMmark3: A highly flexible and easily deployed benchmark for vSphere environments

This post was originally published on this site
VMmark 3.0, VMware’s multi-host virtualization benchmark is generally available here.  VMmark3 is a free cluster-level benchmark that measures the performance, scalability, and power of virtualization platforms. VMmark3 leverages much of previous VMmark generations’ technologies and design.  It continues to utilize a unique tile-based heterogeneous workload application design. It also deploys the platform-level workloads found in VMmark2 such as vMotion, Storage vMotion, and Read more [...]

NEW VMworld 2017 Bootcamp – vSphere Advanced Performance Design, Configuration and Troubleshooting

This post was originally published on this site
New this year for VMworld 2017 in Las Vegas, we will be offering a pre-VMworld bootcamp focused on vSphere platform performance. Specific SQL and Oracle bootcamps will still be offered, but we have had many requests for a workload agnostic program. This bootcamp will enable you to confidently support all your virtual workloads and give you an opportunity to directly interact with VMware Performance Engineering. vSphere Advanced Performance Design, Configuration and Troubleshooting The VMware vSphere Read more [...]

Introducing TPCx-HS Version 2 – An Industry Standard Benchmark for Apache Spark and Hadoop clusters deployed on premise or in the cloud

This post was originally published on this site
Since its release on August 2014, the TPCx-HS Hadoop benchmark has helped drive competition in the Big Data marketplace, generating 23 publications spanning 5 Hadoop distributions, 3 hardware vendors, 2 OS distributions and 1 virtualization platform. By all measures, it has proven to be a successful industry standard benchmark for Hadoop systems. However, the Big Data landscape has rapidly changed over the last 30 months. Key technologies have matured while new ones have risen to prominence Read more [...]

Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

This post was originally published on this site
We have just published a new whitepaper on the performance of Oracle databases on vSphere 6.5 monster virtual machines. We took a look at the performance of the largest virtual machines possible on the previous four generations of four-socket Intel-based servers. The results show how performance of these large virtual machines continues to scale with the increases and improvements in server hardware. Oracle Database Monster VM Performance on vSphere 6.5 across 4 generations of Intel-based  four-socket Read more [...]

Capturing the Flag for Cloud IaaS Performance with VMware’s vSphere 6.5 and VIO 3.1 on Dell PowerEdge Servers

This post was originally published on this site
This week SPEC has published a new SPEC CloudTM IaaS 2016 result for a private cloud configuration built using VMware vSphere 6.5 and VMware Integrated OpenStack 3.1 (VIO 3.1) and Dell PowerEdge Servers. Working with VMware, Dell has pushed their lead in cloud performance even further. This time, the primary metric produced was a Scalability score of 78.5 @ 72 Application Instances (468 VMs). The Elasticity score was 87.4%. VMware and Dell are active participants in SPEC and have contributed to the Read more [...]

Weathervane, a benchmarking tool for virtualized infrastructure and the cloud, is now open source.

This post was originally published on this site
Weathervane is a performance benchmarking tool developed at VMware.  It lets you assess the performance of your virtualized or cloud environment by driving a load against a realistic application and capturing relevant performance metrics.  You might use it to compare the performance characteristics of two different environments, or to understand the performance impact of some change in an existing environment. Weathervane is very flexible, allowing you to configure almost every aspect of Read more [...]

DRS Cluster Resource Management with Reservation and Shares

This post was originally published on this site
Resource management in vSphere is very robust and sophisticated. It provides settings like reservation, limits and shares (a.k.a. RLS), which can be applied on virtual machines (VMs) and resource pools. These settings can be used as knobs to isolate resources, prioritize them, or to guarantee availability of resources to VMs in a cluster. Our customers have often asked about how these settings impact availability of resources for a VM. Recently we published a white paper based on our study, to explain Read more [...]
