Skylake Update – Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

Skylake Update – Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

This post was originally published on this site —We were able to get one of the new four-socket Intel Skylake based servers and run some more tests. Specifically we used the Xeon Platinum 8180 processors with 28 cores each. The new data has been added to the Oracle Monster Virtual Machine Performance on VMware vSphere 6.5 whitepaper. Please check out the paper for the full details and context of these updates. The generational testing in the paper now includes a fifth generation with a 112 vCPU virtual machine running on the Skylake based server. Read more […]

Episode 3: Performance Comparison of Native GPU to Virtualized GPU and Scalability of Virtualized GPUs for Machine Learning

Episode 3: Performance Comparison of Native GPU to Virtualized GPU and Scalability of Virtualized GPUs for Machine Learning

This post was originally published on this site —In our third episode of machine learning performance with vSphere 6.x, we look at the virtual GPU vs. the physical GPU. In addition, we extend the performance results of machine learning workloads using VMware DirectPath I/O (passthrough) vs. NVIDIA GRID vGPU that have been partially addressed in previous episodes: Episode 1: Performance Results of Machine Learning with DirectPath I/O and GRID vGPU Episode 2: Machine Learning on vSphere 6 with NVIDIA GPUs Machine Learning with Virtualized GPUs Performance Read more […]

Updated – SQL Server VM Performance with vSphere 6.5, October 2017

Updated – SQL Server VM Performance with vSphere 6.5, October 2017

This post was originally published on this site —Back in March, I published a performance study of SQL Server performance with vSphere 6.5 across multiple processor generations.  Since then, Intel has released a brand-new processor architecture: the Xeon Scalable platform, formerly known as Skylake. Our team was fortunate enough to get early access to a server with these new processors inside – just in time for generating data that we presented to customers at VMworld 2017. Each Xeon Platinum 8180 processor has 28 physical cores (pCores), Read more […]

Performance of Enterprise Web Applications in Docker Containers on VMware vSphere 6.5

Performance of Enterprise Web Applications in Docker Containers on VMware vSphere 6.5

This post was originally published on this site —Docker containers are growing in popularity as a deployment platform for enterprise applications. However, the performance impact of running these applications in Docker containers on virtualized infrastructures is not well understood. A new white paper is available that uses the open source Weathervane performance benchmark to investigate the performance of an enterprise web application running in Docker containers in VMware vSphere 6.5 virtual machines (VMs).  The results show that an enterprise Read more […]

What-If? Resource Management with vSphere DRS

What-If? Resource Management with vSphere DRS

This post was originally published on this site —vSphere Distributed Resource Scheduler (DRS) provides a simple and easy way to manage your cluster resources. DRS works well, out of the box for most vSphere installations. For cases where more flexibility is desired in how the cluster is managed, DRS provides many options in the form of cluster rules, settings and advanced options. Often the impact of using rules in a DRS cluster is not very well understood. The settings and advanced options are not very well documented. Imagine if it was possible Read more […]

Introducing DRS DumpInsight

Introducing DRS DumpInsight

This post was originally published on this site —In an effort to provide a more insightful user experience and to help understand how vSphere DRS works, we recently released a fling: DRS Dump Insight. DRS Dump Insight is a service portal where users can upload drmdump files and it provides a summary of the DRS run, with a breakup of all the possible moves along with the changes in ESX hosts resource consumption before and after DRS run. Users can get answers to questions like: Why did DRS make a certain recommendation? Why is DRS not Read more […]

SPBM Performance Whitepaper

SPBM Performance Whitepaper

This post was originally published on this site —VMware Storage Policy Based Management (SPBM) is a storage policy framework that helps administrators match VM workload requirements against storage capabilities. SPBM runs as an independent service in the vCenter Server. We recently released a white paper [click here to download] that covers SPBM performance in two sections. Performance comparison of vCenter 6.5 v/s vCenter 6.0U3 In the first section, we have covered performance improvements of SPBM in vCenter 6.5 over vCenter 6.0 U3. Here is a Read more […]

New White Paper: Fast Virtualized Hadoop and Spark on All-Flash Disks – Best Practices for Optimizing Virtualized Big Data Applications on VMware vSphere 6.5

New White Paper: Fast Virtualized Hadoop and Spark on All-Flash Disks – Best Practices for Optimizing Virtualized Big Data Applications on VMware vSphere 6.5

This post was originally published on this site —A new white paper is available showing how to best deploy and configure vSphere 6.5 for Big Data applications such as Hadoop and Spark running on a cluster with fast processors, large memory, and all-flash storage (Non-Volatile Memory Express storage and solid state disks). Hardware, software, and vSphere configuration parameters are documented, as well as tuning parameters for the operating system, Hadoop, and Spark. The best practices were tested on a 13-server cluster, with Hadoop installed on Read more […]

DRS Lens – A new UI dashboard for DRS

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.
