vMotion across hybrid cloud: performance and best practices

posted

VMware Cloud on AWS is a hybrid cloud service that runs the VMware software-defined data center (SDDC) stack in the Amazon Web Services (AWS) public cloud. The service automatically provisions and deploys a vSphere environment on a bare-metal AWS infrastructure, and lets you run your applications in a hybrid IT environment across your on-premises data Read more...

vSAN Performance Diagnostics Now Shows “Specific Issues and Recommendations” for HCIBench

posted

By Amitabha Banerjee and Abhishek Srivastava The vSAN Performance Diagnostics feature, which helps customers to optimize their benchmarks or their vSAN configurations to achieve the best possible performance, was first introduced in vSphere 6.5 U1. vSAN Performance Diagnostics is a “cloud connected” feature and requires participation in the VMware Customer Experience Improvement Program (CEIP). Performance metrics Read more...

Storage DRS Performance Improvements in vSphere 6.7

posted

Virtual machine (VM) provisioning operations such as create, clone, and relocate involve the placement of storage resources. Storage DRS (sometimes seen as “SDRS”) is the resource management component in vSphere responsible for optimal storage placement and load balancing recommendations in the datastore cluster. A key contributor to VM provisioning times in Storage DRS-enabled environments is the Read more...

SPBM compliance check just got faster in vSphere 6.7 U1!

posted

vSphere 6.7 U1 includes several enhancements in Storage Policy-Based Management (SPBM) to significantly reduce CPU use and generate a much faster response time for compliance checking operations. SPBM is a framework that allows vSphere users to translate their workload’s storage requirements into rules called storage policies. Users can apply storage policies to virtual machines (VMs) Read more...

DRS Enhancements in vSphere 6.7

posted

A new paper describes the DRS enhancements in vSphere 6.7, which include new initial placement, host maintenance mode enhancements, DRS support for non-volatile memory (NVM), and enhanced resource pool reservations. A summary of the improvements follows: DRS in vSphere 6.7 can now take advantage of the much faster placement and more accurate recommendations for all Read more...

We in VMware’s Performance team create and maintain various tools to help troubleshoot customer issues—of these, there is a new one that allows us to more quickly determine storage problems from vast log data using artificial intelligence. What used to take us days, now takes seconds. PerfPsychic analyzes storage system performance and finds performance bottlenecks Read more...

Big Data performance on VMware Cloud on AWS: Spark machine learning and IoT analytics performance on-premises and in the cloud

posted

We did some work comparing Spark machine learning performance on an 8-server on-premises cluster vs. a similarly configured VMware Cloud on AWS cluster. Here is what the VMware Cloud on AWS cluster looked like: Three standard analytic programs from the Spark machine learning library (MLlib), K-means clustering, Logistic Regression classification, and Random Forest decision trees, Read more...

Persistent Memory Performance in vSphere 6.7

posted

We published a paper that shows how VMware is helping advance PMEM technology by driving the virtualization enhancements in vSphere 6.7. The paper gives a detailed performance analysis of using PMEM technology on vSphere using various workloads and scenarios. These are the key points that we cover in this white paper: We explain how PMEM Read more...
