VMware: Performance Evaluation of VMXNET3 Virtual Network Device


VMware published a new paper about the performance evaluation of VMXNET3 virtual network device.

This paper compares the networking performance of VMXNET3 to that of enhanced VMXNET2 (the previous generation of high performance virtual network device) on VMware vSphere 4 to help users understand the performance benefits of migrating to this next‐generation device.

VMware: VMFS Best Practices

The VMware Virtual Machine File System (VMFS) is a high performance cluster file system that allows virtualization to scale beyond the boundaries of a single system. Designed, constructed, and optimized for the virtual server environment, VMFS increases resource utilization by providing multiple virtual machines with shared access to a consolidated pool of clustered storage. And VMFS provides the foundation for virtualization spanning multiple servers, enabling services such as VMware VmotionTM, Distributed Resource Scheduler, and VMware High Availability.
VMFS also reduces management overhead by providing a highly effective virtualization management layer, one that is especially suitable for large-scale enterprise data centers. Administrators employing VMFS find it easy and straightforward to benefit from the greater efficiency and increased storage utilization offered by the use of shared resources.
This paper gives a technology overview of VMFS, including a discussion of features and their benefits. The paper highlights how VMFS capabilities enable greater scalability and decreased management overhead. It also provides best practices and architectural considerations for deployment of VMFS.

VMware: VUM Perfomance Whitepaper

VMware Update Manager (VUM) provides a patch management framework for VMware Virtual Infrastructure. IT administrators can use it to patch VMware ESX, Windows, and certain versions of Linux virtual machines.  As data centers get bigger, performance implications become more important for patch management. This study covers the following topics:

  • Benchmarking Methodology
  • VUM Server Host Deployment
  • Latency Overview
  • Resource Consumption Matrix
  • Guest Operating System Tuning
  • Network Latencies
  • On-Access Virus Scanning
