Performance of VMware vCenter Server 6.7 in Remote Offices and Branch Offices

The VMware Performance team has published an updated paper detailing vCenter Server 6.7 performance in a remote offices and branch offices (ROBO) environment.

Many organizations today have a ROBO environment with local IT infrastructure. These remote locations usually have anywhere from a few servers running a few workloads to support local needs, to numerous servers spanning a large-scale datacenter. The distributed and remote nature of this infrastructure makes it hard to manage, difficult to protect, and costly to maintain. Further, the remote nature of servers makes it more challenging to perform important VM/host-related operations.

vSphere is designed to address these ROBO use cases, including IT infrastructure located in remote, distributed sites. VMware vCenter Server provides a centralized way to control and monitor the virtual infrastructure, including ESXi hosts, virtual machines, storage, and networking resources. It has been widely deployed in a ROBO environment to manage ESXi hosts that are distributed over large geographical distances over a wide range of networks with different network characteristics, including low/high bandwidth, network latency, and packet error rates. In the paper, we test:

  • LAN with high-bandwidth and low-latency links.
  • WAN with low-bandwidth and high-latency links.
  • Various networks in between; for example, DSL, T1, 4G, 5G, …

We demonstrate that vCenter Server performs well in the ROBO environment for both network bandwidth use, as well as virtual machine and ESXi host task execution times. Instead of a bandwidth restriction, we observe that network latency has a bigger impact on the overall performance. As the network latency between vCenter Server and ESXi hosts increases, the average operation latency also increases. The experimental results also show how efficiently vCenter Server executes VM operations in high-latency networks: The average VM operation execution time increases much more slowly when network latency increases by several times.

What’s New in Performance – VMware vSphere 6.7

Underlying each release of VMware vSphere are many performance and scalability improvements. The vSphere 6.7 platform continues to provide industry-leading performance and features to ensure the successful virtualization and management of your entire software-defined datacenter.

The What’s New in Performance for vSphere 6.7 white paper highlights significant scale and performance items such as:

  • 2x increase in VMware vCenter Server Operations Per Second over the 6.5 release
  • Support for 1GB Large Memory Pages
  • vmxnet3 enhancements to RSS and VXLAN/Geneve Offloads
  • Performant support of new Persistent Memory offerings

As with each release I’m excited about these new capabilities and the performance each of them offers.
