This document details the architecture design, configuration, and implementation considerations when deploying a VDI workload with 3,600 VMware Horizon virtual desktops on the Dell EMC PowerStore 9000T model storage array. This document is primarily storage-focused and details the specific configurations of this system. Also, the network and fabrics that are used for connectivity is explored in detail.
PowerStore layers protocols and services on a flexible, container-based architecture, ensuring that features and services can be added to existing installations with minimal impact. This paper discusses the benefits of a unified storage product that combines block and file services into a virtual desktop infrastructure (VDI) platform. PowerStore allows expansion of both functionality and capacity to protect storage investments.
The information in this document is based on the guidelines in Dell EMC PowerStore: VMware vSphere Best Practices. This document includes supplemental information regarding VDI-specific details when running VMware Horizon.
As part of this reference architecture, the solution was tested using the industry-standard Login VSI VDI benchmarking tool. The PowerStore 9000T model appliance delivered sub-millisecond latency to 3,600 virtual desktops running a heavy workload of 30 IOPS per user. This would meet the performance requirements of most organizations.
