This Dell EMC Ready Stack includes Dell EMC’s latest enterprise-level rack servers, LAN and SAN switches, storage arrays, and state-of-the-art management software. These Ready Stack components have been carefully selected and tested to provide outstanding performance and value.
This Ready Stack design offers flexibility to address various virtualization use cases and workloads, including the increasing demands that come from unstructured data. Sizing a physical infrastructure for all virtualized workloads in a specific environment requires knowledge of all the individual workloads and related compute, memory, storage, and network performance requirements. After you have created one or more VM profiles that meet your requirements, you can approximate the physical infrastructure that is required to support VMs while also accounting for expected future growth. When finalizing sizing, ensure that you also consider server and storage maintenance requirements and virtualization features such as high availability. Conduct a site survey in cases where an approximation is not sufficient.
This Ready Stack provides a description of a typical implementation. For information about applying the resources and methodologies that are described in this guide to a smaller- or larger-scale implementation, consult your Dell EMC Sales team.
For the purposes of this document, we have proposed a sample configuration that is based on the following balanced VM profile for a single VM:
2 vCPUs, 6 GB vRAM, 60 GB vDisk, 50 IOPS
For example, when scaled to a configuration of 500 VMs, the resource totals are:
1,000 vCPUs, 3 TB vRAM, 30 TB vDisk, 25,000 IOPS
We based our configuration sizing on a vCPU-to-CPU oversubscription of 4:1. The configuration provides the physical infrastructure resources that are necessary to accommodate the total number of VMs while providing ample headroom for growth.
