Earlier we have been discussing the VDI use cases of the three different series of Dell EqualLogic hybrid storage arrays we offer.

As you recall, EqualLogic PS-M4110XS series hybrid arrays provide a blade form factor suitable for a comprehensive, self-contained VDI solution within a modular and compact blade enclosure. Together with Dell PowerEdge blade servers and Dell Force10 blade switches, these hybrid blade arrays create a “data center in a box” for VDI deployments.

This approach helps organizations reduce virtual desktop deployment and operational costs through efficient use of switching resources, minimized cabling, and consolidated management.

Recently we created a Reference Architecture that presents this unified compute, storage, and switching all-in-blade-form-factor platform for hosting and running VDI workloads.

This Reference Architecture demonstrates how a modular 1,000 standard user virtual desktop environment – all self-contained within a Dell PowerEdge M1000e blade chassis – can be deployed in a VMware Horizon View 5.2 VDI infrastructure leveraging 12 PowerEdge M620 blade servers, four Force10 MXL blade switches, and two EqualLogic PS-M4110XS hybrid blade arrays.

In the test environment, two PS-M4110XS arrays delivered approximately 19,000 IOPS during boot storm, 9,000 IOPS during login storm, and 4,400 IOPS during steady state with satisfactory performance results across all layers – user layer, hypervisor layer, and storage layer – of the stack.

This paper provides the details of the storage I/O characteristics under various VDI workload scenarios like boot and login storms along with performance characteristics throughout the VDI stack (for example, ESXi server performance and user experience).
