windows10iopsforvdi_satinWindows 10 and IOPS is the most challenging, least understood and most frequently encountered resource bottleneck that stalls todays desktop virtualization projects. Many of these projects are Windows 10 migrations which are one of the key IT initiatives which are driving VDI adoption today. However, many IT organizations planning a Windows 10 migration with VDI are unaware that the combination of Windows 10 and antivirus more than doubles the amount of memory and IOPS required per desktop compared to Windows XP and Windows 7, which will significantly decrease virtual desktop density per server and will degrade virtual desktop performance. As a result, the storage architecture is often undersized for Windows 10. This leads to desktop performance, very poor user experience and budgeting issues when more storage is required to fix the IOPS bottleneck and latency challenges.

Why IOPS and Latency are Key

Delivering a good desktop experience, whether it is a physical PC or a virtual desktop, is a matter of ensuring that it has sufficient hardware resources (e.g. GPU, CPU, Memory, Storage) to run the operating system and applications of the desktop. With Physical PCs, the process is simple because each of those resources is both local to the PC and dedicated for that PC. In desktop virtualization, we are abstracting and pooling those hardware resources. With memory and CPU, the pool of resources is limited to the hypervisor and the hence the physical server, which remains local to the desktop and is easily predictable and handled well by a variety of memory and CPU optimization techniques. However, with desktop virtualization, the hard drive is moved to shared storage, this storage is then shared between hypervisors, allowing consequences to spread across the whole infrastructure. In order to deliver a consistently high performance virtual desktop experience that is equal or better than a physical PC, virtual desktops require constant access to low latency and high throughput storage.
There are three challenges with VDI: Cost, Performance and Complexity. Storage selection, whether you are choosing storage with high performance or high capacity will have a significant impact on cost, performance and complexity.
