Most organizations have either considered or implemented some degree of desktop virtualization. Whether the reasons are tied to endpoint expense, endpoint manageability, support for a mobile workforce, or some combination of those and other factors, one of the key considerations in the design process is the ability for centralized storage to support the I/O patterns that come along with having a high concentration of workstations running in a virtual environment.
The user experience in virtual desktop implementations (VDI) is in many ways directly tied to storage performance. The workload on the storage system can increase dramatically at times of days when large numbers of users concurrently start virtual workstations. Periodic virus scanning software or updates can also generate spikes of disk activity that are significant when they happen concurrently for large numbers of users accessing shared storage.
Nimble Storage arrays, built on Nimble’s Cache Accelerated Sequential Layout (CASL) architecture, are designed to provide performance that adapts to those demanding I/O patterns and to deliver a positive user experience. CASL consists of a combination of flash for read cache and write optimized storage layout. This enables Nimble Storage platforms to provide extremely high performance and to adapt to the changing I/O patterns required in virtualized environments.
Nimble Storage also provides efficiency with respect to the cost of desktop virtualization by compressing data as it is being stored, reducing required space by as much as fifty percent without a negative impact on performance. The combination of VMware View Linked Clones and Nimble Storage zero-copy clones also allows system administrators to set up virtual desktops without requiring full copies for each system, even further increasing storage efficiency.
