The Flash Virtualization System is a new kind of solution for storage IO optimization for virtualized computing. The solution combines host-level software with a flash-provisioned server to improve storage IO performance for large numbers of virtual machines (VM) across a VMware vSphere cluster. The solution is deployed as a complement to organizations’ existing virtualization hosts and shared storage infrastructure. Because the solution is non-disruptive to existing storage and servers, is relatively easy to evaluate, validate and deploy, and is cost-competitive versus alternatives, organizations can quickly begin realizing the value of flash acceleration across applications and virtual machines.
The Flash Virtualization System leverages the new architecture in FlashSoft software 4 to take advantage of VMware’s new vSphere APIs for IO Filtering (VAIO) framework, allowing the FlashSoft software to be integrated as a virtual data service within vSphere. This integration with vSphere 6 gives FlashSoft a greater level of reliability, usability and performance; and enables simple, cluster-wide administration. FlashSoft software is certified VMware Ready™, the highest level of VMware certification, assuring the highest level of validation and end user confidence.
Offered in capacities of 12.8TB or 25.6TB, the Flash Virtualization System scales to support acceleration of large numbers of virtual disks per host without increasing CPU or memory requirements. The solution may be deployed singly or in combination in clusters of any size - up to the vSphere 6 maximum of 64 hosts.
Dynamic Cache Allocation
The Flash Virtualization System automatically ensures optimal cache usage per virtual disk, assigning cache space dynamically as new virtual disks are accelerated on the host.
Storage System Enhancement
The majority of IO requests are fulfilled by the flash server rather than primary storage, alleviating much of the burden from—and extending the usable life of— existing storage systems.
Live Cache Assignment
Assign & re-assign caching to virtual disks without VM or host restart.
VMware vCenter™ Web Client
A standard plug-in to vCenter supports management of FlashSoft software functions directly through the vCenter Web GUI.
Increase Application Performance
Delivering intelligent flash-powered application acceleration, read IOPS increased nearly 55 times compared to baseline performance levels on primary storage when 20 virtual machines were tested using a 100% random read performance benchmark1.
Decrease I/O Latency & Increase VM Density
Offering increased productivity and utilization per host server, average read latency was reduced nearly eight times while allowing 10 times more VMs to be operated. Response time improved with 10x more VMs!2.
