FlashSoft software for Windows Server enables IT managers to cost-effectively boost database and application performance on Windows Server 2012, 2008 and Windows Server Hyper-V 2012 R2 while simultaneously reducing the IOPS load on the storage infrastructure. FlashSoft enables a solid-state device (SSD) to function as a cache for frequently accessed data in a server. FlashSoft software is installed as a filter driver within the Windows driver stack. By caching the hot data on a high-speed SSD installed on the server, access times are reduced and applications spend less time waiting for data.
FlashSoft for Windows Server accelerates enterprise applications, such as Microsoft SQL Server®, MySQL®, Microsoft Exchange and Microsoft SharePoint®.

Accelerate Windows Server Hyper-V Clusters1
FlashSoft software for Windows Server targets Cluster Shared Volumes (CSV). Hyper-V virtual machines hosted on CSV can be accelerated with FlashSoft — with full support for Hyper-V cluster features like LiveMigraton and Failover. FlashSoft supports the use of CSVs when the cache is used in write-through mode. FlashSoft installs as a base Windows Server driver, not inside virtual machines, making it efficient to run and simple to install and manage.
Support for Large Datasets
FlashSoft supports up to 16TB of flash as cache, and up to 4 caches per server, allowing users to accelerate extremely large datasets. Large datasets often are deployed across multiple storage volumes. FlashSoft supports up to 2048 accelerated volumes.
Simple Deployment & Transparent Operation
The software installs in a few minutes and runs transparently. Manage from a familiar Windows GUI or using PowerShell. FlashSoft software automatically identifies the hot data and begins accelerating applications.
File-level Policy-based Caching for Maximum Caching Efficiency
With FlashSoft an administrator can set a policy to exclude certain files on an accelerated volume for the cache. Especially useful in Hyper-V environments, this policy can deliver the maximum benefits of caching without modifying VM configurations.
Minimal System Overhead
FlashSoft for Windows Server requires minimal server resources — typically just 3 to 5 percent of CPU capacity and under 500MB of RAM.
SanDisk conducted a synthetic performance test2 on a dual processor Dell PowerEdgeTM server with 128GB RAM. Two Optimus AscendTM (SAS) SSDs were configured as a 30GB RAID1 (mirrored) write-back cache to accelerate a 100GB HDD storage back end. The benchmark program fio.exe was used to generate a workload and measure performance.
Performance tests illustrate FlashSoft software was able to accelerate the workload from 450 IOPS to 6,462 IOPS – over 14x increase in performance compared to the non-accelerated back end. Storage latency was also greatly improved dropping from 1,272 milliseconds to 55.65 milliseconds – over 22x improvement in response time.
