Low-Latency Systems through Flash-Based Caching
FlashSoft's innovative caching technology applies enterprise flash to accelerate I/O. FlashSoft software uses flash storage installed in the server to minimize latency and reduce I/O between server and storage. With FlashSoft software, the most frequently accessed data is cached on high-performance flash in the server, accelerating I/O without requiring modifications to storage infrastructure.
FlashSoft software works with any standard SSD attached via SATA, SAS, or PCIe. The software also supports any SAN or DAS storage infrastructure.
Simple Deployment and Transparent Operation
The software installs in a few minutes and runs transparently as a kernel module within the Linux operating system. FlashSoft software is directed to the SSD that it will use as a cache, and the administrator identifies the volumes to be accelerated. FlashSoft automatically identifies the hot data and begins accelerating the applications.
Minimal System Overhead
FlashSoft for Linux requires minimal server resources--typically just 3 to 5 percent of CPU capacity and 140MB of RAM. FlashSoft delivers all the benefits of SSD performance with minimal impact on server resources.
Read-and-Write Caching or Read-Only Caching
FlashSoft provides a read-write cache for optimal performance with workloads such as databases and transactional applications. FlashSoft can also be deployed as a read-only cache for read-intensive workloads such as web servers, data analytics, and streaming media.
Cache Persistence & Recovery
The software's cache data and metadata reside entirely on the SSD for persistence in the event of a server crash or system failure. The unique metadata model enables full recovery of the cache in fractions of a second upon system restart.
Data Coherence & Integrity
FlashSoft supports deployment of multiple SSDs in RAID configurations. The software also offers intelligent tools for data protection and recovery to protect against data loss in the event of SSD failure.
