STEC Releases EnhanceIO SSD Cache Software for Linux and Windows
STEC has announced the general availability of the its EnhanceIO SSD Cache Software for Linux and Windows. An open-source Linux version of EnhanceIO SSD Cache based on Facebook's Flashcache module will also be made available under a general public license (GPLv2).
EnhanceIO SSD Cache Software is designed to use any SAS, Fibre Channel, PCIe or SATA SSD as a cache device. SSD caching extends the useful life existing SANs by offloading read I/O to the SSD cache while the SAN processes other I/O activity. The software also minimizes server memory utilization when storing cache metadata, reducing the impact of the caching software on server resources.
EnhanceIO SSD Cache Key Features
- Hardware Independence: EnhanceIO is independent of hardware and accelerates any host disk volume.
- Platform Independence: EnhanceIO has been designed for both Windows Server and Linux Server environments.
- Block Level Acceleration: EnhanceIO accelerates I/O blocks that have been cached in the SSD.
- Versatility: EnhanceIO can accelerate multiple HDDs and/or volumes that are being accessed by the host upon which it is installed.
- Metadata Storage: Metadata for the cache is stored in system DRAM rather than in an SSD for fast cache page mapping.
- Cache Block Size: EnhanceIO supports a block size of 2K, 4K (default), or 8K bytes.
- Performance Profiler: EnhanceIO's Performance Profiler can monitor an application's workload and guide the administrator to an economical configuration with accelerated I/O performance.
EnhanceIO SSD Cache Software starts at $295 for Linux and $495 for Windows, per server installation for a one-year subscription. The software is now available for download.
