The software provides a new integrated approach for making application-optimized data cache selections while minimizing I/O access times to SSD flash. It achieves this type of dynamic cache selection optimization by splitting the caching policy engine between the core mechanism running in the Linux kernel and a statistical out-of-band analysis module that optimally determines which data needs to be placed in the cache and stores the data locally in OCZ enterprise-SSDs.
The LXL software supports a wide range of OCZ enterprise solid state solutions across multiple interfaces (i.e. Z-Drive R4 PCIe Series, the Talos 2 SAS Series and the Deneva 2 SATA Series).
"By enabling intelligent direct pass caching, all data requests to and from the SAN are streamlined, reducing external traffic by up to 90 percent, as out-of-band communication with the data path provides very high selection efficiencies and ultra-low latency," said Dr. Allon Cohen, Vice President of Software and Solutions for OCZ Technology. "This innovative LXL architecture avoids the data-path processing penalties typically associated with selectively caching data and enables tighter integration of the data path from application to SSD flash. This beta program will allow OCZ to work closely with our partners to demonstrate and explore the benefits that this software delivers when paired with our SSD hardware to form a total solution for Linux-based environments."
OCZ is offering the beta version of the new caching software to its enterprise SSD customers for testing, under an NDA.
OCZ plans general availability of LXL Software in the early Q2 2013 timeframe.
