Remote Flash Services for Blade Servers

With SQL Server 2014, OCZ enables ZD-XL SQL Accelerator 1.5 software to run next to the database application on blade or specific 
rack-mounted servers while the SSD flash is located remotely on either a commodity server or storage appliance.  As a result, ZD-XL 
SQL Accelerator 1.5 software bypasses the storage stack to provide direct connection of its flash cache remotely.

Direct Pass Caching Technology

When SQL Server databases are larger than the available flash resources, ZD-XL SQL Accelerator employs advanced application-
optimized caching policies as part of its proprietary Direct Pass Caching Technology that efficiently selects what data to place in flash 
cache so that the right data is selected for the specific workload.
