Also on Monday, STEC is releasing an update to its EnhanceIO SSD Cache Software, which uses algorithms to identify the most-needed data for an application and caches it on flash. STEC has extended EnhanceIO's support for Windows server OSes to Windows 2012 and has added a "write-back" caching mode in which some data is written only to the SSD. The company has also made EnhanceIO work with the Hyper-V and Xen hypervisors in addition to VMware.
EnhanceIO works with hardware from multiple vendors and comes with management software to help IT managers set up new flash caches. The software can be integrated into the platforms that system manufacturers build with STEC flash.
The s840 SAS SSD and s1120 PCIe Accelerator SSD will cost $7,995 and $9,425, respectively. The EnhanceIO SSD Cache Software is sold on an annual license for each physical or virtual server. It costs $295 for Linux servers and $495 for Windows servers. The update announced Monday will be available immediately, free to current license holders.
