BayStor from Bay Storage Technology (Bay Storage Technology ) is an innovative, software-enabled technology for deploying network attached DRAM and tiered storage on x86 commodity servers.   Over the last year or so, SAP has been working with Bay Storage Technology to evaluate BayStor's ability to improve I/O latency and bandwidth for SAP's IQ columnar database.  We have seen excellent results in our validation tests to date.  Since IQ uses a shared main database and shared temporary storage, many customers have expressed a wish to avoid continued purchases of large shared storage systems from traditional storage vendors due to their enormous cost. BayStor is an attractive solution as it is cost-effective, while providing a network attached shared storage solution with the performance of locally attached storage.  BayStor can be used for network attachment of any storage devices with or without DRAM caching. Since BayStor is seen by Linux systems as a standard block device, I/O intensive applications are accelerated without modification.
