Accelerate Disk (XD) uses the Nytro™ WarpDrive technology to enhance performance for those applications that are primarily stored on spinning HDD media. Nytro XD accelerates the performance of applications that use either Storage Area Network (SAN) attached or Direct Attached Storage (DAS) by identifying the frequently accessed data. This data is copied into low-latency Flash storage located on the Nytro WarpDrive. Nytro XD improves the I/O performance to meet the requirements of the high-performance applications. Nytro XD uses the high-performance Nytro WarpDrive card as a secondary tier of cache to provide faster read and write access to maximize the transactional I/O performance of the application. When the contents of the cache is updated by a write I/O, the contents of the back-end storage is also updated (write through). Nytro XD is designed to accelerate the I/O performance of the applications that are limited by the HDD performance by only requiring a small investment in the Nytro Flash technology-based solutions.
