> This document provides information about using the LSI® Nytro™ XD Application Acceleration Storage Solution (hereafter referred to as the Nytro XD solution throughout the document) in a Linux server environment. For operation in a Windows server environment, refer to the LSI Nytro XD Application Acceleration Storage Solution Windows User Guide. The Nytro XD solution uses the Nytro™ WarpDrive technology to enhance performance for those applications whose data are primarily stored on spinning HDD media.

> The Nytro XD solution 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 (cache device) card. The Nytro XD solution improves the I/O performance to meet the requirements of the high-performance applications in data centers. The Nytro XD solution uses the high-performance Nytro WarpDrive card as a cache to provide faster read and write access to maximize the transactional I/O performance of the application. When the content of the cache is updated by a write I/O, the content of the back-end storage is also updated (Write Through).

> The Nytro XD solution is designed to accelerate the I/O performance of the applications that are limited by the HDD performance by only requiring relatively a small investment in the Nytro Flash technology-based solutions. The following figure shows the caching operation by the Nytro XD solution.
