Nytro XD Overview

Nytro XD Overview

This document provides information about the LSI Nytro™ XD Application Acceleration Storage Solution (hereafter referred to as Nytro XD solution throughout the document). Accelerate Disk (XD) uses the Nytro WarpDrive technology to enhance performance for those applications that 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™. The Nytro XD solution improves the I/O performance to meet the requirements of the high-performance applications. The Nytro XD solution uses the high-performance Nytro 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).

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 a small investment in the Nytro Flash technology-based solutions. The following figure shows the caching operation by the Nytro XD solution.
