AN89661 - USB RAID 1 Disk Design Using EZ-USB® FX3S™

Last Updated:

The USB standard allows many peripherals to be connected using a single, standardized interface. Proven over the years as a reliable, expandable, fast, low-cost, low-power, and hot-pluggable interface, USB is now ubiquitous in a wide variety of applications. This application note addresses one such application, a RAID boot disk in servers.
Among server applications, server virtualization is the trend in IT and has become the fastest growing segment of the server market. Server virtualization is the process of using software to partition a physical server into multiple virtual servers. Server virtualization requires a fast, reliable, and compact boot disk that is separated from the main server storage.
The EZ-USB FX3S is a RAID-on-Chip controller with integrated dual Secure Digital (SD) interfaces, which is a perfect fit for a low cost RAID Boot Disk. It not only provides the benefit and function of a SuperSpeed USB mass storage device, but also it manages storage redundancy for high reliability through its RAID-on-Chip functionality.
