The VMS2 is an IEEE P1386.1 compliant PMC module that allows either a 1.8 or 2.5" hard disk drive to be used to build a compact and robust mass storage solution for embedded systems. The VMS2 also facilitates control of a remote IDE storage device (e.g. hard drive).
Ruggedisation options are available to support industrial, airborne and military applications, including industrial temperature operation, conduction cooling and conformal coating. The VMS2 offers various disk mounting factory options. It is possible to use either a standard rotary drive or a solid state drive in either 1.8" or 2.5" form factor.
The bus mastering IDE controller has dual channels, and supports the full range of PIO and UDMA data transfer modes, up to and including ATA/100, allowing users to take full advantage of the latest high speed hard disk drives. As a factory option, an IDE channel may be routed to the PMC Pn4 user I/O connector - for example to allow control of an externally mounted CF card, or a conventional hard drive.
SFF-8038i compliance means the VMS1 is register compatible with standard PCI IDE controllers, and is supported by the standard ATA/IDE device drivers in Windows™, Linux™, VxWorks™ and many other operating systems.
