Vortex VR-6511S8Multi-Channel Data Recorder Many embedded systems designers who develop signal intelligence, Radar, Sonar or image processing applications transfer high-speed digitized data between the sensor and the processors. A significant number of these applications require a quick and cost effective way to store and retrieve captured data. Often these embedded systems also have space, weight and power requirements. To address these needs, Curtiss-Wright Controls has designed, configured and delivered a data recording solution that is able to store data to cost effective SATA solid state and rotating disk drives. The Vortex VR-6511S8 is a VME/VXS recording engine. The recording engine includes two PMC/XMC sites and an on-board PowerPC™ 440SP, with 512MB of local SDRAM. The two PMC/XMC sites support a wide variety of I/O such as sFPDP, Gigabit Ethernet, 10GbE, and analog I/O. The VR-6511S8 includes an on-board Xilinx® Virtex®-5 SX95T FPGA with 512MB of local SDRAM and eight high-speed serial links to an industry standard VXS P0 connector. The VR-6511S8 uses the Virtex-5 to implement eight SATA controllers which can be stripped together for a high-speed rugged storage system. The FPGA provides access from the PowerPC CPU to the solid state Disk Carriers (VXS-4SSD) utilizing the VXS backplane. Each recorder engine can support up to eight SATA disks, connected one disk per P0 high-speed serial link. Each VXS-4SSD is fitted with up to four disks. The VXS-4SSD carriers are typically fitted with solid state drives. However, when used in more benign environments, it may be fitted with rotating SATA hard disk drives to significantly increase storage capacity and reduce cost. | |
