Vmetro has extended its range of real-time data recorders with the next generation MDR Midas data recorder, using the latest in sensor I/O and storage technology. MDR is a family of ready-to-run recorders for front panel data port (FPDP), FPDP II and 2.4Gbit/s serial FPDP high-performance embedded data acquisition applications such as radar, sonar, intelligence and image capture. Depending on model and usage recording speeds between 80 and 180Mbyte/s can be attained.
The MDR can use Fibre Channel JBOD and RAID systems as storage devices, and is delivered as a single VME card.
The software includes essential striping algorithms necessary to work with low-cost JBODs, distributing the data through an advanced buffering system to several disks concurrently in order to sustain the high total transfer rate.
Complete flexibility and scalability in the storage system is provided by the advanced disk grouping system, allowing any set of disks in a Fibre Channel SAN (storage area network) to be virtualised as a single storage unit.
Several disk groups can be managed at the same time, with typical applications using two groups in an alternating mode, where one is recorded to, while the other can be read from, ensuring simultaneous access at full speed.
Fast precitable, real-time access to each storage device (disc group) is managed by Vmetro's high-performance file system.
Terabytes of data acquisition storage can be easily managed from custom applications by accessing the recoding table that is written to each device.
The MDR product is supplied with host software that runs under Windows2000 or Sun Solaris for data readback, upload and management of the recorder functions.
The MDR starts shipping to customers in November 2002.
It is available in commercial and ruggedised versions.
Prices start at US $19,800.
