MONSSTR 6500 Recorders

The second generation of high speed, high capacity solid state recorders is now available from CALCULEX. Utilizing state-of-the-art components including the very latest in programmable gate arrays and processors, the MONSSTR 6500 represents the most versatile and capable solid state recorder available today. Following our tradition of innovative and compact designs, CALCULEX includes a number of I/O options including multi-channel IRIG 106 Chapter 10 multiplexer, enhanced resolution and high definition video, high speed Ethernet, fibre channel and 8-bit, 16-bit, or 32-bit parallel LVDS configurations. Removable multiplexer modules allow for quick mission reconfiguration with a minimum downtime and no reprogramming. The MONSSTR 6500 can be configured for one or two memory canisters for a total storage capacity of more than 2 Terabyte per recorder.

System Architecture

A minimum Model 6500 MONSSTR recorder configuration consists of an enclosure with a power module, a controller and one memory canister. The primary data I/O path into and out of the system can be configured to be either Gigabit Ethernet (GigE), 1 or 2Gigabit/sec (Gbps) Fiber Channel, or both. A Removable I/O Multiplexer Module ( RIMM ) with up to four separately configurable I/O boards can be installed in either one of the two memory canister slots in the dual canister chassis configuration. Figure 1 is a high-level block diagram of a two canister MONSSTR 6500 .

Power modules are available for use with AC or DC power sources. Standard power modules for ruggedized units are 115VAC/400Hz, 28 VDC and 270 VDC .

Storage Capacities

A single Model 6500 memory canister has a storage capacity of up to one Terabyte. Additional memory is held in reserve for internal housekeeping and error recovery. Partially populated memory canisters are available. The MONSSTR system architecture is designed to accommodate higher memory densities as they become available.

Data Rates

The maximum sustained data rate of a MONSSTR recorder is determined by the speed of the internal bus, the type of memory and configuration of the memory canisters, the I/O interfaces installed in the system, and the mode of operation. Model 6500 internal busses are capable of sustained data rates of up to 320 megabytes per second.

A 1Gbps Fiber Channel interface can sustain up to 80Megabytes/sec (MB/s) with SCSI protocol and 100MB/s with Serial FPDP protocol using large block transfers. 2Gbps Fiber Channel performance is approximately doubled that of 1Gbps Fiber Channel for either protocol. Maximum 1GigE throughput is also approximately 80MB/s with large block transfers but falls off quickly as block size decreases. Multiple independent Fiber Channels or GigE links can operate in parallel up to their individual link limits or until their aggregate data rate reaches the maximum sustained rate of the internal busses and memory canisters.

 Read-After-Write

All MONSSTR controllers incorporate data buffer memory that preserves user input data until it has been successfully stored in the memory canister. When read-after-write mode is enabled, the controller will read each data word after it is written to verify that it was written correctly. This feature may be enabled or disabled by the user equipment. Since two bus transfers are required for each word recorded in this mode of operation, the maximum net throughput is limited to one-half of the maximum internal bus data rate of the MONSSTR recorder.

Removable I/O Multiplexer Module

The RIMM may be configured to combine multiple video, voice, analog, digital, PCM, and MIL - STD -1553 data channels into a fully compliant IRIG 106 Chapter 10 data stream for recording. RIMMS can be ordered with different channel configurations and can be removed and replaced in the field to change the recorder data channel configuration between missions.

 Special Memory Operations

Special memory operations may be enabled or disabled by the user equipment. Circular buffer mode allows the MONSSTR recorder to overwrite the oldest data when the memory canister becomes full. Daisy-chain mode allows multiple MONSSTR recorders to be connected together such that when the memory in one is full, the next one in the chain will begin recording.

 Momentary Power Outages

MONSSTR power modules incorporate sufficient capacitance to support full-up operation of the recorder during power losses of up to 50 milliseconds. Loss of power for more than 50 milliseconds will result in a clean power-down sequence with no loss of previously recorded data.
