Stop Worrying About Data Loss While Capturing Real-Time Sensor Signals

If you've ever been frustrated by data loss during real-time data capture at the most inopportune time, set your worries aside and consider using Anvil, Micro Memory's all-digital front end for real-time sensor data recording.

Anvil is a first-to-market SDRAM-based solution that eliminates the need to record directly to a set of hard disks with irregular transfer rates (see the figure). Instead, use Anvil to record your sensitive data stream. Its ample deep-memory buffers then can be used to write to a RAID configuration, ensuring the capture of sensor data without any loss.

With up to 64 Gbytes of dual-access SDRAM and using a Linux file system, Anvil is ideally suited for real-time data capture during signal reconnaissance, seismic analysis, fuel exploration, or telemetry. Or, use it when you require a large, deep memory for semiconductor testing or medical diagnostics.

Each of its two memory arrays can sustain data transfer rates of over 500 Mbytes/s and support simultaneous read/write operations. This data transfer rate handles high-bitrate bursts of data without the requirement to down-throttle or reduce the accuracy of recorded sensor data.

And since data is first stored in memory and then written to a hard-disk drive (HDD), a SATA-based (Serial ATA) HDD may be used in place of a more expensive SCSI-based or Fibre Channel-based HDD. This configuration also reduces the number of HDDs required to achieve the necessary bandwidth.

Anvil comes standard with four full-length/height PCI slots that include:

  • Analog-to-digital, serial front-panel data port
  • Custom low-voltage differential signaling or fibre links
  • Storage I/O for Fibre Channel, SCSI, or SATA.

Anvil is currently available with a list price of $30,000 per unit with volume discounts available.
