Critical recording benefits from cryptic measures
With more and more sensitive data being captured in data recording systems, the benefits for securing data via encryption are becoming stronger. Encrypting stored data renders it inaccessible without keys, diminishes the need to physically secure storage units and removes the need to implement secure erase functions. Encryption standards such as AES have received broad commercial acceptance, and IEEE P1619 is being established for even more advanced storage encryption. These algorithms have the benefits of transparent encryption, making them well suited for use in storage applications. Off-the-shelf IP has emerged to help deploy these algorithms.

Ultra-wideband recording stretches to keep up with digitizers
Systems designers are always pressing for faster and faster real-time performance, and data acquisition technology continues to evolve to meet that need. Currently available high-performance digitizers perform in the range of 2 to 5 GS/sec, and some new instruments are featuring 7 GS/sec digitizers for transient capture.
Often, advances in one area of technology put pressure on others, and in this case these faster digitizers have created a corresponding need for faster data recording to capture the digitized results in real-time. Streaming data recorders are currently capable of data rates in the range of 720 MB/sec, which is quite fast but still means a single recorder is incapable of recording all the data from one of these advanced digitizers.
With some architectural insight and utilization of advances in serial FPDP interfaces, recording engines, switching, and storage arrays, however, an ultrawideband streaming data recorder can be created to keep up with these advanced digitizers.

Storage for Harsh, Harsher and Harshest Mil Environment
Mass storage for military systems demands robust approaches to survive in harsh applications. Rotating media performs reliably in many applications of packaged appropriately, while flash media is required in the most extreme environments. While commercial commodity storage technology continues to improve in cost and density, most of it is practically useless in a typical military application beyond the lab or ground shelter without some proactive packaging innovation.

Military data storage: tough enough for duty
Using mass storage in military embedded systems presents environmental challenges not found in most commercial applications, but with the right packaging, hard disk drives perform reliably in many applications, even some that are extremely harsh at first glance. Analyzing the key parameters found in various classes of applications can aid in designing storage subsystems with the right underlying technology.

Fibre Channel for high-speed high-capacity data storage
Mass storage devices required for data recording systems can be as varied as the recording system being used. Deployed airborne systems require rugged sealed mass storage, whereas lab systems may require large COTS mass storage systems. Issues to consider include high-speed, long duration recording or short snapshot recording; system configurations; types of mass storage; and how the system is to be used. Here, the authors advocate Fibre Channel as the means to connect to the storage or recorder system, and the types of mass storage to be discussed include JBOD, RAID, rugged sealed storage, and solid-state products that can work at high altitudes.

High-speed recording needs more than just storage capacity
This article discusses the use of ruggedized JBOD storage solutions used in the US Air Force's U-2 surveillance plane. Applications in airborne intelligence, surveillance and reconnaissance have always demanded that recording systems capture large amounts of data.

1 GHz Digital Data Recorder
Just 5 years ago, it was unthinkable that a mobile system could perform sustained recording at the 2 Gbyte/s rate needed for a 1-GHz recorder. Virtually all such recorders used limited amounts of on-board memory to provide a few seconds of snapshot recording. However, digitizer boards have greatly increased sample rates with faster interfaces and lower power requirements. In addition, significant improvements have been made to the data recording engine, including CPU power, memory speeds, and data paths from input to storage. These improvements have allowed VMETRO to build an ultra-wideband digital data recorder with the performance required for radar analysis, SIGINT, ELINT, and other data-hungry applications.
