Kraken Sonar Systems Inc. today announced DataPod, a removable data storage module for subsea marine applications. According to the manufacturer, the unit combines the ease of use of Network Attached Storage with the reliability of a RAID array and solid state storage all in one compact unit.
Many of today’s Autonomous Underwater Vehicles (AUV) are intelligence, surveillance and reconnaissance platforms and as such gather an enormous amount of streaming data from an array of sensors. In underwater environments, acoustic communications for telemetry have limited bandwidth, so the desire to capture and store large amounts of data for post-mission analysis always exists.
As a result, most solutions require easily removable and transportable storage devices. This ensures data can be readily delivered to the operator for post-mission review, enables users to reload and relaunch the AUV platform with new storage capacity quickly and avoids the lengthy downtime associated with downloading many terabytes of data from an AUV.
Data-critical sensor information must be delivered quickly and reliably. Military operators not only require as much, if not more, storage capacity as a commercial user, but also must take into consideration a variety of other requirements, such as a security concerns; size, weight and power considerations and the ability to withstand harsh environmental conditions.
“It’s imperative for both military and commercial users to utilize the newest and most efficient technologies such as optimized Network Attached Storage in order to achieve cost savings and increased efficiency,” said Karl Kenny, Kraken’s President and CEO. “Our DataPod system provides customers with a cost-effective solution that allows them to address subsea data storage challenges.”
DataPod utilizes the latest solid-state disk drive technology to provide a high-density, reliable, removable data storage solution. The unit enables high bandwidth recording with up to 2.5 Terabytes of storage (2 TB in RAID configuration) in a 1000m depth rated pressure module. It weighs less than 3 kilograms and is built to withstand extremes in temperature, shock, vibration and water integrity.
No tools are required to remove the module making it ideal for applications where removal and replacement of onboard storage must be quickly accomplished. DataPod modules can be easily transported and used interchangeably. A wet-mateable connector enables operators to “hotplug” and “hotswap” the module without powering down the host system to change modules. DataPod uses a standard Gigabit Ethernet interface to plug directly into a personal computer or a local/wide area networks.
In addition to AUVs, other DataPod applications include unmanned surface vehicles, subsea surveillance, surface buoy data collection, environmental monitoring and harbor security.
