Description

DESCRIPTION
A DATA LOAD UNIT Field of the Invention
The present application is related to network attached storage which is especially designed to manage network storage on aerial platforms via Ethernet. In detail, data load unit is a microprocessor based unit which is designed for avionic applications, and provides access to mission data or file systems via ethernet, using the standard file sharing protocols such as SMB (SAMBA), FTP (File Transfer Protocol) or TFTP (Trivial File Transfer Protocol). The inventive data load unit is designed to meet the requirements of special military standards, and it is suitable to be installed on both rotary winged and fix winged aircrafts.
Background of the Invention
In the background of the invention, various data load units are used in order to access to the stored data via MIL-STD-1553B or 100 BASE-T interfaces in military applications, and especially in the aerial platforms. Data load units should have a fast communication protocol with the end points that are connected to the file system. However, as in the background of the invention, data retrieval and recording speeds are considerably slow, because the interface which is used for the communication is MIL-STD-1553B or 100 BASE-T Ethernet standard on data load units. In this case, access to large sized files takes long time, and additionally data access times of the end points that are connected to the data load unit are also longer. Moreover, there is usually only one MIL-STD-1553 or 100 BASE-T Ethernet interface on the data load unit and thus access to the data load unit from several end points is not possible and there will be necessity of another management layer or unit in order to organize the access to the data load unit. Data load units are using nonstandard memory cards or physically large sized standard memory cards such as "PCMCIA" (Personal Computer Memory Card International Association). For instance, PCMCIA cards have the approximate size of 54 mm x 85.6mm x 3.3mm, and their data storage capacity is limited to maximum of 16 Gigabytes. In military applications, and especially in aerial platforms, there is not much free space for the required electronic units. In this limited environment, balancing the load distribution also becomes very tough. For this reason, electronic units that are designed by large mechanical size modules become heavy and large. Thus they may cause weight and volume problems in aerial platforms,. On the other hand, these memory cards do not have sufficient storage medium, even though they have large physical sizes. As a result, it is not possible to manage and record large sized files on these memory cards.
Problems Solved by the Invention
The main aim of the invention is to provide a data load unit, that has the required processing power and interface capability, to function in harsh military conditions. The data load unit is developed according to the environmental requirements that are defined by the military standards (MIL-HDBK-5400, MIL-STD-810, MIL- STD-704 and MIL-STD-461) and within this scope, altitude, high and low temperatures, thermal shock, humidity, vibration, mechanical shock, salt spray, rain, acceleration, temperature-altitude, temperature-vibration, power and EMI/EMC tests are conducted on the unit. Another aim of the invention is to provide a data load unit that can provide fast and reliable access to stored data and files via Ethernet network topology, using the standard file sharing protocols such as SMB (SAMBA), FTP (File Transfer Protocol) or TFTP (Trivial File Transfer Protocol) by the processor board on unit. Another object of the invention is to provide a data load unit that has 100 BASE-T Ethernet switching capability which enables not only the Ethernet communication to/from the data load unit but also the Ethernet communication in between end points.
On the data load unit, CompactFlash™ technology is used as storage medium. By the CompactFlash™ technology, the memory of the data load unit can be increased flexibly and without need for hardware changes. Data load unit can process fast and secure purge for the security of the critical mission data,
