The Compact Network Storage 4-slot (CNS4) is a conduction-cooled, high-performance network file server with scalable storage and encryption options. CNS4 is network-agile supporting CIFS, NFS, HTTP, FTP, and PXE protocols making it ideal for sharing critical data in a harsh environment. The CNS4 is designed to accept 4 memory modules and can support up to 8TB of removable solid state storage. The CNS4 is a modular design consisting of a full ATR Chassis and up to four Flash Storage Modules (FSM-C). These FSM-C modules plug into the CNS4 backplane and are housed behind an easy-to-open access door. Watch the video above and download the CNS4 product sheet to learn more.

Scalable Storage Up To 8TB

The CNS4 Network File Server chassis is designed to accept 4 memory modules. The FSM-C memory module has a current capacity of 2TB each. Thus the total CNS4 storage capacity is 8TB. It is expected that NAND Flash density will double every 18 to 24 months.

Flexible I/O - 1GbE / 10GbE / sFPDP

The CNS4 has been designed from the ground up for flexible inputs and outputs. Modern avionics or sensor management systems are designed around Ethernet – 1GbE or 10GbE. CNS4 has four 1GbE ports built-in. By connecting to four Ethernet switches, the CNS4 can be connected to a vast amount of mobile network clients.

CNS4 also has a 3U VPX slot for additional I/O. A special VPX carrier can host any type of XMC I/O card. For instance, a 10GbE XMC I/O card can be used providing connection to any 10GbE network for very high speed file server applications.
