WILDSTAR 3SN0 3U OpenVPX SOSA-Aligned Storage – 32 TB/Slot

Annapolis offers the highest density OpenVPX storage solutions on the market, with up to 32.0 TB of capacity in a single 1” 3U slot, and up to 5 GB/sec read/write bandwidth. The WS3SN0 is a hot-swappable board (10,000 insertion cycles) with100GbE capability, and is developed in alignment with SOSA™.

Annapolis Storage Solutions are fully optimised for SIGINT, ELINT, EW, and other high-bandwidth storage applications.


The WS3SN0 is a SOSA aligned 3U data storage solution from Annapolis featuring up to 32 TB storage depth, and up to 5 GB/sec bandwidth, plus additional depth and bandwidth capacity using multiple cards.

One Xilinx® Zynq® UltraScale+™ MPSoC ZU11 Motherboard Controller allows stand-alone operation, and supports multiple levels of hardware and software security.

The board has a rugged design and is available in industrial temperature grades. Optional air, conduction, air-flow-through, and liquid-cooled environments are also available.

High-bandwidth backplane connectivity is enabled by MULTIGIG RT3 interconnects, which deliver 100Gb per Fat Pipe.

The 3SN0 is part of Annapolis’ growing WILD100 EcoSystem™, an interoperable portfolio of rugged high-performance 100Gb VPX COTS boards and systems.
