3U VPX switches and chassis have VITA 91 connectors to double backplane density

COTS board and systems supplier, Annapolis Micro Systems, claimed that the Wildstar 3U OpenVPX HD switch and chassis is the industry’s first COTS product to integrate high density VITA 91 connectors that double the available backplane density. It is in the final design verification, with customer shipping scheduled for December.

The WP3E20 Wildstar 3U OpenVPX Switch offers up to 128 pairs of Ethernet. The WILD100 13-Slot 3U OpenVPX Chassis (WC31DH) offers up to 64 lanes of Ethernet or PCIe, or 128 LVDS pairs.

The rugged WP3E20 switch is the latest version of Annapolis’ SOSA-aligned WP3E10 switch. Both models provide switching between backplane slots of multiple channels of 100Gbit Ethernet, front panel I/O, and separate data and control plane switches and two Zynq UltraScale+ processors that support encrypted secure communication.

The WP3E20 also has HD connectors, which deliver dramatic increases in bandwidth and reductions in latency, said Annapolis. It features up to 14 40/100Gbit and 24 1/10/25Gbit or six 40/100Gbit Ethernet ports.

The company said that two additional HD switches will also be released soon. These are the Wildstar 3P20 3U VPX PCIe/LVDS switch, for up to 128 LVDS or eight 8x PCIe interfaces.  The Wildstar 3H20 3U VPX combo switch combines 40/100GbE, Gen4 PCIe and/or LVDS

The WC31DH 19-inch rackmount chassis is a front-loading forced-air, conduction-cooled model with 13 3U OpenVPX slots. It includes eight primary RF/compute intensive payload slots with a 14.6.11 profile. There are also two HD switch profiles, one timing slot with 14.9.2 profile and two 12V-only VITA 62 power supply slots,

The two HD switch slots allow the WC31DH chassis to handle all data and control plane Ethernet via one slot, with the second switch slot dedicated to the expansion plane which can be Ethernet, PCIe and/or LVDS. This enables deployment for low latency jamming or radar applications.

“The new VITA 91 high-density connector allows for a completely switched backplane, so the expansion plane is no longer defined by a fixed backplane PCB, but is now fully reconfigurable,” said Jay Grandin, Annapolis Micro Systems vice president of product development.

“This not only allows for all the slots to be on the same non-blocking Ethernet switch instead of two switches chained together, but it facilitates a flexible, programmable expansion plane. The expansion plane supports either eight Gen4 PCIe, four Gen4 PCIe and eight LVDS, or 16 LVDS to each payload slot using the WP3P20 Switch which is software-configurable on a per slot basis. With the double-density WP3E20 100GbE switch, two existing standard VPX switch slots can be combined into a single high-density switch slot, freeing up a slot for the WP3P20 expansion plane switch.”

The chassis includes a secure Wild chassis manager (WABGM2). It is SOSA-aligned and VITA 46.11 compliant and is powered by a Xilinx UltraScale+ ZU11EG MPSoC and Microsemi PolarFire MPF200T FPGA for security functions. Multiple security and advanced features are available; contact factory for details.

The new switches and chassis join the Annapolis Wild100 EcoSystem of products, most of which were developed in alignment with the Sensor Open Systems Architecture (SOSA) Technical Standard and support C5ISR/EW Modular Open Suite of Standards (CMOSS). The EcoSystem is an interoperable portfolio of rugged high-performance OpenVPX COTS boards and systems that are used for challenging data acquisition, digital signal processing, and data storage applications and includes 3U and 6U baseboards, storage, switches, chassis and backplanes and SOSA development kits.

Board support packages include 40/100GbE IP and both VxWorks 7 and Linux support.
