What is a 6U card?

What is a 6U card?

Two common heights are 3U (a 100 mm card in a 5.25 in (133.35 mm) subrack) and 6U (a 233.35 mm card in a 10.5 in (266.70 mm) high subrack).

What is 6U form factor?

6U VPX (VITA 46) Standard VPX is the ANSI/VITA 46 standard that incorporates high-speed serial fabrics to facilitate high volumes of data transmission. Like its predecessor, VME, it is available in two sizes, 3U (VPX3) and 6U (VPX6). It offers designers the license to choose the format best suited to each application.

What is a VPX card?

The VPX (ANSI/VITA 46) standard defines a set of standard form factor options for high-speed communication in switched serial fabrics such as Ethernet, PCI Express (PCIe), Serial RapidIO® (sRIO®), and Aurora.

What VPX means?

VPX, also known as VITA 46, refers to a set of standards for connecting components of a computer (known as a computer bus), commonly used by defense contractors. Some are ANSI standards such as ANSI/VITA 46.0–2019. VPX provides VMEbus-based systems with support for switched fabrics over a new high speed connector.

What is VME form factor?

VME (Versa Module Europe) is one of the early open-standard backplane architectures. It was created as a way to have a community of companies creating interoperable computing systems with the same form factors and framework.

What does 3U form factor mean?

The compact 3U VPX form factor reduces the size, weight and power (SWaP) needed to run rugged, mission critical applications, with powerful processing chips and high speed serial interconnects, today’s 3U performance can exceed yesterday’s 6U performance. Many applications are switching from 6U to 3U VPX form factor.

What is the difference between VME and VPX?

While VME was based on a bus, with signals daisy-chained at each slot, VPX is based on switched fabrics. One way to think of the bus is like a tollbooth. When there’s just one manned tollbooth, all of the cars in line have to wait for the ones in front of them to finish their transaction before they can go.

What are VITA standards?

The VITA 47 group of standards defines environmental, design and construction, safety, and quality requirements for commercial-off-the-shelf (COTS) Plug-In Modules intended for ground and aerospace applications. VITA 47.3 addresses requirements specific to high performance electronic products.

What does VME stand for?

VME

What is VPX and VME?

What is VPX Backplane?

VPX is a broadly defined technology utilizing the latest in a variety of switch fabric technologies in 3U and 6U format blades. The Open VPX framework defines clear interoperability points necessary for integration between Module to Module, Module to Backplane and Chassis.

What is a 3U server?

A 3U rack server is the smallest rackmount system that can incorporate full height and full length PCI or PCIe expansion cards in a vertical position without the need for a riser card. …

Can a 3U card be used on a 6U board?

However an adaptor card could always be used to re-format a 3U card into a 6U card. A 3U to 6U adaptor card would accept the 3U card from one end but plug into both connectors of a 6U size board. Of course the P2 connectors which make up the other half of a 6U interface would go unused.

How big is a 6U VME bus card?

Three basic VMEbus card [Dimensions] sizes are shown above, which include 9U, 6U, and 3U. Two 6U card sizes are depicted. The VME64 spec added the P0 connector between P1 and P2 on the 6U size card (not shown). IEEE 1101.1 Base Document for Mechanics ~ Defines 3U/6U/9U (high) x 100/160/220/280/340/400mm (Long) cards

How big is a 3U bus CCA card?

Three card heights are allowed with VME; 3U, 6U, or 9U; a single slot card is 6T wide. Length is either 160mm or 340mm (Norm) A size CCA dimensions = 3U x 160mm. A 3U Printed Wiring Board [PWB] is 100mm high. B size CCA dimensions = 6U x 160mm.

How tall is a 3U card in a rack?

The height of the card in a 3U rack is therefore 100 mm. As two stacked 3U cards are the same height as a 6U card, this scheme allows racks to be constructed which mix 3U and 6U cards.
