What is a switched mezzanine card?
What is a switched mezzanine card?
Switch Mezzanine Card (XMC & XMC 2.0) XMC is a PMC with high-speed serial fabric interconnect defined by the VITA 42 standard. XMC specifies an additional connector (P5) that support PCI Express(VITA 42.3) or other high speed serial formats such as Serial RapidIO (VITA 42.2) and Parallel RapidIO (VITA 42.1).
What is a mezzanine card used for?
A PCI mezzanine card (PMC) is a printed circuit board that is used to extend the connectivity or function of a compatible computer system, typically for the VMEbus, Futurebus+ and other computer systems supporting the PCI specification.
What is XMC board?
XMC Boards, High-Performance FPGA, Ethernet, and Carriers XMC cards and modules provide a rugged, embedded computing platform for high-speed data communication in military/defense, aerospace, and research lab systems.
What is mezzanine card in blade servers?
Server systems often comprise multiple server blades housed in a chassis and/or in standard rack mount. Expansion cards for blade servers may have a mezzanine design, in which the expansion card is inserted or installed parallel to the system board of the server.
What is XMC mezzanine?
XMC, or Switched Mezzanine Card, (PMC with high-speed serial fabric interconnect) defined by the VITA 42 standard. XMC specifies a fifth connector (“P15”) that supports PCI Express (VITA 42.3) or other high speed serial formats such as Serial RapidIO (VITA 42.2) and Parallel RapidIO (VITA 42.1).
What is a Mezz port?
Mezzanine is a term used to describe the stacking of computer component card s into a single card that then plugs into the computer bus or data path. The bus itself is sometimes referred to as a mezzanine bus. The term derives from the Italian word, mezzano , which means middle.
What is mezzanine in architecture?
A mezzanine is an intermediate floor (or floors) in a building which is open to the floor below. It is placed halfway up the wall on a floor which has a ceiling at least twice as high as a floor with minimum height. Mezzanines are commonly used in modern architecture, which places a heavy emphasis on light and space.
Who invented blade servers?
Blade servers were invented in the 2000s by Christopher Hipp and David Kirkeby at their company, RLX Technologies in Houston. Both Christopher Hipp and David Kirkeby were former employees of Compaq, one of the early companies to sell computers and computer products.
What is mezzanine card HP?
The mezzanine cards can fit onto any ProLiant or Integrity c-Class server blade. HP designed the server blades to use two types of mezzanine cards, referred to as Type-I and Type-II, to connect to the various interconnect fabrics.
What is Mezz port?
A mezzanine connector connects two parallel printed circuit boards in a stacking configuration. Many mezzanine connector styles are commercially available for this purpose, however PMC mezzanine applications usually use the 1.0 mm pitch 64 pin connector described in IEEE 1386.
What is PMC form factor?
The PMC bus is actually a form factor that is electrically the same as the PCI Bus, but the shape of the card and the bus connectors are different. The basic PMC module is a 32-bit data bus that uses two 64-pin connectors from the PCI bus. There is also a 64-bit version that uses three 64-pin connectors PCI.
What is the XMC mezzanine format?
The XMC mezzanine format is an evolution of the previous PMC (PCI mezzanine card) format. The XMC specification extends PMC with the addition of new connectors which support gigabit serial interfaces plus alternative I/O standards. The XMC connector is a pin-socket connector with 114 pins arranged in a 6 x 9 array.
What is a Vita 42 switched mezzanine card?
XMC [ VITA 42 ], Switched Mezzanine Card, is compatible with Compact PCI or the VME board standards, and ATCA carrier cards. The XMC board standard is based on the PMC mechanical definition, and occupies the same board area. Among the differences between XMC and PMC standards are the addition of a new set of connectors and a fabric interconnect.
What is the difference between Vita 42 and XMC?
XMC [VITA 42], Switched Mezzanine Card , is compatible with Compact PCI or the VME board standards, and ATCA carrier cards. The XMC board standard is based on the PMC mechanical definition, and occupies the same board area. Among the differences between XMC and PMC standards are the addition of a new set of connectors and a fabric interconnect.
What is a PMC mezzanine card?
PCI Mezzanine Card. The PMC standard defines which connector pins are used for which PCI signals; in addition it defines the optional 64 “P4” connector pins for use of arbitrary I/O signals. It enables manufacturers to offer products that are compatible with the well-established PCI bus, but in a smaller and more robust package than standard PCI…
