Applications

PCIE Server NIC card Application

  • PCI-E NIC Cards provide redundant connectivity to ensure an uninterrupted network connection.

  • PCI-E NIC Cards are ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs.

  • They are specially designed for desktop PC clients, servers, and workstations with few PCI Express slots available.

Introduction of PCI Express 2.0

 

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007. The PCIe 2.0 standard doubles the transfer rate compared with PCIe 1.0 to 5 GT/s and the per-lane throughput rises from 250 MB/s to 500 MB/s. This means a 32-lane PCIe connector (×32) can support throughput up to 16 GB/s aggregate.

 

PCIe 2.0 motherboard slots are fully backward compatible with PCIe v1.x cards. PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1. Overall, graphic cards or motherboards designed for v2.0 will work with the other being v1.1 or v1.0a.

PCI Express Base 2.0 specification doubles the interconnect bit rate from 2.5 GT/s to 5 GT/s in a seamless and compatible manner. The performance boost to 5 GT/s is by far the most important feature of the PCI Express 2.0 specifications. It effectively increases the aggregate bandwidth of a 16-lane link to approximately 16 GB/s. The higher bandwidth will allow product designers to implement narrower interconnect links to achieve high performance while reducing cost.

 

A number of optimizations and improvements have been made to the protocol and software layers of the PCI Express architecture in the PCI Express Base 2.0 specification. These include:

 

  • Dynamic link speed management - to control the speed at which the link is operating
  • Link bandwidth notification - to notify software (operating system, device drivers, etc) of changes in link speed and width
  • Capability structure expansion - to expand the control registers to better manage devices, slots and the interconnect
  • Access control services - optional controls to manage peer-peer transactions
  • Completion timeout control - to define a required disable mechanism plus related optional enhancements
  • Function-level reset - optional mechanism to reset functions within a device
  • Power limit redefinition - to redefine slot power limit values to accommodate devices that consume higher power

 

The PCI-SIG also said that PCIe 2.0 features improvements to the point-to-point data transfer protocol and its software architecture.
