IBM 5719 10 Gigabit Ethernet-LR PCI-X Adapter

IBM 10 Gigabit Ethernet LR PCI X Adapter. It is server based

connection over a maximum distance 10 km. It’s IEEE standard

802.3

What is Ethernet Ethernet is most widely used LAN

technology. Specified in by IEEE 802.3. It was originally developed by Xerox corporation. It basically used coaxial

cable or twisted pair. First Ethernet 100 BASE-T provides transmission speeds

up to 100 mbps.

PCI X Gigabit Ethernet

PCI X stands for PCI-eXtended it is a computer bus and expansion card for

the 32 bit. It is double wide version PCI running up to four times clock speed.

IBM HP and Compaq jointly developed this PCI X in the 1998. In the master

slave architecture when master issue request it disconnect from PCI bus for

other agent use it. Embedded application frequently used real time

processing using PCI X.

Ethernet and IEEE 802.3 is almost similar technology. Both are CSMA/CD LAN. These are the broadcast network

they all see frames regardless the station. For processing, frames are

passed to the higher network protocol.

IBM 5719 10 Gigabit Ethernet-LR PCI-X Adapter

Feature of IBM Gigabit Ethernet Adapter

1) Latest 1GbE controller technology.

2) Configurations are quad and dual port.

3) Microsoft VMQ support.

4) Energy efficient.

5) Support precision time protocol.

Latest 1GbE controller technology

Configurations are quad and dual port

Based on the Gigabit Ethernet controller dual port and quad port server adapter is the fourth generation PCI express Gigabit Ethernet. Using the combination of dual

port and quad port it improves the flexibility and connectivity.

Microsoft VMQ support

VMQ are virtual machine queue. It is hardware virtualization technology for different network traffic

like TCP/IP. It transfer all incoming and outgoing frames those stored in a buffer memory. Using

virtualized server technology it improves it’s performance.

Energy Efficient

It reduces adapter power consumption up to 42% using power

management and adjusting data traffic load.

Support precision time protocol

PTP used for synchronization of clock throughout computer networks. In the LAN it achieves clock frequency in the

microsecond range. Using PTP it achieves greater speed and

synchronization time in the network.
