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.
IBM 5719 10 Gigabit Ethernet-LR PCI-X Adapter 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.
Feature of IBM Gigabit Ethernet Adapter 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 Transmitting of Ethernet frame in a Gigabit speed is called the GbE(Gigabit Ethernet). Higher bandwidth 10 GbE available when IEEE ratified standard in 2002. It support full line rate in all ports. In the high transaction environment requiring smaller packet it is ideal for that.
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.
