PCI-X 4-Port 10/100/1000 Quad Gigabit Ethernet, 64-bit

AEI Intelligent Technologies' PCI-X quad port 10/100/1000 Gigabit Ethernet network interface card (AEI-1400C) is designed to deliver high performance, and high reliability for demanding applications, as well as legacy Fast Ethernet connectivity.  It provides a full-duplex Gigabit Ethernet connection on a Universal Short Card .  The Gigabit Ethernet interfaces provides unparalleled server throughput that helps reduce administrative complexity by replacing multiple slower interface cards with a single Gigabit adapter.  


AEI's adapters are the perfect solution for a cost effective, instant performance boost over existing Category 5 UTP copper cabling.  It also offers scalability for those contemplating future upgrades to Gigabit technology.

As a Server Class Adapter Card, the AEI-1400C supports Windows and Linux Advanced Server Features (Trunking, and Failover).

Moreover, the AEI-1400C can be user configured to enable or disable IRQ Coalescing.  That is, all four ports share one interrupt, or IRQ.  This is a particularly useful feature in port density applications such as firewalls and cluster environments.

Design Characteristics

The AEI-1400C supports and auto-negotiates between 32/64-bit, and 33/66/100/133 MHz datapaths. Built with PCI-X technology, the AEI-1400C supports standard PCI 2.1 and 2.2 specifications, and also PCI-X motherboards for clock speeds into the 133 MHz range.  It is uniquely designed with integrated magnetics, low profile surface mount resistors and capacitors, high precision oscillator, and other high-end discrete components.  The result is a card that is highly reliable, resistant to damage, fault tolerant, and performance that is unparalleled.  The AEI-1400C is fully interoperable with existing Fast Ethernet or Gigabit Ethernet hubs, switches and routers.   


Jumbo Frame

The Gigabit adapter is configurable to support Jumbo Frame (9KB)


Advanced Server Features
AEI's Gigabit adapters utilize the popular Intel 82546 chipset, which comes with numerous advance server features built into its architecture. Hardware acceleration offloads tasks from the host processor including TCP/UDP/IP checksum calculations and TCP segmentation.  Link aggregation, failover, and load balancing are offered, and the adapter is also fully compliant with Gigabit EthernetChannel and Fast EtherChannel trunking algorithms.   (switch dependant 802.3ad [LACP] )
