4.3. Universal 4-Port 10/100 Ethernet Adapter (DCCG152, DCCG162)
The Universal 4-Port 10/100 Ethernet Adapter is a single slot, long, 64-bit, 33 MHz PCI adapter
supporting 4 industry standard Ethernet 10 Base-T or 100 Base-T interfaces either half or full duplex.
Each port is provided with its own RJ-45 connector for attachment to standard CAT-3/5 Unshielded
Twisted Pair (UTP) cable. The adapter is IEEE 802.3u compatible and provides full auto-negotiation
for detecting speed and duplex capability across each port.
Network boot capability and Network Install Manager (NIM) capability are available using this
adapter if no specific limitation is stated.
The Universal 4-Port 10/100 Ethernet Adapter should be considered where maximum port density is
required per I/O card slot. But, for high end systems, where card slots are not the limiting factor and
maximum throughput is required, the single port 10/100 Mbps Ethernet PCI Adapter (DCCG137 or
DCCG143) is the preferred solution.
Below are some performance factors to consider when choosing the right adapter for your needs.
These performance comparisons are based on all four ports of the Universal 4-Port 10/100 Ethernet
Adapter being active.
•
With all four ports under full bandwidth conditions, a single Universal 4-Port 10/100 Ethernet
Adapter is expected to deliver up to 3 times the comparable performance of a single 10/100 Mbps
Ethernet PCI Adapter.
•
Under most conditions, each port of the Universal 4-Port 10/100 Ethernet Adapter is expected to
perform at greater than 50% the throughput of the single port of the 10/100 Mbps Ethernet PCI
Adapter.
Note:
The resulting performance in your environment compared to the above may vary and depends
upon the Escala model, the I/O configuration, and associated workload of your applications.
