The NC7170 features two ports on a single adapter, allowing customers to save valuable I/O slots for other purposes. Each port supports a PCI-X 64-bit/133MHz interface, which is also compatible with traditional PCI slots. The 10/100/1000Mbps capability enables the NC7170 to be used in Ethernet or Fast Ethernet legacy wiring plants, as well as for Gigabit environments. The high speed and increased data path, combined with the 128KB of onboard memory, make the NC7170 idea for ProLiant servers requiring the maximum in bandwidth with maximum port density.
