Performance and Recommended Use of AD385A 10 Gigabit Ethernet SR Cards

Table Of Contents

Features and Benefits of the AD385A

Features and benefits of the AD385A include:

• PCI-X operation in 266MHz, 64-bit mode.

• Conforms to IEEE 10GBASE-SR using multi-mode fiber. Operating distances from 7 to

984 feet (2 to 300 meters).

• Supports several features that improve CPU utilization:

— Jumbo Frames with a maximum transmission unit (MTU) of 9000 bytes.

— On board TCP Segmentation Offload (TSO) of IPv4.

— On board Checksum Offload (CKO) for TCP, UDP and IPv4.

• All onboard memory and storage are ECC protected; with single bit errors automatically

corrected and double bit errors detected.

• Supports HP Serviceguard and Auto-Port Aggregation (APA) for high availability. APA is

currently supported only in Lan Monitor mode for high availability.

• Supports PCI-X online addition/replacement (OLA/R) on specified systems.

• Supports 64-bit management information base (MIB) statistics. Directs the data link

service (DLS) provider to return 64 bit statistics.

• Supports subnetwork-access protocol (SNAP) network-layer protocol encapsulation.
