Features and Benefits of the AB287A
Features and benefits of the AB287A include:
• PCI-X operation in 133 MHz, 64-bit mode.
• Conformance to IEEE 10GBASE-SR using multi-mode fiber. Operating distances
from 7 to 984’ (2 to 300 meters).
• Support for several features that improve CPU utilization:
Ø Jumbo Frames with a maximum transmission unit (MTU) of 9000 bytes.
Ø On board TCP Segmentation Offload (TSO) of IPv4.
Ø On board Checksum Offload (CKO) for TCP, UDP and IPv4.
• Support for multiple inbound and outbound queues. This allows traffic to be
distributed to multiple processors and prevents saturation of a single processor.
VLAN priority and destination port based packet steering are supported.
• All onboard memory and storage are ECC protected; with single bit errors
automatically corrected and double bit errors detected.
• Support of HP Serviceguard and Auto-Port Aggregation (APA). APA is currently
supported only for high availability.
• Virtual LANs (VLANs to provide increased network flexibility).
• Online addition/replacement (OLAR) on supported systems.
• Support of 64-bit management information base (MIB) statistics. Directs the data
link service (DLS) provider to return 64 bit statistics.
