Migrating from HyperFabric to other interconnect solutions such as Infiniband and Gigabit/10-Gigabit Ethernet

• Network bandwidth

• Fabric Management

Capabilities of InfiniBand

InfiniBand is a standard-based interconnects that enables the following:

• High-bandwidth, 10 Gbps connectivity. With PCIe, it provides 20Gbps in each direction.

• Extremely low-latency Remote Direct Memory Access (RDMA)

InfiniBand Transport Services

The InfiniBand transport-service types include the following:

• Reliable Connection

• Unreliable Connection

• Reliable Datagram

• Unreliable Datagram

HP only supports Reliable Connected and Unreliable Datagram transports in its fabric product.

High Availability features of Infiniband

The following are the high availability features of Infiniband

• Online Addition and Replacement (OLAR) enables adapters to be added, deleted and

replaced while the system continues to run.

• PCI Error Recovery

• Support of MC/Service guard - ensures Mission Critical IT demands are fulfilled

PCI-X - 10 GIGABIT Ethernet

The demand for higher speed networks coupled with the pervasiveness of Ethernet deployments over

the past 30 years resulted in the creation of 10 Gigabit Ethernet IEEE 802.3ae standards.

HP's leading edge PCI-X 10 Gigabit Ethernet adapter provides exceptional bandwidth in one large

pipe and supports many of the innovative features provided by its Gigabit Ethernet predecessor. In

the future, because of its high bandwidth and flexible nature, HP PCI-X 10 Gigabit Ethernet will play a

vital role for paving the road to a unified fabric infrastructure; where network, clustering and storage

can coexist all over one medium; simplifying management, increasing reliability and reducing total

cost of ownership.

Also 10 Gigabit Ethernet Driver for AD386A on HP-UX enables support of AD386A PCIe 10 Gigabit

Ethernet cards running on HP-UX 11iv3 or 11iv2.

10GbE customers will recognize immediate gains from the following:

• Standards based IEEE 802.3ae ensures consistency across the strong ecosystem

• 64-bit PCI-X capability provides faster transmissions with lower CPU utilization

• 64-bit Management Information base (MIB) statistics allows data link service (DLS) to return

64-bit statistics

• Bi-directional bandwidth that can deliver up to 11.8 Gbps with 1500 MTU.

• IEEE conformance for use of multi-mode fiber, supporting operating distances from 7' to 984'

(2 to 300 meters)

• Quality engineered stateless protocol offload features that maximize host efficiencies and

optimize bus utilizations by reducing host processing loads

• Modular design that can support various connectivity options and software enhancements
