E-services, enterprise resource planning (ERP), and technical and parallel applications demand more computing power than single systems can sometimes deliver. Hewlett-Packard's innovative
Hyperfabric2 (HF2) clustering solutions provide the performance scalability and high availability these applications need.
HP's Hyperfabric2 products are composed of high-performance network switches, I/O interface cards, and communications software. The Hyperfabric2 family of network interconnect products provide
high-speed, low-latency solutions for clustering HP-UX Enterprise Server systems.
In addition to high performance, HP's Hyperfabric2 driver software has been optimized to ensure low CPU utilization. The standard TCP/IP communications stack has been tuned to reduce the delays
normally associated with moving data from network media to the application layer and back down to the media.
The family of products also offers the flexibility to connect systems in point-to-point or switched topologies, both of which can be implemented in a variety of high availability configurations. To
protect continuous system operations, Hyperfabric2 includes built-in high availability features such as error detection, redundant components, fast failover, and active-active mode, helping to
maintain application and data availability at all times.
Bundled within Hyperfabric2 is HP's patented Hyper Messaging Protocol (HMP), a messaging-based protocol that significantly enhances performance of parallel and technical applications by optimizing
the processing of various communication tasks. HMP has received numerous praises within the industry! HMP was jointly developed with Oracle®, and the resulting Hyperfabric2 feature set was tuned
to enhance the scalability of Oracle's Cache Fusion clustering technology.

Hyperfabric2 (HF2) features and benefits
| Features |
Benefits |
very high link bandwidth:
- 320 MB/s + 320 MB/s duplex per link
|
large pipe for fast data transfers through the network, without the worry of bottlenecks |
ultra-low latency:
|
transportation delays for sending and receiving data are significantly less when using
Hyperfabric2 Hyper Messaging Protocol (HMP) than when using standard protocols. For many applications, latency is a critical component to maximize performance; for Oracle's clustering technology,
latency determines the speed of data block transfer between nodes. Efficient data transfer methods help to reduce processing workloads
|
| up to 50% less CPU utilization |
networking communication tasks are offloaded from the CPU, allowing the processing power to be available for other demanding tasks |
| increases speed and reliability of tape backups |
quantity and speed of reliable centralized tape backups is increased to more than 7 terabytes/hour |
| high availability configurations |
- link-level heartbeats provide fast detection of link failure
- high availability capable in active-active or redundant-switch modes.
Once activated, immediate failover occurs, allowing all Hyperfabric2 cards on a system to carry traffic simultaneously while protecting your valuable data
|
| online addition and replacement (OLAR) of I/O cards |
reduces need for unplanned downtime |
| hyper messaging protocol (HMP) |
- HP's low-latency, low-CPU-consumption, messaging-based patented protocol
- reduces the need for disk writes/copies, improving overall system performance
- increases scalability of key parallel applications, such as Oracle's OPS and RAC
|
| flexible switched or point-to-point configurations |
- connectivity for up to 64 HP Enterprise Servers in switch mode connectivity
- point-to-point connectivity is system dependent and is determined by the maximum number of cards supported
- network consolidation is realized when interconnecting multiple servers with Hyperfabric2; high throughput is sustained, yet fewer I/O slots are required
- provides highly scalable growth path
|
| provides transparent load balancing of connection traffic across NICs |
data is managed across links to optimize network performance |
