Highlights
- High performance FDR (Fourteen Data Rate) speed that can auto negotiate to QDR (Quad Data Rate) speed also.
- Offers up to 18 uplinks ports for 14 servers allowing high speed throughput with zero oversubscription.
- Suited for clients running InfiniBand infrastructure in High performance Computing and Financial Services.
- Less than 200ns latency node to node
- Fully maximizes the Gen3 server architecture
- Forward Error Correction – Resilient
- Low power consumption
- Can scale to larger node counts to create a low latency clustered solution and reduce packet hops
As transaction volumes rise, your existing compute and storage clustering interconnects may have trouble keeping up. Yet you know that response time matters—you have to keep up with the competition and new regulations demand real-time risk analysis. You need to be able to scale your network and storage capabilities to meet the demands of your applications.
The IBM Flex System™ IB6131 InfiniBand Switch is designed to offer the performance you need to support clustered databases, parallel processing, transactional services and high-performance embedded I/O applications, reducing task completion time and lowering cost per operation. Virtual Protocol Interconnect also simplifies system development by serving multiple fabrics with one hardware design.
This switch is designed for low latency, high bandwidth, and computing efficiency for performance-driven server and storage clustering applications. Combined with the InfiniBand FDR adapter, your organization can achieve efficient computing by offloading from the CPU protocol processing and data movement overhead such as RDMA and Send/Receive semantics allowing more processor power for the application. CORE-Direct™ brings the next level of performance improvement by offloading application overhead, such as data broadcasting and gathering, as well as global synchronization communication routines.
