What is the switching capacity and latency?

It provides 2 Tbps capacity at FDR and 1.44 Tbps at QDR with full bisectional bandwidth. Node-to-node latency is under 170 ns at FDR speeds—nearly half of QDR—plus Forward Error Correction for resilient, low-packet-loss performance in clustered environments.

Is it compatible with Flex System chassis?

Yes, designed as a plug-in module for Flex System Enterprise chassis, connecting 14 internal ports to compute nodes. Pairs with IB6132 dual-port mezzanine cards for FDR/QDR links, integrating into high-bandwidth, low-latency datacenter fabrics.

What management options are available?

Includes 1GbE port to chassis management module, RJ-45 Ethernet, and RS-232 mini-USB serial ports. Features PowerPC MLNX-OS with in-band agents; requires external subnet manager. Supports 48K unicast/16K multicast addresses and nine QoS virtual lanes.

What are ideal applications for this switch?

Optimized for HPC clustering, parallel processing, transactional services, and embedded I/O in datacenters/financial services. RDMA offload reduces CPU overhead; scales for larger node counts with 18 uplinks and zero oversubscription for 14 servers.

Does it support FDR upgrade?

Yes, base QDR (40 Gbps) upgrades to FDR (56 Gbps) via FoD license, requiring compatible IB6131 FDR adapters. Delivers ultra-high performance with low power consumption and IBTA 1.3/1.21 compliance for enterprise-grade reliability.

Product overview

The IBM Flex System IB6131 InfiniBand Switch (SKU 90Y3452) is a managed plug-in module for Flex System chassis, providing 36 InfiniBand FDR/QDR ports including 14 internal ports at 40 Gbps QDR (upgradable to 56 Gbps FDR) and 18 external QSFP uplink ports supporting 10/20/40/56 Gbps auto-negotiation. It offers 2 Tbps switching capacity at FDR and 1.44 Tbps at QDR with full bisectional bandwidth and sub-170 ns node-to-node latency at FDR speeds. Designed for high-performance computing (HPC), enterprise datacenters, and financial services, it supports clustered databases, parallel processing, and transactional services via low-latency fabric. Features include Forward Error Correction, nine virtual lanes for QoS, 48K unicast/16K multicast addresses, and management via 1GbE/RS-232 ports. Compatible with IB6132 mezzanine cards, it reduces CPU overhead through RDMA, enabling efficient scaling for up to 14 servers with zero oversubscription.
