HPE HDR InfiniBand Switches and Cables QuickSpecs
Mellanox InfiniBand (IB) HDR Switches are supported to work with HPE InfiniBand Adapters to deliver high performance connectivity for HPC clusters using HPE ProLiant XL and DL Server families
The 1U switches feature 40 QSFP56 ports delivering up to 16Tbps of non-blocking bandwidth with sub-90ns port-to-port latency.
Ideally suited for Customers who deploy high-performance computing (HPC) clusters based on HPE ProLiant XL and DL Servers using InfiniBand technology.
Key features
- – 40 ports, each providing HDR (200 Gbps ) performance
- – 80 equivalent ports, each providing HDR100 (100 Gbps ) performance, using splitter cables
- – 16Tbps non-blocking aggregate bandwidth with sub-90ns port-to-port latency
- – In-network computing through the Co-Design Scalable Hierarchical Aggregation Protocol (SHArP) technology
- – Quick and easy setup and management
- – Multiple Virtual Lanes (VLs) per physical port
- – Improved performance by removing fabric congestion
- – Backward compatibility to Mellanox FDR and EDR InfiniBand technology for ease of migration
-
Features and benefits
Switch Specifications
- – Mellanox HDR IB 40P switches are based on Mellanox Quantum™ Switch Silicon 40-port ASIC with SHArP support
- – HDR (200 Gbps ) per port bidirectional
- – Switching capacity 16Tbps
- – Virtual lanes, configurable from one to eight VLs plus one management VL
- – Configurable MTU size of up to 4 KB
- – Maximum multicast table size: 16384 entries
- – Support QSFP56 passible copper and active optical cables
- – Compliant with IBTA 1.21 and 1.3
- – Adaptive Routing
- – Port Mirroring
HDR100
The Mellanox Quantum™ switch, when associated with ConnectX®-6 adapters, supports the HDR100 protocol. Two HDR100 adapters attached to an HDR splitter cable can be connected to a single port on the switch. Each adapter can then deliver 100 Gbps of bandwidth. In effect, this turns the Mellanox Quantum™ switch into a 80-port 100 Gbps InfiniBand switch, reducing the equipment required for a given fabric when compared to the previous generation and expanding the maximum number of node of a 100 Gbps two-level 1:1 fat tree topology to 1,600.
