840 Quad Small Form-factor Pluggable (QSFP28) 100GB adapter - InfiniBand (IB), Enhanced Data Rate/Ethernet (EDR/EN), 1-port.
Relevant part numbers: CX455A; 825315-001; 828107-001; 825110-B21
HPE EDR InfiniBand/Ethernet 100Gb 1-port and 2-port 840QSFP28 Adapters are based on Mellanox ConnectX®-4 technology. They support dual-function InfiniBand and Ethernet for HPE ProLiant XL and DL Servers. The single ported card can function as a single port EDR InfiniBand card, or a single port 100Gb Ethernet card; the dual ported card can function as a dual ported EDR InfiniBand card, a dual ported 100Gb Ethernet card, or a mixed function card. They are designed for customers who need low latency and high bandwidth interconnector in their high performance computing (HPC) systems.
Combined with EDR InfiniBand Switches or 100Gb Ethernet Switches, they deliver low latency and up to 100Gbps bandwidth, ideal for performance driven server and storage clustering applications in HPC and enterprise data centers. 840QSFP28 adapters deliver up to 100Gbps EDR InfiniBand, providing the network performance needed to improve response times and alleviate bottlenecks that impact performance of customers’ applications. They are ideal for high performance computing clusters and datacenter servers that require low latency and high bandwidth networking.
