InfiniBand is a technology that utilizes a high-performance input/output (I/O) architecture that allows for simultaneous connection of multiple cable exchanges. According to their transmission rates and physical interfaces, InfiniBand cables are typically divided into four main types: QSFP, QSFP-DD, SFP, and AOC, fully supporting the business requirements of high-performance computing data centers.
In mainframe computing, the InfiniBand network model dedicated channel is used to connect and transmit data between the mainframe and peripherals. The maximum packet size of the InfiniBand network is 4K, supporting point-to-point and bidirectional serial links that can be aggregated into 4X and 12X units to achieve a combined useful data throughput rate of up to 300GB per second.
In order to further promote the development of the high-performance computing industry, many brands have started launching InfiniBand products. Mshine provides 100G QSFP28 IB optical modules and cables, which can be used as one of the solutions for building high-performance computing data center networks.
The Advantages of InfiniBand Networks in High Performance Computing Data Centers
Network efficiency: InfiniBand networks offload protocol processing and data movement from CPUs to interconnects, maximizing CPU efficiency and enabling it to quickly process ultra high resolution simulations, large datasets, and highly parallel algorithms. Especially in high-performance computing data centers, significant performance improvements will be achieved, such as Web 2.0, cloud computing, big data, financial services, data centers, and storage applications. This will shorten the time required to complete tasks and reduce the overall cost of the process.
InfiniBand speed: During the period when Ethernet 100G dominated the market, IB network speed was also constantly developing. The Mshine 100G QSFP28 InfiniBand optical module supports advanced transmission protocols, such as Remote Direct Memory Access (RDMA), which can effectively improve the efficiency of high-capacity workload processing. With the ultra-low latency of InfiniBand technology, the Mshine’s 100G QSFP28 Infiniband optical module greatly enhances the interconnection of high-performance computing networks and data centers.
Scalability: With InfiniBand, a network layer 2 containing 48000 nodes can be created in a single subnet. Moreover, the IB network does not rely on broadcast mechanisms such as ARP, so it will not cause a broadcast storm and avoid wasting additional bandwidth.
Conclusion
In short, InfiniBand networks provide strong support for bandwidth upgrades of critical computing nodes by simplifying high-performance network architecture and reducing the latency caused by multi-layer architecture, helping high-performance computing data center users maximize business performance. In the future, InfiniBand networks will become a development trend, widely applied in various fields, providing strong business support for users.
