'HB' sub-family storage optimized VM size series

Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets

The 'HB' sub-family of VM size series are one of Azure's high-performance computing (HPC) optimized H-family VM instances. They're designed for compute-intensive workloads, such as computational fluid dynamics, finite element analysis, and large-scale scientific simulations. HB-series VMs, equipped with high-performance AMD EPYC processors and fast memory, deliver exceptional CPU and memory bandwidth. They're ideal for applications that need extensive computational resources to handle large-scale calculations and data processing. They're well-suited for industries such as engineering, scientific research, and data analysis. In these fields, processing speed and accuracy are essential for maintaining productivity and driving innovation.

Workloads and use cases

Computational Fluid Dynamics (CFD): HB family VMs are ideal for simulations in fields like aerospace, automotive design, and manufacturing, where fluid dynamics calculations are intensive.

Finite Element Analysis (FEA): HB family VMs are suitable for engineering analyses that simulate physical phenomena, requiring intensive computational power to model complex systems and materials.

Weather Forecasting: HB family VMs can handle the massive datasets and complex simulations required for high-resolution weather modeling and forecasting.

Seismic Processing: HB family VMs are in the oil and gas industry, HB family VMs can process seismic data to help map and understand subsurface structures.

Scientific Research: HB family VMs support a wide range of scientific research that requires large-scale mathematical modeling, including physics and computational chemistry simulations.

Genomics and Bioinformatics: HB family VMs are also used in life sciences for genomic analysis, where large amounts of data need to be processed quickly to decode genetic information.

Series in family

HBv3-series

HBv3-series Virtual Machines (VMs) are designed for very demanding computing tasks. They help with things like studying how liquids move, analyzing structures, predicting weather, and processing earthquake data. They also support oil reservoir modeling and testing computer chip designs. HBv3 VMs feature up to 120 AMD EPYC™ 7V73X (Milan-X) CPU cores, 448 GB of RAM, and no simultaneous multithreading. HBv3-series VMs also provide 350 GB/sec of memory bandwidth (amplified up to 630 GB/s), up to 96 MB of L3 cache per core (1536 MB total per VM), up to 7 GB/s of block device SSD performance, and clock frequencies up to 3.5 GHz. All HBv3-series VMs feature 200 Gb/sec High Data Rate (HDR) InfiniBand from NVIDIA Networking to enable supercomputer-scale Message Pass Interface (MPI) workloads. These VMs are connected in a nonblocking fat tree for optimized and consistent RDMA performance. The HDR InfiniBand fabric also supports Adaptive Routing and Dynamic Connected Transport (DCT), along with standard Reliable Connection (RC) and Unreliable Datagram (UD) transports. These features improve performance, make scaling easier, and keep results consistent.
