Eav4-series sizes are based on the 2.35Ghz AMD EPYC<sup>TM</sup> 7452 processor that can achieve a boosted maximum frequency of 3.35GHz. The Eav4-series sizes are ideal for memory-intensive enterprise applications. Data disk storage is billed separately from virtual machines. To use premium SSD, use the Easv4-series sizes. The pricing and billing meters for Easv4 sizes are the same as the Eav3-series.

HC-series VMs are optimized for applications driven by dense computation, such as implicit finite element analysis, molecular dynamics, and computational chemistry. HC VMs feature 44 Intel Xeon Platinum 8168 processor cores, 8 GB of RAM per CPU core, and no hyperthreading. The Intel Xeon Platinum platform supports Intel’s rich ecosystem of software tools such as the Intel Math Kernel Library and advanced vector processing capabilities such as AVX-512.

HC-series VMs feature 100 Gb/sec Mellanox EDR InfiniBand. These VMs are connected in a non-blocking fat tree for optimized and consistent RDMA performance. These VMs support Adaptive Routing and the Dynamic Connected Transport (DCT, in additional to standard RC and UD transports). These features enhance application performance, scalability, and consistency, and their usage is recommended.
