Supported machine series for Cluster Director

This document describes the CPU-based machines and GPU-accelerated machines that are available in Cluster Director. You use these machines to deploy and manage the underlying infrastructure to run high performance computing (HPC), artificial intelligence (AI), or machine learning (ML) workloads.

CPU-based machines

Cluster Director supports general-purpose machine series, which are primarily CPU-based and suitable for HPC workloads and cluster management roles, such as login nodes.

N2 machine series

Cluster Director supports the N2 machine series. This series offers a balance of price and performance suitable for a variety of workloads, such as CPU-bound computational tasks or general-purpose HPC workloads.

The N2 machine types are differentiated by the amount of memory configured per vCPU. These memory configurations are as follows:

  • standard: 4 GB of system memory per vCPU

  • highmem: 8 GB of system memory per vCPU

  • highcpu: 1 GB of system memory per vCPU

Each family offers a range of machine sizes, from 2 to 128 vCPUs. For login nodes, you can only use N2 standard machine types with 32 or fewer vCPUs. Otherwise, you can use any N2 machine type. The following table summarizes the available N2 machine types in Cluster Director:

N2 standard

n2-standard-32 32 128 Up to 32 Up to 50
n2-standard-48 48 192 Up to 32 Up to 50
n2-standard-64 64 256 Up to 32 Up to 75
n2-standard-80 80 320 Up to 32 Up to 100
n2-standard-96 96 384 Up to 32 Up to 100
n2-standard-128 128 512 Up to 32 Up to 100

* A vCPU is implemented as a single hardware thread, or logical core, on one of the available CPU platforms.
‡ Maximum egress bandwidth cannot exceed the number given. Actual egress bandwidth depends on the destination IP address and other factors. For more information, see Network bandwidth.
# Supports high-bandwidth networking for larger machine types. For Windows OS images, the maximum network bandwidth is limited to 50 Gbps.
