Step 2: Create a new HPC Pack cluster

This article describes how to create a new HPC Pack cluster. You may choose one of the following three availability options for your cluster:

• Single head node cluster: The HPC Pack cluster is created with a single head node node. Note, you will not be able to migrate it to a high availability cluster later by adding a new head node.
• High availability(HA) cluster with built-in HA architecture: The HPC Pack cluster is created as a high availability cluster with the built-in high availability architecture newly introduced in HPC Pack 2019.
• High availability(HA) cluster with Microsoft Service Fabric: The HPC Pack cluster is created as a high availability cluster with Microsoft Service Fabric introduced in HPC Pack 2016.

Before installation

To deploy the head node of your HPC cluster, you must install a supported edition of Windows Server 2019, Windows Server 2016 or Windows Server 2012 R2 on the computer (or computers) that will act as the head node, and join the computer (or computers) to an Active Directory domain. For more information about the system requirements to install HPC Pack on the head node, see System Requirements for Microsoft HPC Pack 2019.

More considerations for the installation

• Before you install the operating system, you should obtain and install the latest BIOS, firmware, and device drivers for your head node computer from the websites of your hardware vendors.
• We strongly recommend that you perform a clean installation of Windows Server before installing HPC Pack. If you want to install HPC Pack on an existing installation of Windows Server, remove all server roles first, and then follow the procedures in this guide. For procedures to remove role services and server roles by using the Server Manager GUI or command-line tools, see Install or Uninstall Roles, Role Services, or Features. HPC Pack cannot be installed on the head node computer if the Deployment Server role service of the Deployment Services role is already installed.
• Windows Server must be installed in one of the following languages that is supported by HPC Pack on the head node: English, Japanese, or Simplified Chinese.
• Ensure that the Windows Firewall service is running on the head node. This is necessary so that HPC-specific firewall rules for an HPC cluster can be applied during and after installation of HPC Pack. By default in Windows Server 2019, Windows Server 2016 and Windows Server 2012 R2, the Windows Firewall service is running.

Option 1: Create a single head node cluster

1. To start the HPC Pack Installation Wizard on the computer that will act as the head node, run Setup.exe from the HPC Pack installation package in a local folder.
