Minimum system requirements

Verify that the Ops Center Administrator server meets or exceeds the minimum requirements to take advantage of all the Ops Center Administrator features.

Minimum system requirements (Docker and Podman)

Server	Minimum requirements
Hypervisor operating system	VMware^® ESXi 7.0 or higher, Microsoft Hyper-V, Linux KVM Note: Use the product installers when running Hyper-V or KVM. Only VMware supports OVA installations.
Container runtime version for installation from tar file	Docker Version 18 (minimum supported – v18.09.6) Version 19 (minimum supported – v19.03.0) Version 20 (minimum supported – v20.10.5) Podman Version 3.3.`x`, 3.4.`x`, 4.0.`x`, 4.1.`x`, 4.2.`x`, and 4.4.`x`.
Operating system for installation from tar file Linux	Docker Red Hat Enterprise Linux 7.x and Oracle Linux 7.x Podman Red Hat Enterprise Linux 8.1, 8.2, 8.4, 8.6, 8.8, and 9.2 Oracle Linux 8.1, 8.2, 8.4, 8.6, 8.8, and 9.2 For details on specific supported versions of Linux, see the Compatibility matrix. Note: Supported versions of Podman dependent libraries are: containers-common For Podman 3.3.`x`, 3.4.`x`, 4.0.`x`, and 4.1.`x`: 1-3 to 1-39 For Podman 4.2.`x` and 4.4.`x`: 1-27 to 1-64 (RHEL/OL 8.x), 1-27 to 1-52 (RHEL/OL 9.x) conmon 2.0.29 or later runc (only required for RHEL/OL 8.x) 1.0.0-74 or later
Access for installation from tar file	Root user
Recommended drive type	SSD or a higher performance drive type
Available disk space	80 GiB under the Docker root directory (default directory: /var/lib/docker) 80 GiB under the Podman root directory (default directory: /var/lib/containers) In addition, a total of 10 GiB temporary, available space is required for installation using the application installer. This consists of 10 GiB under /var/tmp.
Memory	The required RAM and swap memories are determined according to the system requirements based on system scale. Small scale: 8 GiB (RAM) and 3 GiB (Swap) Medium scale: 10 GiB (RAM) and 3 GiB (Swap) Large scale: 10 GiB (RAM) and 3 GiB (Swap) Note: Because more swap memory is used instead of physical memory compared to earlier versions, the response of some APIs and graphical user interfaces can be slower immediately after installation or when you perform an operation that you have not used for a long time. To improve performance, we recommend applying the following memory settings: Small scale: 11 GiB (RAM) Medium scale: 12 GiB (RAM) Large scale: 13 GiB (RAM) Note: Ops Center Administrator v10.9.1 and later can manage a large number of resources, such as number of storage systems or volumes, with the fixed memory size. If you upgrade from a previous version to v10.9.1 or later, any changes that you made to the memory settings by using the following commands are automatically updated to the required settings: elasticsearch-memory-setting rainier-memory-setting
CPU	4 vCPUs
A client computer that can run a supported browser	One of the following: Google Chrome (latest version of the stable channel) Firefox ESR 102.0 or later Microsoft Edge (latest version of the stable channel). Internet Explorer mode and Microsoft Edge for Linux are not supported. Note: The above listed browsers are supported by Ops Center Administrator. If you want to launch another management tool from Ops Center Administrator, verify the support browsers of required management tool.
