Hardware requirements

Table: Hardware requirements

Requirement

Description

Memory (Operating System)

Minimum 24 GB

CPU (on Kubernetes)

On Physical servers - a minimum of 2 processors with 6/8 cores each.

On Virtual machines (VMware-like environment) - a minimum of 4 vCPUs.

CPU (on OpenShift)

On Physical servers - a minimum of 2 processors with 6/8 cores each.

On Virtual machines (VMware-like environment) - a minimum of 12 vCPUs for master node and 8 vCPUs for worker nodes.

Node

All nodes in a Cluster must have the same operating system version.

Storage

Storage can be one or more shared disks, or a disk array connected either directly to the nodes of the cluster or through a Fibre Channel Switch. Nodes can also have non-shared or local devices on a local I/O channel.

In a Flexible Storage Sharing (FSS) environment, shared storage may not be required.

Cluster platforms

There are several hardware platforms that can function as nodes in a Arctera InfoScale™ cluster.

For the InfoScale cluster to work correctly, all nodes must have the same time. If you are not running the Network Time Protocol (NTP) daemon, ensure the time on all the systems comprising your cluster is synchronized.

SAS or FCoE

Each node in the cluster must have an SAS or FCoE I/O channel to access shared storage devices. The primary components of the SAS or Fibre Channel over Ethernet (FCoE) fabric are the switches and HBAs.
