Hardware requirements
Note: These requirements are for a basic cluster configuration. Depending on your workloads/applications, higher values might be required.

| 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. |
