Virtual block device Fibre Channel Protocol (FCP) Dedicated FCP or EDEV Dedicated FCP or EDEV Virtual block device QCOW Not supported Not supported Supported NVMe Not supported Supported Virtual block device 2.1.1.3. Preferred IBM Z system environment The preferred system environment for running OpenShift Container Platform version 4.17 on IBM Z® hardware is as follows: Hardware requirements Three logical partitions (LPARs) that each have the equivalent of six Integrated Facilities for Linux (IFLs), which are SMT2 enabled, for each cluster. Two network connections to both connect to the LoadBalancer service and to serve data for traffic outside the cluster. HiperSockets that are attached to a node directly as a device. To directly connect HiperSockets to a node, you must set up a gateway to the external network via a RHEL 8 guest to bridge to the HiperSockets network. When installing in a z/VM environment, you can also bridge HiperSockets with one z/VM VSWITCH to be transparent to the z/VM guest. IBM Z operating system requirementsTable 2.7. Operating system requirements z/VM [1]LPARRHEL KVM Hypervisor One instance of z/VM 7.2 or later IBM® z14 or later with DPM or PR/S One LPAR running on RHEL 8.6 or later with KVM, which is managed by libvirt OpenShift Container Platform control plane machines Three guest virtual machines Three LPARs Three guest virtual machines OpenShift Container Platform compute machines Six guest virtual machines Six LPARs Six guest virtual machines Temporary OpenShift Container Platform bootstrap machine One machine One machine One machine To ensure the availability of integral components in an overcommitted environment, increase the priority of the control plane by using the CP command SET SHARE. Do the same for infrastructure nodes, if they exist. See SET SHARE (IBM® Documentation). 2.1.1.4. Certificate signing requests management Because your cluster has limited access to automatic machine management when you use infrastructure that you provision, you must provide a mechanism for approving cluster certificate signing requests (CSRs) after installation. The kube-controller-manager only approves the kubelet client CSRs.
