I/O fencing support for virtual-to-virtual clustering
Disk-based SCSI-3 I/O fencing is supported for VCS clusters across guest VMs on different physical hosts. In case of VM as iSCSI initiator, VMs can be on the same or on different physical hosts. The following table lists the SCSI-3 fencing support for various Linux virtualization technologies.
Table: I/O fencing support matrix for virtual-to-virtual clustering
Virtualization technology-Storage protocol | SCSI initiator | Guest OS | Clustering support |
|---|---|---|---|
KVM-iSCSI | VM as Initiator | RHEL 8.x RHEL 9.x SLES 15 | Yes |
KVM-iSCSI | Hypervisor as Initiator (Virtio-SCSI) | RHEL 8.x RHEL 9.x SLES 15 | Yes |
VMware-iSCSI | VM as Initiator | RHEL 8.x RHEL 9.x SLES 15 | Yes |
VMware-iSCSI | Hypervisor as Initiator (RDMP) | RHEL 8.x RHEL 9.x SLES 15 | Yes |
KVM-FCP | VM as Initiator (PCI - Passthrough) | RHEL 8.x RHEL 9.x SLES 15 | No |
KVM-FCP | Hypervisor as Initiator (Virtio-SCSI) | RHEL 8.x RHEL 9.x SLES 15 | No |
VMware-FCP | VM as Initiator | RHEL 8.x RHEL 9.x SLES 15 | Yes |
VMware-FCP | Hypervisor as Initiator (RDMP) | RHEL 8.x RHEL 9.x SLES 15 | Yes |
