This article is intended for administrators wishing to leverage SvHCI in a system without hardware RAID controllers. This example leverages a server with 2x 3.84TB M.2 NVMe SSDs to create hypervisor and VM storage on a resilient boot software RAID1.
Software RAID1 Deployment
This guide explains how to deploy SvHCI using a resilient software RAID1 boot configuration on systems without a hardware RAID controller.
Summary
SvHCI combines virtualization and shared storage, in a single installable ISO image that is deployed to hardware to enable VM Failover, live migrate, snapshot and clustering.
SvHCI enables a bootable software RAID1 configuration enabling a simple resilient, having cross node resiliency (Replication Factor 2 of the VM disks) and internal node resiliency through the software RAID1, architecture with small footprint systems, per the below:
Software RAID1 architecture overview
Boot Software RAID1 Installation
During a standard installation workflow:
To enable software RAID options, type raid per the below:
Enable software RAID during installation
With this selected we now have the ability, per the below, to configure a software boot RAID1 and deploy to this md0 device:
Configure the boot RAID1 device
Once up and installed this will present in the GUI per the below:
