1. A software-Redundant Array of Independent Disk (RAID)-protected boot data virtual Storage Area Network (vSAN) system, comprising:
a chassis;
a plurality of storage devices that are housed in the chassis;
a first controller device and a second controller device that are coupled to the plurality of storage devices; and
a software Redundant Array of Independent Disk (RAID) subsystem that is housed in the chassis, and that is coupled to the plurality of storage devices, to the first controller device and to the second controller device, wherein the software RAID subsystem is configured to:
select the first controller device as a dedicated RAID controller device and the second controller device as a dedicated virtual Storage Area Network (vSAN) controller device;
configure a first subset of the plurality of storage devices for boot storage and a second subset of the plurality of storage devices for vSAN storage;
provide a RAID path from the dedicated RAID controller device to the boot storage provided by the first subset of the plurality of storage devices;
provide a vSAN path from the dedicated vSAN controller device to the vSAN storage provided by the second subset of the plurality of storage devices;
route boot storage commands along the RAID path to the second subset of the plurality of storage devices using the dedicated RAID controller device; and
route vSAN storage commands along the vSAN path to the first subset of the plurality of storage devices using the dedicated vSAN controller device.
