![]() If you are NOT using vSAN, boot and data volumes can share a VMD Domain.RAID1 data volume with VMD 2.8 driver or newer.RAID1 boot volume (ESXi redundant boot).When configuring RAID1 for vSphere there are a few supported options. Intel VMD-UEFI drivers loaded into BIOS.Intel generation 1-4 Intel Xeon Scalable Processors.This reduces the risk of unqualified HW or delays in qualified HW. With the Intel VMD HW built into the Xeon CPUs, no additional HBAs are required. Conservation of PCIe lanes for vSphere Datastores or VMware vSAN devices.Some of the standardized boot options enabled for VMware deployments include: This functionality can also reduce PSODs while providing a better experience with NVMe. ESXi only sees a single target, the RAID is managed behind the scenes. With the optional PCH VMD domain, the boot volume doesn’t consume PCIe lanes. The new RAID1 capability allows for a redundant OS providing high availability by providing pre-OS RAID configuration at the OEM platform level. The Intel-enabled NVMe driver for vSphere now supports RAID 1 volumes for boot and data. Features such as Hot Plug, LED management, and error handling are some of the features available. Intel VMD is similar to an HBA controller but for NVMe SSDs. Intel Volume Management Device (VMD) works with the Xeon family of processors to enable additional control and management of NVMe devices. ![]() Intel VMD enabled NVMe driver for VMware ESXi with RAID1.
