NVMe optimization & baremetal to ESXi report
USE NVMe AS VIRTUAL DISK / HOW TO LIMIT DSM TO SPECIFIC DRIVES
NOTE: if you just want to use NVMe drives as cache and can't get them to work on DSM 6.2.x, go here.
Just thought to share some of the performance I'm seeing after converting from baremetal to ESXi in order to use NVMe SSDs.
My hardware: SuperMicro X11SSH-F with E3-1230V6, 32GB RAM, Mellanox 10GBe, 8-bay hotplug chassis, with 2x WD Red 2TB (sda/sdb) in RAID1 as /volume1 and 6x WD Red 4TB (sdc-sdh) in RAID10 as /volume2
USING PHYSICAL RDM TO ENABLE NVMe (or any other ESXi accessible disk device) AS REGULAR DSM DISK
Summary:
Heretofore, XPEnology DSM under ESXi using virtual disks is unable to retrieve SMART information from those disks. Disks connected to passthrough controllers work, however.
NVMe SSDs are now verified to work with XPEnology using ESXi physical Raw Device Mapping (RDM). pRDM allows the guest to directly read/write to the device, while still virtualizing the contro
