SSDs when the server is configured with an M.2
SSD adapter card.
● The M.2 SSD is used only as a boot device for installing
the OS. Small-capacity (32 GB or 64 GB) M.2 SSDs do
not support logging due to poor endurance. If a small-
capacity M.2 SSD is used as the boot device, a
dedicated log drive or log server is required for logging.
For example, you can dump VMware logs in either of the
following ways:
● Redirect /scratch. For details, see
kb.vmware.com/s/article/1033696.
● Configure syslog. For details, see
kb.vmware.com/s/article/2003322.
● The M.2 SSD cannot be used to store service data due to
poor endurance. In write-intensive applications, the M.2
SSD will wear out in a short time.
If you want to use SSDs or HDDs as data storage
devices, use enterprise-level SSDs or HDDs with high
DWPD.
● The M.2 SSD is not recommended for write-intensive
service software due to poor endurance.
● Do not use M.2 SSDs for cache.
When NVMe/E1.S drives are configured:
● Before using the VMD function, contact technical support
engineers of the OS vendor to check whether the OS
supports the VMD function. If yes, check whether the
VMD driver needs to be manually installed and check the
installation method.
● When the VMD function is enabled and the latest VMD
driver is installed, surprise hot swap is supported.
● When the VMD function is disabled, orderly hot swap is
supported.
