−
M.2 SSDs are supported for RAID 0/1 and hot swap
without opening the chassis cover is supported
when the server is configured with an Avago
SAS3004iMR RAID controller card.
−
The drive letter of the M.2 SSDs managed by the
Avago SAS3004iMR RAID controller card can be
set to
sda by modifying the GRUB parameters only
when the RAID controller card is used with a
SmartRAID 3152-8i or SmartHBA 2100-8i RAID
controller card.
NOTE
⚫
The M.2 SSD module is used only as the boot device when
the OS is installed. 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
https://kb.vmware.com/s/article/1033696 .
⚫ Configure syslog. For details, see
https://kb.vmware.com/s/article/2003322 .
⚫ The M.2 SSD cannot be used to store data due to poor
endurance. In write-intensive applications, the M.2 SSD will
wear out in a short time.
Use enterprise-level high endurance (HE) SSDs or HDDs for
data storage.
⚫ The M.2 SSD is not recommended for write-intensive service
software due to poor endurance.
