Storage Supports a variety of drive congurations. For details,
see 5.5.1 Drive Congurations.
● Supports two M.2 SSDs.
– M.2 SSDs are supported only when the server is
congured 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.
●
Congure 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.
● Do not use the M.2 SSD as the cache.
● Supports hot swap of SAS/SATA drives.
● Supports a variety of RAID controller cards. Use the
Computing Product Compatibility Checker to
obtain information about the
specic RAID
controller cards supported.
– The RAID controller card supports RAID
conguration, RAID level migration, and drive
roaming.
– The PCIe RAID controller card occupies one
standard PCIe slot.
For details about the RAID controller card, see
Huawei V5 Server RAID Controller Card User
Guide.
● Supports a SAS RAID controller card (with a 1 GB, 2
GB, or 4 GB cache) and a supercapacitor (providing
