Instance Family


An instance is a purchased BMS. Different instance types provide varied computing capabilities, storage space, and network performance. You can select a type that meets your service requirements. After you purchase a BMS, you can perform operations such as starting, stopping, and in-band monitoring.

BMS Types

A BMS has x86 or Kunpeng CPUs. Huawei-developed high-performance physical servers with exclusive optimization algorithms provide a reliable hardware environment for all the BMSs.


  • If a BMS uses local disks, its system disk is configured as RAID 1 and cannot be changed. The data disks are configured as RAID 0. To change the RAID configuration of data disks, contact the operation administrator.
