In the Huawei Cloud Stack solution, CSBS & VBS services can be deployed to support volume or host backup. When OceanStor5500V3/V5 is selected as the backup storage, which of the following analyses of the backup storage planning is correct?
A . The two network ports of the 10GE network cards on the two controllers need to be bound separately, and the two network ports need to be bound to different drift groups to provide backup services.
B . Each disk domain can create a storage pool. The RAID6 strategy can be flexibly configured, with a maximum of 26D+2P.
C . A single disk domain cannot have more than 48 disks, and the disks in the same disk domain should come from different engines as much as possible.
D . eBackup has no limit on the size of the file system. Each storage pool needs to create multiple file systems to be assigned to the backup server.

Answer: B
