A.RAID 6 requires two-level parity.

B.Frequently used RAID 6 technologies include RAID 6 P+Q and RAID 6 DP.

C.RAID 6 requires at least three member disks.

D.RAID 6 can recover data after two member disks fail.

A.DAS storage space can be fully utilized, storage devices that can be shared by different application servers, fully Leverage idle storage space

B.DAS refers to the storage device is directly connected to the server through a SCSI cable or Fibre Channel

C.The data in DAS mode is still scattered, and each application has a set of storage devices. Management is decentralized and cannot be centralized

D.When the server and the storage device are directly connected, new application requirements arise, only for the newly added server Separate storage device configuration, resulting in repeated investment
