Ace Your H13-611 HCIA Storage Exam

A storage device connects to a host using the SCSI-based bus architecture.

DAS is unfavorable to storage resource sharing,

The host CPU has a work load when storing data.

Long-distance transmission is supported between a host and a storage device.

RAID 10 is used in scenarios with high requirements for speed and fault tolerance

RAID 10 requires at least 4 member disks

In RAID 10, if two member disks in a subgroup fail, the data is read normally

In RAID 10, the data is first mirrored and then striped

A logical volume can reside on multiple physical disks. Data storage can be physically discontinuous.

A volume group is built on physical volumes. A volume group can contain one physical volume group or multiple physical volumes.

Physical volumes reside on the lowest layer in the logical volume manager. Logical volumes and volume groups are dependent on physical volumes.

Multiple volume groups can be created on the space of a logical volume.

Mainframe servers improve performance.

Virtualization technology improves resource utilization.

Distributed computing and storage improve reliability.

Unified resource management improves efficiency.
