Host-based mirroring uses IP which can be less reliable than F

C.  

C.  

multiMirror uses the reliability of the RAID devices to accomplish a much more reliable copy.

D.  

Snapshot-enabled mirroring allows multiMirror to retain several recovery points at the remote site for rollback purposes.

A.  

lack of snapshot technology

B.  

lack of non-disrupting data migration

C.  

only runs on director-level switches

D.  

lack of full volume, point-in-time, mirror-based images

E.

A.  

Synchronous SnapMirror

B.

A.  

Pooling the storage into a server virtualization model whereby different servers can emulate hosts and tier the data.

B.  

Pooling the storage into a networked virtualization model zoning the virtualized storage utilizing third-party tools.

C.  

Pooling the storage across different vendor’s storage arrays into a centralized pool and then assigning different applications and tiers to different pools.

D.  

Pooling the storage across different vendor’s storage arrays into assigned volume groups and use virtual servers to tier the data.

A.  

multiView can be used to take a PiT copy. Additional PiTs can then be taken off the first PiT for test and development.

B.  

multiCopy can be used to copy the database to another storage array. multiView can then be used to take low capacity PiTs of the copy for test and development.

C.  

multiCopy will create a steady stream of data to a copy area. multiView can then be used to take PiTs whenever they are required for test and development.

D.  

MultiView can be set to only read the PiT data when the volume is not in use. Requests for PiTs for test and development can therefore be queued.

A.  

by keeping the servers from running out of space

B.  

by spreading the workload across controllers

C.  

by moving the workload to the DPMs

D.  

by sharing allocated but unused capacity across volumes sharing a pool

A.

B.  

(yearly revenue) divided by (number of employees multiplied by the number of business hours in a day)

C.  

(yearly revenue) divided by (duration of outage multiplied by employee hourly wage)

D.

B.  

Their virtual volume structure will remain the same.

C.  

VMware takes the physical resources, pools them and then assign resources as needed to the applications, just like SVM.

D.  

Their existing snapshot-based backup process will continue to work.
