Q

What does SnapVX do?

A

creates local snapshots without requiring a pairing between the source and target volumes

targets are not required to create the snapshot and are only required to mount and use a replica

Q

What is SRDF/Metro?

A

each copy is current and consistent in SRDF/Metro configuration

write conflicts between the paired SRDF devices are managed and resolved

17
Q

What is the main benefit of SRDF/Metro?

A

host or host cluster can read and write to both R1 and R2 devices

18
Q

What is SRDF/AR?

A

automated remote replication solution

uses both SRDF and TimeFinder to provide long distance restart solution for UNIX and Windows environments

19
Q

What is a networking option for SRDF/AR?

A

can be configured to run on lower bandwidth networks

20
Q

How is SRDF/AR deployed?

A

over two or three sites

21
Q

What is FAR w/ SRDF/S?

A

FAR = file auto recovery

FAR enables you to manually fail over or move a Virtual Data Mover (VDM) from a source eNAS system to destination eNAS system

22
Q

What are the native migration options for PowerMax/VMAX?

A

SRDF/DM
NDM
ORS

23
Q

What is SRDF/DM?

A

SRDF/Data Mobility

enables fast data transfer from R1 to R2 devices over extended distances

24
Q

How does SRDF/DM work?

A

uses adaptive copy mode

unlimited distance

25
Q

What is NDM?

A

Non-Disruptive Migration

method for migrating data without application downtime

26
Q

When do you typically use NDM?

A

migrations typically performed between arrays within the same data center

to consolidate multiple older arrays into a smaller footprint

27
Q

What is ORS?

A

open system replicator

enables copying full or incremental copies of data from qualified third-party arrays within a SAN infrastructure to PMax/VMAX

28
Q

How does ORS work?

A

pull from source volumes on qualified remote arrays to volume

perform online data migration
