PowerMax and VMAX All Flash Solutions Design (Local Replication + Remote Replication) Flashcards
(28 cards)
What is TimeFinder SnapVX?
local replication technology that supports VMAX/PMax
What does SnapVX do?
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
How many snapshots can a single volume have?
256
How many target volumes can be linked to the snapshots of a single volume?
1024
What makes the snapshots efficient on PowerMax and VMAX?
made efficient as possible by sharing point-in-time tracks
called snapshot deltas
What is Local Replication Suite?
TimeFinder SnapVX w/ cloud scalable snaps
SnapSure - file level local replication
Compatible Flash - for mainframe
What are the benefits of TimeFinder SnapVX?
shorter create and terminate times w/ no dependency on cache when scaling
zero impact targetless snaps
support for OS and MF environments
underlying technology of zDP
What is SRDF/S?
maintains a synchronous mirrored copy of production data at physically separated system
supports SRDF/CG - for consistency group synchronous replication
What is the distance of SRDF/S?
125m (200km)
What is SRDF/A?
mirrors data from primary while always maintaining a dependent write consistency copy of the data on the secondary
secondary only seconds behind primary copy
What is the distance of SDRF/A?
unlimited distance
What is SRDF/CE?
SRDF/Cluster Enabler
allows Windows Server 20212 running Microsoft Failover Clusters to operate across multiple connected storage arrays in geographically dispursed clusters
What can you run concurrently w/ SRDF/CE?
SRDF/S
SRDF/A
SRDF concurrent
SRDF/ cascaded
What is SRDF/Star?
three site DR solution
secondary site synchronously mirrors data from primary and tertiary site asynchronously mirrors prod data
What are the two types of SRDF/Star?
Cascaded SRDF/Star
Concurrent SRDF/Star
What is SRDF/Metro?
each copy is current and consistent in SRDF/Metro configuration
write conflicts between the paired SRDF devices are managed and resolved
What is the main benefit of SRDF/Metro?
host or host cluster can read and write to both R1 and R2 devices
What is SRDF/AR?
automated remote replication solution
uses both SRDF and TimeFinder to provide long distance restart solution for UNIX and Windows environments
What is a networking option for SRDF/AR?
can be configured to run on lower bandwidth networks
How is SRDF/AR deployed?
over two or three sites
What is FAR w/ SRDF/S?
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
What are the native migration options for PowerMax/VMAX?
SRDF/DM
NDM
ORS
What is SRDF/DM?
SRDF/Data Mobility
enables fast data transfer from R1 to R2 devices over extended distances
How does SRDF/DM work?
uses adaptive copy mode
unlimited distance
