Term
What EMC Control Center product allows the customer to configure Symmetrix units as BCVs?
Definition
Symmetrix Manager or Solutions Enabler commands.
Term
What size must a BCV be in TimeFinder?
Definition
The same size and type as the device which it will mirror.
Term
Using TimeFinder, what is the default and maximum number of BCVs that can be paired with the same STD device?
Definition
8 (default)
16, using the SYMCLI_MAX_BCV_PAIRS command
Term
What TimeFinder Operation is used to synchronize the standard volume to the BCV volume?
Definition
Full or Inc (default) Establish
Term
What TimeFinder Operation is used to synchronize contents of BCV volume to the standard volume?
Definition
Full or Inc (default) Restore
Term
What TimeFinder Operation is used to terminate a mirror relationship between a BCV and a standard volume?
Definition
Diff Split
Reverse Split
Instant Split (default)
Consistant Split
Term
What TimeFinder Operation is used to provide the current status of BCV/standard volume pairs?
Definition
Verify
Term
True or False? In TimeFinder, a new BCV is instantly available to the host?
Definition
False. It must first be fully established, which takes some time, and then split in order for the host to access it.
Term
What TimeFinder Operation will overwrite the newly synchronized production data on the BCV with the original data from its mirror?
Definition
Reverse Split
Term
What does ECA stand for and what does it do?
Definition
Enginuity Consistancy Assist
It can hold I/O at the Symmetrix level -- eliminating the need for PowerPath when TimeFinder performs a split operation.
Term
What TimeFinder Operation is used to write the changes that have occurred on a BCV to the production volume?
Definition
Incremental Restore
Term
What do the following add-on TimeFinder products represent?

TimeFinder/CG
TimeFinder/EIM
TimeFinder/SIM
Definition
TimeFinder/CG (Consistancy Groups)
TimeFinder/EIM (Exchange Integration)
TimeFinder/SIM (SQL Integration)
Term
What are the benefits of TimeFinder/Mirror and TimeFinder/Mirror Clones?
Definition
Answer
Term
What are concurrent BCVs?
Definition
Concurrent BCVs is a TimeFinder/Mirror - BCV feature that allows two BCVs to be simultaneously established with a Standard volume.
Term
How does a TimeFinder/Clone handle reads and writes?
Definition
TimeFinder/Clone use a copy on access method. Data is copied to the target device the first time a track on the source device is written to or a track on the target is accessed (read or write).
Term
True or False. A TimeFinder/Clone is available instantly.
Definition
True. A TimeFinder/Close uses a copy on access method.
Term
What are some benefits of TimeFinder/SNAPs?
Definition
- Reduces Disk Space required for Mirrored Copy
- Copy-on-write technique to conserve disk space (writes written to the "Save Area" which is usally 20% of source volume)
- Are instantly available
Term
How does EMC accomplish TimeFinder Snapshot Consistency?
Definition
ECA temporarily halts I/O from host, snapshots are activated and I/O resumes without application implact. Devices are consistant and re-startable as a set.
Term
Where can you restore data to with TimeFinder/Snap?
Definition
Can retore directly to:
The source volume
A split BCV of source
A separate volume
Term
What EMC Product is used to
- Discover replication environments
- Automate replication process
- Integrate replication technologies at the application level
Definition
EMC Replication Manager
Term
What is a limitation of using a TimeFinder composite group?
Definition
Control operations can only be performed on the group as a whole.
Term
What is the name of optional TimeFinder service that provides you with the ability to store decice and composite group definitions in a shared repository located on each Symmetrix array, which would then automatically become visible to all attached hosts.
Definition
Group Name Services
Term
What device does a TimeFinder Clone use for establishing a mirror relationship?
Definition
Standard Volume / BCV
Term
Which TimeFinder utility allows conserving disk space and creation of a point-in-time copy of data?
Definition
Snap
Term
Which TimeFinder utlity allows creating a point-in-time copy of production data without BCV devices?
Definition
Clone
Term
Which tool uses a Graphical User Interface to automate replications?
Definition
EMC Replication Manager - ERM
Term
What action should be taken before performing a normal split of a BCV pair?
Definition
Quiesce the I/O to the standard volume.
Term
Fill in the blank for EMC Snap:
- Reduces ______ required for mirrored copy
- COFW conserves ______
- non-disruptive, ______ resync and business processes by enabling parallel processing
- mirrored copy within source symm.
Definition
- Reduces disk space required for mirrored copy
- COFW conserves disk space
- non-disruptive, incremental resync and business processes by enabling parallel processing
- mirrored copy within source symm.
