Module 10: Data Protection (Data Migration) Flashcards
What is data migration?
specialized replication technique that enables moving data from one system to another
What is VM migration?
VMs are moved from one physical compute system to another without downtime
What are the advantages of VM migration?
schedule maintenance without downtime
VM load balancing
What is VM storage migration?

What are the advantages of VM storage migration?
simplifies array migration/storage upgrades
dynamically optimizes storage IO
efficiently manages storage capacity
What is SAN based migration?
moves block level data between heterogenous storage systems over SAN
What is the storage system called that does the migration in SAN based migration?
control storage system
What is the storage system called that receives the migration in SAN based migration?
remote storage system
What is NAS based migration?
moves file level data between NAS systems over LAN and WAN
What is appliance based data migration?
virtualization appliance facilitates the movement of files from an old NAS to new
What is the advantage of appliance based data migration?
while files are being moved clients can access their files nondisruptively
What does a virtualization appliance do in data migration?
creates a virtualization layer that eliminates the dependencies between data that is accessed at the file level and location where files are physically stored
