What You Will Learn
Storage administrators striving to implement fast, trouble-free data migration face significant challenges. Host-,
array-, and appliance-based solutions tend to be expensive, intrusive options. Migrating data through the SAN fabric
is a faster, easier, and more cost-effective alternative with significant benefits:
array-, and appliance-based solutions tend to be expensive, intrusive options. Migrating data through the SAN fabric
is a faster, easier, and more cost-effective alternative with significant benefits:
●
Reduces service disruption
●
Transparently supports heterogeneous environments
●
Speeds migration
●
Reduces costs
●
Eases management

Data Mobility Manager (DMM) for the Cisco MDS 9000 Family is a SAN fabric-based solution that helps
administrators migrate data quickly and efficiently, using best practices.
Challenge
Data growth, equipment end-of-life (EOL), and increasing support costs have an often expensive common
denominator: data migration. The cost of such migration is significant: customers traditionally average US$200,000
per year on data migration services.
denominator: data migration. The cost of such migration is significant: customers traditionally average US$200,000
per year on data migration services.
In addition to the expense, migration can present substantial business and technical challenges. Administrators
striving to limit the effects on business operations must coordinate outage time with users and keep the amount of
time needed for the migration as short as possible. Planning is critical and also complex because it must address the
needs of multiple teams in separate departments. A variety of tools, frequently nonstandard, are often required to
move data between arrays from different vendors or to newer equipment. A multifaceted tool environment means
greater opportunities for error, which can undermine the best efforts of administrators to achieve a smooth migration
process.

process.
Traditional migration solutions do little to address these challenges. Host-based tools can reduce the performance of
other business applications by consuming CPU cycles and I/O bandwidth. Array-based solutions either do not
support heterogeneous storage environments, or offer a one-way transfer that locks customers into a single-vendor
solution. Appliance-based solutions require a service technician to enter the data center, install the appliance in the
data path between the host and the storage device, and then remove the appliance after performing the migration.
The result is an expensive, intrusive approach that is not readily scalable and requires downtime before and after the
migration.

To efficiently meet ongoing migration needs, storage administrators need a simpler, less disruptive, and more cost-
effective way to migrate data between heterogeneous storage arrays.
