Highlights
Technology refresh is the primary
driver of data migration.
The following table presents five key factors that show how data migration
software can simplify technology refresh and how Softek

Key factors Description
Performance measurements
Performance
must take into consideration
how quickly data is copied
from the source to target,
and balanced against
network bandwidth and
system overhead.
Roll-back capability If something goes wrong, the
migration can be terminated
and restarted or application
processing can continue on
the source data/device.
In a recent survey, 40 per-
Increase in
volume size cent of migrations involved
an increase in volume size
from the source to the target.
Heterogeneous While host-based prod-
ucts support unlike storage
source and
target hardware devices, most array-based
products require that the
source and target come
from the same vendor.
Application downtime Applications have different
levels of business criticality
and therefore have varying
degrees of acceptable
downtime.
™ ) technology can meet these needs.
Softek TDMF capability
TDMF software includes a throttling
or pacing capability that can speed
up or slow down data movement
depending on system demands in
order to easily balance migration.
Roll back can easily be accom-
plished with TDMF software,
although it can be problematic
with some other technologies,
such as volume managers.
TDMF software can accommo-
date an increase in volume size.
TDMF software is hardware
independent.
TDMF software allows for
nondisruptive data migration so
applications can stay online
and continue to process data
throughout the migration process.
