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

Technology refresh is the primary
