Providing industry-leading data mobility

software for the mainframe

You need a standard, repeatable data

mobility strategy that can mitigate oper-

ational risk without affecting application

performance and service level agree-

ments. You also need to satisfy your

application availability requirements.

The IBM Migration Services for data –

Softek® TDMF™ (Transparent Data

Migration Facility) z/OS offering is an

industry-leading, host-based software

solution for data migration. Designed

for data centers with multiple system

images and the need for continuous

application availability, the Softek

TDMF z/OS solution from IBM pro-

vides local or global migration—with

no downtime required.

Enabling nondisruptive Dynamic Swap

The Softek TDMF z/OS offering has a

Dynamic Swap capability that performs

data migrations without disruption to the

applications by transparently directing

input/output (I/O) between source and

target storage. That means that applica-

tion availability is maintained beyond

the migration phase through the swap

to the new storage. This swap can be

automated so that no manual interven-

tion is required.

Migrating data with flexible pacing

options

Flexible pacing options help main-

tain application performance levels

throughout the migration process—

The Softek TDMF z/OS solution enables a simple, unified approach to nondisruptive movement of data across storage vendor platforms and operating environments.

even during busy periods—so you can

perform your migration processes during

normal business hours.

Copying at full speed

When speed is of the essence, the

Full-Speed Copy feature allows you to

perform a volume migration using two

I/O buffers, with overlapping read and

write operations, supporting faster per-

formance. Pacing is a standard part of

this feature.

Streamlining data movement

The Active-In-Copy feature enables

the movement of large amounts of data

without having to set up multiple small

groups or sessions.

Simplifying migration sessions

The Softek TDMF Session Assistant fea-

ture is an Interactive System Productivity

Facility (ISPF)–based tool designed to

simplify the creation of migration ses-

sions. It provides an easy way to create

multiple sessions with minimum effort.

Benefiting from greater storage vendor

independence

Unlike most storage migration solu-

tions from competitors, the Softek

TDMF z/OS offering is designed to

be transparent to end users, and it

supports virtually any mainframe-

compatible storage, regardless

of server or storage manufacturer.

Automating data migration with functionality

on demand

The Softek TDMF z/OS solution offers

the following features:

Offline Volume Access (OVA)—Enables

selected programs to access the offline

point-in-time copy while the original

source volume continues to be used.

Point in Time (PIT) and Perpetual Point

in Time (PPIT)—Enables point-in-time

copies to be created and resynchro-

nized on a regular basis without having

to do a full copy, whether on a one-time

or a recurring basis. This enables users

to create regular volume synchronization

points that can be used for recovery.

Transmission Control Protocol/Internet

Protocol (TCP/IP)—Provides a means

of migrating volumes over distances

through any suitable communications

link supporting TCP/IP.

The Session Assistant feature simplifies the creation of migration sessions and lets you more easily create multiple sessions.

Softek TDMF z/OS platform features, functions and benefits

Feature Function Benefit

Storage vendor independence Host-based software migrates data across

leading storage environments

Supports flexibility in vendor choice when

conducting a technology refresh

Flexible migration options Provides control over I/O rate and CPU

overhead for read/write, pacing/throttling,

tunable copy and replication rate, and

adjustable block size of each read/write

Enables online migration activity while

maintaining optimal application performance

and service levels

Resilient architecture Current state of migration is maintained,

regardless of graceful or nongraceful

shutdown, to help ensure continued

recoverable migrations

Migration process can continue in the event

of server shutdown and restart

Global migration via TCP/IP Enables network migration Optimizes flexibility and allows for remote

data migration

Dynamic Swap Automatically directs I/O to a new location

after data replication completes

Allows data migration without disruption

Dynamic pacing/throttling Migration rates change automatically Helps minimize effect on application

performance

Auto operations interface Completely automates migration sessions,

with virtually no human intervention required

Increases productivity by automating

redundant activities

Fast copy Copies only allocated and modified tracks/

cylinders on the source volume to the target

volume

Speeds migrations and decreases costs

Full-Speed Copy Allows use of two I/O buffers for volume

migration, with overlapping read and write

operations

Faster performance for times when speed

counts the most

Active-In-Copy Moves large amounts of data without setting

up multiple small groups; limits the number

of volumes in the copy phase without

consideration to the size of the group

Minimizes the effect on the storage

subsystem when migrating large databases

or applications

Session Assistant Simplifies the creation of migration sessions Lets you create multiple sessions more easily

Robust interfaces Fully functional command line or ISPF screens

for configuration, monitoring and operation

Easier configuration, monitoring and operation

Note: The Softek TDMF z/OS offering supports the IBM OS/�90® Version �.10 operating system and all levels of the IBM z/OS operating system in the Job Entry Subsystem � (JES�) and Job Entry Subsystem � (JES�) environments. It also supports the z/OS operating system running as a guest to the IBM z/VM® platform. Softek TDMF offerings are also available for UNIX®, Linux® and Microsoft® Windows® platforms.

Moving data with the Softek TDMF family
