Preface

Data migration service (DMS) is a block-level, online and offline feature
introduced in the iSR6200 Intelligent Storage Router (iSR6200) data transport
device. The SANsurfer iSCSI/FC Router Manager utility provides this licensed
feature to simplify data migration jobs for almost zero downtime, while providing
protection against common user errors.

Intended Audience

This guide is intended for end users responsible for administration of data
migration services using the iSR6200 Intelligent Storage Router. It is assumed
that the user has a basic knowledge of managing SANs and SAN storage.

What’s in This Guide

This preface provides a general overview of DMS and the SANsurfer iSCSI/FC
Router Manager utility, and covers the intended audience, related materials,
document conventions, and contact information for technical support.

The remainder of this guide is organized into the following chapters and
appendices:

 Chapter 1 Introduction lists the DMS and SANsurfer iSCSI/FC Router

Manager features.

 Chapter 2 Getting Started describes the direct attached, fabric, and

multipath configurations, lists the supported fabric and array types, and
describes hardware and software setup.

 Chapter 3 Data Migration Objects describes the primary items that compose

DMS.

 Chapter 4 Data Migration Licenses describes the two types of migration

licenses and provides instructions for license key installation.

 Chapter 5 Performing Data Migration provides information on the data

migration service licensed features that you can view and configure using

example.

 Chapter 7 Performance and Best Practices describes the factors affecting

DMS performance and offers suggestions for obtaining maximum
performance, provides recommendations for high availability and redundant
configurations, guidelines for choosing DMS options, and a few general
precautions for DMS usage.

 Chapter 8 Restrictions details the restrictions that apply to the DMS when

reconfiguring logical unit numbers (LUNs) on a storage array and removing
an array after completing data migration jobs.

 Appendix A Configuring the Data Path Through iSR6200 for Online Data

Migration provides the information you need to configure several types of

1 Introduction

The iSR6200-based data migration service (DMS) is block-based data migration
that is independent of a SAN, server, storage protocol (Fibre Channel and iSCSI),
and storage vendor. Application downtime during data migration is always critical.
DMS supports both online (local and remote) and offline data migration across
Fibre Channel and iSCSI storage arrays. Even offline data migration using DMS is
designed to minimize application downtime by allowing the user to configure all
migration related tasks while the application remains online, and to migrate the
data at a very high speed while the application is offline. DMS is designed such
that any person with knowledge of SAN or SAN storage administration can use
this service.

Important data migration features include the following:

 Fibre Channel SAN vendor independent: The iSR6200 supports

Brocade
also supports data migration across multi-vendor Fibre Channel fabrics.

 Heterogeneous array support: The iSR6200 supports data migration

across heterogeneous arrays (arrays manufactured by different vendors).
For a list of the storage array types for which DMS currently provides
support, see “Supported Storage Arrays” on page 2-11.

 Multi-protocol support: The iSR6200 supports data migration across

multiple storage networking protocols, including Fibre Channel, iSCSI, and
Fibre Channel over Ethernet (FCoE). The iSR6200 allows data migration
between storage arrays of the same or different protocols.

 Migration to thin-provisioned storage: The iSR6200 supports migration to

“thin-provisioned” storage. During the data migration process, the iSR6200
can migrate from regular-provisioned storage to thin-provisioned storage.
When used with space reclamation tools, this type of storage delivers
significant cost savings in deploying new enterprise storage. For details, see

“Migration to a Thin-Provisioned LUN” on page 3-9.

1–Introduction

 Online remote migration: The iSR6200 supports online data migration

between two remote data centers. Currently, a reasonable bandwidth (fat
pipe) between two data centers is required to handle the initial copy of the
data and the change rate during the data copy. The data migration rate
depends on the round-trip latencies between two locations and the available
dedicated bandwidth. Each iSR6200 supports up to 512 concurrent remote
migration jobs.

 Data scrubbing: The iSR6200 supports data scrubbing. When retiring the

old storage or redeploying the storage, data scrubbing provides security by
overwriting the existing data with another data pattern, so that the secured
data cannot be retrieved.

 Ease of use: Manage the iSR6200 using the intuitive graphical user

interface (GUI) that provides many wizard-based operations, and the
command line interface (CLI). Both provide user-level protection and ease of
use. Any SAN administrator or storage administrator can perform safe and
quick data migration.

 Data security and sanity: The iSR6200 provides features to classify a

storage array as “source only.” This classification ensures that you cannot
configure LUNs out of this array as destination LUNs, and thus minimizes
the chances of data corruption. It also provides a Verify Migration Job wizard
to compare data on the source LUN with that on the destination LUN to
indicate that the data copy occurred without any data loss or corruption.

 Migration job scheduling: Data migration may be disruptive to

business-critical applications; therefore, minimizing application downtime is
very important. DMS provides several job scheduling options, including the
Configure Only option, which allows you to complete the time-consuming
task of configuring data migration jobs without requiring any downtime. The
different I/O size capabilities for migration jobs enables you to tune the
storage array’s performance during sequential read/write operations.

 Load Balancing: The Load Balancing option provides a way to deal with

older-generation, lower-speed arrays (such as 2Gb and 4Gb Fibre Channel)
being migrated to higher speed (4Gb and 8Gb Fibre Channel) arrays using
higher-speed (4Gb and 8Gb) Fibre Channel switches.

 Data migration service logs: DMS logs are maintained separately from the

system logs. DMS logs are designed to help the service professional
maintain a full, detailed history of each job performed, and can be submitted
as a part of the migration report to the customer.

1–Introduction

 Logging and troubleshooting: System logs are designed to store a

significant number of details that can be used for debugging and
troubleshooting. The save capture command (see “save capture” on

page 6-50) helps to capture the configuration details, system logs, and

iSR6200 state at any time, and can be used for troubleshooting if the need
arises.

 Licensing: DMS licenses provide capacity-based (per TB) and array-based

licenses. For more information, see 4 Data Migration Licenses.

This chapter helps you get started using data migration service with the iSR6200
and SANsurfer iSCSI/FC Router Manager by providing information in the following
sections:

 Supported Configurations
 “Hardware and Software Setup” on page 2-12

Supported Configurations

This section describes and illustrates the supported topologies (direct attach,
fabric, and multipath), and lists the supported fabric and array types.

Supported Topologies

Supported topologies include direct attach configuration, fabric configuration, and
multipath configuration as described in this section.

Direct Attach Configuration

Figure 2-1 shows a direct attach configuration with a single-blade or dual-blade

iSR6200.

Fabric Configuration

Figure 2-2 shows a typical setup for data migration with a dual-fabric, high

availability (HA) configuration with both array controller ports and one port from
each iSR6200 blade connected to each fabric. This configuration enables the
iSR6200 to perform load balancing.

Figure 2-2. Single- and Dual-Blade High Availability Setup

Table 2-2 shows the migration rates that can be achieved for a single blade,

depending on the bandwidth capability of the storage array.
