Limited Storage Scalability & Compatibility

Windows® File Server

UNIX® File Server

Windows® File Server

Primary Data Center Growth managed by

adding servers

Windows® File Server

Servers unevenly utilized

Difficult for UNIX® and Windows® users to securely share data

User migration disruptive

Labor-intensive management

5

Difficult, Slow Backup Process

Primary Data Center

Windows®

Server

Time: many hours

FullBackup

IncrementalBackup

Time: many hours

Tape backups required for each server

Tape management required for each server

Backup takes a long time

Duplicate tasks at remote offices

Remote Offices

6

Difficult Restore Process

Primary Data Center

Windows® File Server

Off-site Tape Storage

Time to recover: many hours

Load full backup

Load incremental backups

Identify backup tapes

Load full and incremental backups

Downtime for users who need to access the data

Locate backup media

Tapes may be at off-site tape storage location

7

Lack of Business Continuance

Primary Data Center

Offsite Tape Storage

Challenges:

Expensive Slow disaster

recovery Long user downtime Risk of unrecoverable

backup due to backup error or faulty media

Windows® File Server

High Management Complexity

Primary Data Center

Protect from viruses and other security threats

Many file servers to manage

Manage OS patches and updates for each server

Migration without VFM

Benefits:

Shortens migration time Simplifies migration effort Minimizes client

downtime Tremendous flexibility in

executing consolidation• Consolidate in stages

• Location transparency

Migrate data

Decommission old storage devices

Update scripts and applications

Migrate data

Inform users

Users to reboot

Field support calls forbroken links to data

Decommission old storage devices

Plan and communicate

Create groups and shares

Benefits: Effortless Consolidation

Policy-based management• Schedule

• Bandwidth

• Inclusions/exclusions

• Post-migration tasks

Multiple consolidation jobs simultaneously across locations

Automatic reconfigure client mappings

Migration with VFM

Deploy Global Namespace

Marketing Dept

Benefits: Multi-domain Consolidation

Engineering Dept Each group manages its

own file servers

MultiStore™ allows single filer to be partitioned into smaller filers

Engineering Marketing

They want to consolidate, but each group wants control of administration and maintenance

Benefits:

Flexible administration and management

14

Benefits: Non-disruptive Expansion

Benefits:

Easier to manage expansion

Minimized downtime

Reduced user confusion

Additional disks can be easily added with little or no impact on system performance

Upgrade performance with new filer head
