Agenda• Old Environment - Infrastructure

• Old Environment – Challenges• Existing Environment• Advantages of Existing Environment• Put the Puzzle Together• The Future of our Backups• Backup Best Practices

Old Environment - Challenges• Daily admin tasks required an abundance of time

• No central management point

• Restores required multiple tape handlings, inventory operations, and take on average 25 minutes

Old Environment – Challenges

• Client backups were missed due to limitations of the drive speeds which caused exceeding backup windows

• Tapes proved unreliable for full system restore.

• Retention period was decreased from 1 month to 2 weeks due to increased data growth

Agenda• Old Environment - Infrastructure• Old Environment – Challenges

• Existing Environment• Advantages of Existing Environment• Put the Puzzle Together• The Future of our Backups• Backup Best Practices

Existing Environment

• Backup Infrastructure– Veritas Netbackup Datacenter version 5.0– 1 Master 4 Media Servers– 2 Disk based backup units “VTL”– 1 Tape Library can hold up to 1000 tapes– 2 LTO-2 fiber attached tape drives are capable of

245 GB per hour– Network Attached Storage (NAS) backup using

NDMP– Netbackup Shared Storage Option (SSO)

• Backup Policy Changes– Backup schedule: weekly full backups and daily

incrementals. – Retention period: all data are retained for 2

weeks on disk and 3 months of full backups on tape

– Full backups are averaging 2.5 Tb within an 8 hour backup window

– Backup speeds are limited to the speed of the disk controller on the drive array.

VTL Defined

• Virtual Tape Library

• Can virtually create multiple libraries and tape drives that write data to disk in format that the backup software believes is tape.

NDMP Defined

• Network Data Management Protocol

• Open protocol used to control data backup of a NAS device via fiber channel verses IP

SSO Defined

• Shared Storage Option

• Allows a single tape drive to be assigned to multiple media servers.

• Allows multiple backup servers to write to shared libraries and tape drives without conflict.

• Advantages of Existing Environment• Put the Puzzle Together• The Future of our Backups• Backup Best Practices

Advantages of Existing Environment

• Central point to manage.

• Daily admin tasks take minutes – just long enough to verify that all completed successfully.

– No more rotating tapes, except off site.

• Disk based restores take less than 2 minutes.

– Takes longer to initiate the restore job than the actual operation takes to complete.

Advantages of Existing Environment

• All backup schedules are completed in windows specified.

• Confidence and success rate in restores has dramatically increased.

• Put the Puzzle Together• The Future of our Backups• Backup Best Practices

Put the Puzzle Together

• Getting vendors to work together– EMC Celerra – NAS Device

– VERITAS (Symantec) Netbackup

– Overland REO (Disk) and NEO (Library)

Agenda• Old Environment - Infrastructure• Old Environment – Challenges• Existing Environment• Advantages of Existing Environment• Put the Puzzle Together

• The Future of our Backups• Backup Best Practices

The Future of our Backups• Move from a 5 server infrastructure to 3 due to

higher processing capabilities of servers.

• Upgrade network connections for Netbackup servers to Gigabit!

• Expansion chassis for disk library due to increased data.

Agenda• Old Environment - Infrastructure• Old Environment – Challenges• Existing Environment• Advantages of Existing Environment• Put the Puzzle Together• The Future of our Backups

• Backup Best Practices

Backup Best Practices• Backup client settings should be standardized for

network settings, an example would be to hard set to 100/Full.

• Still need tape!

• Don’t use virtual stand alone tape drives for NDMP with Netbackup.

Backup Best Practice• Set up of NDMP attributes through Netbackup is case

sensitive.

• Must have license key for NDMP option of Netbackup.

• Disk based backup units should be configured as RAID 3 for increased data write performance.

– RAID-3 dramatically increase the write performance on the disks verses RAID-5

Virtualization Overview

• What is Virtualization

• Typical Consolidation Project Goals

• Process Improvements

• Consolidation Approach

• Benefits Realized from Virtualization

Agenda

• What is Virtualization• Key Challenges

Agenda

What is Virtualization?

• A Technology that allows a single machine to run multiple operating systems at once.

Virtualized MemoryEach application sees its own logical memory,

independent of the physical memory

Virtualized NetworksEach application sees its own logical network,

independent of the physical network

Virtualized ServersEach operating system instance sees its

own logical server, independent of the physical servers

Virtualized StorageEach application sees its own logical volume,

independent of the physical disks

Defining Virtualization

Virtualization:Technology that enables logical representations of

physical resources

• Key Challenges• Typical Consolidation Project Goals

Agenda

• Current Model of 1 Application per 1 Server has resulted in an

overabundance of servers and with limited power and rack space

• Simplifying and Consolidating the IT Infrastructure

• Optimizing Server Performance and Loading

– According to Gartner 85% of x-86 servers are only utilizing 15% or less of its computing resources

– Average server builds takes about 6 to 8 hours

• Minimizing Maintenance Tasks and Reallocating Resources to Strategic Business Initiatives

– On Average, of the time an IT employee works on servers, 72% of the time is performing server maintenance & Support Tasks (BIOS, Firmware updates, etc…); 28% Assigned to Support Strategic Initiatives.

• Key Challenges

• Typical Consolidation Project Goals• Process Improvements

Agenda

Typical Consolidation Project Goals

• A more flexible and scalable architecture

• An architecture that is easier and less expensive to support

• High availability at lower cost

• Improved office space and server room utilization

Typical Consolidation Project Goals

• Reduced total cost of ownership

• Disaster recovery at an affordable cost

• Improve test & development environments

• Improve server maintenance processes

• Key Challenges

• Process Improvements• Consolidation Approach

Agenda

Process Improvements

• Improve asset management system / capacity planning process i.e.; buy computing resources when they are needed, not when application needs to run on a under utilized stand alone server

• Promote applications and code changes quickly and efficiently across the IT infrastructure

Process Improvements

• Implement standards:

– Virtualization

– Hardware

– Storage (SAN\iSCSI)

– Disaster recovery

• Implement lights-on org structure – maintenance can be done during the day

• Key Challenges

• Consolidation Approach• Benefits Realized from Virtualization

Agenda

Consolidation Approach

• Consolidate in tandem with “technology refresh” cycle and/or warranty expirations

• Executive buy-in for the consolidation project is key

• Gain buy in from Application Development team

• Map storage to NAS/SAN – “Virtual Networking”

Post - Virtual Environment

Consolidation Approach• What Chicago is trying to accomplish

– We have 24 XP workstations that require 24x7 uptime– 12 application servers requiring upgrades and/or additions

• 3 Print Servers

• 2 Monitoring Servers

• 2 NT Domain Controllers (Chicago still needs old Domain)

• 1 File Server

• 1 Sharepoint Server

• 2 Cava Servers (Used for NAS Virus Scanning)

• 1 Video conferencing server (PolyComm)

Consolidate 36 systems into 4

servers!

• Key Challenges

Provisioning Speed & Hardware Technology Refresh

• Previous procedure (before virtualization) = Approximately 6 to 8 hours to build one server

– Build and configure hardware– Load Operating System– Load and configure tools (Backup, Resource Kit, Monitoring, etc,,,)– Assign 2 IP addresses – Pull 3 network connections copper or fiber– Turn over to application team to load and configure software

• Consolidated procedure (after virtualization) = 30 minutes to build one virtual machine (server)

– Copy\clone standard virtual server file – OS and tools are pre-loaded and configured– Network connectivity only needed for ESX Server physical frame.– Assign 1 IP address to virtual machine instance– Turn over to application team to load and configure software
