  equipment this year?
• Yes
• No

Know Your Data

• This is the only real implementation rule
• What type of data? Files? Application Data? Big
  or little files?
• How often is data accessed, and by how many
  users?
• How much are you willing to spend to store it?

9
Why Use NAS?

• Relatively inexpensive to deploy since there is
  no need for special hardware (i.e. Fibre Channel
  switches, HBAs)
• Easy to deploy If you can set up a file server,
  you can easily set up NAS
• Readily communicates with multiple platforms
  (CIFS, NFS, AppleTalk, Novell)

10
What About SANs?

• Best option for high performance since it already
  has 2 Gbps with 4 Gbps and 10 Gbps Fibre Channel
  on the way.
• Block level access to storage is preferable for
  some applications like databases
• Used for carving up Enterprise RAID systems (EMC,
  IBM, HDS)

11
SAN Drawbacks

• Interoperability is not quite plug-n-play
• Not easy to learn or implement
• Not geared towards data sharing. Servers must be
  connected to SAN to share
• Management is still evolving

12
NAS and SAN Convergence

• NAS head units Attach to Fibre Channel SANs
  allowing clients to store files on SAN resources.
• Network Appliance FAS 900 series is a storage
  system which allows connections via NAS, Fibre
  Channel SANs and iSCSI.
• EMC Celerra, HP StorageWorks NAS 8000

13
What Else To Look For?

• Increased Data Protection Mirroring and
  snapshots are becoming more common on NAS
  platforms
• Emergence of ATA drive based NAS Creates low
  cost, high capacity market segment which is
  attractive for nearline storage market
• Improved clustering improves NAS performance and
  reliability

• Performance
• Price
• Support policy
• Upgrade path

Navigating Today's Enterprise Storage Requirements

DAS - Direct Attached Storage

• Storage architecture used for the past 30 years
• Storage devices are directly attached to servers
• The last decade saw massive growth in demand for
  storage
• Business continuance and disaster recovery led to
  requirements DAS could not satisfy
• This has led to emergence of networked storage
  architectures

18
Storage Consolidation

• Consolidating storage can bring enormous
  benefits. You must carefully discuss and
  understand several issues
• Applications
• Platforms
• File types and their use
• Data value
• Regulatory/Compliance requirements
• Growth requirements - Scalability
• Availability needs - Redundancy
• Performance requirements
• Disaster Recovery
• Staff expertise and availability
• Budget

19
NAS Network Attached Storage

• NAS provides a simple effective way to share
  files in a Local Area Network
• NAS devices are file server appliances
• Appliance gt simple to install, configure and
  manage
• Use industry standard network filing protocols
  over TCP/IP, i.e. connect to existing LAN
• NAS has achieved broad market penetration, from
  low end through to high end to SANs

20
SAN - Storage Area Network

• Storage is networked behind file servers
• Allows consolidation and better utilization of
  storage through virtualization
• Better support for high availability
  configurations for business continuance and
  disaster recover
• Non-disruptive expansion and maintenance
• SAN ROI estimates range from 65-297 percent
• Today SANs use Fibre Channel expensive, and have
  only penetrated high end

21
IP SANs

• Cost and inter-operability problems of Fibre
  Channel have limited take up of SANs
• IP Storage protocols (iSCSI etc.) have been
  developed to allow SANs to be implemented over
  standard Gigabit and 10 Gigabit Ethernet Networks
• They leverage many existing Internet protocols,
  for security, discovery, zoning etc.
• This allows low cost IP-SANs to be deployed using
  standard networking infrastructure

GB Ethernet Switches
Native TCP/IP with Industry Standard iSCSI
encapsulation Gig E.
22
Other Important Considerations

• Ease of management
• Snapshot
• Mirroring
• Remote replication (disaster recovery)

Drivers of Networked Storage

• File based data is still growing at 50 year
  over year
• Data today has a whole new set of values
• Reference Information is driving new market opps.
• Regulatory and Compliance are driving on line
  data
• The premise of NAS is it is easy to manage
• IT needs this

Reference Information

• Unique Attributes
• Larger average file size
• One 4 sec QuickTime movie clip (3,300KB) consumes
  68 times more storage as a single jpeg image
  (1200x800 d.p.i.) (49KB)
• Increased retention periods
• Decades become indefinite Financial Services,
  Health Care, Government
• Information authenticity, integrity, and security
• High frequency of collaboration increased
  likelihood of concurrent file access
• Collaborative software development, CAD/CAM,
  Print / Publishing
• On line access unlocks incremental value
• Reducing access time to data empowers
  organizations to fulfill RFIs more quickly,
  reduces cost and delivers revenues to the bottom
  line

29
Reference Information Capacity Growth
Reference Information will surpass all other
information types by the end of 2004
75 CAGR
92 CAGR
61 CAGR

Things to Pay Attention to

• Know your business
• What applications support NAS and which data
  makes sense to live on a NAS device
• NAS creep these things multiply
• Figure out how to manage
• Value added software integration
• What is required for business success backup,
  replication, virus protection, etc
• NAS and Networked Storage is evolving
