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?
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)
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)
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
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
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

DAS - Direct Attached Storage
LAN
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
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
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 => 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
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 65297 percent
Today SANs use Fibre Channel;
expensive, and have only
penetrated high end
*Source:
CSFB, June 2001
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
Servers
GB Ethernet Switches
Native TCP/IP with Industry
Standard iSCSI
encapsulation Gig E.
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 RFI’s more quickly, reduces cost and delivers
revenues to the bottom line
Reference Information Capacity
Growth
Reference Information will surpass all other information types by the end of 2004

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…
