Know Your DataKnow 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?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?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 DrawbacksSAN 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 ConvergenceNAS 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?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 - DAS - DirectDirect Attached StorageAttached 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

LAN

Storage ConsolidationStorage 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 StorageNAS – Network Attached Storage

NAS provides a simple effective way to share files in a Local Area NetworkNAS devices are file server appliancesAppliance => simple to install, configure and manageUse industry standard network filing protocols over TCP/IP, i.e. connect to existing LANNAS has achieved broad market penetration, from low end through to high end to SANs

SAN - Storage Area NetworkSAN - Storage Area Network

Storage is networked behind file serversAllows consolidation and better utilization of storage through virtualizationBetter support for high availability configurations for business continuance and disaster recoverNon-disruptive expansion and maintenanceSAN ROI estimates* range from 65-297 percentToday SANs use Fibre Channel; expensive, and have only penetrated high end

*Source: CSFB, June 2001

IP SANsIP 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

Other Important ConsiderationsOther Important Considerations

• Ease of management

• Snapshot

• Mirroring

• Remote replication (disaster recovery)

Drivers of Networked StorageDrivers 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

Reference InformationReference 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 Reference Information Capacity GrowthGrowth

Reference Information will surpass all other information types by the end of 2004

Things to Pay Attention toThings to Pay Attention to

Know your business– What applications support NAS and which

data makes sense to live on a NAS deviceNAS “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…
