Poll 1 Placeholder

Does your company plan to purchase NAS or SAN equipment this year?

– Yes – No

NAS and SAN Henry Baltazar

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 65 297 percent Today SANs use Fibre Channel; expensive, and have only penetrated high end

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)

Do you think that NAS may someday replace tape as the backup medium of choice?

Yes No

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

Networked Storage Grows

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…

Typical Deployment Scenario: Workgroup Storage

 Expand storage capacity for both server and clients  Keeps storage accessible and available while minimizing costs  Supports collaborative, heterogeneous workgroups  Extends life of general purpose servers

Macintosh Client Windows-based General Purpose Server Windows Client T-1 Link Ethernet UNIX Client Remote Site 1

Typical Deployment Scenario: Email storage

 Off-load e-mail archives or attachments to a NAS device   Improves server backup Extends life of e-mail server    Minimizes client mailbox restrictions Optimizes e-mail server performance Enables easier compliance with new retention regulations

E-mail Server E-mail Client E-mail Attachments Ethernet

Typical Deployment Scenario: Storage Consolidation

 Expand storage capacity for both server and clients  Eliminates “islands” of data    Single logical view of data that can be expanded as required Simplifies storage management and maintenance costs Extends life of general purpose servers
