What a SAN Does

SAN is a technology that addresses

two critical storage connectivityproblems

Host-to-storage connectivity

Storage-to-storage connectivity

SAN technology uses block-level I/Oprotocols

SAN Fabrics

One or more switches connected

together

Traffic is routed between them

Identified through

Domain ID

Worldwide Name (WWN)

5/67


Motivat ions for Netwo rked Storage

The efficiency from isolating physical

connectivity from logical connectivity

Topology limitations eliminated

The ease of logically connecting a

single array port to multiple host

ports, and vice-versa

Fan-out (one storage port services

multiple host ports)

Fan-in (one host port accesses

storage ports on multiple arrays)

Dynamic vs. static configuration Distance limits can be alleviated

Provides better scalability

Basic Structu re of a SAN

SAN: a networked architecture that

provides I/O connectivity betweenhost computers and storage devices

Fibre Channel network

Typically, a physical network of Fibre

Channel connectivity devices:

interconnected FC Switches and

Directors

For transport, an FC SAN uses FCP

IP network

Uses standard LAN infrastructure:

interconnected Ethernet switches, hubs

For transport, an IP SAN uses iSCSI

Communication over a SAN is at the

block I/O level

HBA or NIC HBA or NIC HBA or NIC HBA or NIC

FC or IPNetworks


8/67


Fibre Channel Overview

Fibre Channel is a serial data transfer interface intendedfor connecting high-speed storage devices to computers

The high speed is obtained through the following

processes:

Networking and I/O protocols (such as SCSI commands) aremapped to Fibre Channel constructs

These constructs are encapsulated and transported within Fibre

Channel frames

With this, the high-speed transfer of multiple protocols over the samephysical interface is possible

Fibre Channel Addressing

Required to route the frames from source to destination

24-bit addresses (3 bytes) are assigned when a Fibre Channel node

is connected to the switch

the fabric login AL_PA is generally 00 unless the device is in an Arbitrated Loop

FCIP Overv iew

Fibre Channel over IP (FCIP) is an IP-based storage networking

technology

FCIP combines the advantages of Fibre Channel and TCP/IP

FCIP enables the transmission of information by tunneling data

between SAN facilities over IP networks

Facilitates data sharing over a geographically distributed area

FCIP is designed to be transparent to Fibre Channel

In most cases, EMC customers utilize FCIP technology in one of two

ways: To allow replication operations to be conducted across an IP network

To connect Fibre Channel SAN islands to extend the reach of the fabric

FCIP Entit ies

From the IP network perspective, FCIP entities are peers

and communicate using TCP/IP

From the FC fabric perspective, nodes are unaware of

the existence of link

Path taken by FC frame follows normal routing procedure

of IP network

FCIP entities must be configured with IP address and

TCP port of FCIP entities with which it will initiatecommunication



FCIP Rou ting

FCIP enables multiple local Fibre Channel SANs to be

interconnected, or remote SANs to be managed, over an

IP network backbone

Zoning

A separate zone for each HBA

Makes zone management easier

when replacing HBAs

Types of zones:

WWN based zoning (soft zoning)Access is controlled using WWN

WWNs defined as part of a zonesee each other regardless of theswitch port they are plugged into

HBA replacement requires the zone

to be modified EMC recommended

Port zoning (hard zoning)

Port-to-port traffic

Ports can be members of more thanone zone

Each HBA only sees the ports inthe same zone

If a cable is moved to a different port,zone has to be modified

Hybrid zones (mixed zoning)

Contain ports and WWNs

Simplified management

Service for multiple platforms

Application performance

SAN provides a dedicated network

Database-management

system/transaction processing

Fast scalability

Hundreds of server and storage devices

Overcomes distance limitations

options

Storage consolidation optimizes total cost

Business Benefits

Consolidate storage and servers toreduce costs

Fewer resources to manage

Reduce energy consumption

Business continuity

Consolidation reduces risks via

multiple backup devices withmultiple points of control

Business flexibility

More information moves faster

Meet your existing service levelagreements

Manageability Centralize storage management and

automate control of devices

Fewer people manage more


62/67


Benef its o f Larger Directors

Larger directors = lower price per port, fewer stranded ports

In modular systems, price per port decreases as system port densityincreases

Significant pricing advantage above 256 ports

Fewer ports stranded at core and edge

High-density directors reduce data center operational costs

Small footprint reduces facility expense

Fewer systems mean simplified management

Greater flexibility to support ongoing growth

Scalable SAN provides savings beyond the network

Large storage and server pools drive high storage/server utilization, butrequire large fabrics that are typically limited by maximum qualified domainsper fabric

Network-hosted volume management promotes higher storage utilization,greatly simplified management, and nondisruptive data migration
