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

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)

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

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
Physical address is switch specific and dynamically generated by
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

Fabric Secu ri ty : Zon ing
Zone
Controlled at the switch layer
List of nodes that are made aware
of each other
A port or a node can be a member
of multiple zones
Zone Set
A collection of zones
Also called zone config
EMC recommends Single HBA
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

Typical Cus tomer IT Issues and SAN Solut ions
Issue EMC SAN Solution
Costs of information management
rising
Consolidate storage and storage
management to lower total cost of ownership
Longer response time for applicationsBalance server, storage, and SAN workloads
for optimal performance
Decentralized storage is hard to
manage and hard to change
Increase storage usage and simplify
management by pooling storage
Need better processes for information
backup and disaster recovery
Centralized SAN-attached storage simplifies
data protection, backup, and information
recovery
Company mergers require data
migration and high-availability
improvements
SAN infrastructures provide the greatest
storage flexibility, widest interoperability, and
most sophisticated data-migration and -
availability options

Benef its o f SAN
Functional Benefits
High availability and manageability
All servers access same storage
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
Better backup, replication, and recovery
options
Storage consolidation optimizes total cost
of ownership
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

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
