Chapter 1: Introduction

Overview

Storage networks have grown out of the need to move data between consolidated

storage devices and storage clients or application servers. The best approach to

connecting storage to clients is to configure the remote devices as virtual storage,

which allows you to format, store, and access this data the same as you would a

local disk. However, the key to this new technology is not the storage devices or the

client-side software, but the high-speed storage networks that transfer data at

speeds comparable to local access times. This section provides a brief introduction

to storage networks, and shows how the GigaSAN Bridge fits into this architecture.

Traditional Storage Architecture

Traditionally, storage has been attached directly to each application server.

However, with the growth of data-intensive applications over the past decade, this

method of data storage has led to a variety of problems, ranging from overloaded

networks, insufficient time for overnight data backup, additional storage needed for

database replication on failover servers, and increased management overhead for

distributed storage devices. Companies have therefore been struggling to find ways

to deliver better performance for on-line data access services, guarantee one hundred

percent uptime for critical applications, and provide backup or replication for databases

that are growing at an exponential rate – all while keeping costs under control.

Creation of NAS and SAN

Network Attached Storage (NAS) and Storage Area Networks (SAN) have been

designed to solve some of the problems caused by the explosive growth in storage.

Both NAS and SAN networks allow you to consolidate storage on a common server.

NAS then provides file sharing for clients on Windows or Unix workstations using

protocols such as the Network File System (NFS). This approach allows users to

access shared data resources via standard interfaces provided by their operating

system, such as simply mapping to a network drive.

SANs, on the other hand, provide a more comprehensive solution for consolidating

data storage. SANs allow you to create a common pool of data storage in a central

location, which can then be allocated to application servers or end users by making

it appear as a locally attached storage device (i.e., virtual storage). SANs allow you

to consolidate storage at a central location for easier management, allocate any

amount of storage as a virtual device to users running different operating systems,

expand virtual storage on the fly without having to shut down an application server,

and allow users to easily configure storage to suit their specific environment or

application requirements. SANs also provide facilities for copy, mirror, replication,

and failover operations.

SAN resources may also be linked together in a distributed network by positioning

storage devices closest to points of heavy access. By duplicating key data across

the company, you can shift the loading from a single server and supporting network

to permit faster access to all users, creating failover support at the same time.

Introduction

1-2

Storage Networks

In the traditional storage architecture, corporate networks were already overloaded

handling requests for data-intensive applications and daily database backups. But,

once you introduce virtual storage into the network, even more data has to be

shuffled across the network, passing from the storage server to the application

server, and then from the application server to the end user. The only way to relieve

network congestion is to create a separate storage network. Up to now, this has

been built on Fibre Channel.

Fibre Channel

Fibre Channel (FC) is optimized for large data file transfers. It provides a data rate of

1 to 4 Gbps, and a packet size that is more suitable for moving large blocks of

sequential data. Compared to SCSI, FC allows you to attach a larger number of

storage devices to a host – up to 127 devices can attached to an arbitrated loop.

However, the overhead of installing a storage network with completely new intercon-

nection devices and fiber cabling, along with the expertise required to manage this

unique type of network has prevented most companies from making the plunge.

However, where economies of scale make it feasible, Fibre Channel is still an

excellent choice for building large storage farms. The GigaSAN Bridge is therefore

designed to link either SCSI or FC storage to your network. And for companies that

have already installed an FC SAN, the GigaSAN Bridge can be used to link existing

FC resources to new storage farms or remote sites over Gigabit Ethernet.

Gigabit Ethernet

With the advent of Gigabit Ethernet, it is now possible to build a storage network

based on an existing and well-known networking technology. Commonly available

Ethernet networking devices, adapters and cabling can be used to build a storage

network – all without the need for any new management skills. Moreover, network

protocols such as iSCSI allow you use less expensive Gigabit Ethernet to build an

infrastructure for connecting SCSI or FC storage to application servers and storage

clients.

Built-in Storage Server

Storage networks have traditionally required a dedicated storage server positioned

between your storage devices and clients. However, the GigaSAN Bridge includes

a built-in storage server, further reducing the overhead for storage networks. With

the GigaSAN Bridge, you can attach up to 30 SCSI storage devices or 127 FC

storage devices directly to the storage bridge, and then allocate storage to any NAS

or SAN client on your storage network.

Client-side Storage Network Adapter

To fully isolate the storage network from your corporate network and optimize

performance on the client side, each storage client should have one adapter

connected to the corporate network and another connected to the storage network.

Adapters designed specifically for storage access over Gigabit Ethernet have only

recently become available on the market. For example, the SANNIC (an iSCSI

Description of Hardware

1-3

storage network adapter) includes an on-board CPU and PCI-to-PCI bridge that

offloads all data transfers from the host machine’s CPU. It can easily support

storage clients or application servers, with an interface that fits either 32- or 64-bit

PCI connectors. Operating at 33/66 MHz, this card can increase bus throughput up

to 4.2 Gbps. Moreover, it provides more efficient throughput for large sequential data

transfers by supporting Jumbo frames up to 8 KB. Compared to standard Ethernet

frames that run only up to 1.5 KB, using Jumbo frames significantly reduces the

per-packet overhead required to process protocol encapsulation fields.

Storage Client

The GigaSAN package includes software that allows storage clients to scan the

network for storage servers, attach virtual storage, and configure advanced options.

This software must be installed in each storage client on your storage network.

Description of Hardware

Gigabit Ethernet Ports

The GigaSAN Bridge provides dual Gigabit ports for attaching the bridge to the

storage network with a trunked connection. Both speed and failover protection are

critical elements for any storage network. These dual ports allow you to increase

bandwidth up to 4 Gbps for a full-duplex connection, while at the same time

providing failover in case one of the links (or ports) should fail.

This device includes two 1000BASE-T (RJ-45) ports that operate over 4-pair CAT-5

or CAT-5e cable. These ports provide auto-negotiation for speed (1000/100/10 Mbps),

duplex mode (full/half), flow control (on/off) and wiring (MDI/MDI-X).

Auto-negotiation is used to automatically select the optimum data rate and

transmission mode. (If a device connected to one of these ports does not support

auto-negotiation, you can manually configure the communication mode.) These

ports support auto-negotiation of flow control to prevent port buffers from

overflowing. Auto-MDI/X is also provided to allow the GigaSAN Bridge to be

connected to any network device with ordinary straight-through cable, regardless of

whether it is a host computer, a switch, or a router. (See Appendix B for a description

of the pinouts on straight-through cable.)

Both Gigabit ports should be attached to the same device. Therefore, you need to

configure a dual-port path (i.e., aggregate link or trunk) throughout the storage

network for each intermediate network device and client that has to access the

GigaSAN Bridge. Also note that when connecting to a storage client or application

server, you need to install two storage network cards and configure them as a trunk.

SCSI Ports

The GigaSAN Bridge includes two SCSI-160 sockets on the rear panel. Each socket

provides an interface to a wide SCSI bus for up to 15 storage devices, including disk,

tape, optical, or cartridge changers. The GigaSAN Bridge automatically scans for

new storage devices each time it boots up, and auto-negotiates the width for wide or

narrow devices, and the speed for 160/80/40/20 Mbps (i.e., Ultra Wide, Ultra, Fast

and Standard SCSI).

FC Ports

The GigaSAN Bridge includes a slot on the rear panel for an optional FC adapter.

Using an arbitrated loop, you can connect up to 127 storage devices to an FC port.

The GigaSAN Bridge automatically scans for new FC devices each time it boots up,

and automatically detects the speed, frame size, and device ID.

Approved cards currently include specific cards in the QLogic 2200 Series (1GB)

and QLogic 2300 Series (2GB). The adapters supported for the GigaSAN Bridge

include single port cards for copper (with HSSDC connector) or multimode fiber

optic media (with SFF LC connector).

Status Indicators

LEDs – Status LEDs are located on the front panel for the Gigabit Ethernet ports,

key system indications, and the SCSI/FC storage buses. These indicators are

shown below and described in the following table.

Ethernet Management Port

An Ethernet management port is also provided for configuring the GigaSAN Bridge’s

storage server functions. This RJ-45 port operates at 10 or 100 Mbps, and can be

connected to your corporate network (instead of your storage network) for easy

management access from any host computer. This port is designed to provide

management access to all the configuration options in the GigaSAN Bridge using a

standard Web browser, Telnet, or SNMP software.

Service Port

The GigaSAN Bridge contains a console port on the rear panel that provides limited

access to key configuration commands and system status information. This is an

RS-232 serial port with a DB-9 connector. A PC may be connected to this port for

system diagnostics and monitoring via a null modem cable. (See Appendix B for

serial port wiring options.) Refer to the Console Management Guide for detailed

information about the command options provided by the console interface.

Load-sharing Power Supplies

The GigaSAN Bridge uses slide-in modules for two load-sharing power supplies.

Load sharing reduces the load carried by an individual module and subsequently

extends the lifetime of both modules. By using two modules, the full power load can

be smoothly assumed by a single module in case the other module fails.

Features and Benefits

The GigaSAN Bridge includes the standard features associated with a network

device. But since a storage server and management software are also built into this

device, it includes all the hardware and software required to build a complete

storage network. You just add storage network adapters (e.g., Accton’s SANNIC)

and cabling for each storage client or application server, install the client software on

each client, allocate storage on the server side, and then attach to virtual storage on

the client side. A detailed list of the features provided by the GigaSAN Bridge is

shown below:

• Provides an alternative to expensive Fibre Channel storage networks with more

reliable and widely known Gigabit Ethernet – allowing you to use common network

hardware and protocols for both your corporate network and storage network

• Allows you to create a separate storage network for higher reliability and improved

performance – providing a bandwidth of up to 4 Gbps

• Provides failover protection using trunked network ports

• Includes a storage server embedded in the bridge

• Provides client-to-storage connectivity by passing native SCSI commands and

data either over modified UDP (SAN/IP) or over standard IP (iSCSI)

• Provides both NAS and SAN access to the same storage pool

• Centralizes storage for improved security and easier management, lowering your

overall cost for hardware and maintenance

• Consolidates storage for shared access by multiple clients or application servers

• Provides storage access to clients using a wide range of operating systems

• Virtual storage appears and functions the same as locally attached devices

• Boundless virtualization allows you to allocate storage across device, cabinet,

vendor or interface boundaries

• Advanced management interface for storage configuration, expansion, replication,

mirror, snapshot, copy and backup operations

• Server-less backup delivers zero impact for application servers and the network

• Remote management of the GigaSAN Bridge and storage resources via Windows

application, Web browser, and SNMP applications
