The IBM TotalStorage® SAN32M-2

Express Model is designed specifically to meet the needs of medium-size and enterprise SAN environments. It can be used to create a wide range of highperformance SAN solutions, from simple single-switch configurations to larger multi-switch configurations which support fabric connectivity and advanced business continuity capabilities. Infrastructure simplification solutions for IBM

_`® xSeries® servers include storage consolidation and high-availability server clustering with IBM TotalStorage disk storage arrays. Business continuity solutions include data protection with

IBM TotalStorage tape libraries and devices and IBM Tivoli® Storage

Manager data protection software.

A single SAN32M-2 Express Model can serve as the cornerstone of a Storage

Area Network for those who want to obtain the benefits of storage

consolidation and are just beginning to implement Fibre Channel storage systems. Such an entry-level configuration can consist of one or two Fibre Channel links to a disk storage array or to an LTO™ tape drive. An entry-level sixteen-port storage consolidation solution can support up to fifteen servers with a single path to either disk or tape.

The FlexPort feature is designed to enable a base switch to grow to thirtytwo ports, in eight port increments, to support more servers and more storage devices without taking the switch offline.

A high-availability solution can be created with redundant switches. This capability is ideal for server clustering environments. Such a configuration can support from fourteen to thirty servers, each with dual Fibre Channel adapters cross-connected to redundant

SAN32M-2 switches which are crossconnected to a dual-controller storage system.

While the SAN32M-2 Express Model can be the foundation of medium-sized

SANs, it can be configured to participate as a full member in a tier enterprise SAN with other members of the

IBM TotalStorage SAN m-type family.

This capability provides investment protection as SAN requirements evolve and grow over time.

Simple SAN configuration

The introduction of large capacity, highavailability storage systems offers new opportunities for cost reduction through storage consolidation and infrastructure and management simplification. In older environments each server accessed its own dedicated storage capacity using either internal disks that were contained within the server or disks which were part of an external system attached exclusively to that server. It has become difficult to sustain that approach as the requirement for both storage capacity and numbers of servers has increased.

Storage consolidation is a fundamental objective of infrastructure simplification and is based on the philosophy that it is easier to share and manage capacity contained in a large capacity, highperformance and high-availability external storage system such as provided by the IBM TotalStorage DS4000 and

DS6000 series. Fibre Channel Storage

Area Networks (SANs) were developed to provide efficient, high performance access from many servers to many storage devices.

While it is possible, in small environments, to direct-connect servers to external storage systems using fibre channel links, it is more common to configure a SAN switch between the servers and the storage system to enable multiple servers to share the same storage capacity. This simple

SAN is depicted in the following diagram.

The SAN32M-2 Express Model was designed specifically for use as the

SAN switch in this type of configuration.

It is easy to install and easy to manage.

The tan, green and blue servers represent heterogeneous server types which are members of the same SAN and share capacity of the large disk system.

The SAN32M-2 Express Model can be upgraded to 32 ports and is futureready to support 4 Gbps servers and storage devices as they are introduced.

Its flexible design allows participation with other SAN m-type switches in fabrics that evolve as requirements change. And it supports advanced functions to enable participation in complex fabrics including cascaded switches and ISL trunks.

redundant Host Bus Adapters. And each Host Bus Adapter is connected to a different SAN switch, and each switch is connected to a different controller in a disk system. Every effort is made to provide continuous application access to data.

High availability SAN configuration

Many applications require continuous operation. A common design approach to achieve that objective is to run multiple instances of the application across a cluster of servers. When a server fails or must be taken offline for maintenance a backup server is available to continue operation with a minimum of impact. Redundant paths to data are usually configured in a clustered server environment for the same reasons in an effort to provide continuous access to data. Each server is configured with

The SAN32M-2 Express Model is an excellent switch to use in a clustered server environment. Separate SAN switches enable two separate SAN fabrics, which are desirable as a means to minimize or eliminate single points of failure. The tan cluster shown above provides redundant components at every level and is designed to minimize application outages.

Business continuity solution

Many small and medium size companies want to implement a business continuity or remote backup capability to meet strict new regulatory requirements. The SAN32M-2 Express Model can provide the SAN connectivity required for these environments. The diagram on the following page is intended to represent two different sites. The blue side represents the production site and the green side represents the remote or backup site.

Many disk subsystems, including

IBM TotalStorage DS4000 series, are capable of copying data to a remote location. The data path for the remote copy operation is represented by the red links in the diagram.

Two SAN32M-2 Express Model switches can be connected over metro distances (up to 10km) using longwave

SFP optical transceivers. Longer distances can be supported with SAN routers which transmit Fibre Channel

Protocol (FCP) over Internet Protocol

(IP) networks.

SAN32M-2 Express Model switches can also be used to connect two locations to enable remote data backup. An

Information Lifecycle Management (ILM) application such as IBM Tivoli Storage

Manager (TSM) which runs on a server in the production site can write data to a tape system at a remote location. The same distance capabilities are available as for the business continuity solution described above.

First time SAN user characteristics

Easy to install and maintain

The SAN32M-2 Express Model includes capabilities designed to make it easy to install and easy to maintain for system administrators who have minimal experience with SAN components. EFCM

Basic provides intuitive graphic switch management capabilities. Installation and backup/restore wizards are included for novice users which are designed to help guide them through switch setup and operation.

EFMC Basic (formerly SANpilot) is designed for first-time SAN users with minimum SAN expertise. EFCM Basic can help simplify monitoring and configuration management. Functions include

Web browser access, fabric and switch configuration management, port activity monitoring and reset, firmware updating, event logging, diagnostics and online help. Whether you have a single

switch or a small fabric to manage,

EFCM Basic capabilities and functionality can help simplify management of your SAN solution.

Pay-as-you-grow scalability

The FlexPort Expansion feature is designed to support scalable switch upgrades. The FlexPort feature provides an activation key and eight shortwave

SFPs which upgrades the switch in eight-port increments while helping avoid fabric disruption. The ability to increase switch capacity while maintaining service helps customers implement a pay-as-you-grow strategy while minimizing impact to applications.

High performance

The SAN32M-2 Express Model provides 4 Gbps performance on all ports.

Each port auto-negotiates to 4, 2 Gbps or 1 Gbps, full duplex depending on the capabilities of the attached device or switch. Up to 256 Gbps aggregate throughput is possible with 32-port configurations.

Network performance can be enhanced with Open Trunking feature which automatically balances performance throughout a network while minimizing storage administrators’ involvement.

Open Trunking is designed to optimize the total throughput between two switches automatically by redirecting traffic from high-utilization links to links with available bandwidth. Open

Trunking is designed to continuously monitor loads on all links, detect congestion and automatically balance traffic across available ISLs without operator interaction. Based on constant traffic monitoring, Open Trunking acts to help improve throughput and reroute traffic efficiently.

The SAN32M-2 Express Model is designed to provide hot-swappable, load-sharing dual power supplies designed to allow the switch to remain online if one power supply fails. Dual power cords allow attachment to separate power sources to help improve availability. Hot-swappable power supplies with integrated cooling components help eliminate downtime for service when replacing a failed component and help reduce or eliminate the risk of erroneously cabling a replacement switch because of a simple component failure. Failed power supplies require IBM service or switch replacement and hot-pluggable optical transceivers can be replaced without taking the switch offline.

High-availability

Medium-size and enterprise businesses require high-availability switch fabric solutions. The SAN32M-2 Express

Model uses advanced applicationspecific integrated circuits (ASICs) to help minimize the number of internal components and thus improve reliability.

FlexPort technology is designed to support switch port upgrades without fabric disruption. In addition, HotCAT online code activation is designed to allow firmware to be downloaded and activated while the fabric switch remains operational. Redundant switches can be deployed for highavailability clustering applications.

Advanced solution management

Open System Management Server

(OSMS), a standard feature, is an ANSI

(American National Standards Institute)based capability that supports SAN management software from vendors such as VERITAS™, Tivoli and BMC.

OSMS is designed to extend the switch’s capability to include in-band management with an open systems host-based application. OSMS allows the fabric switch and devices attached to it to be “discovered,” or seen in a fabric through a framework software application.

SANtegrity™ Enhanced (Security

Suite) feature is designed to help enhance business continuity by reducing the impact of human influences on networked data. The feature includes

SANtegrity Binding and SANtegrity

Authentication.

Standards-based SANtegrity

Authentication is designed to force each device in the SAN to prove who they are in order to avoid unauthorized access and unauthenticated devices.

Preferred Path, a standard feature, is designed to allow a customer to define routes across a fabric. The Preferred

Path modifies the behavior of Open

Trunking by providing guidance for the balancing function. The Preferred Path configuration helps address user preference regarding exit port assignment but is subject to the standard rules regarding the Fabric Shortest Path First

(FSPF) protocol.

SANtegrity Zoning, a standard capability of Enterprise Operating System

(E/OS), provides hardware-enforced world wide name (WWN) and port zoning. SANtegrity Secure Management

Zone (SMZ) is designed to secure management access to local and remote

SAN devices over a secure connection.

SANtegrity Binding is designed to create multiple layers of access control, including port, switch and fabric binding.

Full Volatility feature is designed to support high-security environments, which require no customer data be retained after power-off. Full Volatility is designed to configure a switch or director so that no frame data is stored after a power-off.

High port density, rack space savings

Rapidly growing Fibre Channel SAN infrastructures place a premium on rack space. The SAN32M-2 Express Model uses SFP LC optical connectors and advanced packaging that requires only one-rack–unit (1U) height for 32 ports.

The SAN32M-2 Express Model is also tabletop stackable.
