configuration can consist of one or two Fibre Channel links to a disk storage array or to an LTO™ tape drive. An entry-level, 16-port storage consolida- tion solution can support up to

15 servers with a single path to either disk or tape. The FlexPort feature is designed to enable a base switch to grow to 16 ports, in eight port incre- ments, to support more servers and more storage devices without taking the switch offline.

A high-availability solution can be cre- ated with redundant switches. This capability is ideal for server clustering environments. Such a configuration can support from 14 to 30 servers, each with dual Fibre Channel adapters cross- connected to redundant SAN32M-2 switches which are cross-connected to a dual-controller storage system.

While the SAN32M-2 can be the foun- dation of medium-sized SANs, it can be configured to participate as a full mem- ber in a tier enterprise SAN with other members of the IBM TotalStorage SAN m-type family. This capability helps pro- vide investment protection as SAN requirements evolve and grow over time.

Simple SAN configuration

The introduction of large capacity, high- availability storage systems offers new opportunities for cost reduction through storage consolidation and infrastruc- ture, 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 both the requirement for storage capacity and the number of servers has increased. Storage consoli- dation is a fundamental objective of infrastructure simplification and is based on the philosophy that it is easiest to share and manage capacity contained in a large capacity, high-performance 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 environ- ments 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 was designed specifi- cally 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 heteroge- neous server types which are members of the same SAN and share capacity of the large disk system. The SAN32M-2 can be upgraded to 32 ports and is future-ready to support 4 Gbps servers and storage devices as they are intro- duced. Its flexible design allows partici- pation with other SAN m-type switches in fabrics that evolve as requirements change. And it supports advanced functions to help enable participation in complex fabrics including cascaded switches and ISL trunks.

High availability SAN configuration

Many applications require continuous operation. A common design approach to achieve that objective is to run multi- ple instances of the application across a cluster of servers. When a server fails or must be taken offline for mainte- nance, a backup server is available to help continue operation with a minimum of impact. Redundant paths to data are usually configured in a clustered server
