Chapter 1. Introduction - IBM TotalStorage NAS 300 User Reference

Chapter 1. Introduction

The NAS Gateway 300 connects clients and servers on an IP network to Fibre
Channel storage, efficiently bridging the gap between LAN storage needs and SAN
storage capacities.
This appliance offers a storage solution for both Windows, UNIX
environments, including mixed Windows-UNIX environments that enable Windows
and UNIX clients and servers to share the same Fibre Channel storage.
Model G27 replaces Models G01 and G26. Enhancements provided by the new
model include:
v More options in configuring Ethernet connections
v More options in configuring Fibre Channel connections
v More options for tape backup
v Faster processor
v Gigabit Ethernet connection
v Faster adapters
The dual-node Model G27 features:
v Two engines (IBM 5187 NAS Model 7RY), each with:
v Optional adapters:
In addition, the Model G27 provides clustering and failover protection. This
high-availability design helps protect against appliance failure to provide continuous
access to data.
