Introduction
This application note describes fibre channel switch based Storage Area Network (SAN)
configurations for RA8000/ESA12000 storage systems on Windows NT Intel platforms. For mixed
platform heterogeneous SAN configurations refer to the "Heterogeneous Storage Area Networks"
application note, and the applicable platform specific application notes listed in Table 3.
Enterprise Network Storage Architecture (ENSA)
The Compaq Enterprise Network Storage Architecture is key to supporting Compaq's NonStop
eBusiness strategy; through ENSA, Compaq leverages industry standards to allow deployment of
storage where applications need it. ENSA uses the Compaq StorageWorks product family to deliver
the storage solutions that address non-stop computing requirements like availability, reliability,
performance, scalability, manageability, and data backup/restore capabilities. ENSA addresses the
storage issues that our customers expect to face now and in the future. Compaq SANs address today's
issues including:
Data protection
High availability
Increased distance
High connectivity
High bandwidth
Multi-vendor platform support
Enterprise backup support
Economical capacity growth
Scalability
Investment protection
With the addition of multi-switch fibre channel Fabric support in the RA8000/ESA12000 FC storage
products and the integration of Enterprise Backup Solutions into the SAN, Compaq has taken the next
evolutionary step in delivery of the ENSA vision. Our customers can now realize the full benefits of a
scalable Storage Area Network providing the robust backbone needed to address dispersed server
operation with shared storage access and backup across the enterprise.

Page 2: Product Overview
For the highest availability, two hardware paths between the cluster servers and the RA8000 or ESA12000 FC storage system can be configured using Compaq’s Secure Path for Windows NT. This configuration provides two separate physical paths between the servers and the storage. - Page 3 SAN Enterprise Backup Management Legato NetWorker and SmartMedia software manages and automates the backup-and-restore process using Compaq servers, disk arrays, tape libraries and FC interconnect hardware. SAN Access Management Switch Fabric Zoning – The FC switch Zoning feature provides a means to control SAN access at the node port level.

Additionally, SSP allows the setting of host modes and LUN offsets for each HBA connected to the array. The host mode is specially tailored to the storage communication techniques of the operating system.

- Page 13 This SAN configuration utilizes the high availability features of controller Multiple- Bus failover and Compaq Secure Path for Windows NT software. With 2 FC HBAs in each server, and 2 FC switches, a second separate path to the storage is provided to each server. The 2 switches form isolated Fabrics providing the highest level of storage path fault tolerance should a failure occur with any path component - FC HBA, FC Switch, Fabric path interconnect, or storage controller.

Assumes 1 FC HBA per server, an even storage port count, and no EBS ports. 16-port FC Switches, total number of switch ports available for Servers and Storage is 52 Maximum Server Connectivity, Up to 40 Servers and 3 Storage Systems (12 storage ports/6 Active, 6 Standby)
- Page 25 Application Note storage system. (See Windows NT Server/Storage Rules). This situation can be avoided by using FC switch Zoning to create separate Zones for each of the server groups that you wish to configure with specific storage systems. Performance considerations, assuming relatively equal server load: If using four storage systems, for balanced performance across all servers configure one quarter of the servers on each of the storage systems and equally on the controller port pairs.
