enclosures. It contains the following sections:

■

“Host System Requirements” on page 43

■

“Configuration Considerations” on page 44

■

“Connecting Direct Attach Configurations” on page 46

■

“Connecting Switch Attach Configurations” on page 49

■

“Connecting Remote Management Hosts” on page 53

■

“Next Steps” on page 53

For additional recommendations on connecting controller enclosures to data hosts,
refer to the

Best Practices Guide

Host System Requirements

Data hosts connected to R/Evolution 2730 FC Controller Enclosures must meet the
following requirements:

■

To configure an FC HBA that is directly attached to controller enclosure host
ports, set the HBA parameters as specified in your storage system’s

Release

Notes

. This ensures the HBA can identify the system.

■

Data host operating systems must support multipathing. For information on
installing the R/Evolution MPIO DSM, refer to

Installing the R/Evolution 2730

MPIO DSM on Microsoft Windows Server 2003

available at the following

location:

■

To prevent Microsoft

Windows

data hosts from displaying the Found New

Hardware Wizard when the storage system is discovered, install the R/Evolution
SCSI Enclosure Services driver. For more information, see “Installing the
R/Evolution SES Driver for Microsoft Windows Hosts” on page 44.
