Direct-attached cluster configuration

About this section

This section describes how to configure the following platforms in a direct-attached cluster configuration:

The following table describes the number of ports and cable connections required for a direct-attached cluster configuration.

Gateway model	Gateway HBA ports used	Storage subsystem ports used	Number of total cable connections	LUNs supported
GF270c	2	2	4	42
GF825c	4	4	4	168
GF920c	4	4	4	336
GF940c	4	4	4	672
GF960c	4	4	4	672

The following diagram shows how your gateway connects to your storage subsystem.

The following port-to-port scheme supports the maximum number of LUNs on each port in a redundant configuration.

Port-to-port connectivity scheme
Gateway 1	Storage subsystem
1A	1A
2B	2A
Gateway 2	Storage subsystem
1A	1B
2B	2B
