Next steps

Install or enable MPIO on the host servers.

NOTE: After the Storage Center configuration is complete, run the host access wizard to configure host server access

and apply MPIO best practices. For the latest best practices, see the Dell Storage Center Best Practices document on

the Dell TechCenter site (http://en.community.dell.com/techcenter/storage/).

Two Servers Connected to Dual 12 Gb 4-Port SAS Storage Controllers

A storage system with four 12 Gb front-end SAS ports on each storage controller can connect up to two host servers, if each host

server has two SAS HBAs with dual SAS ports.

About this task

This configuration includes four fault domains spread across both storage controllers. The storage controllers are connected to each

host server using four SAS connections.

If a storage controller becomes unavailable, all of the standby paths on the other storage controller become active.

Steps

1. Connect fault domain 1 (shown in orange) to host server 1.

a. Connect a SAS cable from storage controller 1: port 1 to the first SAS HBA on host server 1.
