This chapter describes how to configure a VMware-based
host using the express configuration method.
Deciding whether to use this Express method
The express method for installing your storage array and accessing ThinkSystem System Manager is appropriate for setting up a standalone VMware host to a DE Series storage system. It is designed to get the storage system up and running as quickly as possible with minimal decision points.
Understand the workflow
This workflow guides you through the express method for configuring your storage array and ThinkSystem System Manager to make storage available to a host.
Configure management port IP addresses using DHCP
Configure the management port for communication between the management station and array controllers. In this express method for configuring communications between the management station and the storage array, you use Dynamic Host Configuration Protocol (DHCP) to provide IP addresses. Each controller has two storage management ports, and each management port will be assigned an IP address.
Configure the multipath software
Multipath software provides a redundant path to the storage array in case one of the physical paths is disrupted. The multipath software presents the operating system with a single virtual device that represents the active physical paths to the storage. The multipath software also manages the failover process that updates the virtual device. For VMware, you use the inbox Native Multipathing Plug-in (NMP).
Perform FC-specific tasks
For the Fibre Channel protocol, you configure the switches and determine the host port identifiers.
Perform iSCSI-specific tasks
For the iSCSI protocol, you configure the switches and configure networking on the array side and the host side. Then you verify the IP network connections.
Perform SAS-specific tasks
For the SAS protocol, you determine host port addresses and make the settings recommended in the Interoperability Matrix document.
Discover storage on the host
After assigning volumes to the host, you perform a rescan so that the host detects and configures the volumes for multipathing.
Configure storage on the host
You can use the storage assigned to an ESXi host as either a Virtual Machine File System (VMFS) datastore or a raw device mapping (RDM).
