Connecting Hosts
This chapter describes how to connect data and management hosts to controller
enclosures. It contains the following sections:
■ “Host System Requirements” on page 39
■ “Connecting the Enclosure to Data Hosts” on page 40
■ “Connecting Remote Management Hosts” on page 40
Host System Requirements
Data hosts connected to MSA2000 Family 2012sa Modular Smart Arrays must meet
the following requirements:
■ To configure an HBA that is directly attached to controller enclosure host ports,
set the HBA parameters as specified in the MSA QuickSpecs. QuickSpecs can be
found from your HP MSA products page at
http://www.hp.com/go/msa.
Select MSA SAN Arrays, and then select your product. The link for QuickSpecs
will be on the right.
■ Depending on your system configuration, data host operating systems may
require that multipathing is supported.
If fault tolerance is required, then multipathing software may be required. Host-
based multipath software should be used in any configuration where two logical
paths between the host and nay storage volume may exist at the same time. This
would include most configurations where there are multiple connections to the
host or multiple connections between a switch and the storage.
To obtain the MSA2000 Family MPIO DSM, go to the HP MSA products page at
http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product,
and go to Related products.
■ To prevent Microsoft

Windows
®
data hosts from displaying the Found New
Hardware Wizard when the storage system is discovered, install the MSA2000
Family SCSI Enclosure Services driver. For more information, see “Installing the
MSA2000 Family SES Driver for Microsoft Windows Hosts” on page 40.
