4 Connecting hosts Host system requirements Data hosts connected to P2000 G3 MSA System FC LFF/P2000 G3 MSA System FC SFF arrays must meet the following requirements: • Depending on your system configuration, data host operating systems may require that multi-pathing is supported. TIP: See the HP StorageWorks P2000 G3 and MSA2000 Family VDS and VSS Hardware Providers Installation Guide and HP StorageWorks P2000 G3 and MSA2000 Family MPIO DSM Installation Guide to aid in planning and implementing your MPIO DSM installation. If fault tolerance is required, then multi-pathing software may be required. Host-based multi-path software should be used in any configuration where two logical paths between the host and any 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. • Use Windows Server MPIO DSM with Windows Server 2003. To obtain the 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. • Use native Microsoft MPIO DSM support with Windows Server 2008. Use either the Server Manager or the command line interface (mpclaim CLI tool) to perform the installation. Refer to the following web sites for information about using the Windows 2008 native MPIO DSM: http://support.microsoft.com/gp/assistsupport http://technet.microsoft.com (search the site for "multipath I/O overview") • Use the HP Multi-path Device Mapper for Linux Software with Linux servers. To download the appropriate device mapper multi-path enablement kit for your specific enterprise Linux operating system, go to http://www.hp.com/go/devicemapper. • To prevent Microsoft Windows 2003 data hosts from displaying the Found New Hardware Wizard when the storage system is discovered, install the SCSI Enclosure Services driver. Download your product's SCSI Enclosure Services (SES) driver package from http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Related Products. NOTE: P2000 Family SCSI Enclosure Services driver is required for Microsoft Windows 2003. Connecting the enclosure to data hosts A host identifies an external port to which the storage system is attached. Cable connections vary depending on configuration. Common cable configurations are shown in this section. A list of supported configurations resides on the P2000 G3 product site at http://hp.com/support/manuals. Locate the following documents: • HP StorageWorks P2000 G3 MSA System Installation Instructions • HP StorageWorks P2000 G3 MSA System Cable Configuration Guide These documents provide installation details and describe newly-supported direct connect, switch-connect, and expansion configuration options for P2000 G3 MSA System products. Any number or combination of LUNs can be shared among a maximum of 64 host ports, provided the total does not exceed 512 LUNs per P2000 G3. FC host ports HP P2000 G3 MSA System FC controllers use Fibre Channel interface protocol for host port connection, featuring either one or two controller modules. Each controller module provides two host ports configured HP StorageWorks P2000 G3 MSA System FC User Guide 41
