4 Connecting hosts Host system requirements Data hosts connected to 2312sa G2 and 2324sa G2 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 MSA2000 Family VDS and VSS Hardware Providers Installation Guide and HP StorageWorks 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 2000sa G2 Modular Smart Array MPIO DSM with Windows Server 2003. To obtain the 2000sa G2 Modular Smart Array 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 2000sa G2 Modular Smart Array SCSI Enclosure Services driver. Download 2000sa G2 Modular Smart Array 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: MSA2000 Family SCSI Enclosure Services driver is required for Microsoft Windows 2003. Connecting the enclosure to data hosts Cable connections vary depending on configuration. Common cable configurations are shown in this section. A complete list of supported configurations resides on the MSA2000 G2 product site at http://hp.com/support/manuals. Locate the HP StorageWorks MSA2000 G2 Cable Configuration Guide, which is updated to describe newly-supported direct connect, switch-connect, and expansion configuration options for the MSA2000 G2. Any number or combination of LUNs can be shared among connected servers, provided the total does not exceed 512 LUNs per MSA2000 G2. Moreover, a volume cannot be mapped to LUN zero. SAS host ports 2312sa Modular Smart Array and 2324sa Modular Smart Array use Serial-attached SCSI (Small Computer System Interface) interface protocol for host port connection, featuring either one or two controller modules. Each controller provides four SAS host ports supporting data rates up to 3Gb/second per lane - and four lanes per connector - featuring a 1.8 GHz processor with128 MB memory, and 1 GB cache.
