Connecting hosts

Host system requirements

Data hosts connected to 2312i G2 and 2324i 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
• 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:

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.

iSCSI host ports

2312i Modular Smart Array and 2324i Modular Smart Array use Internet SCSI (Small Computer System
Interface) interface protocol for host port connection, featuring either one or two controller modules. Each
controller provides two iSCSI host ports — supporting data rates up to 1Gb/second, featuring a 1.8 GHz
processor with128 MB memory, and 1 GB cache — using either one-way or mutual CHAP
(Challenge-Handshake Authentication Protocol).
(search the site for "multipath I/O overview")
MSA2000 Family SCSI Enclosure Services driver is required for Microsoft Windows 2003.
