HP XP7 Owner Guide (H6F56-96006)

• Command tag queuing
• Industry-standard failover and logical volume management software
• SNMP remote disk array management
The XP7’s global cache enables any fibre-channel port to have access to any logical unit in the
disk array. In the XP7, each logical unit can be assigned to multiple fibre-channel ports to provide
I/O path failover and/or load balancing (with the appropriate middleware support) without
sacrificing cache coherency.
The user should plan for path failover (alternate pathing) to ensure the highest data availability.
The logical units can be mapped for access from multiple ports and/or multiple target IDs. The
number of connected hosts is limited only by the number of FC ports installed and the requirement
for alternate pathing within each host. If possible, the primary path and alternate paths should be
attached to different channel cards.
Open systems host platform support
XP7 Storage supports most major open-system operating systems, such as Microsoft Windows,
Oracle Solaris, IBM AIX, Linux, HP-UX, and VMware. For more complete information on the
supported operating systems, go to: http://www.hp.com. Each supported platform has a user
guide that is included in the XP7 documentation set. See the HP XP7 Documentation Roadmap for
a complete list of XP7 user guides, including the host configuration guides.
Open systems configuration
After physical installation of XP7 Storage has been completed, the user configures the disk array
for open-systems operations with assistance as needed from the HP representative.
Please see the following documents for information and instructions on configuring XP7 Storage
for open-systems operations:
• The host configuration guides provide information and instructions on configuring XP7 Storage
and disk devices for attachment to the open-systems hosts.
NOTE: Queue depth and other parameters may need to be adjusted for the disk array. See
the appropriate configuration guide for queue depth and other requirements.
• The HP XP7 Remote Web Console User Guide provides instructions for installing, configuring,
and using Remote Web Console to perform resource and data management operations on
XP7 Storage.
• The HP XP7 Provisioning for Open Systems User Guide describes and provides instructions
for configuring the XP7 for host operations, including FC port configuration, LUN mapping,
host groups, host modes and host mode options, and LUN Security.
Each fibre-channel port on XP7 Storage provides addressing capabilities for up to 2,048
LUNs across as many as 255 host groups, each with its own LUN 0, host mode, and host
mode options. Multiple host groups are supported using LUN Security.
• The HP XP7 SNMP Agent User Guide describes the SNMP API interface for XP7 Storage and
provides instructions for configuring and performing SNMP operations.
• The HP XP7 Provisioning for Open Systems User Guide and HP XP7 Volume Shredder for
Open and Mainframe Systems User Guide provide instructions for configuring multiple custom
volumes (logical units) under single LDEVs on XP7 Storage. The HP XP7 Provisioning for Open
Systems User Guide also provides instructions for configuring size-expanded logical units by
concatenating multiple logical units to form individual large logical units.
