14 Overview of the HP XP24000/XP20000 Disk Array
Description
Realizes the virtualization of the storage system.
Users can connect other storage systems to the
XP24000/XP20000 disk array and access the
data on the external storage system over virtual
devices on the XP24000/XP20000 disk array.
Functions such as TrueCopy and Cache Resid-
ency can be performed on the external data.
Provides storage logical partition and cache
logical partition: Storage logical partition al-
lows you to divide the available storage among
various users to reduce conflicts over usage.
Cache logical partition allows you to divide
the cache into multiple virtual cache memories
to reduce I/O contention.
Enables users to configure the Fibre Channel
ports and devices (LUs) for operational environ-
ments (for example, arbitrated-loop and fabric
topologies, host failover support). The security
function allows users to restrict host access to
data on the disk arrays. Mainframe users can
restrict host access to LVIs based on node IDs
and logical partition (LPAR) numbers.
Provides support for SNMP monitoring and
management. Enables SNMP-based reporting
on status and alerts. SNMP agent on the SVP
gathers usage and error information and
transfers the information to the SNMP manager
on the host.
Provides detailed records of all operations
performed using Remote Web Console (and
the SVP).
Allows open-system users to concatenate mul-
tiple LUs into single LUs to enable open-system
hosts to access the data on the entire storage
system using fewer logical units.
Enables users to convert single volumes (LVIs
or LUs) into multiple smaller volumes to improve
data access performance.
Allows users to lock and unlock data into cache
in real time to optimize access to your most
frequently-accessed data.
Enables the mainframe host to issue multiple
I/O requests in parallel to single LDEVs in the
storage system. Compatible PAV provides
compatibility with the IBM Workload Manager
(WLM) host software function and supports
both static and dynamic PAV functionality.
