Table 5 Provisioning features and functions for Open systems (continued)
DescriptionFeature
The Thin Provisioning feature virtualizes some or all of the system's physical storage. This
simplifies administration and addition of storage, eliminates application service
Thin Provisioning
interruptions, and reduces costs. It also improves the capacity and efficiency of disk
drives by assigning physical capacity on demand at the time of the write command
receipt without assigning the physical capacity to logical units.
Converts single volumes (logical volume images or logical units) into multiple smaller
volumes to improve data access performance.
Virtual LVI
Protects data in logical units / volumes / LDEVs from I/O operations illegally performed
by host systems. Users can assign an access attribute to each volume to restrict read
and/or write operations, preventing unauthorized access to data.
Data Retention
Table 6 Provisioning features and functions for Mainframe
DescriptionFeature
Converts single volumes (logical volume images or logical units) into multiple smaller
volumes to improve data access performance.
Virtual LVI
Restricts host access to data on the XP7. Open system users can restrict host access to
LUNs based on the host's world wide name (WWN). Mainframe users can restrict host
access to volumes based on node IDs and logical partition (LPAR) numbers.
Volume Security for
Mainframe
Protects data from I/O operations performed by hosts. Users can assign an access
attribute to each logical volume to restrict read and/or write operations, preventing
unauthorized access to data.
Volume Retention
Table 7 Data replication features and functions
DescriptionFeature
Performs remote copy operations between disk arrays at different locations.
Continuous Access Synchronous provides the synchronous copy mode for open
Continuous Access Synchronous
and
systems. Continuous Access Synchronous Z provides synchronous copy for mainframe
systems.
Continuous Access Synchronous
Z
Creates internal copies of volumes for purposes such as application testing and
offline backup. Can be used in conjunction with True Copy or Continuous Access
Journal to maintain multiple copies of data at primary and secondary sites.
Business Copy and
Business Copy Z
Snapshot creates a virtual, point- in- time copy of a data volume. Since only changed
data blocks are stored in the Snapshot storage pool, storage capacity is substantially
Snapshot (open systems only)
less than the source volume. This results in significant savings compared with full
cloning methods. With Snapshot, you create virtual copies of a data volume in the
Virtual Storage Platform
This feature provides a RAID storage based hardware solution for disaster recovery
which enables fast and accurate system recovery, particularly for large amounts of
Continuous Access Journal and
Continuous Access Journal Z
data which span multiple volumes. Using Continuous Access Journal, you can
configure and manage highly reliable data replication systems using journal volumes
to reduce chances of suspension of copy operations.
This feature provides compatibility with IBM Extended Remote Copy (XRC)
asynchronous remote copy operations for data backup and recovery in the event
of a disaster.

Table 8 Security features and functions
DescriptionFeature
This feature implements encryption for both open systems and mainframe data
using the encrypting disk adapter. It includes enhanced key support up to 32
