2. Recommended maximum number.
The drives must be added four at a time to create RAID groups, unless they are spare drives.
Software features and functions
XP7 Storage provides advanced software features and functions that increase data accessibility
and deliver enterprise wide coverage of online data copy/relocation, data access/protection, and
storage resource management. HP software products and solutions provide a full set of industry
leading copy, availability, resource management, and exchange software to support business
continuity, database backup and restore, application testing, and data mining. The following tables
describe the software that is available on XP7 Storage.
Table 3 Virtualization features and functions
DescriptionFeature
Provides logical partitioning of the cache which allows you to divide the cache
into multiple virtual cache memories to reduce I/O contention.
Cache Partition
Supports the virtualization of external disk arrays. Users can connect other disk
arrays to XP7 Storage and access the data on the external disk array via virtual
Cache Residency
devices created on XP7 Storage. Functions such as Continuous Access Synchronous
and Cache Residency can be performed on external data through the virtual
devices.
Table 4 Performance management features and functions
DescriptionFeature
Cache Residency locks and unlocks data into the cache to optimize access to the most
frequently used data. It makes data from specific logical units resident in a cache, making
Cache Residency
all data accesses become cache hits. When the function is applied to a logic unit,
frequently accessed, throughput increases because all reads become cache hits.
Performs detailed monitoring of the disk array and volume activity. This is a short term
function and does not provide historical data.
Performance Monitor
Enables the mainframe host to issue multiple I/O requests in parallel to the same
LDEV/UCB/device address in the XP7. Parallel Access Volumes provides compatibility
Parallel Access Volumes
with the IBM Workload Manager (WLM) host software function and supports both static
and dynamic PAV functionality.
Table 5 Provisioning features and functions for Open systems
DescriptionFeature
Provides automated movement of sub LUN data for a multi tiered Thin Provisioning pool.
The most accessed pages within the pool is dynamically relocated onto a faster tier in
Smart Tiers
the pool. This improves performance of the most frequently accessed pages while giving
the remaining data sufficient response times on a lower cost storage.
The LUN Manager feature configures the fibre channel ports and devices (logical units)
for operational environments.
LUN Manager
The LUN Expansion feature expands the size of a logical unit (volume) to which an open
system host computer accesses by combining multiple logical units (volumes) internally.
