HP 3PAR Virtual Lock Software

HP 3PAR Virtual Lock software is an optional feature that enforces the retention period of any
volume or copy of a volume. You must purchase the HP 3PAR Virtual Lock license to use this feature.
Locking a volume prevents the volume from being deleted intentionally or unintentionally before
the retention period elapses. You can use HP 3PAR Virtual Lock to specify the retention period for
each volume or copy of a volume.

HP 3PAR Adaptive Optimization Software

HP 3PAR Adaptive Optimization Software analyzes sub-volume, region-level disk access rates for
a given array over a scheduled period of time and then performs a data migration of regions
between tiers according to a cost versus performance preference. Disk usage is optimized by
having frequently accessed data moved to the higher performance tier (for example, RAID 1 using
Solid State Disks, or SSDs) while infrequently accessed data is moved to the lower cost tier (for
example, RAID 6 on Nearline disks).
Active use of AO requires an Adaptive Optimization license. Contact your local HP representative
for information.
AO uses System Reporter statistics gathered from logical disks and physical disks to relocate
customer data on physical volumes in an optimal way. AO relocation accomplishes two primary
goals:
Increases performance of frequently accessed regions of data by moving those regions to
higher-tier storage (for example, moving to solid state drives from normal spinning media).
Improves cost-efficiency by moving lightly accessed regions of data to a lower performance
and less expensive tier of storage (for example, moving from regular drives to nearline drives).
Because storage tiers can be of different RAID types, capacity efficiency is maximized by using
only RAID1 for the most frequently accessed storage and by using RAID5 or RAID6 for less frequently
accessed storage. Other benefits include:
AO can migrate data from a fully occupied tier of storage to another tier that has more
available capacity.
AO can also be regularly scheduled so that it can adjust the data layout as your data usage
changes over time.
AO is built on top of the new version of System Reporter (SR), which also now runs as part of the
HP 3PAR OS. SR must have been actively gathering data on VV regions for a period of time.
Analysis of the data collected by SR is performed to identify regions within virtual volumes that are
either heavily used or lightly used, and then generates a series of secondary tasks to move these
regions to faster or slower storage tiers.
Running AO on the HP 3PAR OS itself offers these advantages:
AO configurations can now be created, modified, and removed using the CLI or the HP 3PAR
Management Console.
Beginning with HP 3PAR 3.1.2, the external HP System Reporter is no longer necessary to
use Adaptive Optimization
The database scheme has been restructured on node to be more efficient and reliable.
The actual movement of data can use data from a given time period in the past rather than
only from the immediate past. This means data movement can occur at low-utilization time
periods while using an analysis of statistics gathered during peak periods.
A time limit can be set for data movement so that scheduled data is moved only during
low-utilization periods rather than during peak periods.
