HP 3PAR InForm OS 3.1.1 MU1 Release Notes

Additional Ease of Use Enhancements
Greater number of simultaneous Full Copy operations and promote operations enables use
of Full Copy more broadly and at greater scale.
SMI-S 1.4 and SNMP v3 support enables enhanced standards-based management of HP
3PAR Storage Systems.
InForm OS CLI client now supports the IPv6 standard.
Thin Technologies for Efficiency and Capacity Reduction
Fine-grained 16KB Space Reclaim
HP 3PAR Thin Persistence Software leverages the HP 3PAR Thin Built-In ASIC to reclaim unused
space associated with deleted data simply, quickly, and non-disruptively. Thin Persistence is now
enhanced with the equivalent of a defragmentation tool that intelligently consolidates used” 16KB
pages from sparse regions, yielding higher reclaim efficiency of 128MB regions for reuse by other
volumes in the same CPG. Now, enhanced Thin Persistence means thin volumes on HP 3PAR
Storage Systems can stay as lean and efficient as possible.
Remote Copy Bandwidth Optimization
HP 3PAR Remote Copy Software now leverages the HP 3PAR Thin Built-In ASIC to detect and
eliminate the remote replication of zero pages during initial synchronization and ongoing
synchronous replication. As a result, precious remote copy link bandwidth is utilized efficiently by
replicating non-zero written data only. This capability also enables near-instant initial synchronization
of new volumes that are added to a remote copy group.
Special capacity savings stem when remote copy bandwidth optimization is coupled with HP 3PAR
Thin Conversion and Thin Persistence Software. Fully provisioned, “fat source volumes can be
converted simply and rapidly to higher efficiency, “thin” target volumes during remote replication
while making efficient use of remote copy bandwidth. Capacity associated with zero pages on
the source volume is eliminated on the replication target volume. Thin Persistence keeps the thin
target volume as lean and efficient as possible.
Additional Remote Copy Enhancements
Remote Copy over Fibre Channel now supports replication over 8Gb/s Fibre Channel links
between HP P10000 3PAR Storage Systems.
Remote Copy over IP now supports up to 4 Remote Copy links in 1-to-1 configuration for
greater resiliency and bandwidth.
Granular remote copy statistics are available for each replicated storage volume, enabling
insight into the storage volumes that are top consumers of remote copy bandwidth.
Remote Copy ease of use is extended with enhanced capability to start all remote copy groups
on an HP 3PAR Storage System with a single command.
Remote Copy users now have the flexibility to replicate a Read/Write Virtual Copy of a
replicated storage volume to same or another destination HP 3PAR Storage System. Customers
with separate development or data mining data centers can leverage the enhanced capability
to provide these data centers with access to production data without interrupting the replication
process on the base storage volume.
Subnet restrictions removed
Prior to InForm OS 3.1.1, there were some restrictions related to using subnets 192.x.x.x, 172.x.x.x,
and 10.x.x.x such as not being able to use multiple instances of these subnets on the storage
system. As of InForm OS 3.1.1, these restrictions have been removed.
