HP 3PAR InForm OS 3.1.1 MU1 Release Notes

System, HP 3PAR T-Class Storage System, and HP 3PAR F-Class Storage System – all in 64-bit
mode.
• Chunklet size on HP P10000 3PAR Storage Systems has been increased to 1GB. Chunklets
are the first layer of mapping in the InForm OS advanced internal virtualization that increases
storage management efficiency, capacity utilization, and performance. Chunklets virtualize
physical drives of any size into a pool of granular, uniform-sized virtual disks. The increase
in Chunklet size to 1GB on HP P10000 3PAR Storage Systems delivers headroom for support
of the rapid increase expected in capacity levels on enterprise SATA drives over the lifecycle
of storage system. Chunklet size for HP 3PAR T and F-Class Storage Systems remains unchanged
at 256MBs.
• T10 DIF Support on HP P10000 3PAR Storage System augments existing end-to-end internal
checks for data consistency.
• HP 3PAR Remote Copy Software now supports end-to-end CRC checksum for assured data
consistency.
• Node-by-node online software upgrades with “pause” (of online upgrade process after each
controller upgrade) are now supported for any online software upgrade post InForm OS 3.1.1,
including between major or minor versions of InForm OS. Previously, this approach to online
software upgrades was supported with InForm OS Maintenance Update (MU) releases only.
“Pause” of the online software upgrade process after each controller is upgraded enables
validation of active I/O on all host paths before the software is upgraded on the next controller.
• Metadata errors are now isolated to individual storage volumes, thereby shielding other
storage volumes from propagation of the metadata errors. The storage volumes with the
detected metadata errors are taken offline and repaired while the system remains online and
continues to serve data for other applications/tenants from other storage volumes.
• A new serviceability safety measure – controller node pre-integration test – is now available
to verify that a controller node is installed properly and ready to accept I/O load before it is
logically added to the cluster of controller nodes in the system.
• A new safety measure – Remote Copy link pre-integration test - is now available to the users
of HP 3PAR Remote Copy Software to verify the stability of remote copy links in advance of
adding these links within HP 3PAR Storage System for use with Remote Copy.
Autonomic Management for Agility and Ease of Use
HP 3PAR Peer Motion Software
HP 3PAR Peer Motion Software is the first non-disruptive, do-it-yourself data migration tool for
enterprise Storage Area Networks. Peer Motion delivers simple, fool-proof, non-disruptive data
mobility between HP 3PAR Storage Systems. With Peer Motion, HP 3PAR Storage System customers
can load balance I/O workloads across systems at will, perform technology refresh seamlessly,
cost-optimize asset lifecycle management, and lower technology refresh capital expenditure.
Unlike traditional block migration approaches, Peer Motion enables customers to migrate storage
volumes between any HP 3PAR Storage Systems online, non-disruptively, and without complex
planning or dependency on extra tools. Peer Motion leverages HP 3PAR Thin Built In™ technology
and HP 3PAR Thin Conversion Software to power the simple and rapid inline conversion of
inefficient, “fat” volumes on source arrays to more efficient, higher-utilization “thin” volumes on
the destination HP 3PAR Storage System. Peer Motion Manager orchestrates all stages of the data
migration lifecycle to ensure data migration is simple and fool-proof. Peer Motion software can be
ordered separately.
Autonomic System Rebalance
HP 3PAR Dynamic Optimization Software now delivers autonomic system rebalancing to drive
large scale performance optimizations with one button after adding new resources to the HP 3PAR
