levels even in the event of a cache or controller node failure. HPE 3PAR Persistent Cache leverages
the clustered HPE 3PAR Architecture with its unique Mesh-Active design to preserve write-caching
by rapidly re-mirroring cache to the other nodes in the cluster in the event of a failure. Persistent
Cache is supported on all quad-node and larger HPE 3PAR arrays, including StoreServ 7400 and the
InServ F400-making 3PAR HPE the only vendor to incorporate this industry-leading service level
protection capability into midrange as well as high-end arrays.
HPE 3PAR Persistent Ports
HPE 3PAR Persistent Ports is a Tier 1 resiliency feature that allows for non-disruptive online
software upgrades on HPE 3PAR StoreServ Storage systems without relying on multipathing
software. This feature, available on all HPE 3PAR StoreServ models, brings increased Tier 1
resiliency, across the StoreServ product line including the midrange platform by ensuring that host
paths remain online throughout the software upgrade process. The use of standard NPIV (N_Port ID
Virtualization) technology as defined by the Technical Committee T11 in the Fibre Channel -Link
Services (FC-LS) specification enables a single host-facing StoreServ port to assume the identity of
additional pre-designated partner ports, thus enabling transparent switchover of host path
connections. Persistent Port Technology is also designed to work with iSCSI and FcoE connectivity.
Starting from HPE 3PAR OS 3.1.3 Persistent Ports also autonomically fails over a front-end controller
node port that experiences physical connection loss from a cable pull or a failed switch; this unique
capability, for now is available for FC connectivity only.
HPE 3PAR Persistent Checksum
HPE 3PAR Persistent Checksum: Persistent Checksum is a data integrity feature built in to the HPE
3PAR OS that ensures data integrity to ensure end to end data protection via a T10 Data Integrity
Field (DIF). Persistent Checksum addresses media and transmission errors that can be caused by any
component in the I/O stack and provides additional protection above FC/Iscsi/ CRC transmissions.
With supported HBA’s on hosts T10- DIF tags are added and verified on the HPE 3PAR StoreServ
Storage system and when host HBA’s are not supported T10-DIF tags are added and verified on the
array target ports and backend HBA’s before dat is written to the array drives. This technology is
available on systems with GEN5 ASIC only.
HPE 3PAR Autonomic Rebalance
HPE 3PAR Autonomic Rebalance provides the ability to analyze how volumes on the HPE 3PAR
Storage System are using physical disk space and makes intelligent, autonomic adjustments to
ensure optimal volume distribution when new hardware is added to the system. The best practice is
to run the Autonomic Rebalance (Also known as tunesys) after new hardware is added to the system.
HPE 3PAR Web Services API
HPE 3PAR Web Services API delivers a programming interface for implementing durable automation
of storage management tasks with HPE 3PAR StoreServ Storage systems. Web Services API provides
a well-defined application programming interface that customers can use for incorporating the
storage infrastructure into their platform for end-to-end automation of their service delivery and
management. The Web Services API implementation is based on RESTful Web API service using
HTTPS, principles of REST, and data structures represented with JSON (JavaScript Object Notation).
HPE 3PAR OS Administration Tools
The HPE 3PAR Operating System offers industry-leading ease of use through a simple, unified
InForm Management Console and an extremely powerful, scriptable InForm Command Line Interface
(CLI). Manage your entire utility storage deployment from a single window, including remote
replication to disaster recovery sites. The 3PAR Remote CLI gives you powerful customization
capabilities that are simple to configure, eliminating the need for extra tools and consulting. Open
administration support is provided via SNMP and the Storage Management Initiative Specification
(SMI-S).
