HP 3PAR Persistent Cache
HP 3PAR Persistent Cache is a resiliency feature built into the HP 3PAR OS that allows "always on"
application and virtual server environments to gracefully handle an unplanned controller failure.
Persistent Cache eliminates the substantial performance penalties associated with traditional arrays and
"write-through" mode so that 3PAR StoreServ Storage Servers can maintain required service levels even in
the event of a cache or controller node failure. HP 3PAR Persistent Cache leverages the clustered HP 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 HP 3PAR arrays, including StoreServ 7400 and the InServ F400-making 3PAR HP the only vendor to
incorporate this industry-leading service level protection capability into midrange as well as high-end
arrays.
HP 3PAR RAID MP (Multi-Parity)
HP 3PAR RAID MP (Multi-Parity) introduces Fast RAID 6 technology backed by the accelerated performance
and Rapid RAID Rebuild capabilities of the 3PAR ASIC. 3PAR RAID MP is supported on all InServ StoreServ
models and delivers extra RAID protection that prevents data loss as a result of double disk failures. RAID
MP delivers this enhanced protection while maintaining performance levels within 15% of RAID 10 and
with capacity overheads comparable to popular RAID 5 modes. For this reason, 3PAR RAID MP is ideal for
large disk drive configurations-for example, Serial ATA (SATA) drives above 1 TB in capacity.
HP 3PAR Rapid Provisioning
The HP 3PAR OS eliminates array planning by delivering instant, application-tailored provisioning through
the fine-grained virtualization of lower-level components. Provisioning is managed intelligently and
autonomically. Massively parallel and fine-grained striping of data across internal resources assures high
and predictable service levels for all workload types. Service conditions remain high and predictable as the
use of the system grows or in the event of a component failure while traditional storage planning, change
management, and array-specific professional services are eliminated.
HP 3PAR Scheduler
HP 3PAR Scheduler also helps automate storage management, reduce administration time, and decrease
the chance of administrative error. Scheduler does this by giving users full control over creation and
deletion of virtual copy snapshots-a process that is now completely automated with HP 3PAR Utility
StoreServ Storage. When used in conjunction with Autonomic Groups, HP 3PAR Scheduler automates
virtual copy snapshots across multiple boot and data volumes with full write consistency across all these
different volumes.
HP 3PAR Thin Copy Reclamation
An industry first, Thin Copy Reclamation keeps your storage as lean and efficient as possible by reclaiming
unused space resulting from deleted virtual copy snapshots and remote copy volumes. Thin Copy
Reclamation is built on a virtualization mapping engine for space reclamation called HP 3PAR Thin Engine,
which is included as part of the HP 3PAR OS.
