The HP 3PAR StoreServ System is a scale-out storage system that consists of several generational models.  The most recent models are the 9000 and 20000 systems.  Block access is supported on the 3PAR system using what HP calls ‘Personas’ which are embedded software instances within the 3PAR system. A file persona provides NAS capability with the StoreServ.  HP offers the 3PAR StoreServ 20000 as a high-end system with the same underlying architecture and embedded system software as the 9000.  The 3PAR StoreServ 9000 has a single, all-flash model, the 9450.

HP 3PAR’s design is a scale-out architecture using standard components grouped into multi-node clusters.  Each cluster of at least two controllers contains essentially three elements – host connectivity, cache and processing and back-end device connectivity. The clustered controller design allows the system to scale from two controller nodes up to an eight-controller configuration non-disruptively in the largest configuration.  Together, a pair of controllers as a node comprises four EIA rack units in a standard 19-inch cabinet.  Each controller pair provides full redundant failover and data access capability, with each controller being hot pluggable for serviceability.

Each controller in the storage system runs its own version of HP 3PAR’s proprietary InForm operating system which communicates with the others for redundancy and data movement.  The 3PAR StoreServ uses a 5th generation ASIC for storage processing including thin provisioning. The components of the HP 3PAR Storage Systems include:

  • Controller Nodes
  • Drive Chassis
  • Host and Drive Chassis Adapters
  • InForm operating system

Adaptive Flash Cache allows use of any installed SSDs as read cache extensions for DRAM and for controller add-in PCIe Optane (SCM) cards using NVMe protocol.

HPE Adaptive Data Reduction includes deduplication of data as part of an overall data reduction collection along with zero detect, data compression, and data packing.  Deduplication includes zero page elimination, thin provisioning along with snapshots and clones, and deduplication of data done inline.  Deduplication is done on a 16KB granularity for selected volumes designated as TDVV (thin deduped virtual volumes).  The 3PAR hardware ASIC is used to perform the hash code of the 16KB block, a bit for bit compare of data, and zero detect.  A feature called 3PAR Express Indexing does the initial table lookup of the hash code for detection of duplicate blocks.

Data compression uses functions of the Intel processor along with software to reduce data stored.  Data Packing uses 16KB containers to store data independent of block boundaries for greater efficiency.  With the Adaptive Data Reduction feature, HPE guarantees a 4:1 data reduction.
