HPE 3PAR Architecture

Intelligent, Tier-1 Storage for a hybrid cloud world

HPE 3PAR is AI-driven storage for proven Tier-1 performance and resiliency

Powered by AI, HPE 3PAR Storage offers a Tier-1 all flash foundation with the flexibility to move data seamlessly between on-premises and public cloud. Built to meet the extreme requirements of massively consolidated cloud service providers, HPE 3PAR Storage is ideal for mission critical workloads that require the highest levels of resiliency. Start fast and stay fast at the speed of memory with intelligent storage that anticipates and prevents issues across the infrastructure stack.
All HPE 3PAR models are built on a single flash-optimized architecture, run the exact same HPE 3PAR Operating System, and offer a common set of enterprise data services. HPE 3PAR arrays can natively replicate and federate amongst each other without the need for any external replication or virtualization appliance. All models also offer features such as support for unification of block and file protocols and the use of spinning media to further optimize costs.
In addition, the HPE 3PAR 20000 Storage system features an eight-node-capable backplane that supports two to eight-controller nodes. This enterprise class of flash storage offers the flexibility to start with a few TBs and grow to over 20 PBs usable for massive consolidation. The HPE 3PAR 8000 and 9000 Storage systems feature a quad-node-capable architecture which eliminates the tradeoffs associated with most midrange storage solutions. Dual controller architectures suffer from "cache write through mode" with the loss of a controller. In this scenario, writes are not signaled complete to the host until the data is on the backend disk which significantly impacts performance.HPE 3PAR systems with 4 nodes or more maintain high and predictable service levels even in the event of a cache or controller node failure by avoiding cache write-through mode.
