New HPE 3PAR StoreServ 8000 and 20000 series – Optimized for Flash
AGENDA
•
HPE 3PAR StoreServ architecture fundamentals
•
HPE 3PAR Flash optimizations
•
HPE 3PAR portfolio overview
•
HPE 3PAR Flash – example from practice
•
HPE RMC – Next generation backup
MULTICONTROLLER 3PAR ARCHITECTURE HPE 3PAR Architecture •
Unlike most traditional architectures, limited to only 2 controllers, HPE 3PAR architecture can hold up to 8 controllers (depending on the model).
•
All controllers are active on all LUNs
•
Such an architecture can cover wide range of customer needs form low midrange up to high-end.
•
Single architecture (from entry 8200 up to high-end 20850 model), runs the exact same HPE 3PAR Operating System and offer a common set of enterprise data services,
Cost-effective, scalable, resilient, meshed, active-active … … and meets cloud-computing requirements for efficiency, multi-tenancy and autonomic management.
Traditional Architecture
Cost-efficient usually active/passive or active/optimized … … but dual-controller design limits scalability and resiliency.
HP 3PAR Gen5 Thin Express ASIC • The HPE 3PAR StoreServ 20000 and 8000 systems use the fifth and latest generation of the HPE 3PAR ASIC, the HPE 3PAR Thin Express ASIC. The HPE 3PAR Thin Express ASIC is engineered and designed for solid-state performance. • It works in parallel with the CPU, evenly processing the I/O workload across the node Active—Mesh scale—out architecture, ensuring lower latency resulting in better system bandwidth • Thin Express ASIC offloads some compute intensive tasks from Controller node CPU
Thin & SHA256 based Dedupe Built In Zero & Duplicate Block Detection for Block & File
Fast RAID 5/6 and Rapid RAID Rebuild Integrated XOR Engine
Tightly-Coupled Cluster 2x inter-ASIC Bandwidth, Low Latency Interconnect achieves write latency <200us
Mixed Workload Independent Metadata and Data Processing
Data Integrity T10 PI – Persistent Checksums

Flash optimizations
3PAR Hybrid storage optimizations –Adaptive Flash Cache – Leverages portion of SSD capacity as Read Cache extension – Does not require dedicated SSD disks – Can be simulated
–Adaptive Optimization – subLUN level tiering – Can use up to 3 tiers – You can schedule data movements and performance monitoring periods – Can be simulated
HDD vs Flash
Addressing Flash challenges – media endurance Wide striping
• Equal data distribution contributes to equalizing data writes across available media • With distributed sparing, no drives are left idle (spares contribute to wear leveling)
