HP P10000 3PAR Architecture Basics

• Same underlying architecture as T-Class• Cache coherent & massively load balanced

• Mixed workload• Thin Built-In

• Architectural enhancements• Full 64-bit HW and SW• Gen4 ASIC• PCIe Bus (node motherboards)

• 1GB Chunklets• T10 DIF

• Common OS and same advanced HP 3PAR software

3PAR Concepts Overview

• PD (Physical Disk)

• Chunklet

• Wide Striping

• Virtual Volume

• Set Size

• Step Size

• Allocation Unit Size

• Virtual LUN

• CPG (Common Provisioning Group)

• Region

• Host

• VV Set, Host Set, (Autonomic Group)

• Inform Management Console (IMC)

*There will be a quiz.

Physical Disk – Chunklets (256 MB)

C = 256 MB Data Chunklet

SC = 256 MB Spare Chunklet

Physical Disk

Each InServ Physical disk is initialized with data chunklets and spare chunklets

Why are Chunklets so Important?

• Same drive spindle can service many different LUNS, and many different RAID types at the same time

• Enables array to be managed by policy, not by administrative planning

• Drives up utilization rate of the disks (no leftover space)

• Improved High Availability and Sparing

• Enables easy mobility between physical disks, RAID types, service levels

SW architecture: rapid, tailored provisioning...

Common Provisioning Groups (CPG)

• CPGs are FUNDAMENTAL to administering 3PAR.• CPGs automatically provision Logical Disk capacity on demand• CPGs are the combination of a RAID type and a drive type

which equals SERVICE LEVEL and AVAILABILITY LEVEL.• CPGs have many functions:

• They are the policies by which free chunklets are assembled into logical disks.

• They are a container for existing volumes and used for reporting• They are the basis for service levels and our optimization products.


3PAR Software Overview

Adaptive Optimization

• Collects sub-volume region level access data from array

• Allows creation of policies for schedules, tier definitions

• Analyses data and initiates region movement

• Generates reports for Adaptive Optimization

Recovery Manager

• Traditional tape backup solutions find it almost impossible to complete backup and recovery within required time frames

• Competing Snapshot technologies cannot meet the granular recovery points due to limited number of snapshots supported

• Complex and Expensive– Often requires professional services

– Increased Capacity requirements
