HP 3PARFull and Virtual Copy

© Copyright 2011 Hewlett-Packard Development Company, L.P. The information

contained herein is subject to change without notice. Confidentiality label goes here

Part of the base InForm OSHP 3PAR Full Copy – Flexible point-in-time copies

3PAR Full Copy

– Share data quickly and easily

– Full physical point-in-time copy ofbase volume

– Independent of base volume’s RAID

Base Volume


– Independent of base volume’s RAIDand physical layout properties formaximum flexibility

– Fast resynchronization capability

– Thin Provisioning-aware• Full copies can consume same physical

capacity as Thin Provisioned base volume

HP 3PAR Virtual Copy – Snapshot at its best

3PAR Virtual Copy

Base Volume 100s of Snaps…

– Smart• Promotable snapshots• Individually deleteable snapshots• Scheduled creation/deletion• Consistency groups

– Thin• No reservations needed

…but justone CoW

Up to 8192 Snaps per array


Integration withOracle, SQL, Exchange, VMware

• No reservations needed• Non-duplicative snapshots• Thin Provisioning aware• Variable QoS

– Ready• Instant readable or writeable snapshots• Snapshots of snapshots• Control given to end user for snapshot

management• Virtual Lock for retention of read-only snaps

HP 3PAR Virtual Copy – Snapshot at its best

– Base volume and virtual copies can be mapped to different CPG’s

This means that they can have different quality of service

characteristics. For example, the base volume space can be derived

from a RAID 1 CPG on FC disks and the virtual copy space from a

RAID 5 CPG on Nearline disks.

– The base volume space and the virtual copy space can grow


– The base volume space and the virtual copy space can grow

independently without impacting each other (each space has it’s

own allocation warning and limit).

– Dynamic optimization can tune the base volume space and the

virtual copy space independently.

storage arrays

Pros

– Less expensive

– Minimized failure domains

– Simpler administration

Cons

– No heterogeneous array support

appliances that hierarchically control a

set of heterogeneous storage arrays

Pros

▸ Broader, heterogeneous array support

Cons

▸ More expensive (dual controller layer)

▸ Additional failure domains

▸ Lowest common denominator function

▸ Likely additional administration

3PAR and Oracle


3PAR + Oracle

• Wide striping + Thin Provisioning + ASM

• ASM Storage reclamation utility + 3PAR Thin Reclamation

• Recovery Manager for Oracle


Performance vs number of volumes

• High performance can beachieved with smallnumber of LUNs

• Instead of managing 10sof LUNs in ASM diskgroupto maintain highestperformance only fewLUNS are needed


performance only fewLUNS are needed

• In this example, maxperformance can beachieved with only 4 LUNs

3PAR + Oracle performance measurements

– Does 3PAR’s implementation of massive

parallelism of system resources (disks, paths,

port, cache,nodes, etc.) really assure service

levels as you scale? Yes!

– Is contention actually reduced by this

complete and automatic load balancing?

Absolutely!


3PAR + Oracle – Thin provisioning performance


3PAR RAID performance sensitivity


ASM with ASRU

HP 3PAR Thin Persistence – OracleIntegration

• Oracle auto-extend allows customers to save on

database capacity with Thin Provisioning

• Database Capacity can get stranded after

writes and deletes

• 3PAR Thin Persistence and Oracle ASM

Storage Reclamation Utility (ASRU) can reclaim

25% or more stranded capacity

25% or more stranded capacity

− After Tablefile shrink/drop or Database drop

− After a new LUN is added to ASM Disk Group

− Oracle ASM Utility compacts files and writes zeroes to free

space

− 3PAR Thin Built-In™ ASIC-based, zero-detection eliminates

free space

• From a DBA perspective:

− Non disruptive – does not impact storage performance.

ASIC huge advantage

• Unused space remains• Zeroes are written
