1 TB = 1000 x 1000 x 1000 x 1000 bytes.

2 - Actual space available for a database after mirroring (ASM normal redundancy) and leaving one empty disk to

handle disk failures. Capacity calculated using normal space terminology of 1 TB = 1024 * 1024 * 1024 * 1024 bytes.

3 - Actual space available for the database computed after triple mirroring (ASM high redundancy). Capacity

calculated using normal space terminology of 1 TB = 1024 * 1024 * 1024 * 1024 bytes.

Exadata for SAP

Overview


Recent Study of SAP Users (By Compuware)


Exadata is Best for SAP

Best Availability

Best Consolidation

Best Security

Highly Engineered and Standardized


SAP ERP

Exadata for Database Consolidation

• Consolidation is key to reducing costs

• Administration, hardware, software, data center

• Many databases can be consolidated on Exadata

• Multiple small databases within a node

• Large databases can span nodes using RAC

• Exadata delivers extreme performance for

complex workloads that mix OLTP and DW

• Complex OLTP: SAP ERP, SAP CRM etc.

• Transactions, batch, reporting, documents

• Complex Warehousing: SAP BW

• Multiple databases running different applications

SAP BW


Consolidate Database Storage

• Exadata and ASM allow all storage servers to be

shared across databases

• Shared Configuration

• Advanced ASM data striping spreads every

database across all storage servers

• Eliminates hot-spots and captive unused space

• Full storage grid performance available to all

databases

• Database or cluster level storage security

• Predictable Performance

• Exadata I/O resource manager prioritizes I/Os

to ensure predictable performance

• At user, job, application, or database level

• No need for isolated storage islands

Exadata Storage Software Unique Features

• Exadata Smart Scans

• Up to 10X or greater reduction in data sent to database servers

• Exadata Storage Indexes • Eliminate unnecessary I/Os

• Hybrid Columnar Compression1) • Efficient compression increases

effective storage capacity and increases user data scan bandwidths by a factor of up to 10X

• Exadata Smart Flash Cache • Breaks random I/O bottleneck by

increasing IOPs by up to 30X

• Doubles user data scan bandwidths

• I/O Resource Manager (IORM) • Enables storage grid by prioritizing

I/Os to ensure predictable performance

• Quality of Service (QoS)

• Actively meet and maintain SLAs

• Memory Guard to protect existing

current transactions from memory-

based failures

1) Hybrid Columnar Compression can be used for SAP but alignment with SAP is required


Best and Fastest SAP Availability

Backup

• Super Fast Tape or Disk Backup

• Incremental backup is 10x faster

• Compressed data another 3x

• RAC protects against node failures

• Data Guard protects against Data

failures and Disasters

• ASM protects against storage failures

• Flashback protects against user errors

• Enterprise Manager

• Manage & administer Database and ASM

• Monitor the Exadata Database Machine Hardware

• Plug-ins to monitor the Exadata Storage Cells and other

components in the Database Machine

• Auto Service Request (ASR)

• File SRs automatically for common hardware faults

• Comprehensive CLI

Exadata for SAP

Pre-requisites


Requirements for SAP with Exadata Database Machine

• Exadata database node:

• Oracle EE 11.2.0.2 and higher

• Oracle Linux 5 or Solaris 11 Express (customers will choose their preferred

Database server OS at installation time)

• Database character set:

• WE8DEC for non-Unicode SAP systems

• UTF8 for Unicode SAP systems

• Database data stored on ASM only

• Exadata storage server: Oracle Linux 5 only

• SAP version: SAP NetWeaver 7.x (SAP systems on Kernel 7.x)

• Application server

• Oracle Linux 5 and Solaris x86 (certified only with UNICODE SAP systems)

• Other certified platforms e.g. RedHat, Suse Linux, Windows and other UNIX OS

• 3 tier configurations



Exadata for SAP

Migration Path


Migration to Exadata

How to migrate from your current Oracle Database into

Exadata for SAP?

Possible Migration methods:

• R3Load

• Transportable Tablespaces

• O2O (Oracle to Oracle DB Migration)

• O2O Online / “Triple-O” (OGG)




Exadata for SAP

Implementation Example

Workload balancing with Exadata for SAP

5 SAP Appl. server

2 RAC nodes

These two figures show how the workload can be balanced on the application servers, thus

on the RAC nodes. SAP and RAC scalability fit well to each other


5 SAP Appl. server

4 RAC nodes

Business Continuity with Exadata for SAP after

RAC Nodes crash


Why is Exadata So Fast?

• Scaling-out & Parallelization of Tasks

RAC

multiple storage servers are processing one query in parallel

SAME (stripe-and-mirror-everywhere) principle with ASM

• Extensive Use of Flash Cache (NAND on PCI cards)

minimizes physical disk IO

overcomes disk controller bottlenecks

• High-Throughput / Low Latency Network

between storage & database servers

speeds-up Global Cache communication (RAC)

• Exadata Data Storage Software

delegates parts of the processing to the storage layer

intelligent / application-aware use of flash
