Inside the Computing Engine of SAP HANA we have many different components that manage the access and storage of the data. This include MDX and SQL

access, as well as Load Controller (LC) and the Replication Server.

SAP HANA — Sizing the Application

A lot depends on actual compression rates, but here are some first stab quick “rule-of-thumb’ for size estimation

• Working memory RAM = (Source Data Footprint / 5) * 2

• SSD (Disk) Disk persistence = 4 * RAM Disk log = 1 * RAM

• CPU: 0.2 CPU cores / active user

To do accurate sizing you should contact your service partner and the hardware vendor you are working with and plan to spend some time getting the numbers right.

SAP HANA — Vendors and Appliance Options• The vendors that provide SAP HANA solutions include Cisco, Dell, IBM,

Intel, HP, and Fujitsu as of Jan 2012

• SAP HANA generally consists of: The database and database clients HANA studio (P2 repository) Load controller and Sybase replication server The host agent and LM structure files Op. Sys. configuration, SAPCAR & SAP JVM The update manager for SAP HANA

Moving BW to HANA

Normal duration is 6-12 weeks depending on size and number of environments. Key decisions are:

1. How many DSOs and InfoCubes to convert2. Risk avoidance and testing requirements3. High-availability requirements4. Size of system(s)5. Conversions requirements (using SLT, LC and data

services)6. Migration Vs. Clean install

The Work

1. Clean install vs. Migration of BW system2. Team for Install3. Team for Testing4. Deploying BusinessObjects5. Moving forward with BI-Self Service

SAP HANA — Loading the Application and Performance

You can load the application based on the logs in the source system, ETL-based (Extract Transform and Load) loads, and SAP trigger-based replication

Tool PurposeBusinessObjects Data Services 4.0 – ETL-based replicationSybase replication server & Load Controller – Log-based replicationSAP Landscape Transformation (LT) – Trigger-based replication

Log based replication is possible on IBM DB 2 LUW/UDB and planned for MSFT SQL Server Enterprise Edition, Oracle Enterprise Edition, and Sybase ASE (as of Dec. 2011) .
