SAP HANA – composite post

As I started similarly with SAP BW 7.3 I try to collect all relevant information sources about in this case SAP HANA here. BTW: What’s HANA? In short it is in-memory solution from SAP. It stands for High-Performance Analytic Appliance and basically it is appliance (plus its software components) that can absorb large volumes of data (e.g. tera bytes) into its “operational” memory. The reason why it is so high performant is that all the data is in memory not stored in hard drives. It can be set up on top of SAP ERP or BW system (plus non SAP databases) without necessity to materialize data via transformations as in contrary to current DWH solutions. HANA bundles several components: in-memory computing engine, real-time replication service, data modeling and data services. As it is delivered as appliance it is depended currently on few vendors are supported: Fujitsu, HP, IBM.

Basically we can say that HANA successor of SAP NetWeaver BW Accelerator as moving forward into in-memory computing. Here HANA acts as persistence mechanism for SAP NetWeaver BW.

HANA components:

1. The core of HANA is called SAP In-Memory Computing Engine (IMCE or ICE, also called as NewDB or BAE). It is an engine kind of in memory database which uses row/column/object based database technology to store data. It is for parallel data processing using state-of-the art CPU possibilities.

2. HANA Studio (client app, or Studio Repository, Eclipse based editor connected to a HANA
Server backend) consists of:

    2.1 Administration console - administer and monitor database
    2.2 Information modeler - data modeling
    2.3 Lifecycle mngt - provides an HANA stack update using SAP Software Update Manager (SUM)

3. HANA Load Controller -resides in SAP HANA, coordinates the entire replication process: It starts the initial load of source system data to the IMDB in SAP HANA, and communicates with the Sybase Replication Server to coordinate the start of the delta replication

4. Host Agent -handles login authentication between source system and target system

5. Sybase Replication Server -accepts data from Replication Agent, distributes and applies this data to the target database using ECDA/ODBC for connectivity.

See complete typical HANA components: Implementing SAP HANA

Current versions:
SAP HANA 1.0 SP02 - as of 12th June 2011 in general availability

Operating system: //only following one:

64-bit SuSE Linux Enterprise Server (SLES) 11 SP1 operating system

Upcoming version:
Nov 2011 - SAP starts rump up program for their customers to run BW on HANA as its database

 Success (customer) stories: 
 Where to practice HANA? 
  • SAP Developer Center @ SDN: access to hosted HANA sandbox systems - currently beta version.
  • Get the project:  be lucky enough to get into customer who is running HANA project. Unfortunately there are still only few of them.
  • SAP Mentors: If you are a SAP Mentor then you have an access to SAP HANA Developer Access Beta program. It is an access to where are virtual machines/images with HANA software (HANA Editor).

Nice article. We have created a spatial operating with microsoft kinect, augmented reality and SAP HANA. Would be interested to hear your thoughts.

Hi William,

yep, very interesting. It is so amazing what today's technology achieved. Even thought HANA is not that important in this case it is another possible usage of HANA.

Thanks for sharing, sapper
