SAP HANA 2.0 Architecture

I will explain how to configure the architecture of the HANA Database.
When constructing the HANA DB, I will explain the representative methods in various ways with the pictures. I will explain S / 4 HANA and HANA DB 2.0 more specifically. You will be wondering how to configure HANA DB 2.0, the database that makes up S / 4 HANA. You need to build S / 4 HANA for your investment and your company’s situation. You need to consider high availability and think about disaster recovery. Let’s take a look at the various options to build the S / 4 HANA most effectively considering the cost of investing in the company.

To build HANA DB 2.0, there are 7 kinds. Of course, if you go into detail here, you get more choices and can distinguish more than seven. In this section, I will explain seven things.

  • SAP HANA Classical Standard Architecture
  • SAP HANA H/W Server Partition(IBM LPAR)
  • SAP HANA Multiple Components One System(MCOS)
  • SAP HANA Multiple Components One Database(MCOD)
  • SAP HANA Multi-Tenant Database Containers(MDC)
  • SAP HANA Virtual Machine(VMware)
  • SAP HANA Cloud, AWS, Microsoft Azure

  1. SAP HANA Classical Standard Architecture

The HANA Classical Architecture is the most common and has a lot of structure in general companies to date.

One server, one database, one DB Schema, and one S / 4 HANA Application. It is the simplest, easiest and easiest structure to construct.

Since one S / 4 HANA application uses all H / W resources (CPU, Memory) on its own, CPU and Memory can be used by one application at maximum. It is a structure that can use H / W resources without interference of other applications. H / W cost is high for independent H / W configuration.

  • The most common structure (simple and easy to configure)
  • 1 H / W, 1 HANA DB, 1 DB Schema, 1 S / 4 HANA application
  • SID configuration of each HANA DB
  • Uses a single application to maximize hardware without interfering with other applications
  • H / W cost increases

  1. SAP HANA H/W Server Partition(IBM LPAR)

The HANA H / W Server Partition is most commonly applied to IBM LPARs.
The basic concept of the virtual machine that is mainly used now comes from IBM LPAR. It is a concept to separate physical H / W, but CPU,
It is a structure that uses memory alone and not shared. H / W box is used together, but CPU and Memory are not shared. The advantage of this configuration is the same configuration as Classical configuration, which can reduce the physical space, and one S / 4 HANA application is a common configuration using CPU, Memory alone. However, the difference is that we use a hybrid H / W BOX together.

  • Configuration dependent on hardware vendor (IBM, Hitachi)
  • 1 H/W, 1 HANA DB, 1 DB Schema, 1 S/4 HANA application
  • SID configuration of each HANA DB
  • Uses a single application to maximize hardware without interfering with other applications
  • H/W cost increases

 

  1. HANA Multiple Components One System(MCOS)

HANA Multiple Components One System (MCOS). It is composed of one HANA DB in one H / W, several DB Schema, several S / 4 HANA, BW / 4 HANA and so on.
The primary reason for this configuration is to reduce costs. In order to minimize the cost and maximize the effect, the configuration differs from the following Multi-Tenant Database Containers (MDC) and Multiple Components One Database (MCOD). This configuration is not recommended for production environments because it uses one H / W CPU and memory.
Performance is deteriorated because it is shared with several applications (S / 4 HANA, S / 4 BW, etc.) and CPU and Memory.

  • Two HANA DBs in one H/W, two DB Schema, two S/4 HANA applications
  • Reduce costs by using two HANA DBs in one H/W
  • Likelihood of performance degradation by sharing CPU and memory resources of the same H/W
  • SID configuration of two different HANA DBs in one H/W
  • Not available for production (due to performance and other application impact)

  1. HANA Multiple Components One Database(MCOD)

The HANA Multiple Components One Database (MCOD) uses one HANA DB, two DB schemas and two S / 4 HANA applications in one H / W. MCOD is the term used before HANA 2.0 Tenant DB came out and is very similar to Tenant Database Containers (MDC). It’s a similar concept, with different concepts coming out. The difference is that HANA DB is used together. CPU / Memory, which is the same hardware resource, may be shared, which may result in performance degradation. The main reason to configure MCOD is cost savings. Since one HANA DB is used for one H / W, the labor required for cost and management is reduced. HANA DB is shared and used, but management cost is reduced. When HANA DB is shut down, both applications are stopped. CPU and memory resources can be shared, which causes performance degradation, and HANA DB shutdown causes other applications to stop.

  • 1 H/W, 1 HANA DB, 2 DB Schema, 2 S/4 HANA applications
  • Concepts used before HANA Multi-Tenant Database Containers (MDC)
    (Still a valid concept in Oracle DB)
  • Cost reduction by using 1 HANA DB for 1 H/W
  • Likelihood of performance degradation by sharing CPU and memory resources of the same H/W성
  • SID configuration of one HANA DB in one H/W
  • Using the same HANA DB Software Version
  • Not available for production (performance and same DB sharing)

  1. HANA Multi-Tenant Database Containers(MDC)

MDC (Tenant Database Containers) consists of one HANA DB in one H / W, several DB Schema and several S / 4 HANA applications. HANA Multi-Tenant Database Containers (MDC) is a Tenant DB for HANA DB released from HANA 2.0 SPS01.

HANA 1.0 and HANA 2.0 SPS00 are default Single Container System.

Since HANA 2.0 SPS01, the default is Tenant Database System. HANA 1.0 SPS09 first started supporting Tenant Database Containers (MDC). Tenant Database Containers (MDC) and Multiple Components One Database (MCOD) are similar concepts. They are expressed as MDC (Tenant Database Containers) when HANA DB 2.0 is released. MDC is mainly dealt with when terminology is HANA DB. (SAP Note 2096000, 2423367)

  • 1 H/W, 1 HANA DB, 3 DB Schema, 2 S/4 HANA applications
  • Basic Tenant DB is provided after HANA 2.0 SPS01
  • Cost reduction by using 1 HANA DB for 1 H/W
  • Likelihood of performance degradation by sharing CPU and memory resources of the same H/W
  • SID configuration of one HANA DB in one H/W
  • Use the same HANA DB Software (using the same HANA Software Engine)
  • Can be used for production (Note 1661202) However, but S/4 HANA and S/4 BW can not be used together in the operating environment

  1. HANA Virtual Machine(VMware)

HANA Virtual Machine (VMware) is a virtualization solution that consists of installing multiple Operating Systems (OS) on one H/W to form an S/4 HANA application.

HANA 1.0 SPS05 is now the first VMware Hypervisor support.

Hypervisor is a virtualization layer that exists on a physical H/W server and provides CPU, Memory, H/W for operating system (OS)

Two OS(Operating System) are installed in one H/W, two DB schemes in two HANA DBs and two S / 4 HANA applications. The main reason for this configuration is the reduction in cost and the area to manage. Virtualization is going on in Windows server, HANA DB is installed in LUX, and SAP HANA DB can be installed and configured in virtualization (VMware). In general, the company has been considering how to reduce dozens or hundreds of servers, and the introduction of virtualization has resulted in a reduction in the number of physical H/W servers. As the H/W Box decreases, the cost will decrease and the administrative costs associated with it will also decrease, so there is nothing better for the company (see SAP Note 1788665, 2652670).

  • 2 HANA DBs, 2 DB Schema, 2 S/4 HANA applications on 1 H/W and 2 OS
  • First time virtualization (VMware Hypervisor) support in HANA 1.0 SPS05
  • Reduce H/W cost by two OS configurations on one H/W
  • Likelihood of performance degradation by sharing CPU and memory resources of the same H/W
  • SID configuration of two HANA DBs in one H/W
  • Available for Production (VMware vSphere 5.5 or later)

  1. Cloud type(HANA Cloud, AWS, Microsoft Azure)

SAP’s Public Clouds include Amazon Web Services (AWS), Microsoft Azure, IBM Cloud, Google Cloud Platform, and Oracle Cloud.

Here is a brief summary of the cloud and the cloud provided by HANA.

Cloud provides three service models (Service Model)

  • IaaS(Infrastructure as as Service)
  • PasS(Platform as a Service)
  • Saas(Software as a Service)

Cloud Deployment Model

  • Public Cloud
  • Private Cloud
  • Hybrid Cloud

 

Three Service Models provided by the cloud

  • IaaS(Infrastructure as a Service) : Providing basic storage and computing power (CPU, Disk, etc.), paying as much as using infrastructure resources such as servers, storage, and networks

Offered service name :  Amazon EC2, S3, Microsoft Azure, Google Cloud, IBM Cloud etc.

It is the most basic category of cloud computing services. With IaaS, you lease IT infrastructure from servers, VMs (virtual machines), storage, networks, and operating systems on a per-volume basis from cloud providers.

  • PasS(Platform as a Service) : A way for developers to provide a computing platform to develop, test and run their own applications.

PaaS is designed to make it easier and faster for developers to create web apps or mobile apps without having to set up or manage the basic infrastructure of servers, storage, networks, and databases required for development.

Offered service name :  Goog App Engine, MS Azure, AWS

Offered service is Linux, Apache, PHP, MySQL, MS Azure, Goold Apps etc.

  • Saas(Software as a Service) :Service model made for the purpose of providing software or application, providing standardized application process

Offered service name :  Naver’s Ndrive, iCloud, Dropbox, Google Docs, MS Office 365 etc.

A way to provide software applications on-demand and on a regular subscription basis over the Internet. With SaaS, cloud providers host and manage software applications and underlying infrastructure, and handle maintenance such as software upgrades and security patches. Users typically connect to applications over the Internet using a web browser on a mobile phone, tablet, or PC.

Three cloud Deployment Models

  • Public) Cloud : Owned and operated by third-party cloud service providers that provide computing resources such as servers and storage over the Internet. Examples of public clouds are AWS and Microsoft Azure. With a public cloud, all hardware, software, and other support infrastructure is owned and managed by the cloud provider

Example) It is common to share a car such as Uber, which is famous for shared cars, or “Tada” which is a Cacao’s carpool.

  • Private) Cloud : Cloud computing resources that are used exclusively by a single business or organization. Private clouds can be deployed within your company’s physical onsite data center. Some companies also pay third-party service providers to host their private cloud. A private cloud is a cloud in which services and infrastructure are maintained on a private network.

Example) This is the business car used by the LG washing machine division.

  • Hybrid Cloud : Combine public and private clouds that are bound together as a technology that allows data and applications to be shared between a public cloud and a private cloud. Hybrid clouds allow you to move data and applications between private and public clouds, giving your business more flexibility, more development options, and optimizing your existing infrastructure, security and compliance.

Example) If you are going to work at the washing machine business and go to work, all of your business cars are in use. If you are using carpool “Tada” in Cacao, this is the case.
