An Overview Of SAP HANA HardwareCategory: General, SAP BO on HANA, SAP BW on HANA Training, SAP HANA Training Posted:Dec 21, 2016 By: Robert
SAP HANA is defined as a compilation of software as well as hardware prepared to process huge real-time data utilizing In-memory computing. If you want to experience the entire support of this platform, it is essential to be familiar with its hardware infrastructure. When it comes to SAP HANA SP12 training, learning about SAP HANA Hardware will support to learn the course more effectively.
SAP HANA Hardware
The SAP HANA is restricted to be installed as well as configured only by the certified partners. HP, CISCO, HITACHI, FUJITSU, DELL, and NEC are some of the leading current Hardware partners of SAP HANA. Discover SAP HANA, which can speed the implementation, drives hardware, support to entry-level systems, storage solutions and appliances are some of the major things that are included in the list.
When it comes to the hardware, there is no wonder to state that there are more than 450 certified appliances. If you want to have a deep look at the Directory of Certified SAP HANA Hardware, just click here.
In addition to these appliances, it is potential to certify some sane config with Enterprise Storage such as EMC VMAX and Violin. It is also potential to utilize any Intel server for the non-production use-cases with any config. With these certifications, customers can enjoy fantastic flexibility. They can select the storage, vendor and networking of their own preferences. For some non-production situations, they can able to build systems that are more cost-effective. A major notable advantage is that the customer can get their production hardware appropriately provisioned. There is no doubt that incorrect hardware provision can be a costly mistake.
Ways To Scale SAP HANA
When it comes to scaling this framework into immense systems, there are two possible ways. They are scale up and scale out.
The scale-up system can build a single unit with several resources as possible. However, in the scale-out system, a number of smaller sockets are connected to a single cluster database. HANA is known as a shared architecture, hence, it is essential to have a shared storage for the purpose of data persistence.
SAP HANA need a Central Processing Unit to Random Access Memory ratio that is stable for production units. For SAP Business collection, it is fixed at 768GB per socket and for analytic use cases, it is fixed at 256GB per socket. Mainstream Intel units come with 4 to 8 sockets that mean Analytics customers can have the maximum of 2TB and Business suite customers can have the maximum of 6TB, with available hardware in a sole system.
Technical Architecture Of SAP HANA
The technical architecture of this powerful framework is very simple. The following are some of the components of the architecture:
It is based on Westmere EX platforms or Nehalem EX platform of Intel. Since HANA is an immense rack-mount unit, which includes up to 8 CPUs and 80 cores. It is a service hardware, which you can purchase off the online. For example, the DELL PowerEdge R910 along with 1TB Random Access Memory costs around $65k on their official website.
Random Access Memory
There are plenty of RAM choices matched to the CPU of HANA system. For example, twenty cores permit 256GB Random Access Memory. 1TB of RAM costs around $35k approximately.
Fast Log Storage
A preferable choice is Fusion-io ioDrive Duo, though it is very expensive. In some settings, the data and log storage are shared. The latest release of Log storage is Fusion-io ioDrive 2, which is less expensive and faster when compared to ioDrive.
It is sized to 4x RAM. When compared to other certified single-node config, this is the cheapest SAS direct storage. With this data storage, it is possible to power down the utilizations and perform tasks like backups. 1TB storage system costs around $15 to 20 K. when it comes to multi-node config, it utilizes some sort of shared storage system.
Note that in addition to the budget of hardware, you need to consider the cost of installation service and support contract for the pre-built system, which is offered by the certified partners of SAP HANA.
Hardware Vendors Of HANA
Several different hardware vendors are offering the service on SAP HANA systems. Mostly all the vendors offer great services. The main difference among the partners can appear in the implementation quality offered by the service professionals. Keep in mind that poorly designed as well as maintained SAP HANA units will not function well.
If you want to use ultra-high-end use-cases, it is essential to consider specific things including better networking and SSD storage. If you want HANA appliances to perform extremely well, it is worth to build with Tailored Datacenter Integration. However, it is unnecessary for standard use-cases. In these days, SAP offers an open hardware platform hence, customers can choose the vendors from multiple choice based on their preference and requirements. Fujitsu, IBM, HP, and Dell are the recommended vendors for better performance.
