Data transfer techniques: SAP supports various data transfer techniques to transfer the legacy, parallel processing data into SAP System. It support various interfaces to communicate with SAP and Non-SAP System.

Continuous Support: SAP provides continuous improvement to existing software by releasing patches, packages, support stacks, upgrades and enhancement packages etc.

Best practices / Business Configuration sets: SAP provides are configured scenarios, solutions, building blocks and best practices to accelerate the implementation of SAP. Global best practices reduced cost, risk time.

High availability: It supports all the high availability services of cluster / backup / restore / recovery / standby and disaster recovery solutions.

Optimal response time: It provides optimal response time of 600millisonces to 2 seconds for each step (request through a mouse – click/keyboard stroke like f1, f2, f5, f8 and Enter.

Business Innovation: SAP provides my SAP Business suite business innovations 2011 which comprises of SAP ERP (SAP enterprise resource planning), SAP SRM SAP suppliers relationship management), SCM (supply chain management).

Netviewer: SAP provides a common platform netweaver to install all the required components in a single system (enterprise portal, exchange infrastructure, business intelligence, mobile infrastructure development. Infrastructure can be installed along with ERP system at one step).

Risks:

1. OS/ DB/SAP compatibility with hardware 
2. OS and Hardware Enterprise 
3. Network bandwidth and data transfer rate 
4. SAP support licensing and compatible software 
5. Onsite and Offshore communication 
6. Existing data centre team support and availability 
7. Take backup and restore capability

Hardware: It is a computer hardware in that facilitate various input and output devices to handle the user request and display or output the response to a monitor or printer.

CPU (Central Processing Unit): It is used to process the request by allowing a dedicated or shared process ID/thread ID to the user. The processor power is measured by using mhz/ghz to provide high availability dual/ multiple CPU all installed for failover and load balancing.

Each vendor CPU speed differs from model to model (DELL, IBM, HP)

• CPU can be monitored on windows by using task manager
• CPU is monitored on Linux by using command "top"
• CPU is monitored in SAP system by using transaction "ST06"
• CPU fetches the data into memory and holds as long as it is committed or rollback
