IT Infrastructure: 100 X Better Every Decade

IT price-performance keeps doubling

Moore’s Law stated in terms of transistors

Exponential growth since 1900

Long before transistors invented

Slight acceleration in last 50 years

Now doubling every18 months

6+ doublings per decade

~100 X price-performance per decade

~10 BILLION X in last 50 years

An enterprise software architecture

can absorb a small number of

doublings

For about a decade, merely faster &

cheaper

After 100 X improvement, suddenly very

different

Network Product Certification by SAP

Network Solutions are pervasive components in SAP’s customer’s SAP landscapes

and their whole global IT operations.

Therefore SAP certifies the integration of network products with the SAP NetWeaver

platform.

Testing:

SAP’s Network Certification

Test consist out of two end-

user activity oriented and 2

SOA oriented scenarios.

Test methodology includes

functional checks as well as

high load and large object

tests

The network includes an

emulated WAN (Internet)

link.

General Pass Criteria: Preserve functional correctness of

the SAP application scenarios

Same or better performance of the

SAP application as without the

network product under test.

Secure, encrypted communication

over the WAN link.

For at least one test

scenario show at least one

Value Pass Criteria out of: improve performance improve or offload security

improve reliability and availability

Benefits for SAP customers: A list of network products which

have passed basic tests with SAP

applications.

Many network vendors enhance

their products for SAP customers

based on findings from joint testing

with SAP

Many network vendors provide SAP

application specific documentation

for their products to customers.

Lower TCO, better

support, overall enhanced

SAP application

experience.

AccAD for SAP NetWeaver or Generic

Optimizer?

Generic optimizer

+ Multi-protocol optimization: e-mail (SMTP), file sharing (CIFS), http web traffic, ...

+ Only one global acceleration network infrastructure for all purposes – no SAP-specific optimization, but

good results are possible

AccAD

+ Focus on http, https, & tcp extend generic web-application optimizations with SAP application-aware

focus and logic

+ Strong security support: SSL (with or without client certificates), complex landscape set-ups supported

+ Best acceleration practices for SAP / SAP Business Objects UI technologies

Using AccAD and a generic optimizer in parallel

- Duplicate network acceleration infrastructure, traffic redirection has to be set up properly between two

acceleration environments.

+ Flexible integration depending on existing setup (e.g. use AccAD for SAP only)

+ Provide the right acceleration for specific use cases best performance results for end users

AccAD on top of partner platforms

+ Share the same hardware (e.g. by consolidating hardware through virtualization)

+ Share and combine traffic redirection mechanism (e.g. leverage existing in-path deployment also for AccAD)

+ Provide the right acceleration for specific use cases best performance results for end users

+ Integrated deployment lower operation and maintenance efforts

(RiOS)

Riverbed Steelhead

Remote Office

Using AccAD on Riverbed Service Platform (RSP) allows customers to add SAP-specific

acceleration on top of Riverbed Steelhead

AccAD is used to accelerate SAP-application-specific traffic; Riverbed Steelhead RiOS is

used to optimize and accelerate other enterprise applications

RSP is used to deploy a virtual machine containing an AccAD Client Front End

Benefits:

Only one physical machine (Riverbed Steelhead) is required at the remote office

In-path deployment can be used as traffic redirection for Riverbed and AccAD

Only AccAD traffic is redirected to the AccAD VM

James Watt invented a regulator, which automated and

optimized Steam Engines operation and made them more

usable and 75% more fuel efficient. His inventions

helped to get the Industrial Revolution started.

Ref: http://en.wikipedia.org/wiki/James_Watt

Automation


Three Types of Simplifying SAP Application

Server Operations

Auto-configuration: Usually network IT staff and SAP application IT staff need to collaborate to configure an Application Delivery

service for an SAP system.

Idea: Query a central process in an SAP instance for all detailed information to configure a load

balancer for that SAP instance.

Auto-operation: When an SAP instance is scaled up or down through adding or stopping SAP servers an Application Delivery

component needs configuration adjustment.

Idea: Query a central SAP instance process for necessary configuration information periodically.

Auto-optimization: When the workload on an SAP changes the SAP system needs to scale up or down.

Idea: An Application Delivery solution sits in a sweet spot for detecting SAP performance. An AD could

derive from performance monitoring the information on when to scale an SAP instance up or down. Such

adjustments could be triggered by an AD and be executed with help of SAP’s Adaptive Computing

solution.

Steam Engine

The Steam Valve

As in a steam engine a self regulating system needs the following close loop control elements:

A controller which can detect the difference between a desired performance metric and the actual

performance metric and which receives control input from the engine through the ASLR API. The

difference is used to drive the steam valve which is the ACC in the SAP system. Performance metrics

could be end-user performance, Server CPU usage or similar. Either operational tools or ADCs with

performance monitoring capabilities might play the controller role.

Note: Such controlled, self adjusting systems are tricky. Depending on PID-controller amplification factors

undesired behavior might occur and break the engine.

Building a Controller Loop


Auto-configuration:

significantly reduced costs for configuring and testing a network Application Delivery solution for an SAP system.

Auto-operation:

Multiple time and cost savings:

– Reduction to zero human network administration time when the SAP Application Server deployment is changed.

– Reduction of need for organizational coordination between network and application IT teams.

– Reduced risk of operations errors, which could cause poor application performance and even unplanned downtimes of the SAP application.

Auto-optimization:

Same benefits as for Auto-Operation

Better SLA compliance of the application to business end-users through instant capacity adjustments for changing workloads and thus constantly good application performance

Going Green: Instant release of computing capacity under reduced workloads. Savings on cooling, power, capital costs…
