Key Points discussed in this webinar are: 1.How dynamic simulation can replace traditional network simulations that are slow and lack configuration and visibility to analyze performance. 2.How to avoid over or under design, cost increases, and delays. 3.How an architectural model can be used to test the capacity and power requirements of your data center or your server.

6. Sizing Data Centers Today
Current and
Future SLA
Get Current Configuration
with usage estimates
Add more servers
for future needs
Create configure using
experience, articles
and references
Try to fit more
customers

7. Challenges with Current Approach
Budget planning is difficult
◦ Limited visibility into operating expenses and system utilization prior to usage
Capital expense is based on “build-and-they-will-come” model
◦ Need to invest in expensive equipment, software licenses and performance measurement software
Scalability means adding more servers
◦ Sharing requires good quality load distribution based on anticipated work loads
Missing out on revenue opportunities
◦ Reuse floor space, power connection and existing hardware

Which architecture is better suited
for our data center?

9. Migrate to a Reliable and Accurate
Method of Data Center Design
Simulate the theoretical and analytical studies for network topologies, traffic distributions,
scalability, and load balancing
Graphical prototype of the proposed data center or colocation site
Setup attributes for the communication, computation, storage and software
Analyze the measured statistics and reports
System sizing to meet SLA and profitability requirements
Optimize to ensure highest efficiency

10. Concept of a Server System Modeling
Applications are a set of Complex tasks
- Variable rate input stream and task
dependency
Contention between resources and tasks
- Task assignment and sequence
Trade-off between process and transfer
- Reduce buffering and latency with minimal
transfer time

12. Use Generated Reports to Make Decisions
Reports can cover network latency, hardware efficiency, power, reliability and throughput

13. Advantages with Data Center Modeling
Gain valuable insights into the data center operations before deployment
◦ System efficiency, operational cost, Bill-of-materials
Projections for investments based on SLA, workloads and migration to cloud
◦ Get accurate measurements for each configurations
Simplify system complexity
◦ Explore consolidation using VM, reduce device count and try different load distribution algorithms
WorldView
◦ Simulating multiple data centers and distribution traffic by distance, dynamic usage and response time

14. Key terms in System Modeling
Architecture Exploration
◦ Optimize and validate the system specification
◦ Specification: Processor speed, topology and arbitration
◦ Requirements: Timing, energy, cost, weight and efficiency
Performance Analysis
◦ Buffer size, utilization, throughput and response time
Power Measurement
◦ Peak and average power, energy and power/task
Functional Correctness
◦ Arbitration, software task scheduling and task graph
Failure Analysis
◦ Hardware, Software, network, data, power and logic
Making Better Quality Products

15. Sizing Data Centers of the Future
Current and
Future SLA Data center model of
Servers, storage,
software and interfaces
Simulate Requirements

Optimize for energy
cost, latency and
throughput
Feedback changes in
traffic, applications and
security

17. How does Modeling and Simulation of
Data Center Architecture Work?
Use SLA and Future plans
◦ Goal input for the model
Construct a model
◦ Communication: Interfaces and multiple data center locations
◦ Hardware: Storage, processor (cores), memory
◦ Inter-process communication: Task graph to show the relation between requests, applications and mapping to hardware
◦ Software: VM,OS, Application
◦ Licenses: Number of instances
Add workload and application
◦ Add the traffic stimulus as traces, distribution or custom patterns
View reports
◦ Match metrics against the goals to select the most suitable configuration
Test
◦ Failures, traffic overload and loss of hardware/interfaces
