Performance of an applicationacross the WAN is always dependent on the latency.

Calculating Throughput

The equation never asks for the bandwidth size!


WE DID THE MATH FOR YOU!

• Extend distance• Correct packet loss• Increase bandwidth


APPLY 1 OR ALL 3 TECHNIQUES

THE SOLUTION

• NETWORK INTEGRITY

• FIX CONGESTION / PACKET LOSS• • Traffic Shaping/Quality of Service (QoS)

• • Forward Error Correction (FEC)

• Packet Order Correction (POC)

• NETWORK MEMORY

• INCREASE BANDWIDTH• Real-Time deduplication of all IP traffic

• TM

• NETWORK ACCELERATION

• EXTEND DISTANCE• Mitigate protocol latency and chattiness

*Latency is determined by:- Speed of light- Route taken- Congestion in network


ELIMINATE PACKET LOSS

12345P

Packet Lost

Lost Packet Rebuilt from Parity

• Parity dynamically adjusted based on amount of loss

• Lost packets rebuilt at the receiving Silver Peak

• Receiver unaware packet loss has occurred

• No window size decrease


CORRECTING OUT-OF-ORDER PACKETS

1234

1234

• Packets are tagged as they leave the Silver Peak

• Out-of-Order packets are reordered at the receiving side

• Receiving client unaware that out-of-order packets have occurred

• No window size decrease

WHAT DOES IT REALLY MEAN?

LAYER 4-7

LAYER 3• Set & forget - Optimize ANY & ALL traffic• Fix network health issues, accelerates & deduplicates• Optimization is 100% independent of the application or version

• Only optimize specific set applications

• Coordinate software upgrades with WANOP appliance version to avoid breaking applications and optimization

• Unsupported applications can break

REPLICATION ACCELERATION


DATA REPLICATION SHORTFALLS

• Are you consistently meeting your RPO?

• Are you having capacity problems?

• Is all of your data protected?

• Would you like to increase the distance between sites?

FOUR QUESTIONS…


DEFINITIONS

• Recovery Point Objective (RPO)o How much data can you afford to lose?

• Recovery Time Objective (RTO)o How much time before you are up and running again?

UNDERSTANDING RPO AND RTO

REMOTE REPLICATION CHALLENGES

Latency Quality Capacity

Latency (distance) decreases the amount of data that can be sent

across the network

Network errors such as packet loss and out-of-order packets slow

replication throughput

Insufficient network size (capacity) limits the amount of data that can

be replicated over distance


HOW IT WORKS:

DEPLOYING REPLICATION ACCELERATOR

Step 1: Install Silver Peak software on server (15 mins )

Step 2: Point Storage Replication to Silver Peak (5 mins)Step 3: Start optimizing
