QoS
Prioritize
critical traffic
TCP Flow Control
TCP waits for a ACK
after 64 Kbytes are sent
on the wire
TCP does not like to
compete for bandwidth
Multiple TCP sessions
collide with each other
causing back off and
retransmit behavior

Compression and Deduplication
Compression and
Deduplication work by
analyzing the data and
searching for
redundancies.
• Without Compression:
AAAAAAAAAABCDAAAAA
AAAAA (23 digits)
• With Compression:
Ax10BCDAx10 (11 digits)

Protocol Acceleration
Accelerates various
protocols that WANs use
to communicate. Thus
minimizing the number
of back-and-forth trips
taken.

Application specific optimizations
Protocol Acceleration
First generation CIFS wouldn’t send the next packet until the preceding ACK was
received – not true any longer
MAPI is still pretty chatty
HDX benefits from de-duplication and QoS

NetApp’s SnapMirror application includes compression functionality
• Enabling compression affects file server performance
CloudBridge accelerates better:
• Better TCP window size adjustment
• Congestion measurement and control
• De-duplicates across storage volumes
CloudBridge’s acceleration benefits are complimentary to NetApp’s

CloudBridge Connector
Feature to build a cloud-extended data center
Create bridges to connect one or more virtual private clouds (VPCs) to your
network
No reconfiguration of your data center
Enables to create a seamless connectivity between:
• Your existing data center and applications hosted in the VPC
• Two Clouds
• Data Center to Data Center
- AWS, Azure, SoftLayer, etc
