Use Case
Replication Acceleration

Stack
SQL Server

Qualcomm is a world leader in next generation wireless technologies with over 11,000 patents and $10 billion in revenue.

High performance WAN communication is essential to Qualcomm’s international operations across all departments.

In situations where security, reliability, and scalability are paramount, Nitrosphere’s air gapped software acceleration solution is paramount.

Challenge
SQL Server Replication Backlog

In situations where Qualcomm utilizes SQL Server to replicate data across distance using pull transactional replication. Before deploying NitroAccelerator, the replication over the WAN simply was not able to keep up with demand. This issue created bottlenecks across multiple departments and essential business processes.

Solution
Network Acceleration as Software

NitroAccelerator was installed to Qualcomm’s SQL Servers within the network without user interruption.

Initial tests contained 1.2 million commands replicated between San Diego and China. With NitroAccelerator enabled the commands per second shot up from 166 to 9000 per second and the time to replicate fell to just 5 minutes from 110 minutes.

Result
LAN Levels of Performance Over the WAN

Qualcomm now has NitroAccelerator in place between sites allowing them to achieve near real-time replication that seamlessly keeps pace with increases in oversea production. Currently they are pushing over a terabyte of data per month between sites.

“We are doing a pull transactional replication from our SQL Server in China to San Diego. I did two tests comprised of about 1.2 millions commands each. I was very impressed with the results (average numbers below).”

“The compression rate according to SQL NitroAccelerator was 85% … The Distribution Agent actually had to wait for the Log Reader Agent.”
