“After testing with Load DynamiX, we found 30 bugs in 30 days — bugs detected after our other testing tools found nothing. Getting a $1M ROI in one month is pretty cool.”

Packet blasters & replay engines don’t cut it
To support the rapid evolution of the data center, network equipment vendors have been aggressively developing new layers 4-7 technologies (L4-L7). These content aware products accelerate, optimize, monitor and secure modern data center applications.
A key area of data center traffic growth is networked storage traffic, with Gartner estimating that 80% of data center traffic is now flowing East-West from server to server. A growing number and variety of network devices now operate in storage contexts. The ability to inspect, analyze, and transform storage traffic (compression, caching, encryption, etc.) is becoming increasingly important and prevalent among data center networking devices.
“Load DynamiX improved our testing coverage and eliminated the need to buy additional servers. We saved significant dollars using your product.”

To properly test such capabilities requires sophisticated emulation of storage workloads based upon deep emulation of storage protocols, and sophisticated content verification capabilities. Traditionally, Network Equipment Manufacturers have relied on a mix of “packet blasters” to test L2-L3 devices and “replay engines” to test L4-L7 devices. These approaches fail in the storage context. “Packet blasters” lack the flexibility and depth to perform anything more than cursory emulations of storage protocols, and yield rather unrealistic workloads. “Replay engines” are simply too brittle as they can only emulate limited protocol-based interaction with the device under test.
A new testing solution is required.
