These flexible flash design options with the Nytro MegaRAID card give customers multiple 
possibilities for configuring their own ‘optimal’ server solution.

Serving data requests from flash can significantly reduce application latency, leading to 
improved user response times and quality-of-service.  The graph below compares the 
performance of a SQL Server® database driven by an online transaction processing (OLTP) 
workload in a hardware configuration with only HDDs against a Nytro MegaRAID  
card-supported configuration.  In this test case performed by LSI in its labs, the Nytro MegaRAID 
card’s intelligent caching and integrated flash storage yielded an 80x faster response

Applications that benefit from caching can also benefit from reduced rebuild time for 
degraded RAID arrays, even when using high-capacity HDDs.  With the Nytro MegaRAID card 
servicing IO from the onboard flash, the backend HDDs are less burdened and can dedicate 
more resources to the rebuild operation.  

The Nytro MegaRAID card utilizes the strength of the LSI technology portfolio to deliver an 
enterprise-quality solution.  The LSI MegaRAID stack offers enterprise data protection while LSI 
SandForce® flash processors help ensure enterprise-grade flash performance and endurance.  
Nytro MegaRAID card’s broad range of supported operating systems - including in-box drivers 
- make it possible to replace the standard RAID card or HBA that would already be needed in 
many server designs with an accelerated flash solution.
