Product Brief
Powered by Virtual Pipeline™ Technology
The Nytro MegaRAID card offers LSI MegaRAID data protection and flexible onboard flash
technology that can be used in a variety of ways to help improve performance and server
storage density. Server deployments currently using a standard RAID card or Host Bus Adapter
(HBA) have the potential for higher performance simply by switching to the versatile and
innovative Nytro MegaRAID card.

Simple-to-Deploy Flash Technology
Flash-based storage offers low latency and high IOPS, with solid state drives (SSDs) as a typical
flash solution. To qualify SSD solutions customers must balance the SSDs cost, capacity,
performance, and enterprise data integrity versus their traditional hard disk drive (HDD)
infrastructure. Different applications may require different capacities of flash to achieve
targeted performance, expanding the number of server configurations to manage. The
addition of SSDs may also take up drive bays typically dedicated to HDDs, reducing the total
available server capacity. LSI helps remove these obstacles by placing enterprise-grade
flash capacity on the Nytro MegaRAID card, providing customers an easier-to-qualify and
performance-optimized flash solution. In servers using a traditional RAID card or HBA, simply
replacing them with a Nytro MegaRAID card can deliver flash-based performance and design
flexibility without changing other components within the server.

Flexible Flash to Fit Your Needs
The Nytro MegaRAID card is designed with individual flash modules – essentially two
enterprise-quality SSDs – onboard. These flash modules can be configured in a RAID array
to support latency-sensitive data storage – used for the boot volume, the ‘golden image’ in
a virtual desktop infrastructure (VDI) application, storing tempdb in SQL Server or indexes/
data objects from an Oracle or MySQL database, for example – and will still support a caching
volume as well, dynamically identifying ‘application hot data’ to be stored and serviced from
the flash for improved performance and reduced latency.

the flash for improved performance and reduced latency.
Total server storage density can be increased simply by storing the boot volume in the
onboard flash. Two HDDs previously dedicated for boot support can now be used for
application data, increasing total server capacity without any other hardware changes. Storing
tempdb in a SQL Server database application or the golden image in a VDI application can
improve performance simply by servicing these operations using the Nytro MegaRAID card’s
onboard flash.
