Previously, LSI offered caching software, called CacheCade, on the RAID card. It's new Nytro XD ports the software directly onto the server to be used by the operating system.
"By doing that, the caching capability can be extended to external storage without actually touching the array," Jamon said. "It's caching not tiering, so it keeps a copy of the data on the [storage] array."
The third product, the Nytro MegaRAID, combines less than 100GB of NAND flash with a RAID controller in a sealed unit. It is also a caching device, but it is designed to be simple to implement and is aimed at lower-end applications that don't require massive amounts of high-performance NAND flash.
"It's all pre-configured, there's no software on the host and so it makes it easy for an administrator to set up," Jamon said.
The Nytro MegaRAID card can increase the number of transactions per second on a SQL server by as much as 10 times over servers with hard drives only and improve response times on an Oracle database by as much as 30 times, according to LSI.
LSI's Nytro PCIe cards are being tested with with system manufacturers and are expected to be generally available beginning in the second quarter of 2012.
Pricing for Nytro WarpDrive cards starts at $6,600; pricing for Nytro XD solutions start at $9,400; and pricing for Nytro MegaRAID cards starts at $1,699.
