LSI Corp has just announced a number of products in its Nytro line of PCIe-based storage cards. The LSI Nytro WarpDrive is a second-generation SSD card available in capacities of 200Gbytes to 3.2Tbytes using a memory-stacking architecture to load the card with MLC or SLC NAND Flash devices. The Nytro WarpDrive employs the company’s SandForce Flash storage processors and SAS controllers. According to the press release, one LSI Nytro WarpDrive delivers the I/O performance of hundreds of HDDs while consuming far less power and requiring far less space in a rack server. Cooling requirements are also reduced, of course.
The LSI Nytro MegaRAID Application Accelerator Cards are HDD RAID controllers with integral NAND Flash caching. These cards automatically shuttle data between the on-board Flash and the HDDs to extract significantly more performance from RAID arrays.
