LSI Nytro WarpDrive Internals
Pulling the WarpDrive apart, we can observe that each large metal heatsink holds two SSD modules. This design focuses on providing efficient thermal dissipation in high-heat server environments. With the temperature thresholds rising in many datacenters to ease power consumption for cooling, heat mitigation is important to extend the longevity of the NAND and controllers.
Each module connects to the device via ports connected to the PCB with a ribbon cable.
Upon closer inspection, we note that each metal plate has large pink thermal pads that sandwich each SSD module on both sides. This furthers the efficient heat transfer from the components to the heatsink.
Both sides of each PCB are in view in this picture. The SandForce SF-2582 FSP (Flash Storage Processor) is located at the bottom of the PCB on the right. The obscured markings are due to the oily residue from the thermal pads.
The Toshiba Toggle NAND packages of eMLC are each 32GB in capacity, totaling 256GB of raw flash per SSD. After RAISE and the standard overprovisioning there is 200GB of user addressable NAND per SSD, for an aggregate of 800GB for the entire WarpDrive.
