Abstract: A peripheral component interconnect express (PCIe) solid state drive (SSD) accelerator, having a PCIe card and separate a flash daughter-card, is provided. By including flash memory devices on a separate daughter-card, the flash memory devices are thermally decoupled from the hotter devices on the main PCIe providing additional thermal operating margins for the entire design. Furthermore, as flash memory devices are the most likely part of the subsystem to wear out over time due, including flash memory devices on a separate daughter-card allows the flash memory devices to become a field replaceable unit that can be easily replaced. EEPROMs may be included on the flash daughter-card to record the current wear state of the NAND flash devices. Knowing the wear history of the flash memory device allows the seller to replace the flash daughter-card of a customer with a daughter-card having a similar wear state.

Abstract: One feature pertains to cooling of a high density array of non-volatile memory mass storage devices within a computer enclosure. A coolant is moved through the enclosure through two separate air paths, each serving approximately half of the mass storage devices.
