Cluster solid state drives

摘要

Described herein are techniques for arranging a plurality of M.2 solid state drive (SSD) modules and flash storage elements into a compact form factor. On a first side of an SSD sled, a plurality of M.2 SSD modules may be communicatively coupled to a port expander. On a second side of the SSD sled, a plurality of flash storage elements (not packaged into M.2 SSD modules) may be present. A plurality of SSD sleds (with the above-described characteristics) may be sized so as to collectively fit into a single hard disk drive (HDD) compatible compartment of a chassis.

1. A storage system, comprising:
a plurality of solid state drive (SSD) sleds, wherein each of the SSD sleds includes:
(i) a plurality of M.2-compliant SSDs, each of the M.2-compliant SSDs comprising a serial advanced technology attachment (SATA) SSD controller and a plurality of NAND flash chips,(ii) a port expander of the SSD sled, each of the M.2-compliant SSDs being communicatively coupled to the port expander of the SSD sled, and(iii) a plurality of flash storage elements, each of the flash storage elements comprising a NAND flash chip,wherein the plurality of SSD sleds is sized so as to collectively fit into a single hard disk drive (HDD) compatible compartment of a chassis,wherein the M.2-compliant SSDs are arranged on a first surface of the SSD sleds and the flash storage elements are arranged on a second surface of the SSD sleds, andwherein the first surface faces a first direction and the second surface faces a second direction opposite to the first direction.
