Abstract

Embodiments of the inventive concept include solid state drive (SSD) multi-card adapters that can include multiple solid state drive cards, which can be incorporated into existing enterprise servers without major architectural changes, thereby enabling the server industry ecosystem to easily integrate evolving solid state drive technologies into servers. The SSD multi-card adapters can include an interface section between various solid state drive cards and drive connector types. The interface section can perform protocol translation, packet switching and routing, data encryption, data compression, management information aggregation, virtualization, and other functions.
