摘要：
A new all-solid-state-drive (all-SSD) storage system, which does not suffer performance degradation due to garbage collection, for high-performance enterprise storage is proposed. The storage system has two new functions, namely, an indication of garbage collection ("GC indication") and a dynamic allocation of a reserved SSD ("DLS allocation"). Cooperation between these two functions can dramatically shorten maximum write and read response times of the system by 87% and 92%, respectively. These reductions were confirmed by an FPGA emulator simulating the system.
