Server and drive control device

摘要

According to one embodiment, a drive control device includes a monitor, data memory and a controller. The monitor monitors an operating state of a solid-state drive and detects whether the solid-state drive is busy. The data memory is capable of holding temporarily a write target data which should be written to the solid-state drive or a read target data which was read from the solid-state drive and should be transmitted to a requestor. The controller which writes the write target data to the data memory when the controller receives a write request and the monitor detects that the solid-state drive is busy, and which writes the write target data held in the data memory to the solid-state drive after the solid-state drive becomes not busy.

1. A drive control device, comprising:
a monitor which monitors an operating state of a solid-state drive and detects whether the solid-state drive is busy; a data memory which is capable of holding temporarily a write target data which should be written to the solid-state drive or a read target data which was read from the solid-state drive and should be transmitted to a requestor; a controller which writes the write target data to the data memory when the controller receives a write request and the monitor detects that the solid-state drive is busy, and which writes the write target data held in the data memory to the solid-state drive after the solid-state drive becomes not busy, wherein the controller writes the write target data directly to the solid-state drive without performing writing of the write target data to the data memory and reading of the write target data from the data memory when the monitor detects that the solid-state drive is not busy.
