盘阵列设备、盘控制设备、固态驱动器、盘控制方法和记录介质
摘要：
本发明提供盘阵列设备、盘控制设备、固态驱动器、盘控制方法和记录介质。提供一种盘阵列设备，其使得能够区分SSD中LBA的UNMAPPED状态和数据的异常。盘阵列设备包括：固态驱动器，提供状态信息，该状态信息指示构成要被删除的单元的物理区域是否分配给逻辑块地址；以及控制装置，在从所述固态驱动器接收到数据和尾部的值全为零的零数据之后，根据所提供的状态信息发射数据到主机装置。
摘要（英）：

A disk array device is provided that enables distinction between an UNMAPPED state of LBA in a SSD and abnormality of data. The disk array device includes a solid state drive that provides status information indicating whether a physical region constituting a unit to be deleted is allocated to a logical block addressing, and control means which, upon receipt of zero data in which values of data and a trailer are all zero from the solid state drive, transmits the data to a host apparatus in accordance with the status information provided.
