(EN) The disclosure relates to a write-back storage cache based on a fast persistent memory. A storage device uses non-volatile memory devices for caching. The storage device operates in a mode referred toherein as write-back mode. In write-back mode, a storage device responds to a request to write data by persistently writing the data to a cache in a non-volatile memory device and acknowledges to therequestor that the data is written persistently in the storage device. The acknowledgement is sent without necessarily having written the data that was requested to be written to primary storage. Instead, the data is written to primary storage later.
(ZH) 本公开涉及基于快速持久性存储器的回写储存器高速缓存。储存设备使用非易失性存储器设备用于高速缓存。储存设备以这里称为回写模式的模式操作。在回写模式下，储存设备响应于写入数据的请求，永久性地将数据写入到非易失性存储器设备中的高速缓存中，并且向请求者确认数据被永久性地写入到储存设备中。确认是在不一定将请求写入的数据写入到主储存器的情况下发送的。相反，数据稍后被写入到主储存器。
