Abstract: Techniques for enabling integration between a storage system and a host system that performs write-back caching are provided. In one embodiment, the host system can transmit to the storage system a command indicating that the host system intends to cache, in a write-back cache, writes directed to a range of logical block addresses (LBAs). The host system can further receive from the storage system a response indicating whether the command is accepted or rejected. If the command is accepted, the host system can initiate the caching of writes in the write-back cache.

Abstract translation: 提供了用于实现存储系统和执行回写高速缓存的主机系统之间的集成的技术。 在一个实施例中，主机系统可以向存储系统发送指示主机系统打算在写回高速缓存中缓存针对一定范围的逻辑块地址（LBA）的写入的命令。 主机系统可以进一步从存储系统接收指示该命令是接受还是被拒绝的响应。 如果命令被接受，则主机系统可以启动缓存写入高速缓存中的写入。
