    Abstract: Techniques for utilizing flash storage as an extension of hard disk (HDD) based storage are provided. In one embodiment, a computer system can store a first subset of blocks of a logical file in a first physical file residing on a flash storage tier, and a second subset of blocks of the logical file in a second physical file residing on an HDD storage tier. The computer system can then receive an I/O request directed to one or more blocks of the logical file and process the I/O request by accessing the flash storage tier or the HDD storage tier, the accessing being based on whether the one or more blocks are part of the first subset of blocks stored in the first physical file.

    Abstract: Techniques for using a host-side cache to accelerate virtual machine (VM) I/O are provided. In one embodiment, the hypervisor of a host system can intercept an I/O request from a VM running on the host system, where the I/O request is directed to a virtual disk residing on a shared storage device. The hypervisor can then process the I/O request by accessing a host-side cache that resides one or more cache devices distinct from the shared storage device, where the accessing of the host-side cache is transparent to the VM.

    Abstract translation: 提供了使用主机侧缓存来加速虚拟机(VM)I / O的技术。 在一个实施例中,主机系统的管理程序可以拦截来自在主机系统上运行的VM的I / O请求,其中I / O请求被定向到驻留在共享存储设备上的虚拟磁盘。 然后,管理程序可以通过访问驻留一个或多个与共享存储设备不同的高速缓存设备的主机侧缓存来处理I / O请求,其中主机侧缓存的访问对VM是透明的。
