    Abstract: A method for managing data, the method includes: providing a write-back cache unit coupled to at least one storage unit; receiving a request to write a new data version to a certain cache data allocation unit; determining, in response to a data storage policy, whether to overwrite a cached data version being cached in the certain cache data allocation unit or to perform a destage of the cached data version to a first storage unit before writing the new data version to the certain cache allocation unit; receiving a request to read a data version that corresponds to a certain point in time and scanning a first data structure representative of write operations and a second data structure representative of revert operations to determine a location of the requested data version.

    Abstract: A method for deploying one or more virtual machines on a host computing system is provided. The method comprises receiving mapping information from a data storage system. The mapping information associates a first data chunk stored in the data storage system with a unique identifier to support deployment of a first virtual machine on a host computing system. Once the mapping information is received, the mapping information is utilized to determine whether any copies of the first data chunk have already been loaded into a memory of the host computing system in association with deployment of the first virtual machine or a second virtual machine on the host computing system. If no copies of the first data chunk have already been loaded into the memory, the first data chunk is retrieved from the data storage system, loaded into the memory, and utilized to deploy the first virtual machine on the host computing system.

    Abstract translation: 提供了在主计算系统上部署一个或多个虚拟机的方法。 该方法包括从数据存储系统接收映射信息。 映射信息将存储在数据存储系统中的第一数据块与唯一标识符相关联，以支持在主计算系统上部署第一虚拟机。 一旦接收到映射信息，就使用映射信息来确定第一数据块的任何副本是否已经被加载到主计算系统的存储器中，与第一虚拟机或第二虚拟机的部署相关联 主机计算系统。 如果没有第一数据块的副本已经被加载到存储器中，则从数据存储系统检索第一数据块，将其加载到存储器中，并用于在主机计算系统上部署第一虚拟机。

    Abstract: Systems and methods for optimizing operation of a physical device in a virtualized computing environment are provided. The method comprises monitoring instructions issued by an application running on a virtual machine's (VM) operating system, wherein the VM is hosted by a hypervisor providing access to a physical device connected to a virtualized computing environment; wherein a device driver supported by the operating system issues one or more instructions to an emulated device supported by the hypervisor to control the physical device according to the issued instructions, wherein the emulated device's registers are implemented in memory of the hypervisor and the instructions issued by the device driver are stored in said registers, wherein the hypervisor handles the instructions, in response to learning that the instructions are stored in said registers.
