SYSTEM AND METHOD FOR OPTIMIZED DISK IO RAM CACHING FOR A VDI ENVIRONMENT

摘要

A system and method provides optimized caching to RAM of disk input/output operations in a virtual environment, such as a virtual desktop infrastructure environment (VDI), thereby reducing the I/O operations per second (IOPS). Generally, existing technologies allocate a fixed amount of RAM for caching based on static criteria and do not consider the actual RAM utilization at a particular point in time. The system and method provides a mechanism for lowering the costs associated with TOPS by utilizing relevant assessment techniques to determine actual RAM usage. The system and method provides an information handling system to dynamically allocate cache so as to optimize the allocation of RAM to cache for use by I/O operations in any virtual environment, for example, a VDI environment. By providing a dynamic allocation the disk requirements for implementing a VDI environment may be reduced.

1. A method of optimizing caching in a virtual desktop environment comprising:
configuring a cache for use by one or more virtual machines, wherein the cache is allocated from a memory; monitoring utilization of the memory based, at least in part, on one or more relevant assessment techniques; defining an upper threshold; defining a lower threshold, wherein the upper threshold and the lower threshold define a usage range for the memory; determining if the utilization of the memory is within the usage range; increasing the memory allocation to the cache when the utilization of the memory is less than the lower threshold based, at least in part, on the one or more relevant assessment techniques; and decreasing the memory allocation to the cache when the utilization of the memory is greater than the upper threshold based, at least in part, on the one or more relevant assessment techniques.
