- Abstract
- In general, the virtual desktop infrastructure builds and manage a virtual machine in a cloud environment to access it remotely in order to use the user's desktop existing OS such as window, linux, mac, etc. Virtual machines for virtual desktops is created as virtual machine images on disk storage. In this case, the usage of high-speed storage (SSD, NVMe, etc.) is increasing due to the limitation of I/O performance, and there are even cases where a virtual machine image is maintained and used in main memory. Operating a virtual machine image on main memory can increase its performance compared to any other disk. However, RAM used as main memory is expensive and disappears after the system is shut down due to its volatile characteristic. Therefore, additional work is required to operate the virtual desktop on the main memory. In this paper, a hybrid in-memory storage is proposed to combine main memory and other disk such as a high-speed SSD to safely operate a virtual desktop on RAM (main memory) from the volatile characteristic. Also, the proposed storage shows 6 time faster for writing and 42 time faster for reading operation comparing with general disk.
