20140059292 | TRANSPARENT HOST-SIDE CACHING OF VIRTUAL DISKS LOCATED ON SHARED STORAGE - 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. | 02-27-2014 |
20140115256 | SYSTEM AND METHOD FOR EXCLUSIVE READ CACHING IN A VIRTUALIZED COMPUTING ENVIRONMENT - A technique for efficient cache management demotes a unit of data from a higher cache level to a lower cache level in a cache hierarchy when the higher level cache evicts the unit of data. In a virtualization computing environment, eviction of the unit of data may be inferred by observing privileged memory and disk operations performed by a guest operating system and trapped by virtualization software for execution. When the unit of data is inferred to be evicted, the unit of data is demoted by transferring the unit of data into the lower cache level. This technique enables exclusive caching without direct involvement or modification of the guest operating system. In alternative embodiments, a pseudo-driver installed within the guest operating system explicitly tracks memory operations and transmits page eviction information to the lower level cache, which is able to cache evicted pages while maintaining cache exclusivity. | 04-24-2014 |

20140325141 | TRIM SUPPORT FOR A SOLID-STATE DRIVE IN A VIRTUALIZED ENVIRONMENT - A computer system that employs a solid-state memory device as a physical storage resource includes a hypervisor that is capable of supporting TRIM commands issued by virtual machines running in the computer system. When a virtual machine issues a TRIM command to its corresponding virtual storage device to invalidate data stored therein, the TRIM command is received at an interface layer in the hypervisor that translates the TRIM command to a SCSI command known as UMMAP. A SCSI virtualization layer converts the UNMAP command to a file system command to delete portions of the virtual storage device that is maintained as a file in the hypervisor's file system. Upon receiving the delete commands, the hypervisor's file system driver generates a TRIM command to invalidate the data stored in the solid-state memory device at locations corresponding to the portions of the file that are to be deleted. | 10-30-2014 |
20140344504 | HYPERVISOR-BASED FLASH CACHE SPACE MANAGEMENT IN A MULTI-VM ENVIRONMENT - Techniques for managing space in a flash storage-based cache are provided.
