Abstract: Determining whether to compress data of a virtual storage unit based at least in part on: an I/O activity value of a virtual storage unit; a compressibility value of the virtual storage unit; and/or a capacity utilization of the storage system or a component thereof. For example, decision logic may be configured based on one or more of such parameters such that virtual storage units with relatively high I/O activities are rarely or never compressed, e.g., to avoid the disproportionately high increases in CPU and bandwidth resource consumption and I/O latency this could create. Decision logic may be configured such that, in general, the likelihood that a virtual storage unit will be compressed increases as: the I/O activity of the virtual storage unit decreases; the system capacity utilization increases; and/or as the compressibility value of the virtual storage unit increases.

Abstract: A system and method of translation bypass includes a hypervisor retrieving a physical bus address range from a host input-output memory management unit. The hypervisor reserves an allowed address range of the physical bus address range, and sends the allowed address range to a guest virtual machine.

The hypervisor stores the access request to the guest bus address in physical memory mapped in the host input-output memory management unit to an address outside of the allowed address range.

The positions of similar repository data are found in a repository of data for each of the data chunks. The input digests of the input data are matched with the repository digests contained in the global digests cache for locating data matches.

The positions of the similar repository data are used to locate and linearly load into the global digests cache, digests and digest block boundaries of the similar repository data.

Abstract: In a hierarchical storage memory (HSM), a file recalled by a specific application is migrated as soon as possible after completion of the application process. Specifically, the effective UID of a specific process is preregistered on an HSM client. After a recall operation is performed on a certain file from the user ID, when there is no access from the UID to the file for a given length of time, the file is migrated. This prevents files premigrated by access from any application other than the specific one from being handled in the same way, resolving a disadvantageous problem caused when these (premigrated) files are not desired to be migrated preferentially.

The method continues by determining whether the data segment is recoverable. The method continues, when recoverable, by salvaging the region by indicating that the region has corruption, updating a directory and replacing the data segment with filler data, and when not recoverable, by not salvaging the region by indicating that the region has been eliminated.

This property is that according to which when all the bits of the bytes of a digital word grouping together n bytes are equal to zero, the check bits associated with these bytes are also all equal to zero.
