摘要： A storage system and method are provided including physical storage devices controlled by storage control devices constituting a storage control layer operatively coupled to the physical storage devices and hosts. The storage control layer includes: a first virtual layer interfacing with the hosts, operable to represent a logical address space characterized by logical block addresses, characterized by an Internal Virtual Address Space (IVAS) and operable, responsive to I/O requests addressed to logical block addresses, to provide protocol-dependent translation of said logical block addresses into IVAS addresses; and a second virtual layer interfacing with the physical storage space, and operable to represent available physical space to said hosts and characterized by a Physical Virtual Address Space (PVAS). Each address in PVAS having a corresponding address in IVAS. The second virtual layer is operable to translate PVAS addresses corresponding to IVAS addresses into addresses in physical address space in a protocol-independent manner.

摘要： In order to avoid loss of data, computer systems are often connected to a UPS which provides power backup in case of an emergency shutdown resulting from a power failure. However, as UPS units are costly, they take up a lot of physical space and can provide power for a limited period of time, it would be advantageous to improve the efficiency of UPS devices and enable to utilize as much as possible of the UPS power in order to save data to a permanent storage before shutdown. There is provided a method and system for controlling the frequency of one or more processors in computer systems, responsive to an indication of a power failure, and thereby reduce its power consumption, so as to provide more power for writing write-pending data to a non-volatile data storage.

The storage arrangement comprises a first storage system and one or more second storage systems operatively coupled to the first storage system. First control layer is operable to handle a first logical address space comprising a first logical group characterized by a plurality of logical block addresses; first control layer comprises a first mapping module handling a first mapping structure associated with first logical group. Each second control layer comprises, respectively, a second mapping module handling a second mapping structure associated with first logical group. The first mapping structure is configured to provide mapping between logical addresses related to first logical group and corresponding addresses related to first physical address spaces, and/or to point to respective second mapping structure configured to provide mapping between these logical addresses and corresponding addresses related to respective second physical address spaces.
