Described herein is technology for managing cloud storage. In particular, systems, devices and methods for managing cloud storage are described. In some embodiments, management of cloud storage may result in the designation of storage allocated to a first storage pool as obsolete, and the reallocation and/or reclamation of such storage to a second storage pool and/or a general cloud storage pool. Management may occur in accordance with one or more policies.

Technology for managing cloud storage

The invention discloses a method for measuring BMC integrity on the basis of a TPCM and belongs to the field of system safety management. Integrity measurement can be carried out sequentially on a starting program, a kernel program and an application program of a BMC by calling an SM3 algorithm module of the TPCM, whether programs of the BMC is complete or not is judged, and if yes, a prompt indicating that a platform is trusted is sent to a user; otherwise, the user is prompted that the platform is not trusted, exception handling measures are taken by the user, and a measurement result is stored; integrity measurement is carried out on starting running program of the BMC through the TPCM, it is guaranteed that the program is complete and no malicious codes are embedded, and a trusted execution environment is built for the system platform.

The invention provides a CPLD-based system state detecting method, a CPLD and a server mainboard. According to the method, each signal line which can reflect the abnormal state of a system is connected with the complex programmable logic device (CPLD), and a prompt message corresponding to the abnormal state of a signal output by each signal line is set. The method comprises the steps that the CPLD acquires the signals output by the signal lines, the CPLD detects the state of each signal and acquiring the prompt message corresponding to a detected abnormal state, and the CPLD controls a display module to conduct displaying according to the acquired prompt message. By the adoption of the scheme, a user can learn about the abnormal state of the system quickly and determines the state of the system according to the abnormal state, and then accuracy is improved.

The invention discloses a method for the optimal distribution of cloud storage resources, belonging to the cloud storage resource management field. According to the method, an application program needing storage resources, a clod resource proxy, cloud middleware, a storage resource pool and a cloud system server are sequentially connected in structure; when the application program requests resources from the cloud system server; the cloud system server distributes the cloud storage resources according to the request for the resources and the supply of the resources; when the supply of the resources is greater than the request for the resources, the cloud system server responds to the request of the application program according to priority; when the supply of the resources is equal to the request for the resources, the resources are distributed according to Pareto optimal theory. Compared with the prior art, the method for optimal distribution of cloud storage resources provided by the invention has the advantages of improving the storage resource utilization rate, simplifying the storage resource management and reducing the storage cost.
