A method, apparatus and program storage device for dynamically resizing mirrored virtual disks in a RAID storage system is disclosed. Mirrored virtual disks are expanded by creating the amount of storage necessary by providing RAIDs on each subsystem that is associated with each of the components of the mirror set, attaching the RAIDs to the specific Virtual Disks for each of the mirror devices, and specifying the Virtual Disk size and mapping this directly to all components via the source Vdisk of the mirror set. To decrease the size of mirrored virtual disks the process is reversed, with the inclusion of the optional requirement that some raids will need to be truncated to provide exact shrink values without sacrificing storage space.

The invention discloses a rapid horizontal extending method for databases, which belongs to the field of data migration and storage. The method comprises the following steps: a monitoring and control system carries out monitoring on the disk storage space of the existing database, and when the disk size reaches a preset storage capacity threshold, the monitoring and control system triggers a hardware storage increasing action so as to make a hardware environment preparation for data migration; and a routing protocol carries out a modular computation on the instance number N of the current database according to a major key ID to be inserted currently, and routes the line number of data to be inserted into a specified database, and when the number of inserted lines exceeds a preset storage number threshold, the routing protocol triggers a database segmentation action so as to migrate specified data into a new database, thereby completing the rapid horizontal extending of the database. The method disclosed by the invention can be applied to disk databases or memory databases, and the method is easy to use and simple, and avoids the problem that hotspots are distributed nonuniformly caused by traditional horizontal extending of databases; in addition, as the scale of migration of data segmented each time is small, the extending speed is improved. In conclusion, the overall architecture meets the requirements on high availability, high reliability, high speed, high efficiency and the like.

The invention discloses a method for on-line extension of the disk size of a virtual machine and a virtual system console. The method comprises the steps that the console obtains information for expanding the disk size of the virtual machine, the information for expanding the disk size comprises an identification label number of the virtual machine and the size of a disk expansion space applied by a virtual machine disk, a disk expansion space is generated in a storage disk according to the size of the disk expansion space applied by the virtual machine disk and on the basis of a preset distribution rule, and the virtual machine needing expansion of the disk size is found according to the analyzed identification label number of the virtual machine; configuration information of the virtual machine is modified and stored according to the property of the disk expansion space, and the disk expansion space of the storage disk is distributed to the disk of the virtual machine. According to the method, on-line extension of the disk size of the virtual machine can be conducted without interrupting an operation system of the virtual machine, and therefore continuity of service of the virtual machine is guaranteed.

Systems and methods are provided that may be used to automatically create RAID configuration with heterogeneous Physical Disk (PD) set up using Virtual Disk (VD) RAID Level and size, for example, to allow replication of a given RAID configuration across multiple different RAID platform systems regardless of the underlying storage disk sizes and/or storage disk types.

A size planning method for a storage device, and read and access correcting methods thereof are described. When a computer device is booted, a size of a physical storage device is managed. The management method includes the following steps. A physical storage device connected to a computer device is searched. When a size of the physical storage device is larger than a maximum disk size, a current disk having a specified size is partitioned from the physical storage device. Various parameters of a logical fixed disk parameter table (FDPT) extension table of the current disk are set. A residual size of the physical storage device is partitioned into several disks having the specified size, and the corresponding logical FDPT extension tables are set until the residual size is smaller than the maximum disk size.

The invention discloses a ZnSe semi-cylindrical mirror development process. The invention provides the ZnSe semi-cylindrical mirror development process in order to overcome the defects existing in theprior art. The ZnSe semi-cylindrical mirror development process includes the following steps that S1, according to the product size (R12.7*12.7*25.4), a corresponding face mirror base material is selected for use, and the size is 28*27*14; S2, disk forming for machining the base material is performed, the whole disk size consistency can be guaranteed well due to ring grinding machining, and six surfaces are machined; S3, ring polishing of the 27*25.4 face is performed till the size is 27*25.4*13.5(0/-0.005); S4, two semi-finished products where ring polishing is completed are taken, the two polished faces (27*25.4) are glued with photosensitive glue, the plane finish degree is guaranteed well, and the size of the semi-finished products after being glued is 27*27*25.4, edge grinding is performed, and edge grinding is performed till the outer diameter D25.6(0/-0.02) size is achieved; and S7, the two products are dismantled, the plane photosensitive glue is removed, disk feeding is performed, low polishing machining of a product cylindrical face is performed, and the client requirement is met; and the product consumption size is consistent before polishing, and the polishing machining size consumption is about 0.02; and S8, disk discharging is performed, cleaning is performed, edge chamfering is performed, and a product is completed. The ZnSe semi-cylindrical mirror development process utilizes a conventional cuboid base material, and cost is effectively saved.

The invention provides a virtual machine starting apparatus and method, and a host. The apparatus and the method are applied to each host in communication connection with a storage device; at least one virtual machine is deployed in each host; and virtual disk files used for starting the virtual machines are stored in the storage device. The apparatus comprises a virtual machine starting module used for obtaining a virtual disk size value recorded in header information of a target virtual disk file when a starting instruction for starting any virtual machine through the target virtual disk file is executed, and starting the virtual machine through the target virtual disk file when the virtual disk size value is greater than a preset threshold value, and a header information modification module used for modifying the virtual disk size value recorded in the header information of the target virtual disk file to a preset size value when the virtual machine is started successfully through the target virtual disk file, thereby preventing other virtual machines from being started through the target virtual disk file.

The present invention provides disk coercion by generating coercion percentages or values that can be used to coerce various disks according to each disk's particular labeled size or capacity. In one embodiment, a disk size is received and a base coercion scaling factor is provided such that the received disk size is coerced according to the base coercion scaling factor if the labeled disk capacity is below a disk size threshold. The coercion scaling factor increases for labeled disk capacity above the disk threshold. If the labeled disk capacity is above the disk size threshold, then a coercion scaling factor is provided according to the rate of increase of coercion scaling factors and the labeled disk capacity.
