Within short a few years, store Virtual Have already proved it has been worth and pass by the old road from up-market solution of costing an arm and a leg to goods of the moderate price in the big enterprise. As a standard function of the memory array of most middle levels, storing and turning a medium and small organization fictitiously solves extensive memory and manages the difficult problem. At the same time, the special solution of the first-class manufacturer has offered the greatest investment repayment for the fact that manage the large-scale enterprises with large-scale memory LAN of the intensive data usability demand.
Store virtual to establish first abstract layer store, in host computer and physics, have concealed the characteristic of storing the apparatus singly. When implementing while storing the LAN in one, it has offered a single management for the fact that all piece grades are stored to click. To be simple, store virtually and store a plurality of varied networks apparatuses to concentrate together, offer one group to store one and is used as host computer fictitiously.
Besides establishing the memory pool composed of physical hard disks of different arrays, store virtually and offer the extensive service in unanimous way. These services begin with basic roll management, including LUN logic unit number Shield, connect in series, roll divide into groups and segment, simplify disposition and automatic roll expand and automatic data move and data protect with disaster recovering the function including the snapshot and making mirror images . In brief, the virtual solution can be used as enforcing and storing the management policy and realizing a central control point of one grade of agreements of higher service.
Perhaps the virtual most important services that realizes are not to produce the confused data to move. To large-scale organization, it is almost the life fact not changed to move the data. Since the end of old apparatus lease and reach the standard grade with the new apparatus, storing virtually can realize that move without cutting off the service to piece one grade of data of another apparatus from an apparatus. Store administrator’s maintenance very apt to carry on the walking example or change the outmoded memory array, will not interfere with application program and user. The production system will keep running.
