Problems solved by technology
[0004] Although the Exadata all-in-one machine has built superior storage performance through the open X86 platform, such storage can only be applied to the Oracle database itself under the existing architecture, and Oracle's ASM performs data management. For the database, ASM can See only GRIDDISK
Therefore, even if the storage space and storage performance of the Exadata all-in-one machine are very surplus for the existing business, for example, when the remaining space is 8TB and the IOPS is less than 50% of the overall performance of the system, other business applications cannot take advantage of the excess Exadata data space, resulting in a waste of space

Embodiment Construction
[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0039] like figure 2 As shown, the traditional data access mode of Exadata is: the data of all storage nodes is controlled by the ASM tool 3 of the application host, and the reading and writing of data is managed by ASM as a whole. In this way, although the Exadata all-in-one storage node has very high performance, it must be locked into Oracle's business. The storage of the Exadata all-in-one machine can only be applied to the Oracle database itself under the existing architecture, and the data is managed by Oracle's ASM. For the database, ASM can only see GRIDDISK. The data of al...

The invention relates to a virtualization method for an Exadata storage node. The method can realize full use of Exadata storage space, and the method comprises the following steps: according to usage requirements, reserving part of a disk on the Exadata storage node, and according to a management style of Exadata, handing the reserved disk over to an Exadata Oracle database to use; through a data exchange device, handing the residual disk over to a storage space virtual device to manage; judging whether the Exadata needs more space by the storage space virtual device, if so, releasing the occupied residual disk, and otherwise, continuing to judge until the Exadata needs more space. Compared with the prior art, the virtualization method for the Exadata storage node has the advantages of taking full use of the storage space, being flexible to use, giving full play to technological superiority of a database all-in-one machine, and so on.
Description
technical field [0001] The invention relates to storage technology, in particular to a virtualization method for Exadata storage nodes. Background technique [0002] With the progress and development of database technology, many companies have launched all-in-one products. The outstanding feature of these products is the combination of software and hardware to provide good database performance. A large part of the core ideas of each technology is to solve the bottleneck of storage performance. Take the Exadata database all-in-one machine launched by Oracle as an example, such as figure 1 As shown, it includes computing-intensive processing database service pool 1 and data-intensive processing intelligent storage pool 2, and high-speed interconnected data exchange is realized through InfiniBand between the two. This technology is based on X86 architecture Pcserver, X86 storage, high-speed Flash, Integrated database technology based on high-speed infiniband technology. [0...
