Storage head node of blade server

Abstract

The invention discloses a storage head node of a blade server. The storage head node comprises a storage control unit, a magnetic disk storage unit and a hard disk backplate, the storage control unit is used for receiving and storing data information, processing the data information according to computation tasks of other storage heat nodes and performing feedback, the data information is read and written through read-write control instructions of an SAS unit and the hard disk backplate, the SAS unit converts the data information into data information of SAS signals and writes the the data information of the SAS signals in the magnetic disk storage unit, the magnetic disk storage unit writes in or reads the data information of the SAS signals which are subjected to the SAS unit according to a received writ-in control instruction or a received reading control instruction, and the hard disk backplate is used for realizing reading and writing of the data information according to a read-write control instruction from the storage control unit. Reading and writing of the data information are realized through the control instructions of the SAS unit and the storage control unit to complete the computation tasks and feed the completed computation tasks back to the corresponding storage head nodes, and unified management of storing and processing of the data information is realized.

Description

technical field [0001] The invention relates to the field of servers, in particular to a storage head node of a blade server. Background technique [0002] With the explosive growth of network data volume, in the process of data storage and processing, the requirements for the comprehensive capabilities of servers for storing and processing data are also continuously increasing. The current blade server mainly adopts standard external storage to construct the system, which is connected with the external storage through the Fiber Channel (FC) switching module in the system; each external storage is connected with the storage control device by cables. In the continuous development of big data, each external storage is connected by cables, which brings great difficulties to the deployment and implementation of storage expansion of the blade system. At the same time, because the current blade server stores the data information received by the system from the computing nodes and...

Problems solved by technology

In the continuous development of big data, each external storage is connected by cables, which brings great difficulties to the deployment and implementation of storage expansion of the blade system.

At the same time, because the current blade server stores the data information received by the system from the computing nodes and controls the data information, the data processing process is too isolated, and the unified management of data storage and processing cannot be realized.
