Description
Technical Field
The field relates to the field of computers, and more particularly to a method and apparatus for dynamic allocation of hard disk resources.
Background
The hard disk is an indispensable component of a server storage unit, and currently, commonly used hard disks include SAS (serial attached SCSI interface), SATA (serial advanced technology attachment), and NVME (non-volatile memory express) hard disks according to different transmission protocols. The SATA hard disk, also known as a serial hard disk, adopts a serial connection mode, uses an embedded clock signal, has strong error correction capability, can check transmission instructions, improves the reliability of data transmission, and has the advantages of simple structure and hot plug support. SAS is a new SCSI technology, and SAS hard disks also use a serial technology to achieve higher transmission speed, improve internal space by shortening a connection line, and are compatible with SATA hard disks.
With the increasing demands of server application scenes on storage, a limited SAS interface provided on a CPU of a server mainboard is not enough to meet the application demands of high storage of multiple hard disks, and the Expander chip expanded by the SAS transmission interface and the SAS Expander back plate can be operated accordingly. SAS Expander backplanes are typically used with HBA or RAID cards to build an even larger storage system based on SAS technology by forming an advanced switched topology.
When the hard disk device hung under the SAS Expander back plate expansion is used, the bandwidth and the speed of the hard disk device are controlled by an Expander internal controller and Firmware, and the bandwidth and the speed of the hard disk device are usually fixed upper limit values, so that the flexible allocation of resources and the utilization efficiency of a storage unit are greatly reduced. How to reasonably distribute the hard disks for use while expanding the storage resources through the SAS Expander back plate, and improve the operation efficiency of the storage unit becomes an important link for improving the resource utilization rate of the server.
Currently, an Expander Firmware capable of realizing different interface transmission rate allocations is developed by chip manufacturers. In the existing server storage unit design, by manually pre-judging the types and the rates of the hard disks connected to the SAS Expander backplane, operators manually refresh Firmware of the SAS Expander backplane. And after the machine is shut down and restarted, the refreshed Firmware can be used.
The disadvantages of the prior art solutions are mainly: the online upgrade and maintenance of Firmware of the SAS Expander back plate cannot be realized: after the Firmware of the SAS Expander back plate is refreshed, the restarting party must be shut down to take effect, and the running service of the server is interrupted; dynamic bandwidth and resource allocation of the storage device cannot be realized: when the SAS Expander backplane is connected to a plurality of hard disks, if the speed of uplink channels of different hard disks needs to be adjusted, the types of the hard disks need to be manually identified or instructions need to be manually input to measure the read-write speed of the hard disks, and then Firmware is selected for burning, and the read-write state of the mounted hard disks is allocated, so that the waste of human resources is caused.
