Problems solved by technology

[0002] In smart devices such as servers, multiple hard disks are usually installed, especially in order to improve the reading speed, multiple solid-state hard disks (such as NVMe SSD) are installed, and the hard disk can be accessed and managed in various ways during use. For example, using a conversion card (NVMe Switch), a signal strengthening card (Retimer card) or a field programmable gate array (FPGA), but the above-mentioned methods cannot make smart devices such as servers correctly identify the logical identification of hard disk devices such as solid-state drives (such as PCIE interface identification) and physical identification (such as slot identification), which makes it impossible for smart devices such as servers to accurately locate hard disk devices such as solid-state drives and effectively manage the hard disk

Embodiment 1

[0036] With the release of Intel's new generation server architecture, all server manufacturers have designed U.2 interface type solid-state disk NVMe SSD support in the new server architecture. As a new high-performance solid-state hard drive, NVMe SSD greatly improves the reading and writing speed of the storage medium, and at the same time shortens the access time between the CPU 4 and the storage medium. For the U.2 solid-state hard drive, it brings convenience in use when it provides hot swap.

[0037] combine figure 2 and image 3 , there are three types of NVMe SSD solutions that support U.2 interface types: NVMe Switch, retimer card, and onboard FPGA. Although the above solutions are more flexible in use, they also bring some other problems, such as The operating system cannot obtain the BayID number corresponding to the NVMe SSD on the front panel of the solid-state disk, so that the hard disk 1 cannot be accurately located during use. However, a method for identif...

Embodiment 2

[0045] The embodiment of the present invention also provides a device for identifying the identification of the hard disk 1, which is applied in smart devices, such as figure 2 with image 3 As shown, the device includes BIOS, firmware (not shown in the figure) and management module, wherein:

[0046] The hard disk 1, especially the solid state disk, is allocated a reserved space, and the BIOS is configured to store the identifier of the hard disk 1 in the reserved space. This reserved space can be independent from other hard disk 1 storage spaces, and the user cannot store data in this reserved space when using the hard disk 1 to store data; Divided space (such as smartlog), the reserved space can store characteristic data such as the name, capacity and temperature of the hard disk 1 for reading and use by smart devices, and the identification can determine the valid data of the corresponding hard disk 1.

[0047] The firmware (not shown in the figure) is set on the hard d...

Abstract

The invention discloses a method and device for recognizing an identifier of a hard disk. The method is applied in intelligent equipment and comprises the steps that reserved space is distributed in the hard disk, and the identifier distributed to the hard disk is stored in the reserved space; and the identifier is mapped to a system management bus of the hard disk, and the identifier is recognized in the system management bus. The method is characterized in that, during management of at least one hard disk especially a solid hard disk, PCIe slot ID (namely a logistic identifier) distributed by intelligent equipment for each hard disk could be recognized accurately and rapidly; BayID (namely an actual physical identifier) of each hard disk on a panel of the intelligent equipment could be recognized rapidly; and PCIe slot ID and BayID could form one-to-one correspondence, so the hardware equipment could be positioned accurately, and thus the hard disk can be managed effectively.
