Embodiment 1

[0031] Such as figure 1 As shown, the function of single-controller storage is implemented as follows:

[0032] 1. Single-controller storage uses IET to create an iSCSI Target (iSCSI target), and the iSCSI Initiator (iSCSI initiator) accesses it through the network. It realizes the transmission of SCSI protocol on TCP / IP network, and realizes the transmission of data between networks.

[0033] 2. The IET stored by a single controller uses a self-developed Cache module, which realizes the interface with IET and NVDIMM, improving the performance and reliability of data reading and writing.

[0034] 3. Single-controller storage uses NVDIMM to realize data protection and recovery when the system is powered off. NVDIMM needs to be connected with the Linux system, IET module and Cache module.

[0035] 4. Single-controller storage uses SATA / SAS controllers to connect disk devices.

[0036] Such as figure 2 As shown, the internal interface of the single-controller storage system ...

Abstract

The invention relates to the technical field of storage of single controllers, in particular to a method for implementing single controller storage. iSCSI (Internet Small Computer System Interface) read-write operation is cached and optimized through a Cache module pair implemented by an IET (iSCSI Enterprise Target) module, and data protection and recovery in a system abnormal power failure state are implemented with a NVDIMM (Non-Volatile Dual In-line Memory Module). The implementation method is simple, reliable, low in cost and excellent in performance, and high-performance and high-reliability single controller storage can be implemented.

Description

technical field [0001] The invention relates to the technical field of single-controller storage, in particular to a method for realizing single-controller storage. Background technique [0002] iSCSI is the abbreviation of internet Small Computer System Interface, also known as IP-SAN. The iSCSI technology is a kind of SCSI instruction set developed by IBM researched and developed for hardware devices that can run on the upper layer of the IP protocol. The command set can implement the SCSI protocol running on the IP network, enabling it to perform routing on such as high-speed Gigabit Ethernet. iSCSI technology is a new storage technology, which combines the existing SCSI interface with Ethernet technology, so that the server can exchange data with the storage device using the IP network. [0003] This storage technology realizes the transfer of data between networks by transmitting SCSI commands and data on the IP network. Due to its excellent data transfer capability, ...
