Referring to fig. 1, the hardware system of the ARM storage server according to the present invention adopts a modular design, and the whole machine is composed of a structural chassis, a storage node, a back plate, a network switch board, a BMC management board, a fan module and a power module. The system architecture is logically divided into four parts from the business process: the system comprises a storage system, a network switching system, a BMC management system and a power supply and heat dissipation system. The four systems work cooperatively and are combined into a complete storage server complete machine system, and the BMC management system carries out unified operation and management on the server.
The invention provides a full flash ARM storage server based on a distributed storage hardware architecture, which comprises a storage system, a network switching system, a BMC management system and a power supply and heat dissipation system, wherein the storage system is connected with the BMC management system;
1. storage system
The storage system is physically realized by 12 storage nodes, which are distributed in 4 rows and 3 columns in a 2U chassis, and the storage nodes adopt pluggable modular design. The front view of the server is shown in the following figures:
| node 1 | Node 4 | Node 7 | Node 10 |
| Node 2 | Node 5 | Node 8 | Node 11 |
| Node 3 | Node 6 | Node 9 | Node 12 |
The storage node controller is realized by a low-power-consumption multi-core (4 cores or 8 cores, and more cores are possible in the future) ARM processor, and the ARM processor can select a 4-core or 8-core processor of Marvell and other companies for integrating the tera network card and the SATA controller; the 8-core ARM processor of the PCIe and SATA controllers integrated by the Rayleigh core micro-and other companies can be selected, and the tera-network can be adapted to the tera-network card chip expansion through the PCIe bus.
The storage system is accessed into the network switching system by adopting a tera or a bi-tera network (the bi-tera network can realize redundant backup of the network switching system through a bonding technology), and performs data transmission and service communication in a network switching mode; communication with the BMC management system through a management bus interface (UART, I2C, control IO signals, etc.); 2 hard disks are accessed through 2 SATA bus interfaces, so that the data access function is realized. The storage node main board is connected to the 2U server backboard through an onboard node connector, and each storage node can control 2 hard disks: the disk bit 1 is directly expanded by the SATA connector on the motherboard, and the disk bit 2 is expanded by the SATA adapter board (or adapter line) and the SATA expansion board. The hard disk position structure is compatible with two physical size hard disk specifications of a 3.5 inch mechanical hard disk and a 2.5 inch mechanical hard disk/SSD solid state hard disk. The hardware architecture of the storage node is shown in fig. 2.
2. Network switching system
The network switching system is realized by network switching boards carrying high-performance tera-network switching chips, and each network switching board is equivalent to a built-in high-performance tera-network switch. The switching chip needs to support at least 240Gb of switching capacity, namely, the bandwidth of a downlink (carrying out data switching transmission with 12 storage nodes) network is 120Gb (12 x 10 Gb), and the bandwidth of an uplink (carrying out data switching transmission with an external service network) network is 120Gb as well, so that the non-blocking forwarding of data can be realized in the most extreme application scenario. Considering the realizability of the product, the upper network port can be realized by adopting 5 25Gb SFP28 optical ports through a port link aggregation function.
If the redundancy backup function of the exchange boards is needed to be realized, 2 exchange boards can be adopted, and 12 10Gb lower network ports of each exchange board are respectively connected with 1 10G network ports of 12 storage node mainboards; the 2 10Gb network ports of the storage node main board adopt Bonding technology to make redundancy of a network port hardware layer, single point failure of single network port application can be prevented, an actual product application scene can be configured into a Bond mode 1 (namely a main standby mode), only a main network card works in the mode, a backup network card does not work, and only when a main network interface fails (such as a switching board corresponding to the interface fails), the system starts the backup network card to work according to configuration, so that equipment can still serve outside, and a failure protection function is achieved. The network topology of data exchange transmission between the network exchange board and the storage node is shown in fig. 3, wherein the 2U back board only plays a role of a physical carrier for signal interconnection for network signals, and does not participate in any signal conversion.
Through the two-layer Ethernet switching function of the network switching system, not only can the high-speed data switching transmission between the storage nodes be realized, but also the high-speed data switching transmission between the storage nodes and an external service network can be realized, and the purposes of high-speed data access and backup restoration are achieved by matching with the high-speed IO performance of the SSD.
If the network performance needs to be further improved, the 2 network switch boards can be logically combined into one network switch board through a switch stacking technology. Through the stacking technology, high reliability of the network and large data volume forwarding of the network can be realized, and meanwhile, network management of the switching board is simplified. Meanwhile, the network bandwidth of each storage node can be doubled (namely, 20Gb is reached) by matching with the double-megamega network card bonding technology of the storage node; likewise, the upper network bandwidth of 2 physical switch boards (already combined into one logical switch board by stacking technology) is doubled by the link aggregation function. The network topology for data exchange transmission between a network switch board and storage nodes using stacking techniques is shown in fig. 4.
3. BMC management system and power supply and heat dissipation system
The BMC management system is based on BMC management board hardware, the running of the BMC management system is independent of a server service system, and the BMC management system can run by itself only by plugging a power line into a server, and is used for implementing functions such as server remote control management, hardware state monitoring and the like. The BMC management system bus comprises UART, I2C, ethernet, low-speed IO control signals and the like, and achieves the functions of collecting state information and controlling and managing the storage nodes, the network exchange board, the power module and the fan module.
The power supply and heat dissipation system consists of a server 1+1 redundant power supply module and a fan module, and the functions of centralized power supply and active heat dissipation of the server hardware system are respectively realized, so that the whole hardware system is always in a healthy working environment.
The BMC management system and the power and heat dissipation system are not core technologies of this patent and will not be described in detail herein.
Referring to fig. 5, a rear view of the server is shown, and the BMC management board, the network switch board, the power module, and the fan module are all configured in a pluggable modular design.

The storage controllers of the 5.12 storage nodes are all realized by adopting low-power-consumption 4-core or 8-core ARM processors, so that the functions of equipment can be effectively reduced, and the balance between the performance and the power consumption is achieved.
