35μs Delay, 400 Nodes Managed by a Single Volume
LoongShine LeoStor adopts the Gen3 converged architecture technology, the excellent parallel algorithm, and the storage technology of" direct storage hard disk without SSD cache" make the data storage more reliable. The advanced erasure code technology, with performance comparable to the replica mode, can obtain up to 94% of the available space, and save customers' investment costs.
Based on the design concept of software-defined storage, LeoStor can highly adapt to x86 platform server platforms such as Intel, AMD, Megacore, and Haiguang.Feiteng,Kunpeng and other ARM server storage platforms, as well as compatibility The V4 and V10 versions of the Galaxy Kirin operating system have obtained compatibility certification.
Technical characteristics
Loongshine LeoStor is a next-generation unified storage system that integrates "file", "object", "block" and "big data". NAS and object files can realize data interoperability. The system has rich storage protocols, and supports hard quota and permission management and restful based on directory and user API interface, which can be deployed as multi-tenant, high-performance cloud storage.

Based on the global unified view file system conforming to POSIX standard, there is no need for secondary development or recompilation. From R&D to production, users can use a set of applications, making the R&D of high-performance computing easier; At the same time, LeoStor supports HDFS interface, and the big data analysis software originally running on Hadoop can run on LeoStor parallel storage system without secondary development.
LeoStor supports replica and N+M: M erasure code data redundancy model, with a maximum storage utilization of 94%. N+M: M erasure code technology not only supports the protection of M nodes (ServerRaid), but also supports the protection of M hard disks (DiskRaid), leading competitors and Ceph series technology.
LoongShine LeoStor has powerful directory management technology, which can independently design redundancy mode, hard quota and permission scheme for each mounted directory; Support hierarchical storage technology, which can divide hard disks with different performance such as mechanical disks and SSD disks into different directories, or automatically migrate SSD hierarchical data to SATA disks according to the data lifecycle strategy, and the original access path remains unchanged; At the same time, data can be automatically archived to "near-line warm disk storage" and "offline Blu-ray storage" through data lifecycle strategy.
LoongShine LeoStor can hook up almost all storage devices and server devices in the network, including traditional FC-SAN, IP-SAN storage devices and storage servers.Use LeoStor tiered storage technology, which can benefit almost all old devices, through powerful LeoRaid data protection mechanism performs cluster protection of hard disks and nodes, and can fail up to four nodes or four hard disks at the same time. In combination with LeoStor's rich storage output protocol and file quota management, old devices will be rejuvenated.
Single node / Multiple nodes / Mute / Full flash / mass
The LoongShine LeoStor DF storage node adopts a soft and hard decoupling scheme. The hardware scheme is very flexible. It can be adapted to its own LongShine hardware equipment, as well as third-party Lenovo, Dell, Supermicro, Sugon, Seagate, PowerLeader, Tianxin Gu'an and other hardware products, as well as Datang, Dapu Micro, Changjiang and other domestic hard disks.
LoongShine DF storage nodes can be deployed into single-node scheme and multi-node cluster scheme, and the number of nodes can range from 1 node to 4096+nodes. Among them, multiple storage nodes can form a symmetric cluster scheme or cooperate with DF-MDS metadata nodes to form an asymmetric cluster scheme.
