BlockStore distributed block storage-Shenzhen Kunlunfeng Trading Co., Ltd.

The new generation of enterprise-level distributed block storage

is a software-defined universal distributed block storage product that uses cloud native technology encapsulation and decentralized Shared-Nothing software system architecture. GStore can meet the data storage needs of various applications such as small and medium-sized OLTP/OLAP databases, cloud computing and virtualization, cloud desktops, file sharing, etc., and is optimized in terms of performance, functionality, reliability and ease of use.

It summarizes and absorbs the industry’s engineering experience and latest technological achievements in distributed storage, cloud storage and other fields from 2011 to 2020, and is constructed using a newly designed distributed storage engine, cloud native technology, combined architecture, etc. It can also seamlessly evolve to a hybrid multi-cloud data platform by combining service components.

Features

Smooth performance experience

Using SATA/NVMe SSD as data read and write cache, this mechanism greatly improves system data read and write performance through a series of technologies such as data read hotspot optimization, data pre-reading, small IO merging and large IO pass-through to main memory; GStore data The cache relies on innovative intelligent IO scheduling algorithms and resource orchestration algorithms. Even if the cache space is fully loaded, the storage system can still maintain a high level of overall performance, and throughput and latency will not decrease;

Provides volume-level QoS (Quality of Service) control capabilities. Users can set IOPS or bandwidth threshold limits for each storage volume to ensure that each storage volume can provide a performance experience that meets actual business needs. Each storage volume can also set an elastic water level for sudden performance peaks. Even if there is a sudden increase in IOPS or bandwidth during business operations, the system can dynamically allocate resources to meet performance requirements.

Open and compatible ecology

Provides iSCSI block storage interface, users can seamlessly migrate business applications using traditional block storage to GStore;

Provide RBD interface to connect to OpenStack ecosystem;

Provide VAAI interface to connect with VMware ecosystem;

Provide CSI interface to connect to K8S container ecosystem;

Supports co-clustering of servers of different brands and generations to unlock specific hardware.

Enterprise capability support

It supports enterprise-level advanced features such as instant volume snapshot, volume clone, volume copy, online volume expansion, volume backup, automatic thin provisioning, etc. It
supports iSCSI multi-IO path capability and provides up to 6 MPIOs to achieve Active-Active dual-active access.

Multi-level safety and reliability

Provides two data protection strategies: EC erasure coding and data multiple copies;

Support hard disk and network sub-health detection and self-healing;

Support end-to-end DIF;

Supports iSCSI CHAP two-way authentication, data transmission encryption and operation and maintenance operation logs.

Composable architecture supports continuous evolution

Based on the combined architecture and on-demand service model of the hybrid multi-cloud data platform, various service components can be subscribed to achieve iterative evolution from a single block storage system in a single data center to a big data storage system, container storage system, NAS File system, object storage system, data lake platform, data management platform, data service platform and even a complete hybrid multi-cloud data platform spanning data center, multi-cloud and edge.

Sub-health management

Based on the intelligent multi-dimensional sub-health management system, it supports the detection and processing of sub-health faults at various software and hardware levels. It can automatically detect node, hard disk, network card or software faults and automatically alarm, and can provide pre-processing solutions according to the alarm level. Maximum Prevent missed detections and negative reports to ensure safe and stable operation of the system.

Data reliability

Provides multi-copy level data security and reliability data protection mechanism, supports multiple QoS policies to protect business continuity and stability. At the same time, when a node or disk fails, the storage system will automatically complete reconstruction, and the reconstruction efficiency is <15 per TB. Minutes, different QoS policy priorities are used to ensure data reliability while meeting the business's maximum performance requirements.

Customer benefits

Only one copy of data is stored within the enterprise, with intelligent management and cost optimization.

A data platform that can be scaled horizontally and continuously is sufficient to store all enterprise data and provide rich protocol interfaces and data service capabilities.

Easily build, deploy and operate various application systems based on the "hybrid multi-cloud + edge" infrastructure environment

Data “originates on the cloud, grows on the cloud, and is applied on the cloud”

The composable architecture allows enterprises to build their next-generation data infrastructure in a more agile way. They can start from a small scale, closely integrate the construction process with the business, and expand on demand.

Enterprise IT shifts from focusing on infrastructure to focusing on business and data, and shifts from operation and maintenance to providing data services

Build the next generation of intelligent data infrastructure to gain new impetus for business growth.
