Linear Scalability

The distributed architecture ensures that both the storage capacity and performance scale-out linearly as the number of nodes or disks increases and can be easily expanded to thousands of nodes and EB-level capacity to meet the needs of cloud business expansion.

Flexible Cache Tiering

A cache tier provides Clients with better I/O performance for a subset of the data stored in a backing storage tier. The ONEStor 3.0 not only enables you to gain linear increase in performance by adding nodes, but also offers the following deployment modes so you can make the best use of storage resources on each node:

SSD+HDD

All SSD.

All HDD.

In SSD+HDD deployment mode, you can deploy disks as follows:

Deploy HDDs as data disks to store data and deploy SSDs as read and write cache disks to accelerate reads and writes.

Place SSDs and HDDs in different storage pools to fulfill tiered storage.

The SSD+HDD deployment mode has been widely used as it combines the high IOPS and throughput capabilities of SSDs with the high capacity and low cost benefits of HDDs.

Feature-rich Enterprise-class SDS

Data Replication (copies): Data replication (or copies) can ensure the reliability of data. Clients can fulfill the desirable data reliability by setting the number of replicas in the replication redundancy policy. The ONEStor 3.0 will automatically distribute the replicas in the cluster based on your settings to maximize data reliability. Data will not miss as long as one replica is available.

Erasure coding: Support K+M erasure coding with multiple redundancy schemes, reducing TCO effectively. For example, in the 4+1 erasure coding method, data is still available when only one server in the failure or downtime, and the system can recover the lost data through the original data and the check bit.

Rapid data reconstruction: ONEStor 3.0 supports parallel and fast fault handling and data rebuilding. When there is some nodes or disks failure, the system can automatically reconstruct these data in other available places, and the data reconstruction time can less than 20 min/TB.

Robust data consistency: The ONEStor 3.0 ensures all data replicas are absolutely identical, providing the highest data consistency. The data write action will not be considered successful until all data replicas successfully write on disk, making the reliability of user data in priority to ensure the highest reliability of user data.

Data protection: Comprehensive data protection and disaster recovery abilities such as: snapshots, volume copies, QOS, remote replication, fault domains, protection domains, etc.

Automated Operations and Maintenance

Automated and rapid deployment of storage clusters, including batch deployment, single node increase or decrease, single disk increase or decrease, etc.

The automatic monitoring and alarm system can quickly identify and troubleshoot problems in real time when a failure occurs and improve the efficiency of operation and maintenance.

End-to-end monitoring capabilities provide comprehensive performance and health monitoring from physical servers to storage pools, including monitoring CPU, memory, NIC, reading and writing IOPS, reading and writing bandwidth, time delay, and component health status.

Flexible node deployment and configuration in adaptation to hardware capability maximizes hardware resource usage.

Conveniently perform fault domain isolation and flexible selection of data storage locations to improve the reliability of business applications. Support host, cabinet, and the data center three-level fault domain and automatically generated the cluster device topology.

The system is self-healing and supports automatic data rebalancing when a storage node or disk fails, is added or removed.

Advanced AI algorithms can predict the failure of hard disks. When the system indicates that the disk may fail, the system automatically generates an early warning message to notify the administrator to replace the disk in advance.

Complete Log management capabilities. Administrators can customize the period to export Logs. The Log includes cluster software and hardware adjustment information, network operating status, heartbeat status, storage pool status changes, user behavior records, etc.

Comprehensive audit capabilities ensure system security. The audit content covers all system operation records, and the storage console supports SSL access encryption.

A unified management Web-based portal visually displays the cluster topology status, equipment information (data center, rack, server, NIC, etc.,) abnormal component events, monitoring history, etc.

Software Compatibility

Supports servers from mainstream X86 manufacturers such as Dell/ Inspur/ H3C/HPE/Huawei and can adapt to X86 servers according to requirements.

Supports mixed disk combination in storage pool.

Support integrated with CAS, VMware ESXi 6.7U2, ESXi 6.7U3, and ESXi 7.0.

Block Storage

ONEStor 3.0 creates local server-based SAN storage through storage virtualization technology, provides standard interfaces such as iSCSI, supports a wide range of virtualization platforms (VMware, CAS) and database applications, and meets the SAN storage requirements of virtualized resource pools, desktop clouds, databases, container and other scenarios. Besides, ONEStor 3.0, as the core module of UIS (HCI product), can provide storage services for CAS (virtualization) in a converged way. ONEStor 3.0 can provide block storage services for cloud VM’s volumes for multi-tenants.

File System Storage

ONEStor 3.0 provides standard interfaces such as NFS and CIFS to provide users with unstructured data shared storage resources, which are used in multiple business scenarios such as big data, storage for video/audio, etc.

Object Storage

ONEStor 3.0 is compatible with Amazon S3 and OpenStack Swift, supporting integration into mainstream cloud computing ecology, and meet the service requirements of cloud backup, cloud archiving and cloud storage, etc.
