ZStack Ceph

Continuously, Linearly Increased High Performance

Performs in-depth code optimization at critical stages based on the industry-leading strong consistency hashing algorithm. This way, the performance grows linearly as the nodes increase, meeting the performance requirements in scenarios such as cold and hot data switching.

IOPS: 1,000K+

Service Quality Assurance

Modifies the storage volume QoS in real time and dynamically allocates performance resources to cope with tidal scenarios.

Reliability Guarantee

Provides multiple levels of data protection for storage clusters, effectively ensuring the reliability and continuity of the storage system.

Multiple copies of data

Strong data consistency

Cluster without single point of failure

Parallel copy recovery

Extensive Customer Application Interfaces

Supports multi-interface access and multipath I/O (MPIO). Multiple gateway services can achieve load balancing (LB) to ensure high availability of the system.

High Usability and Manageability

Provides rich visualized management features, considerate management process, web-based, visualized installation and expansion, and other features such as RESTful APIs, command lines, disk SMART information, capacity warning, historical monitoring, log, and alarm.

Storage Acceleration Engine

Improves the system read performance by an acceleration engine with high performance and multi-level caches. Increases the system read/write performance in OLTP scenarios via the intelligent I/O coalescing algorithm and popular data analysis algorithm.

SSD Cache

Advanced Storage Features

Builds a high-level data protection mechanism with instant snapshot ROW, linked clone, EC, multiple copies, and failure domain, and enables proper hardware resource utilization with thin provisioning, space recycling, and hierarchical storage.

Instant Snapshot ROW
When the source system receives a data write request, it redirects the updated original data pointer in the data pointer table of the source data volume to the new storage space.
Multiple Copies
All data is stored as multiple copies and distributed on different storage nodes. The business continuity is not affected if a single storage node is damaged. The number of copies is configurable.
Thin Provisioning
Provides applications with more virtual storage resources than actual physical storage, which significantly improves the storage space utilization.
Linked Clone
Creates multiple volumes based on one volume snapshot. The cloned volumes have a pointer that points to the original volume snapshot. Therefore, modifying a cloned volumes does not affect the original snapshot.
EC
Ensures data reliability via a small amount of redundant information and exchanges more spaces with the CPU computing time. This obtains more effective storage capacity than the multi-copy mechanism.
