Torch Object Storage

Overview

What is TOS

Torch Object Storage (TOS) is a distributed cloud storage service provided by Volcano Engine. TOS offers near-infinite scaling, cost efficiency, ease of use, and data security, reliability and availability. You can access TOS through RESTful APIs, software development kits (SDKs), and various tools. With TOS, you can manage and access your data over the network from any application, anytime, anywhere.

What are the benefits of TOS?

Massive scalability

TOS boasts proprietary distributed object storage technology, leading-edge architecture, and top-notch technical support. With the ability to house tens of thousands of object storage servers, it enables quick scaling for exabyte loads. Traditional, self-built object storage systems have several limitations. They have restricted scalability with node capacity and difficulty meeting expansion demands of 100 PB or more. They have bottlenecks in bucket and object metadata management and low concurrent write performance per bucket. They also have constraints on the number of objects per bucket. By contrast, TOS provides virtually unlimited storage capacity per bucket, enabling you to easily manage and store large amounts of data.

Enhanced data durability

TOS adopts a distributed architecture that stores redundant copies of each object on different devices within the same region. This ensures high data durability, even during hardware failures. It regularly verifies data integrity through checksum validation to promptly detect any corruption caused by hardware issues or other reasons. When partial data corruption or loss is detected, TOS automatically repairs and reconstructs the damaged data using redundant copies. Additionally, TOS supports cross-region data replication for geographic disaster recovery. The service delivers exceptional data reliability of 99.9999999999% (twelve nines).

High data security

Data is protected at multiple levels. Access control policies, such as Access Control List (ACL), are provided for all buckets and objects. All connections are encrypted using Secure Sockets Layer (SSL). The system authenticates users to ensure data security.
