Overview
Welcome to Dedicated Distributed Storage Service API Reference. Dedicated Distributed Storage Service (DSS) provides you with dedicated storage pools which are physically isolated from other pools to ensure high security. With data redundancy and cache acceleration technologies, DSS delivers highly reliable, durable, low-latency, and stable storage resources. By flexibly interconnecting with various compute services, such as Dedicated Computing Cluster (DCC), Elastic Cloud Server (ECS), and Bare Metal Server (BMS), DSS is perfect for different scenarios, including high performance computing (HPC), online analytical processing (OLAP), and mixed loads.
This document describes how to use application programming interfaces (APIs) to perform operations on DSS resources, such as creating, querying, deleting, and updating DSS resources. For details about all supported operations, see API Overview.
If you plan to access DSS through an API, ensure that you are familiar with DSS concepts. For details, see Service Overview.
After the storage pool is deployed and becomes available, you need to create disks in the storage pool. For details about disk APIs, see Elastic Volume Service API Reference.
