Dedicated Enterprise Storage Service (DESS)

DESS provides the same performance and reliability as an enterprise private cloud, including a stable and low latency of 0.5 ms and high availability of 99.9999%. This ensures that core enterprise applications, such as Oracle RAC and SAP HANA TDI, can run on the public cloud.

The open beta test (OBT) of DESS will be held in October 2017,Coming soon…

Product Advantages

Dedicated storage

Storage devices on Huawei Cloud are dedicated for customers. Each tenant has one or multiple sets of enterprise storage devices, which are not shared by other tenants. In addition, tenants are provided with various types of storage devices, so they can select storage devices of which the performance meets the service load requirements as needed.

Enterprise-level features

0.5 ms latency, ensuring a quick response speed for transaction, query, and analysis services.

3000 IOPS/TB in the typical database performance model, supporting a large amount of concurrent access.

30-minute service provisioning

For traditional storage devices, it generally takes several weeks even months to purchase, install, and commission them. DESS greatly shortens the service rollout time, improving the operation efficiency of enterprise services.

Application Scenarios

  • Security and supervision scenarios

  • Core database scenarios

Security and supervision scenarios

Scenarios

Security and supervision scenarios

Characteristics

  • In industries such as finance and security, customers have high compliance requirements for service deployment, and some of them may also have strict requirements for data security. On this occasion, physical storage devices must be deployed to ensure dedicated resources and data isolation for monitoring and tracing.

Recommended configuration

BMS ECS

Core database scenarios

Scenarios

Core database(Oracle RAC etc.)

Characteristics

  • Some customers do not allow their core database services to be deployed on VMs, but deployed on storage devices that offer dedicated resources, support network isolation, and provide stable performance.

Recommended configuration

BMS ECS

Function Description

Physical isolation

Physical storage resources on Huawei Cloud are dedicated for tenants, so the created DESS can be provided by the isolated storage devices.

Various computing services and storage device models

ECS and BMS connections are supported, and both common and high-performance storage devices are supported, meeting the requirements for small- and medium-sized common databases as well as core databases such as Oracle and SAP.

Enterprise-level features

0.5 ms to 1 ms latency and 3000 IOPS/TB in the typical database performance model.

RAID TP mode

The data reliability and service continuity of a single storage system are not affected even if three disks become faulty, implementing data reliability assurance of 99.9999% (2018 H1).
