User Requirements

Open-source and Interoperability

The open source-based cloud platform has obtained attention since it was born. With healthy ecosystem of standard IaaS constructed by OpenStack and other open-source community, vendors who are in pursuit of project agility, technical force aggregation and long-term self-controlled product leverage such open-source framework as main architecture for “Cloud OS”of scaled IaaS to build enterprise dedicated cloud or cloud platform for application industry.

Full-distributed Architecture

To realize VM block mirror management, mirror warehouse and data backup, major part of users select Ceph as underlying storage module for Cloud scenarios with KVM. Ceph is a mainstream open-source distributed storage platform which is widely used by large-scale internet and HP computing carriers and is now in vigorous development. The community led by Ceph foundation provides good technical ecosystem with deep involvement of various HW and OS leading vendors, ensuring the advantage of Ceph modules technology and outstanding interoperability among vendors.

Production and SLA

However, the adoption of native Ceph by enterprises is limited by the following problems:

  • Operations and maintenance are conducted by command lines to a large extend, presenting obvious low-efficiency
  • Deficient integration with enterprise-level HW and application ecosystem, highly depending on development
  • Lower level of single-point performance and SLA compared to traditional storage
