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.
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:
XCBS（XSKY Cloud Block Storage）存储是由 XSKY 开发的企业级分布式存储产品，对开源云环境做了深度优化。 相比社区版上游软件，XCBS 分布式存储系统在稳定性、性能、可靠性、易用性等方面进行了深度优化，实现可视化、自动化运维， 为大规模云环境提供了可靠的存储基础架构支撑。
Deep mutual authentication with open-source cloud platform vendors, deployed as hyperconvergence or storage pool
Dramatically reduce IO latency and linkage jitter compared to community Ceph with the same HW configuration
Visualized DevOps and troubleshooting and fine cluster management at HW-level
Interactions with Open Source Community
No change on architecture, seamless replacement of open-source Ceph
Dramatic improvement on performance, reduction on O&M complexity and lower TCO
Enhanced enterprise features for higher security
Online migration solution for seamless data migration from Ceph to XCBS
Rich cloud-native protocols provide persistent block storage service as well as object storage service to diverse data types.
