For a long time

the core technology of storage equipment

such as SAN and NAS

belongs to some large enterprises abroad

in order to break this situation

and get involved core storage technology

our team from China Mobile conducted in-depth research and extensive practice. Use open source software

such as Ceph

as a technical basis

engineers can be more convenient and quick to cut into the storage areas

which technology is believed not easy to master. This article is to solve the practical problems that may be faced in the process of building a cloud storage platform using open source software

for example

high availability of storage clusters

deployment and maintenance of ultra-large-scale nodes

cross-data center solutions

and so on. We have adopted a number of technical means

such as adding front-end data cache

pre-backup data to improve processing efficiency; by enhancing data redundancy checks

data consistency detection to protect our data

enhancing health check and alarm module

automated deployment

optimizing the notification and polling mechanism

and enhancing the network monitoring technology to achieve convenient operation and maintenance management. We are able to achieve the goal of improving product availability by distributing all the storage components in a variety of racks of the same function.
