Tape or optical disc storage system might not always be perfect solutions for cold data storage, especially for cloud computing service providers, when there is no standard data center to deploy large scaled automatic mechanical equipments.

Alibaba coups with a similar situation in China for years. Before having enough own-built data centers, to store rapidly expended cold data in many middle-size and non-standard data centers, tape or optical disc solution is not the proper answer. To achieve high durability, low cost and flexibility at the same time for cold data storage, one of solutions from Alibaba is to build cold storage engine by cheap, low performance commercial hardware and simple open source software. We call this cold storage engine “Lambert” as code name, it simply runs sheepdog (an open source project for distributted storage) to manage huge number of SMR hard disks.
