Mars 400 ARM based 8-node Micro Server Cluster

Mars 400-Series by Ambedded
Unified Virtual Storage Manager (UVS)

Starline has added the smart Mars 400 server model from Ambedded to its range. The 64 bit servers working with the modern Ceph system have a lot of advantages, starting with self-healing data sets and unlimited scalable capacities up to an extremely low power consumption.

The concept of the grand Mars 400 series from Ambedded is based on three pillars: The innovative unified storage solution Ceph, its specially developed, extremely economical ARM servers with eight independent microservers and finally the matching user interface called Unified Virtual Storage Manager (UVS).

Ceph provides a distributed open source file system with access to object, block and file storage. The storage system also protects the data stock by intelligently and economically distributing and replicating the individual fragments. The developers paid particular attention to the scalability of the systems: Within the Ceph world, a cluster is not subject to any restrictions. If storage space is required, it is sufficient to screw additional servers into the rack. The Auto Load Balance function ensures that the data is evenly distributed to the booked drives.

ARM server
The slim, award-winning server from the Mars 400 series from Ambedded make full use of Ceph's flexibility and top it all out: The Mars 400 server, which are equipped with eight ARM dual-core processors and the eight SATA drives (HDDs and/or SSDs) connected to them, form a complete cluster of eight microservers. If one of the hard disks or micro-servers fails, the intelligent controller automatically regenerates the data and writes it to the remaining data carriers in parallel.

The intuitive graphical management interface provides a quick introduction to Ceph. Even inexperienced users can create a cluster within 30 minutes. In the so-called dashboard, the administrator allocates virtual memory and manages user keys, for example.
