 The problem of traditional server
 The innovative Micro Server Architecture
 Our ARM Micro Server
 The Rack solution
 Software Solution
 The advantage
 Case Study
 Warranty and Service
 Backup

3. The problem of traditional server
 Not power efficiency: generate a lot heat waste
 High power consumption
 Single CPU performance is too powerful to do a single
task. Need to virtualize it to many small virtual machine.
 Single point of failure cause big failure: One single server
attaches many storage devices.
 Use hardware redundancy to maintain its reliability cause
a high cost on hardware
 High maintenance/operation cost

4. Our innovative Solution
 Use good enough performance ARM SOC to build a very
high power efficient micro server. Consume low power
and generate very few heat waste
 Every single micro server attaches only one storage
device to minimize the influence of a node failure
 Build the cloud with Ethernet fabric linked micro servers.
 Physical micro servers to perform distributed storage and
computing
 It must natively support Linux to enable the using of
existing open source cloud software such as Glaster FS,
Ceph and Hadoop etc.
 Software defined redundancy

5. Our Micro Server: CyOne
CyOne is a complete server with
 CPU: 1GHz ARM v7 32-bit CPU, (Marvell
Armada 370)
 Memory: 1GB DDR3, 128MB Flash
 I/O: dual Giga bps LANs, 2 x SATA 2
interface
 Tinny Size: 3.5 x 8.8 cm
 Very Low Power:
 1.7 Watts @ regular operation
 2.5 Watts @ full load

12. The Innovative Micro Server Architecture
The concept of Cy7 ARM server is similar to the concept of Hadoop. It is a 1U height chassis
accommodates 7 micro servers (CyOne). Each CyOne is a independent and complete server
with 1GHz ARM v7 CPU, DRAM, NAND flash, 2 Giga LAN and SATA 2.0 interface. Sure every
CyOne have its own IP address.
Each CyOne micro server attaches only one storage device. The storage capacity and
computing power is aggregated by installing numbers of CyOne. The system architecture of
the storage system is build by as many as Cy7 you want with Ethernet. There is two Giga bit
ethernet switches on the backplane to connect the CyOne and provide two Giga bps uplinks.
By connecting Cy7s to external switches, you build the cloud storage cluster.
The storage capacity and computing power is linearly proportion to the number of CyOne
and HDD you put. The CyOne micro server runs Linux so you can use any existing open
source cloud software such as Gluster FS, Ceph, Hadoop or Open Stack easily. Certain it also
support Ubuntu, Debian, Red Hat file systems.
The redundant of the data and servers are all done by software. Data backup and computing
tasks are distributed to different nodes in the cluster. That is why the cloud can be no single
point of failure.
When any node fails in the cloud, it won’t affect the healthy of the cloud. You don’t have
the urgency to fix a single node failure. Only scheduled maintenance is required. So it
reduce your maintenance cost a lot.
