Solar Powered Network – Part Two


This is a basic diagram of how the data center network is laid out:

Hosting A Cleaner Future

Power is generated using 120 solar panels located on two large sets of arrays (1), one on each side of our data center. The solar panel arrays face due south, which will generate the most possible amount of electricity. The power from the solar panels is DC, which is converted to AC through our sunny boy inverters (2). After it is converted using the inverters it is stored in our battery bank (3). It then leaves our battery bank and runs through out our data center and offices including the air conditioners (4). In case of an emergency we can get power from our generator but it is not necessary.

The actual solar powered setup is more involved, but this will give you the general idea of how it works.

Redundant Solar Powered Servers

All servers are clustered together and each server has two separate SAN HBA cards that give the server redundant conductivity to the SAN. Our Storage Area Network (SAN) is a high-speed sub-network of shared storage devices. These storage devices are machines that contain nothing but RAID hard disks for storing data. The SAN’s architecture works in a way that makes all storage devices available to all of the clustered servers. Because the data does not reside directly on any of the clustered servers, any server can go down and the other servers in the cluster will take over and balance the load. The diagram below shows you how each server is connected to the SAN via redundant SAN HBA cards, redundant connections to the SAN switches and redundant SAN system. All of the servers are running within VMWare’s virtualization technology to reduce cooling and electrical requirements with a 30:1 ratio of virtual servers to physical servers. Both our servers and the dedicated servers use the same redundant server infrastructure and virtualization technology.
