Proposed Demo Architecture
With different characteristics of Renewable Energy,
we can decompose a datacenter into Computation, Network Flow, and
Data access. Computing servers consume most of the power but can be
leveraged by Virtualization or other Computer Techniques to shift the
services across datacenters while network and storage equipment take
less power. This is critical to the users, but needs long-term access
so computing servers can be supplied with wind turbines or hydro dams
which provide the power at KWs level, while network and storage
equipment can be supplied with Solar panels which provides the power
at 100Ws. For computing servers, as the renewable energy is not
dynamic and inconstant, Virtualization can be leveraged in both
shortage and outage cases and Service Scheduling Components will be
in place to manage the computing services: 1. In power shortage
cases, Virtualization can dynamically consolidate the services in
fewer Servers while shutting down some servers 2. In power outage
cases, Virtualization can dynamically migrate the services to another
Datacenter to escape the shutdown datacenter For storage equipment,
the low-powered but long-lasting renewable energy can still maintain
the data access through network. So the proposed Demo Architecture
will look like the diagram as below:
In the above proposed architecture:
- Each GDC center has been equipped with Networked Attached storage.
- Power Predicator (Power management) will keep updates of the green energy stats information to the Service Scheduler. It has two main roles: one is notifying the Service Scheduler in advance when Datacenter’s power outage is coming and the other is predicting the power supply strength.
- Based upon the updates from the Power predicator, the Service Scheduler (Service Management) will make a decision on how to move the services across datacenters and what strategies will pertain for each service in the power shortage and outage.
Proposed Hardware Specifications
With the current project budget, we plan the following: each
rack-mount server represents a mini-datacenter with virtualization
deployed. One mini-datacenter supplied with Green Energy, and the
other mini-datacenter supplied with Grid Power. Power Predictor will
predict the power of Green-energy-driven datacenter and Service
scheduler will decide when to shift the computing service onto and
off GDC. This system will include:
- 1. 1x HP Proliant DL385 with 1200w DC as Green-DC
- 2. 1x HP Proliant DL165 with 750w AC as Grid-DC
- Both of them include two AMD Operon 6220 3.G CPUs and 64G Memory.
- AMD Operon 6220 supports AMD-V Virtualization Technologies and VMware EVC mode.
- 3. 1x Iomega StorCenter px4-300r Server Class NAS
- Px4-300r supports both NFS, Samba, and iSCSI
- Maximum Power Assumption at 170w
- px4-300r will be equipped with GDC, hosting VM images
