Green Venus Project

• Determine Scope
• Determine Specific Objectives
• Complete Design Documents

Assumptions

The system:

• must run Solaris
• may run on Sun Hardware
• must be connected to the Internet
• must be available 24x7
• may be configured as "High Availability"

(Can you tell I am a consultant Haha!!)

(Can you tell I was on RFC editing teams ahahah)

Scope Discussion

• Option 1. Basic green-er PC plugged into the grid in a standard data center environment.
• Option 2. Some power derived from Solar or wind.
• Option 3. Off Grid with Wireless hookup.

Option 1 Discussion "Green-PC"

This is by far the easiest, but from a challenge/bragging rights point of view, it does not do a lot except reduce dependency on electrical requirements.

Forecast Cost: $1000

Option 2 Discussion "Grid-Tied"

As far as "greener" ways.. this is by far cheaper and easier than a full off-grid solution.

Forecast Cost: $2500

Option 3 Discussion "Off Grid"

Off-grid creates some very difficult decisions, but also provides allot of opportunity and interest. From a research point of view, compelling, but difficult and expensive.

Forecast Cost: $5000

Evaluation Criteria

It may be interesting to develop a cost-benefit scorecard that includes the factors used to make a decision. These factors include but are not limited to:

High Availability

Partly as an exercise in running it, and partly to fit the 7x24 requirement, above, the system may be designed as an HA system, to allow very quick recovery from:

• network / power / facility unavailability,
• scheduled downtime,
• severe sysamdin error, or
• hardware failure.

The HA design could consist of the following components:

• two sites, geographically and network topologically separated
• software in cluster, perhaps STONITH configuration
• the abiity to turn off mirroring, patch server B, have the mirroring catch up with server A, then make Server B "active" and repeat with A.
