While I am tied by NDAs and wished I could talk about some of the future products I am working on. As those new products become public I will talk on how they help to make Storage GREENER.
One of the reasons I got motivated to revive my blog is that I was challenged by a customer some days ago. Here is what the customer told me as we were talking on the phone:
-Carlos, I am right here looking through the window of my office down the street and thinking on what I was told by the representative of the Electric company that just left my office: "If you put a power substation down there, at the street level, I can add more power to the data center located two floors above us. Or you can move your data center to XYZ location and we can provide you all the additional power you need".
I will spare you from the whole conversation but needless to say I got this customer in touch with the people that work on BIG GREEN.
After satisfying this customer needs and hearing over and over the phrase MAXIMUM EFFICIENCY it daunted on me that much of the work on data centers has been done mostly on heating and cooling and every day more virtualization is used for optimal server use.
But the question is:
efficiency may be something that some customers pin point on one and only one point of view (perception) some examples are:
- Capacity and its usage
- Performance and the response time (latency)
- Energy usage
- more examples can be written but I think you get the picture..,
In general I can say that storage customers just recently (in the last 2 to 3 years) started looking at ENERGY CONSUMPTION as one of the efficiency factors for storage. What are they looking at?
initially two factors:
BTUs (temperature) emitted.
KWH (electrical energy) consumed.
If I start thinking on what is efficient then I would like to see a storage system that has all these attributes:
- High performance
- High capacity
- Runs cool (minimal BTUs)
- Runs on low wattage (minimal electric energy)
- Its small and
- Is low cost
Finally and with the current technologies, in my personal opinion ANY data center admin should look the next three things for each of their storage units:
- IOPS/watt for the full system when running at peak time. This number will indicate how much work your storage system is capable to do for the amount of energy used.
- MBPS/watt for the full system when running at peak time. This number will indicate you how much data you are moving with the energy used
- GB/watt on idle (let me make emphasis on idle and NOT deep-idle). This number will tell you how much energy is being used to have the storage system ready to go, or like a good friend says, how much money are you paying for something to do nothing?
