Default Cost of storage calculator?

The key to the answer is that the cost was expressed per GB *per year*.
One can probably buy a pretty decent storage system for well under
$10/GB these days, but the purchase cost typically represents only a
small fraction of the overall expenditu management costs are usually
ballparked at something like 5x - 7x the purchase cost (likely including
license costs but possibly not service costs), and license and service
agreement costs can easily more than double the raw hardware cost over
the life of the product.


And internal support/management si probably related to the number of
users. A video storage bank will have lower maintenance costs PER GB
than a database server or office data storage. Think about value of
data, volatility of data, number of users, changing requirements,
special software, etc.

Does NetApp and EMC charge per GB/year?

I have the same confusion when I started this project... I am guessing
it is the license cost we have to pay EMC and NetApp etc? Maybe other
hardware expenses? You need sometihng to plug the drive into
afterall...

Thanks for clarifying that for the group Bill, that is exactly the
point.
To really get a feel for storage costs you have to factor in the cost
of maintaining it over it time; usually acquisition (purchase) costs
are cheap comparitively.
Quick, simple example:
you purchase 10TB of storageX for $3GB.
Do you back this up? tape costs, library costs, people costs, offsite
storage costs
Do you make this highly available? datacenter costs, license costs,
monitoring costs
Do you replicate the data? license costs, capacity costs, network
costs

You can go on for a while like this. Just buying 10TB of disk is
simple, maintaining it over time is less so.

Thanks Bill and Faeandar ...

My next question is then, would a product aimed at reducing the amount
of storage consumed by a company look interesting?

If so, how would you go about calculating its ROI? How would you
justify it and compute how much it could save you money?

Or would you just be uninterested in reducing storage consumption
because of some other reasons (like its not a big pain point)...

Thanks Bill... wouldnt reducing the amount of storage have an impact on
the cost of managing that storage? I mean... simply having less data
to deal with should have a significant impact on the bottom line
spending right?

To add to my question Bill... I guess what I am getting at is... while
cost of storage itself is decreasing, isnt it the case that the amount
of storage an enterprise consumes is generally on a rapid increase?
And that offsets the decrease in the cost of storage...

So the product (storewiz) we are evaluating is one that would optimize
drastically (up to 60%) of the data entering the primary storage
servers...

The value proposition is that having less data implies less overall
costs wrt hardware and management.... and we for example dont have a
steady amount of data... its always (every quarter) growing by many
gigs (if not TBs)

So one example that we got from the vendor was something along the
following lines... sort of an ROI calculator (my original topic)...

In this case, the company was addng about 25 - 50TB a month of new
data... the company uses an FA960e (which costs about 225K with out any
shelves populated) and can host about 84TB max (raw space... logical
space when taking RAID1 into consideration is much lower... around
50TB)....

So for a company with growth like that, I guess such a product would
make sense? I guess... based on your comments Bill and Faeandar, would
it be accurate to say that reducing the amount of storage entering the
primary storage is only valuable if the company has a huge growth rate
of new data?
