Can some one help me with the math here?
-
Can anyone tell me what they think the equivalent $$ Savings of trimming 8 TB of data from a mail server farm might be, assuming a large server farm and an estimated total load of 800 TB prior to purging the 8 TB?
-
Can you rephrase the question?
Is your statement really "We already have 800TB storage, and we want to know if it will cost more to buy an additional X TB storage or delete 8TB?"
Is the storage rented or is it managed locally?
"Savings..." generally implies a comparison between alternatives, and there are no stated alternatives.
-
Do you mean 800 TB as in 800 terabytes ( 819,200 gigabytes) or was that a typo and you really mean 800 GB?
-
For example:
Let's say I have 80 TB of storage and am using 75% of same on average. I Delete 8 TB of data. I'm saving the company $XX Annually because of the deletion.The claim here is $1Million Dollars, but I don't buy it.

1. Price Does Not Equal Cost
The total cost of acquisition (TCA) for storage is roughly only 20 percent of TCO. Just a few years ago, the
price of the hardware and software was a much higher portion of TCO, but price erosion has changed that.With a TB costing about $150-200, 8 TB would be $1200-$1600; times 5 for TCO would give $6000-$8000. Let's be generous and make it $10k, but $1M is a bit of a stretch. It gets worse, because you also have to calculate the cost of running out of space, which will often be $10k per incident, easily.

Yeah, I came up with $120K a year for 20 terabytes of storage (triple redundant RAID 5 NAS), including office rental, utilities, and $80K Salary for a dedicated administrator, including a 10% per annum growth factor. But, as the data storage would share facilities with other services, $120K is major overkill.

$80K in American money.
If you can import that and convert to € on a yearly basis, then yeah, you're pretty wealthy. If you live in the USA, then not so much. A friend of mine does about the same level job as I do, and makes over twice as much, numerically speaking, but between the two of us, I have the most buying power.
I suppose it could vary greatly from one area to the next. Cities are especially awful.

If I get $80k for just monitoring 120 TB, I have about 39 hours per week left to do side jobs. I think I can even do the monitoring remotely from my porch in the Caribean.

Ok, I guess we're in agreement that the $1 million a year savings figure uses some kind of "special" math.

That could also be "$80k budget for salary" which really comes to something like a salary of $53k; the other $27k are for payroll and other employment taxes and benefits (general rule of thumb I've heard is that cost of a person is roughly 1.5x their cash salary).

Unless you live in a WTF place like mine where you get paid in goods and services if anything at all. :(

You live in the past?

$1M is about what a decent 800TB SAN system will cost. Given the above estimate that cost of ownership is 5 times cost of acquisition, then the cost of ownership should be around $5M for 800TB. 8TB would account for $500K of the total. The estimate in the millions isn't that far off, but it does seem a bit high. Also, you really won't "save" that money unless the space can be used for something else.

Er... No. $50k.

Yes, I now understand that the original estimate was based on just picking a high number out of thin air.

HA! I actually got real world numbers! for $1 million a year I can get third party hosting for 180TB of data - with backup.
8 TB is around $45,000
So, my call of shenanigans stands!

Or they made a similar math error to the one I made. I was only off by 10% after the error was corrected.@Jaime said:
