Not quite. Im given budget. So, you have x to do y.
Also if your boss gave you a budget, then they must know that the budget will not meet the business needs and that somewhere corners are going to be cut.
Warranty, part quality, storage capacity, reliability.
Something has to give to reduce the cost, and the most likely thing to be cut (easily) is the warranty.
Exactly...
- If he came up with the budget, tell him to tell you what to buy with it. He can't have produced a budget without knowing what that budget would buy. So he knows something you don't.
- What the business wants here isn't within its reach. Something HAS to give. And the one thing that makes zero sense to give is "the ability to be the desired solution."
-
Now for the REAL question....
What the heck is the goal? All of this is under the hood discussion. At no point has anyone said "here is the end goal". Instead, we are given a stack of money, and a set of technologies and specs, and told to make the two meet. That is never how to approach an IT (or any) problem. Chances are, a bunch of false assumptions are included here and are causing a lot of the problems.
Bottom line... what's being asked for cannot be done in any acceptable fashion, not even close. But what we assume the goal is can probably be met pretty easily. We just have to know for sure what the goal actually is, so that we can ensure that we meet it.

The issue is due to the capacity you're looking at, unless you were going with those 18TB SSD Samsung drives, which at that capacity you'd consider RAID6.
It's 7.2k disks, only for backups.
In something like RAID 6, imagine the time it would take to resilver even a single drive. That make drives, that slow, at that size... it could take 2-3 months easily to replace a single failed drive!
Um no... it would take way longer. It took a 12 TB (total) RAID 5 a month and a half. It was successful, but omg no way for RAID 6 and especially not at that size.
-
The reality is, this is just unfeasible. Without a vendor giving hardware away (and providing an extended warranty) would this budget work.
And that's for any give component. The chassis, the drives, the MB (CPU and RAM)
-
@scottalanmiller the goal, at least described ever so briefly is for backup storage. (presumably if the production file server(s) take a dive). Those could be OBR5 for all we know.
Why is cloud backup not an option (besides because the boss said so)?

Because that many TB cloud storage is crazy expensive for an SMB. A lot of places give free storage for archive and such, but 100+ TB of actual usage would be insane cost wise. On-prem is way cheaper, tape is also way cheaper. At that size I'd only consider Wasabi, and even at 150TB, that's $30K per year.

Or the BIG question, why are disks being considered when tape is the logical or obvious "go to" for backups. Why did tapes get ruled out or skipped over?

Only about $12K. Still a lot, but not AS bad.

Um. . . crazy expensive to compared to having your 1 and only working backup system die when you need it and then the business is done for?
At B2 the price is pretty flipping cheap per month.

My bad, forgot to move the slider.

How expensive would it be for the down time required to download that much damn data? Or wait to have it shipped if they do that?

If going down that path... how much will it cost when the QNAP doesn't work to restore the data at all

Anyone got a quick number of what LTO would cost for this?

That was my next thought!

I htink 5 LTO 6 would be like $30 or something like that, which is like 12TB.

Who says you need to download the entire thing? And in the worst case B2 (edit any cloud storage provider) will ship you a drive with all of your data that you'd just plug in and pull off of directly into your file share.

You said that when you said the production filer server(s) take a dive. That implies the whole lot.

Quick numbers...
HPE StoreEver LTO-7 Drive is $3,650.

Fair enough, but at the same time a production server taking a dive (depending on how the environment is setup) could be hosting iscsi shares into a hypervisor with a small-medium share of rarely-occasionally used data.
