Why Choose AetherStore Over a NAS?

If you have a 500GB hard drive, with 300GB free, it realistically can only store 300GB of data?
Yes, a drive with only 300GB free can only store 300GB of data. That's not really an AetherStore question

Awesome post @shannon thanks for giving us the lay of the land.

Thanks @shannon

Speed: AetherStore is a robust, affordable and secure backup target that provides quick enough read times to serve its intended purpose well – reducing downtime, helping you meet RTO when the crunch is on.
Go on then, tell us the figures

Lots of factors there, I'm sure. The biggest question would be, I supposed, how fast would AetherStore be if only it were the bottleneck.

Mount store, run read/write speed test.
Really easy to do.

No, that would be a test of the hardware, not of AetherStore. That's not how you test software.

LOL - AetherStore on 1 PC with only SSD will crush a small network of HDDs of AetherStore. So any numbers you get would be meaningless. You have to test it in your own environment.
Basically what I want to hear is that users (other IT Pros) think it's usably fast. JB reported the V1 was not.

I assume that disk speed, RAM and network all play a bit of a role.

No...You'd do the exact same test whether its SDN or hardware based storage.
If you are measuring heat in a room, you don't care what the heating system is, you are only measuring the result.
What is the read write speeds of AetherStore on the mount point, a very measurable and provable figure.
The only reason I've not done it yet is because the test lab is being moved.

Pile of rubbish.
You post the stats of your environment with the test.
The test I did with AetherStore was on all SSD storage last year, the bottle-neck was very much the software with a write of 8 and a read of 20.

@scottalanmiller Really, how does ever node contain all of the data?
If you have RAID 1 on four drives, each drive contains all of the data. You have to lose all four drives to lose anything.
This isn't RAID 1, but it is RAIN acting like RAID 1 with four time mirroring in a case of four nodes with the stock four times replication.
The RAIN aspect of the storage distribution definitely makes locating and killing all 4 nodes difficult in a larger node array. Of course in a small 4 drive array, well, it's downright easy, and Scott's comment about all of them is right - 4 devices, 4 copies, means all data has to be on all 4 devices.
@DustinB3403 said in Why Choose AetherStore Over a NAS?:
@shannon This is a generic question that could vary a lot with the answer.
How many nodes would have to be lost to be unable to restore?
I know I know, its a very generic question.
In a four copy distribution, you would have to loose 4 nodes before the array would be offline. The four nodes that contain the same bits of data.
Due to RAIN, not all of the same data would be lost/unavailable by those 4 nodes going offline (for data integrity, I hope that the array takes itself offline). There might only be one blob of data shared by these 4 nodes, but that one blob, if it works that way I think it does, that one blob will take the entire array offline because now you don't have access the entire data set. -

Sure, but your performance would still crush someone who is doing that same test on HDD.

Would it now? Or would it be identical because the hardware is not the bottleneck, it's the SDN tool.
But we'll have no flipping clue if nobody tests the product. I can't believe this is not already covered.

Not due to RAIN but only due to spreading redundancy out over more nodes. This is something that you control. You can always force the system into full copies on every node.

Of course you can - you do that by upping the number of copies to match the number of machines in the pool. (or do they have some other kind of setting for that?)
I also think I see my error in saying due to RAIN, Yeah, you're right RAIN might just coincidentally put all the same data on those 4 nodes, then again might not. Thanks.

It's the same setting no matter how you display it.

Nice writeup @shannon
