Hardware Design for SAM-DR Small Rackmount Backup Device
-
Of course a 1U rackmount solution will not directly compete with an SMB NAS device on cost, as those will come in desktop form factors that are very inexpensive. This adds benefits like hardware RAID, NV Write cache acceleration, hot swap power supplies, NBD parts (including drives), SAS drvies, more GigE ports, bigger processor, "on appliance" backup utilities (not included in this direct discussion), etc.
Also of important note is that with the right software, this model will be scale out design, adding a lot of flexibility to start with one and grow with another when the time comes, instead of a forklift upgrade.

How an e3 impact on cost. Less core higher freq. More cheap?
-
@scottalanmiller Is there much performance difference between SATA and SAS? Or is it marginal so for the same money SAS just makes a bit more sense?

Nope, for many of the drives they were literally the same!

E5 is the lowest we could get in this scenario.

I'll stick with SATA then, easier to get replacements.

Up to 20% drop in performance. Is it REALLY easier to get replacements? At least in the US it is very much the opposite. SATA is much less common because no one buys them, so they practically don't exist. For exactly the reason you mention, we'd not put SATA in servers.

!?!?! I just asked you that below and you said there wasn't much difference! lol
I will consider SAS then.
SATA is much easier to get replacements (for us) because we don't deal with any large IT vendors, almost ever.

I thought you were asking about price. They are the same price, but no one buys SATA because they are the same price. The SCSI protocol is vastly more efficient than the ATA protocol.

But in this example of the Dell parts, only Dell drives work reliably, so dealing with big vendors for SAS drives is the best option as SATA drives that aren't tested specifically easily won't work.
-
There's no talk of vendor here so I'll just ask
Would these come from XByte? -
Now if you do your own testing and know ahead of time that WD RE generic drives will work just fine, then that's different. However, WD RE SAS is likely easier to get than WD RE SATA for the same reasons.

In the US at least. @MattSpeller is in Canada, so while he can do that, the benefits are not the same. -

I wish Xbyte had Canadian distributors. Other than the exchange rate (which right now is a killer), I found that often, suppliers in the US don't know that shipping servers or parts to Canada is supposed to be customs exempt (no additional duties other than the HST tax). That's bit me more than once.

No kidding, that would make so many things so much easier.

Well, YOU say that it is exempt. But Canada doesn't agree with you. I can tell you that they demand customs at the border and saying that it is not required isn't really something that you get to decide at that time. They might tell citizens that it is exempt, but they are lying to you.

No, actually, the tarif is 0 (at least to Ontario it is). Encourage you to have a read...

Look for section 8471.41
When paperwork properly completed (and this is where the failure happens most often - no lying needed), I've purchased goods from the US on dozens of occasions with zero tarif. Only paid HST.
