Putting my WHS box in the cloud would be the only way around that it seems - something like a farm of those BackBlaze boxes that we rent/buy space on and stream our TV, movies, pictures, etc. from. I'm not excited about lack of physical ownership, but I wonder if that's the future.
For the moment, I think better off site backup, would be to build a badass box and ship it to Ockie's data center (with backup data on it and sync it it up to date daily from there on out.)
[LYL]Homer;1034567069 said:Ockie probably wouldn't want to deal with 43 different case types. However, what if he built the box (something akin to the BackBlaze) and shipped it to you with semi-automated software (or a wizard) that would backup a WHS. Then it would be shipped back to him to be installed in his datacenter and be all standardized and pretty.
I have been thinking of a way to do this but hardware raid and I figured out if someone used that case with a Corsair 1kw psu, an Areca 1680ix-24 and the HP Sas Expander card, mobo with onboard video and 2x pci-e slots, any cpu, whatever ram and custom made backplanes with sata and power. They could have a nice cheap hardware raid version for a bit under $10k.
What do you mean you won't need the 1680? For hardware raid you could use the arc1680ix-24 connected to the HP Sas expander via an external SFF-8088 cable for a total of 48 Sata ports. I also just emailed the CEO of backblaze asking where it would be possible to buy some of the pod cases. If you used 2TB drives the price would go up quite a bit but then you could have 900TB advertised capacity in one 42u rack.
Mozy Home is $4.95 a month for unlimited backup. Is there any reason to go with this instead?
mozy seems to have no file size limit but the home version doesn't support network shares you nee pro account for which they charge $0.50 per GB
omg, it's using a PCI SATA-II card with four ports... um, ok. That's going to bottleneck all to hell.
The PCI-E ones will be fine with the port bandwidth, but just PCI?!?! One SATA-II port is 300MB/s and let's say these drives cap at 80MB/S for full load. PCI only has 133MB/s port bandwidth (for all ports combined). So just 2 drives would bottleneck the card.
I get the point of the card itself as a low-end solution, just to get connectivity with the drives, but for $7,800+, that's pretty lame.
Also, the card itself is not hardware RAID, so that's another minus!
If the mobo is limiting it b/c of the lack of ports, it's time to change up the mobo for one that has enough PCI-E slots.
Lets do some math shall we. They have 3 x 15 drive RAID 6 arrays. Since it is software RAID, we are limited by the throughput of the drive controllers (specifically the PCI bus) for a rebuild. Now if we figure out how long it takes to do a rebuild with the best case scenario, you can see how ghetto their setup is. Rebuilding 19.5tb at 133mb/s would take a minimum of 41 hours if we weren't say CPU limited. That means that the array is offline and the other two arrays are not being accessed...not an option for an enterprise environment (which is what they seem to be touting). So, lets divide that by 3 now since we have 3 arrays. With two arrays being accessed at 44mb/s and the last being rebuilt at that speed, we are now at 123 hours for a rebuild. Once again, since this array is still supposed to be usable (who does an offline rebuild anyway?), so we'll divide the rebuild speed by 2 (so, that the array is still usable). We're now at 244 hours (over 10 days) to rebuild the RAID array with a single disk failure if we aren't CPU limited in a perfect scenario. With multiple drive failures or other complications, it just gets worse. Now you see why I think it's a joke (and the fact that it probably can't even saturate a gigabit ethernet connection). Nice concept, but horrible implementation. I see it as a Ferrari body with a Yugo engine inside...
Still going to take forever. I don't think downtime would be acceptable for something of this scale to be honest.I have the feeling that they don't care about rebuilds, if the system drive fails, they will take the entire unit, replace the drive and recreate the entire array and post it back into the system as a clean array pod.

Oh, I was thinking this was a standalone solution...still not my cup of tea.Nono, this is why they are using this distributed cloud. Everything is replicated and self healing.
Buy two of these 4U boxes and Raid 1 em..
but the norco route makes more logical sense IMO.

I've been thinking about that, but I don't think that they would go for that... seriously. If I wanted to come and backup 30tb of data, I think they would have an issue with it... thats me consuming half of that machine or 4k worth in hardware... not to mention, I'm tied to a multi gig internet connection, so I'll be able to saturate a good portion of their bandwidth.
I just don't see how they make money. The only guess is that they hope people only upload 5-100gigs worth of stuff.
Either way, give it a try and let us know, if they don't complain, then I might consider that because it's cheaper than me buying hardware.

I already did the math, the norco route is still much cheaper. I contacted the company for the case and you are looking at about $800 in just the case plus who knows how much shipping.... by the time you add expanders and fans, you could have already bought three norcos.
Obviously you wont get the same density, but the norco route makes more logical sense IMO.
We won't mention how many other dozen plus ways these boxes fail basic reliability testing and requirements.
$800 for that case? Ouch... I was wondering how much they would charge for something like that...
I wonder how many I would need to buy for a bulk discount?
I wouldn't mind seeing a [H]ardforum users design a storage case... make it a competition or just a survey thing... Take input from users and design something that's easy to use with features that users want. So it'll have the nice big silent fans, adequate airflow, proper drive support, etc...
Maybe something to rival the Norco case? For comparisons sake, it should probably be cost equivalent to the Norco case and hold at least 20 drives...
Wonder who else makes cases...
