Hi guys, I need a server to host remote videos surveillance, IP cameras, working under windows environment, I thought to install windows server 2012 R2 and do double parity with future multiple hard disks.

I want something that is scalable, and I'll start first with RAID 1, but the idea is to use a similar system to raid 6, but in software, since I'm from Venezuela, and buy 2 cards raid to support raid 6 are costly.

I've considered buying NORCO 4U 20 bays, for use for now 2 bays, but that i can upgrade only with the buy other hard drive.

What solution they would recommend to me?

Sorry for the english, and greetings from Venezuela :)

Hey there, risklife!

A similar to RAID 6 system is RAID 5, actually RAID 6 is an extended version of RAID 5.
I'd suggest to check out this array configuration for your surveillance video storage solution.
RAID 5 delivers the best overall balance of data protection and performance and makes the most efficient use of drive capacity of all RAID techniques. I did some research for you and found out that it is also the preferred choice when building DVR and IP storage systems.
This array requires three or more identical drives to be in a RAID group. Data is striped across drives, and parity is distributed amongst them all. It may not be as fast as RAID 1 because its parity data is spread across multiple drives, but data loss risks are...

Afterwards, it's going to be much easier for you to upgrade your configuration to RAID 6, though it is not recommended. Moreover, RAID 6 is not seen as the best storage solution for surveillance at all.
I'd suggest checking out these articles that might convince you:

Hope I was able to help!

Thanks for the information.

I like raid 6 because it protects me from the 2 failure of simultaneous hard drives, and is very important in a surveillance system with multiple disks.

I want use hard drive 2 or 4TB in the server.

I was thinking of using double parity windows server 2012 R2 with this function, but i dont know the performance I/O.

How could I connect 24 drives to the motherboard for use under windows, but without raid cards.

From your linked article: "This has been proven by us in our recording environment. In 2006, we replaced all of our servers and RAIDs. Our new RAIDs were set up, at our insistence, as RAID 6. Although we have experienced at least three instances where two drives failed in an enclosure, including at least two instances where the second drive failed during the rebuild process, we have never lost any data. The systems rebuilt both failed drives and continued to run flawlessly.
Conclusion
For these reasons, I would never recommend using RAID 5 in a critical video recording environment. The risks of data loss are too great."

Maybe i missed something but it seems like the article you linked kind of contradicts you. I am not trying to stir anything up, I actually came to this thread to learn about a possible build for a video surveillance system for my business. Any feedback would be most appreciated.
