    Need help with RAID solution

    Cool I'll check them out And I see why you didn't bother mentioning them I wouldn't even be able to get a quote on price without representing a company. Oh well. Their loss.

    I'd be curious what your recommendations would be among the cards you have tested. I don't necessarily need to go with low cost, unless all else is equal

    I see. Thanks for the clarification. Not sure why I didn't see that. I went down the list looking for something like that (some kind of fan-out cable) and thought I only saw 1:1's. My mistake. Would you recommend any particular brand for RAID controllers? I'm looking for a 12-port but of course if there are more, that is ok since I don't need to use them all. I've seen a lot from Norco and San Digital that looked good (price per port)-wise. But I have no experience with them

    I'm talking about a RAID controller though. Not an HBA card. HBA just effectively expands the # of SATA slots on your mobo right? Beginning to think there is some conspiracy on the internet to avoid answering this question. I've asked in so many forums and fired off so many emails and read so much and I just cannot find an answer to the question of how you plug HDD's into the RAID controller. I know I'm overlooking something but at this point, considering how many times I've asked that specific question in this thread and no one seems willing to answer.. I'm going to guess maybe.. no one knows? -.-

    How do I hook the HDD's to the RAID controller?

    I scoured those links but I still don't understand what connects the HDD's to the RAID controller. It only shows two SAS ports and all the cables are 1:1. So I just don't understand: What connects all the drives to the controller? I assumed the RAID controller would have 8 SATA ports. But it has two SAS ports. I'm really confused about this Is it that the drives need to be directly connected to the motherboard? If so what's the point of these SAS ports on the RAID controller anyway? I'm beginning to question whether a 12-drive RAID is possible without using an enclosure. Or am I supposed to use some cable that fans out one SAS port to multiple SATA ports? I just want to do what's most standard here and not find some awkward workaround.

    Does anyone know this? It's one of the major issues holding me back from pulling the trigger on these purchases

    Well what I'm wondering is, say I found a tower that could house the cards, and I had a RAID controller plugged into the mobo inside. How would I hook the drives up to the RAID card? Do RAID cards have tons of ports? Or is there some other device I'd need to use into which I'd plug all the disks, that then connects to the RAID card via a SAS cable? Performance requirement: should be able to pump 100 megs/second. That's plenty to have half a dozen (at most) people streaming compressed bluray content (that's in the neighborhood of 10 gigs tops per 7200'ish seconds which is only 1.5 MB/second) or mounting ISO's off of it or whatever. And reasonable for writes as well. And fast enough for rebuilds to not take forever in case of drive failure. I'm pretty confident that with 12 drives in any RAID config, I'm going to be able to get that bare minimum 100 megs/second, so I'm not worried about performance at all. Fault tolerance requirement: I was considering doing a RAID 60 with two six-drive layers so it could absorb 4 disk failures as long as no more than two were from a given layer. But I believe RAID 6 will be sufficient, since it takes me from 2/3 space utilization to 5/6 and I'll have spare drives handy to deal with failures. So what I know I want is: 12x4TB drives in a RAID 6 configuration. What I'm still trying to decide is: what type of enclosure/NAS/computer-with-really-big-tower-that-can-house-many-drives/RAID-card/etc. do I want. So far enclosure seems to be the single most expensive component (all drives together being more expensive of course) and I figured maybe there's no real need for an enclosure as long as I've got a big tower that can house 12 drives all hooked up to a RAID card somehow. Just wondering how exactly they hook up or if I'm misunderstanding how RAID enclosures work. Having used the Mediasonic which handles everything, including RAID, means I've never had to actually construct a RAID array by hand before.

    Budget isn't really an issue. I have a few people going in on it with me. So I'm just curious what the options are for a 12-bay RAID 6 enclosure of 4 TB drives. I'm seeing stuff from NORCO, SANS DIGITAL, and others. Trying to figure out if I should buy one of these $1k+ enclosures and an expensive RAID card and hook the whole thing up to my PC (or a new cheap PC) via a SAS cable. -or- If it would be possible to avoid a ton of that cost by just building a cheap computer in a huge tower that can house 12 (or 13, including boot) drives and just hook them all up to an internal RAID card. (is this possible?) If that second option is recommended, how exactly would it work? What do all the hard drives plug into? Is there some extra device I'd need to buy to plug all the hard drives into that would then connect to the RAID card via a SAS cable? You can see my head is swimming with all the options here. Limited knowledge of all this stuff doesn't help much either
  10. I need a 12 (at least) drive RAID solution. Up till now I've been using Mediasonic's 8-bay RAID enclosure with 8 Seagate 3 TB's in a RAID 50 setup. This gives 18 TB of space (16.3 TiB) It's currently down to 10% available space so it's time to get something bigger. I'd like to setup something like a 12-drive RAID 6 with 4 TB drives. As much as I look I can't find a 12-drive RAID enclosure that isn't ten times the cost of Mediasonic's great 8-drive RAID enclosure. I can't find any reliable RAID cards for building my own NAS. Does anyone have any recommendations? RAID 6 provides the fault tolerance I need. 4 TB drives provide the capacity I need. It only needs to be able to stream bluray content and occasionally mount ISO's from it. I don't think any solution is going to fall short of being able to stream compressed bluray content to 2 or 3 peers simultaneously.
