nForce3-250Gb: 4-Drive SATA RAID and IDE RAID

Integrated RAID capabilities have become common with most of today's chipsets. Most competing chipsets provide the ability to use SATA RAID 0 (Striping) for Performance or RAID 1 (mirroring) for Data Protection. The nForce3-250 chipset takes these capabilities even further, however, with four drives instead of the two supported by other chipsets. These 4 drives can also be configured as RAID 0+1, which combines both striping and mirroring for speed and data protection.



RAID Level 0+1 Disk Striping and Mirroring


Cross-Controller RAID

The nVidia RAID solution is also unique in supporting both Serial ATA (SATA) and parallel ATA disk devices within a single RAID array. Users don't need to worry about whether hard drives are SATA or IDE - - the nVidia RAID controller treats both IDE and SATA drives the same and allows them to be combined in any way in the RAID controller. A single setup procedure applies to all drives, which makes it possible to use all the storage devices available. Users can also expand the number of drives easily without worrying about whether the drive is IDE or SATA.

On-the-Fly Rebuilds and Spare Disk Allocation

Corporate RAID users are accustomed to RAID arrays with "hot spares" and on-the fly rebuilds, but those RAID 5 features have been expensive additions to a home PC. The nVidia RAID controller adds both these features to a home PC that is running any type of mirroring. If a disk fails, RAID 1 allows continuous operation by taking advantage of the mirrored data copy in the array. The nVidia RAID solution goes a step further and lets a user rebuild a new mirrored copy for the data while the system is up and running, without disrupting user and application access to the data set. Rebuilding on the fly eliminates down time and maximizes protection for critical storage resources.

nVidia RAID 1 also lets users designate spare drives that can be configured as hot standbys, protecting arrays in the event of a disk failure. A shared spare can protect multiple arrays of drives, or a dedicated spare can serve as a hot standby for a particular drive array. The spare disk feature, which offers protection that goes beyond mirroring data, has traditionally been limited to high-end RAID systems. Truthfully, the RAID capabilities that nVidia has built into nForce3-250 will blow away almost any high-end home user. This isn't RAID 5 on a home PC, but the flexibility and data protection capabilities are truly impressive.

    #18, I know it's full duplex, but even then you will have a hard time getting full utlization under normal working conditions. Benchmarks are designed to run things at unrealistic rates. The point is, although I don't encourage it, you can certainly put Gigabit on the PCI bus and get very usable performance out of it. In most cases, the limiting factor is going to be CPU utilization anyway. Reply

    External HDDs could make good use of a Firewire connection, especially now it is whizzing along at 800MBit/s.

    The multi CPU implementation sounds interesting, of course AMD will completely fail to capitalise on it by not making the FX dual processor capable. How many enthusiasts (AMD wise) could resist the chance of dual FX-53s, especially with the possibility of overclocking them? You have the distinction between the 2xx series and the FX due the removal of ECC/Registered memory in the FX 939 series, so they essentially serve two different markets.

    Why would you need firewire with USB2? OK, ipod and camcorders.

    I have one question. Since you use a browser to configure the firewall, does this mean it is OS independant, i.e., I can use it in Linux without needing drivers to run it?
    Soundstorm not present on here, oh well, almost all uATX boards had the MCP and not MCP-T so it didn't matter anyhow, and it doesn't work in Linux anyhow. VIA sound is troublesome in Linux too. I rather use my own sound card. Just hope there is a driver for the cool LAN adapter.

    LAN is Duplex. Gigabit on PCI with overhead can do about 820mb/sec in industry standard tests. nVidia's on-chip LAN could output about 1840 mb/sec in the benchmarks we have seen. This is more than twice as fast IF you have a source that can actually output 1GB in both directions.

    PCI Express will be seen on Intel boards very soon. AMD boards will not move as rapidly to the Intel PCI Express standard.

    Firewire is not on-chip. Undoubtedly many mfgs will add firewire with an additional chip on-board nF3-250.

    ''No one can possibly complain about the feature-set of nForce3-250''

    to add my vote to what's already been said, no firewire for my iPod and no SoundStorm/DolbyDigital for that lovely Yamaha amp I just bought mean i think someone needs to calm down a little about all that excitement (and learn a little about the difference between megabits and bytes by the sound of things)

    i wonder if they'll release Soundstorm as a PCI eXpress card....

    #8: Actually, to date nVidia has had a *very* troublesome PCI implementation, anyone with a PCI RAID controller and a 4 disk RAID 0 array can tell you that. It is so bad, in fact, that prototype NF3-150 boards for Opteron used AMD PCI chips just to avoid using the nForce3 integrated PCI bus. I am not certain if these boards ever reached production status however.

    As for this chipset, it looks nice, but honestly I'll wait until there is a PCI Express solution out there, I was just forced due to power problems destroying my equipment to upgrade my motherboard prematurely, and I don't intend to buy another until the next wave of features is available...

    Keep your eyes open for my AN50R listing for sale at rock bottom pricing in the FS/FT forum when the 250 is on shelves :D Reply

    Looks like another error on the "Conclusion" page. Last sentence, second paragraph says "We expect that some enterprising companies, which specializes in catering to the computer enthusiast, will slip in some Socket 954 boards based on the Ultra chipset with a Gigahertz HyperTransport."

    Socket 954? Methinks that ought to be Socket 754.

    What about firewire connectors, do you guys think they'll be added to production boards? Reply
