Netgear Introduces Linux-Based NAS Devices 128

Posted by kdawson from the backup-and-archive-with-daring-and-whimsy dept.
drewmoney writes "A LinuxDevices.com article introduces several of Netgear's Linux-based NAS devices, technology they acquired with the purchase of Infrant earlier this year. (Here is Netgear's product page.) There are models from 1.5 TB, at about $1,100, to 4 TB, topped by a 4-TB rack-mount version. They are geared towards the professional home user and small and medium businesses. The NAS devices come complete with the usual RAID features, file-system access, and a built in USB print server. All are controlled through a Web GUI and some even offer SSH access."

        Sorry, no, they don't have a workable NFS solution, despite what the sales blurb claims. NFS without basic features like famd and posix attributes would be about as useful as Windows 3.11 would be for sharing SMB -- useful only for a single user environment where users don't take advantage of built-in features like setting permissions on network files or do naughty things like accessing the same file at the same time. In other words, slightly less useful than nothing for a business environment.

        I own a DNS-323 too. I loaded it up with two 500gb hard disks. It sucks. I still use it, but it sucks. The standard firmware only lets you update the device with D-Link digitally signed firmware. The D-Link firmware is buggy as hell, still, even after the thing has been out commercially for over a year.

        - It has a bad version of Samba on it that will cause your files to magically disappear if you decide to copy files larger than about 20 gigs, or if you copy large numbers of files at the same time.
        - It uses the ext2 filesystem, which not only lacks journalling, but has no nice way to fun fsck (only option is to enable telnet via a fun_plug and run fsck on your mounted filesystem...blech!).
        - It *still* has piss-poor unicode support.
        - The current firmware does funny things if one of your drives dies and you have a RAID-1 array, such as not rebuilding the array. Some users have reported that it won't even detect a drive failure in raid-1.
        - Its user/group and volume management simply doesn't work. You can't set up multiple shares and give different users different permissions to the shares. User/group management is a mess.

        All of these problems exist in the 1.03 firmware, which is the latest version. My unit has also been blessed with a common hardware problem -- one of the "drive okay" blue led's died. Quite a few folks are reporting this (probably cheap leds).

        About the only way to make the 323 usable and safe is to solder a serial port on it so that you can use redboot and overwrite the stock firmware. IMHO, if you're going to take the trouble to solder and manage the thing via the command-line, you may as well just plunk down a bit of extra cash and have an actual warranty. Or save the money and put two hard drives in an old computer/install linux distro of your choice. It certainly shouldn't be considered a reliable nas, and I certainly wouldn't be saving copies of anything important on it (unless you're backing the data up somewhere else).

    Why not five drives, guys? It's not like we are back in the late 90s when every motherboard had two IDE controllers supporting two devices. I routinely see motherboards now with five or six SATA ports. There are even splitters and repeaters that can change one SATA port into two. So why not break out and distinguish yourselfs with five drives so I can actually get a 4TB (3.8 actual *sigh*) solution AND a spare drive for the RAID set or even hotspare (if i'm feeling nervous).

    I finally had to stop buying NAS units and get my hands dirty and build my own so I could actually break the REAL 3TB ceiling. I went with a SAS RAID card and an enclosure that supports 8 SATA drives out of the box. Down the road, I can get a SAS repeater and add a second 8-drive enclosure, or a third, or a fourth. Online volume expansion folds new drives in like butter.

      If your client is seeing 50-60 Mbps writes and 100 Mbps reads, something is wrong. I've got one of these boxes at home and see over 200 Mbps in each direction. Check that configuration, update the firmware, do something.

    Netgear hasn't "introduced" anything. They are just re-branding the Infrant ReadyNAS products that have been on the market for at least a couple of years already. I'm not aware of any actual changes they've made to the devices themselves, so handing them complete credit for this is ridiculous.

    The ReadyNAS NV+ is a pretty interesting unit, by the way. I have been looking at it a lot lately. It's one of only a handful of midrange consumer NAS devices that include features like Gigabit ethernet (so it's not slow as molasses) and support for not only SMB/CIFS and FTP but also the native Mac file sharing protocol, AFS 3.1. (Yes I'm perfectly aware that Mac OS X has no problem with SMB/CIFS, but it's a more pleasant experience to connect with AFS, and it also works with the Classic Mac OS. Believe it or not, some people do still use Mac OS 8/9 for various reasons.)

    The ReadyNAS can be configured in several different disk modes from JBOD to RAID 0, 0+1, 5, to some proprietary mode Infrant calls X-RAID which supposedly uses disk space more efficiently than RAID 5 (when you're using 3 or 4 drives). The last big positive I can think of at the moment is that it actually supports a list of UPSes so your home or office file/backup server will theoretically shut itself down safely rather than crashing hard when the UPS battery runs down after the power has been off for an hour in the middle of the night. How about that.

    Unfortunately the ReadyNAS, like all the other NAS (and non-NAS) multi-drive RAID-type storage devices fails to impress me in one regard. The hardware itself that controls the drives is still a scary single point of failure. I may be protecting myself from a drive failure, but if the hardware fails you lose everything anyway! The chances of the important hardware failing is always greater than zero, and the probability that you will somehow be able to recover your data by sticking the drives into another identical device is much, much lower than 100%. So to be reasonably sure that you won't lose your entire array you need to get at least TWO of these expensive devices and keep them synchronized. This is tantamount to failure in my book.

    So in the end I have kind of written off all these devices and I'm waiting for widespread ZFS support in Linux, Mac OS X, FreeBSD, et al. It's coming soon (except for Windows, I don't hold out much hope for Windows ZFS support, third-party or otherwise). When that happens it will be possible to take some generic PC hardware and create a ZFS raidz2 array that can handle losing two drives without failing to protect the data, then if that PC hardware fails you can take that ZFS raidz2 array and hook it up to some other generic PC hardware and simply do a "zpool import" and go on about your business. No insanity like losing an entire RAID array because of some stupid little glitch in the RAID hardware. Eff-you-see-kay THAT, buddy.

    Unless I am completely misunderstanding the capabilities of ZFS and raidz/raidz2, it would seem that we are currently on the threshold of the first and only truly resilient data storage method that won't cost a king's ransom to implement. Any supported generic PC hardware (cheap) with Gigabit ethernet, SATA and at least 1GB of RAM will be able to become a file server that will outstrip by a country mile the performance and reliability of all these regular RAID-based NAS devices that almost across the board have abysmal data transfer speeds. Even the very nice Netgear/Infrant ReadyNAS NV+ will be completely obsolete unless they jump on the ZFS bandwagon.

    Mark my words. The entire data storage industry will be changing very soon. Most folks here don't seem to see it yet but I think ZFS is going to be big. Like, iPod big, or iPhone big. Everybody scoffed at those devices at first. Well, they aren't scoffing now. I think widespread ZFS support is going to do the same sort of thing. It seems like just another filesystem at first, but it ain't.
    • I have to agree , playing with ZFS at Sun was really quite interesting , seeing what can be done and still be recoverable made me quite honestly take note of the abilities of the file system.

      ZFS is going to make quite a big impact , and Microsoft will have to take note and build in support, most big business will be swapping to ZFS and since that is where Microsoft's bread and butter is coming from they will have to add support for it sooner or later. With it's list of features it will have a home on the Mi
    • I'm educated and experienced enough to easily build my own NAS (and a large variety other things), but I have far more valuable ways to use that time (my research). So I bought two of the 4-750GB versions with 1GB of RAM. They are very compact, attractive, and are overall satisfactory to me.

        This is a reply both to you and the AC above (who was being quite a jackass in his response). I might point out that I never said the ReadyNAS was a particularly bad choice, especially if you need a large amount of networkable storage right now. It's a great device, according to the reviews. It just doesn't meet my personal expectations for a device that's supposed to reliably keep data safe without ever failing in a way that would destroy data.

        Good on you both for buying the product if you need it. However
  • I recently threw two SATA drives into an old Shuttle PC I had laying around and installed FreeNAS on a 128MB CompactFlash card. So far I'm quite impressed. And while I'm running it strictly as a JBOD right now, it has the capability for (software) RAID levels 0-5. I haven't delved into it too much, but it may support some hardware RAID cards. Can't beat it if you have an old PC laying about.

      It's easy to beat. People often forget about the power usage of a PC. That thing is bleeding 100 to 300 watts and that probably makes the Netgear equipment much cheaper.

      • I think you need one of these [clubit.com] to install in that old beige box or if you crave a complete solution, one of these [zareason.com].

        And let's not forget openfiler [openfiler.com], since we're mentioning free NAS solutions. It's not lightweight, but it looks pretty cool.

        • Thanks for the links. I really like the Via. Just like you said, it could be a drop-in replacement for that beige box.

        I doubt even fullblown gaming rigs draws 300W at idle unless you got a hefty SLI setup. Above and beyond the disks which the NAS has to power too, it's basicly CPU+GPU+mobo. Make that integrated graphics and the GPU goes away. The hardware came "free" in that it's used components with low resale value. Of course, if you don't plan to take advantage of anything else than as a file server it might be a close call, if you're slightly more advanced it's a no-brainer in my opinion.
  • http://www.freenas.org/ [freenas.org] - FreeBSD based, a pleasure to install, configure and use.
    • See also OpenFiler [openfiler.com] for another option. Linux based, has a slightly different feature set. Supports snapshots, ldap and kerberos auth, which FreeNAS seems to be missing at this time (unless I missed something or the wiki is outdated). Doubtless missing a few things FreeNAS has; e.g. AFS.
  • Take a look at the Thecus N2100. For $360 or less it appears to have similar capabilities.

  • Having Linux etc. in a NAS is nice - but the features ZFS offers (almost no-cost snapshots, clones, RAID-levels, volume-expansion etc.pp - see the various articles on Wikipedia, OpenSolaris, Sun.com and solarisinternals, if you have been living under a rock for the past years) will *kill* every other filesystem (or push it back into a niche).
    It might also kill NetApp at the same time.
    OpenSolaris even has an iSCSI-Target.
    Yes, it needs a lot of RAM and a 64 Bit CPU to be useful - but in return, you get what w
  • Nice try Netgear, this company http://www.qnap.com/ [qnap.com] already has some of the fastest Linux ARM based routers on the market. Tom's hardware recently reviewed their TS-209 Pro series which ranked as one of the fastest NAS's they've ever used. It also supports a huge variety of OSs and is probably closer to a micro server than a NAS.
  • I thought Linux was supposed to be "free".... but the units they're talking about cost as much as any other with an embedded proprietary OS.

    At least with Linux you could hack together a network connected lump of 1.5TB for less than $1100 on your own.
