Netgear Introduces Linux-Based NAS Devices
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."
I hope this means sftp and https -- insecure WebDAV and FTP over the public Internet is one thing we do NOT need. Or maybe they should include a VPN server since some OS's don't have good support for WebDAV over HTTPs (XP tsk tsk).
-b.
I wondered about the article myself and checked how it had done on the firehose. It made it to red. Other articles on the main page only made it to orange. If you go by that, you would conclude that our fellow /. readers think this story is really newsworthy.
A more sinister interpretation might be that someone has found a way to game the firehose.
I agree with the other posters. This device doesn't seem that newsworthy. A quick check of my favorite online retailer shows that there are many such devices on the market.
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.
Good grief, can someone please explain to me what the fetish is with four drives in every single freakin NAS system on the planet? And every vendor gets the same thrill annoucing it as a "4TB" solution when only a complete moron would run these things as a single JBOD volume without any fault tolerance.
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).
Why not an even eight? How about a eSATA port so you could connect two NAS units together for expansion or redundancy? How about something like iSCSI and then let me chain as many NAS units together on a gigabit switch as I want?
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.
But it's ugly as sin. It's a cheap Dell server ($329 w 3yr warranty!) whose only purpose in life is to house the SAS card connected to this ugly black metal monolith with two very tacky plastic drive enclosure racks. I don't mind sticking it in the closet of my house but I really can't stand the idea of trying to sell something like this to anyone.
But until I can pop down to Best Buy and buy something that looks decent, or is modular or stackable, I guess I'm stuck with whatever FrankenRAID I can piece together.
Eight drives, guys, how 'bout it?

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.
"Supporting" is a wonderfully vague word.
We bought a 1TB NAS (can't remember the model) that 'supported' NFS. We had it connected to our server via ethernet, and mounted it using NFS. Ooh look, I copied a file. Ooh goody, I copied it back. Now let's copy half a terabyte of our backups onto the NAS...
Wakey wakey. Hello? Anyone in there? Oh dear it seems to have stopped after 200 megs. Try again. Pretty much the same...
We upgraded the NAS box to the latest OS, we asked the supplier who was no help. I even hacked root on the box in order to see the log files to find out what was going on. But my conclusion was that the system was built down to a price that wasn't capable of supporting some real NFS thrashing, and that they hadn't tested it. We sent it back.
These are probably fine for simple home use, but don't hammer them...
