Would you still recommend a higher end model if this is all I will be using it for? If you're not streaming hi-def content then you'd be fine. I would go with something a little better if you are streaming hi-def though. Really, the N40L is your best option for cost. Synology are great boxes and easy to setup, but to get decent speeds you need the non "j" version. I use mine for backups only so I've never used it as a upnp server. FreeNAS is coming out with a upnp server in 8.2 and in addition, you can install PS3 media server (not just for the PS3) on the current release. Unrelated, has anyone had success in setting up SSH keys for FreeNAS using puttygen? I'm copying the openssh key but FreeNAS keeps refusing my keys. I know they work because I'm using the same key pair with my Synology box. I've tried making the keys on both puttygen and using ssh-keygen on the server. Edit: I fixed my SSH keys issue. It was directory permissions causing it. I did a "tail /var/log/auth.log and saw this: "Apr 5 15:06:13 luna sshd[8524]: Authentication refused: bad ownership or modes for directory /mnt/data/homes/ryan" the ownership was root:wheel which I changed to ryan:wheel and it worked.

Roving Reporter posted:After reading the past 10+ pages, I'm looking towards a N40L once another sale pops up. The $180/190/200 prices are too good, especially since I already have 2 x 4TB drives. Then, roll that saving into another 2TB drive or i3 HTPC to transcode/stream/SABnzbd/etc. So, far my OS prospects are WHS2011 with either Flexnas/DriveBender/DrivePool. I have WHS 2011 and Drivepool. Everything works perfectly fine, and the UI is pretty nice even if I hardly use it. I added some disks and its dead simple. I would say if you want to run a windows-based setup you can't go wrong with WHS 2011 (which is currently on sale at newegg for $43 or so I think) and one of the drive pooling addons. I can't really come up with any negatives. Is there a recommended external esata enclosure thats not stupid expensive to go along with the n40l? My homebuilt machine I am tiring of, fairly loud and overkill for what I use my server for.

Guys I've gone ahead and bought myself a bunch of kit for a ZFS build and it's all hosed. That is to say, I get transfer speeds over CIFS of like 10kb/s. zpool commands take a long rear end time to run. What the hell is going on here? Hardware: Intel 2700k Asrock Extreme4 Gen3 mb 16gb RAM 10*2tb disks of varying manufacturers 1 addonics port multiplier I've installed ESXi 5.0 on a thumbdrive, and created a VM to run the storage. I've mapped the drives through to the VM as RDMs. I've tried FreeNAS but it's slow as gently caress to do anything - often the webgui will just time out. Once a zpool is created, the web gui will often even fail to load properly anymore. Tried OpenIndiana and napp-it, zpool creates are super slow, and writing to the shares is super slow. What am I missing here?? I'm super pissed off, feel like I've wasted a stack of cash.

Have you tried it without using ESXi? ESXi should work but I would try to keep things as simple as possible (FreeNAS straight on the thumb drive) to verify it's functioning and then build up from there.

The thing that sticks out of me about that hardware is the port multiplier. You'd be much better off getting a SAS card like the IBM M1015 to drive those drives.

You know, thanks for saying the boot from USB thing. I've plainly just been blinded by rage at this poo poo not working while I can see in reports that it works for basically EVERYBODY ELSE so after trying to boot from USB with OpenIndiana and that failing I threw in the towel on that front and didn't revisit it. I have real anger issues when it comes to spending money. :S So I've just tried FreeNAS and that has given me hope, I can get ~20mb/s write speeds now and the expected 100mb/s read speeds. The port multiplier, I hear ya, but this isn't for high bandwidth requirements this box. Yes, I need better than 20mb/s, but I don't think that's down to the port multiplier. There are only 3 drives attached to that PM at the moment, so at worst, the whole array is down to 1/3rd the performance of a SATAII port, and a single drive can't even max out a SATAII port anyway. But, I do appreciate the input, and if I can't get any better write performance fairly soon, I will remove the PM, create a zpool with 8 drives instead of 10 and see how that goes performance wise. If it's not already obvious, I have the PM because I have 10 drives for the zpool, and this motherboard only has 8 SATA ports. Further, I don't want to spend a fair bit of cash on a "real" RAID card which I will not be using any hardware RAID features, and I've read reports that some RAID cards actually increase disk latency even when just in pass-through mode. Edit: Speaking of, does anyone have any suggestions on troubleshooting commands I should be running, or steps I can try to use to increase my write speed, via CIFS?

If you only need 2 more ports, a 2 port SATA card is like $30. The problem with the multiplier is driver support, which could be causing your problems. Whenever I looked into it I couldn't find anything that said they would work in any form in Solaris. Making an 8 drive pool is a good test (this is RAIDZ2, right? Don't do RAIDZ1). You can also try and eliminate the networking. Do a dd from /dev/random to the pool to test write speeds, and a dd from the pool to /dev/null to test read speeds.

I think I've ruled out network: dd write: 28556104 bytes / sec (28MB/s) dd read: 82035806 bytes / sec (82MB/s) The dd read is slower than what my CIFS read was but I will put that down to how Windows reports things. Yup, everything I do is raidz2. On port multipliers, my understanding is that they are an entirely passive device, your OS doesn't need drivers for it, only the chipset on the mainboard needs to support port multipliers. Another observation - cifs write transfer are very bursty. I will see high speed initially, then it slowing down, but not uniformly, the transfer will just "stop", then burst a bit, then stop, then burst a bit, so on until the end. So I get the feeling it's transferring at say 40MB/s for a few seconds, then transferring nothing for another 5 or 10 seconds, then transferring at 40MB/s again, etc.

My knowledge of port multipliers is old, since I stopped caring about it when I discovered SAS, but my understanding was that the multiplier had a chipset, and that chipset has to be understood by the OS. I guess the fact that you can see the drives means I could be wrong, because if what I thought was true is, then you wouldn't be able to see them at all. I'm guessing that's with all 10 drives? I'd try to eliminate the PM and see what that does. The whole array is going to run at the speed of your slowest drive, so of the PM is slowing those disks down, it'll slow down the whole array. It's also possible, depending on the disks, that one of them could be bad. You could boot an Ubuntu Live CD and run some SMART tests to see.

I've got FreeNAS running some SMART tests now (at least, I think I do, I've scheduled them and they should have started 18 minutes ago but seeing as FreeNAS doesn't really give you any feedback as to whether they are running, I guess I will know if in 4 hours I don't receive an email with the results). Come to think of it, one of the drives might have sounded more noisy than usual... but that could be my imagination as well. Also, just to be clear, I'm not one of those posters ignoring everyone's advice because I don't like the sound of it, it's just that if I can't use the PM I'm sort of hosed because of some time limits I'm under, so I'm gonna try everything else first. After these tests run, I'll probably bypass the PM and do some testing without it.

File transfer speed is almost completely unrelated to ram and cpu power, at least for streaming video. (Transcoding is a different story, but I don't think we're talking about that.) An uncompressed bluray video stream is a trivial amount of bandwidth - you can do that over a USB 2.0 connection. I've got a Synology 411j and I can do a 14GB mkv + a couple other streams of various types. It's just not that taxing an activity. More important is you network infrastructure, the protocols you're using, and the devices on the other end of the NAS. For reference, it's a Snyology 411j (4 Spinpoint 1TBs in RAID5), connected to my streamers via a 500Mb powerline networking kit (actual transfer speed ~60Mb), and to several iDevices via wireless N/G.

Having said that, after I posted I decided I needed to have a look at what FreeNAS was actually doing and read up on smartd/smartctl/smartmon etc. After 4.5 hours I logged in and did a smartctl -a and most of the HDDs were at "10% to completion" and a couple were at 20%. That was something like 5 hours ago and I haven't had an email since then - maybe that means everything is AOK or it means a drive is stuck at 90% - a symptom I've seen described elsewhere of a dying drive. I guess I'll find out tomorrow when I have a chance to check it out.

I've got 411j, 4x1TB Spinpoints, CIFS and Windows File Sharing turned on. I have some wonky connection types, but: - Over the powerline networking my streamer reports ~60MB/s reads on average (can't test writes) - Copying to and from a Windows box over 5Ghz wireless N maxes out the connection at 10MB/s. Even at 10MB/s I can stream large (10GB) mkvs flawlessly - that's only about a 1.5MB/s transfer rate. Crackbone fucked around with this message at 21:29 on Apr 6, 2012 |

So, I factory reset my DS411j, reloaded the DSM software and reconfigured everything from scratch. I'm now seeing 40MB/s writes and 60MB/s reads with 1500 MTU. Not sure what was going on before but I've been using it like that for about a year and just assumed it was because of the specs. Here is my write speeds before:  And now:  As you can see my CPU was maxing out in the first image. Something was definitely wrong.

Follow up: I've removed the port multiplier, and dd write has given me ~90MB/s. CIFS is giving me 85MB/s to 90MB/s. To do this test, I actually only unplugged the PM and replugged in one of the HDDs direct to the mainboard, so the pool is running degraded. I'm going to put on my cowboy hat, migrate all the data to the pool in this state, then add the 2 drives back in. Reason being that the read stats were fine even with the PM in place, and those speeds will do until I can get a real RAID card. Having said that, I'm finding it difficult to believe I was so wrong on how the PM works that I'm going to be doing a bunch more research and testing to ensure I didn't configure things incorrectly.

I just got a NAS (Freecom SilverStore 2) and it gives me four options to configure the drives in it: single disk, stripe, span, and mirror. I'm guessing single disk is raid-0 and mirror is raid-1, but I can't seem to find a proper layman's explanation as to what the other two are. Can anyone shed a light on this?

Single disk = Exactly what it sounds like. You get one disk. Stripe = RAID 0 Mirror = RAID 1 Span = concatenation - it's like RAID 0 without striping. Data is distributed across all drives and presented as a single volume, but purely for convenience reasons. Generally easier to recover data in case of a failure. No extra performance gain from striping, no extra data security from mirroring.

wang souffle posted:This makes me think. What's the cheapest way to reliably run an ESXi box with BSD/OpenIndiana as a VM but with raw drive access to ensure ZFS performance is solid? I would assume a decent RAID/SAS card would be necessary. Would the IBM M1015 fit the bill or is the ESXi setup not a reasonable request? You're absolutely on the right track there. I have this setup in concept, except that I haven't yet added a M1015 and OI/ZFS yet because I don't have any intermediary storage to migrate the data off of my mdraid array. I am passing the onboard SATA controller directly to an Ubuntu VM and picking up the individual drives that way, and performance is just as good as native...even a bit better than the old / much lower horsepower system it was on before when it was running natively on the hardware. VT-d is actually better supported on AMD than Intel, because Intel wants to use it as a means to push you towards Xeons. With current-gen stuff you have to have at least an i5 processor, and it can't be a -K version. You also need a motherboard that both supports it and has it enabled, which is mostly server boards like Supermicro, but the Intel DQ67SWB3 also works (and is basically a server board minus the ECC support). If cost is your primary concern, and you don't get a screaming deal on a lightly used DQ67SWB3 and i5 2400 (thanks, kill your idols!) then the cheapest way to go is the AMD AM3 processor of your choice, and the Asus M5A97 board (this bad boy). AMD treats VT-d/IOMMU as an entirely chipset-based feature, so in theory it should be fine with even a shitass Sempron, though I only tested it myself with an FX-6100.
