Thanks for also teaching me a new word I really wish I could buy a 8 or 12 bay DAS that used external SAS connectors and was the exact form factor of a Synology. I have a computer that's got 8 disks now in an NZXT 440 and I love ZFS and janitoring everything myself but external expansion basically seems to be a non-starter except for garbage looking Thunderbolt enclosures. If I wasn't in an apartment I could look at rackmount gear but the noise and size sort of kills the deal. Are there any enclosures like the NSC-800 (which seems impossible to get now) that could function as an external JBOD?

I think you're looking for an "8-bay SAS/SATA/JBOD enclosure". https://www.newegg.com/mediasonic-h8r2-su3s2/p/N82E16816322007 https://www.newegg.com/p/1UW-0038-00004 https://www.newegg.com/sans-digital-tr8ut-bn/p/N82E16816111488 NAS chassis like the 810A could work fine too, there's just 8 SATA plugs in there so you should be able to plug them into a mini-SAS octopus cable, then provide 2x molex somehow to power the backplane...

Yeah honestly at this point I'm thinking of getting some SFF (or not) case and just rigging the power supply with an ATX testing switch and connecting the second case to the main PCI via an LSI external HBA. Huge footprint though for a small amount of disks, especially when looking at the more dense Synology units: https://www.synology.com/en-global/products/DS2419+ And yeah the rackmount stuff is way too large for a small apartment. If I had a garage I would have... several racks.

Everything I have found "off the shelf" with a SAS connector is either crazy expensive or crazy physically large. A backplane with a PSU and some drive sleds doesn't need to be that deep!

There will probably be others although probably not that cheap. (and then you had to either swap out the IOMs, or source a Netapp card to control it, about another $40 to get to the point where you could use standard SAS cards/cables) But it depends on how short, once you go smaller than standard rack depth and start white-boxing it's up to you to make sure it fits

Unfortunately my cabinet's rackposts are 16.5" apart with 3" of space in the front and back, so most short-depth enclosures are still too big. I've been looking at external SAS enclosures opposed to storage server boxes as the length of both an mATX board and a 3.5" hdd is over 15", removing any possibility of a backplane for external access to drives. I did look at Norco RPC-4308 but there's no fans for the drives and I wasn't very impressed by the build quality of the RPC-432 I realize my situation is non-standard and stupid.

woo, got my connectx-2 IB QDR/10GbE cards to work in ipoib mode on freebsd 12  documentation was a bit out of date when I first tried, using the new config script that set connected mode helped (it was set on ubuntu but I didn't realize what I was looking at), plus I also needed to manually ifconfig a static IP. with two cables direct connected between the two NICs I was pushing 16 gbit/s over iperf... presumably that means both were working? but trying to assign a different static IP to both ports on the adapter and explicitly binditng to the second didn't work. eg ubuntu: ib0=10.0.0.1, ib1=10.0.0.2 freebsd: ib0=10.0.0.3 ib1=10.0.0.4 freebsd could iperf to either .0 or .1 via explicitly binding to .3 but explicitly binding to .4 couldn't connect to anything at all. I guess maybe accepting any IP over any interface is a default linux behavior? or maybe it's a bad cable or config issue... didn't track it too much further. or maybe >10gbit speeds on IP means both ports are ganging properly? somehow? without config? I think it's only supposed to be a 10gbit link in ipoib... Paul MaudDib fucked around with this message at 10:39 on Oct 17, 2019 |

They're just not used very often because a SSD + HDD is generally a better option for most people. SSHDs are really only good ideas for single-drive systems that you don't want to spend the money on a full SSD for.

Smashing Link posted:Gentlemen, would any of you consider this to be a good deal (Fb posting): For 200 I’d say yes, 400 seems pretty steep. Sandy Bridge is old, loud, hot, and nothing fancy unless the price is right. DDR3 RDIMMS are very cheap (like $30 per 16GB) and those are some fairly low-tier processors. GPU could be flipped and replaced with something minimal but it’s probably a Quadro equivalent of like a GTX 660 or something, old and nothing fancy.

I agree, $400 is way too steep. I got myself a IBM X3650 M3 with two quad-core Xeon E5600/Westmere-EP series with SMT at 2.4GHz and 96GB ram for the equivalent of $149, and there's basically no micro-architectural difference between Westmere-EP and Sandy Bridge, so the only thing you get for $240 is 4 more cores. Also, I keep seeing X5690 with 6 cores at 3.46GHz for insanely cheap, so I'm thinking that I might wanna grab a pair of those - then I'll have a CPU that's as fast as my workstation, with 12 cores instead of 4.

HalloKitty posted:No architecture difference between westmere and sandy? Really? That doesn't sound right at all X5600 to E5-2560 was a really minor incremental step. I saw the most horsepower jumping to the v2 of that arch. I don't know what you're doing on your NAS but I wouldn't buy a xeon for my house when the cloud exists. What were we talking about?  (I bought several thousand cores each of E5500, E5600, E5-2620 (v1, 2, 3, 4). If you can find em I would go with v2 or v4 of that list.)

Yeah, core versus core, E56xx and E5V1 are pretty similar. Where the E5V1 is miles ahead is that it can be replaced with an E5V2 with generally no more than a BIOS update, if even that. I have E5V2s in my box for that exact reason. Of course if I still had this thing at home I probably would have replaced it with some sort of newer single-proc setup instead to cut on power draw.

Yeah, if you can find a E5-2667 v2 for cheap enough, you've got yourself one heck of a home-lab, but even used they tend to go for +$150 and you can't just use one, as far as I remember.

I got mine for free but I've hit way below market value on pretty much all of the hardware in my box other than the drives themselves. And even with those chips, transcoding 4K makes them cry. Speaking of market rate, is it just me or has it been a while since the last deal on hard drives? I had some of my 40-50k hour WD30EFRX drives start dying so I snagged some used Hitachi 3TB SAS drives to hold me over until Black Friday, when I'm hoping there will be a good deal on either 8TB or 10TB so I can replace one of my vdevs, and effectively have a ton of spares for my remaining high-hour 3TB drives.

HalloKitty posted:No architecture difference between westmere and sandy? Really? That doesn't sound right at all That’s because it’s not right at all. Sandy uarch was not a clean sheet break from Westmere, but a ton of things changed. Foundational stuff like how the register files worked (centralized Physical Register File in Sandy, Retirement RF in Westmere and earlier), Intel’s first use of an on-die ring bus interconnect for last layer cache, the debut of AVX256, and much more.

I’m not sure if this is the right place to ask this, but here we go. I was hoping someone could help me with an Unraid build (and I'm looking at Unraid just because it looks easier to use than some of the other options). I would like to spend $1000 or less (not including drives) and it would be used for mass storage and hopefully as a Plex server. I like this case (Rosewill 4U Server Chassis with 12 hot-swap drive bays) https://www.amazon.com/gp/product/B00N9CXGSO/ref=crt_ewc_img_huc_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER but I’m not married to the idea, or if there is a used solution I could find on eBay, I would be down for that as well. I am a NAS noob and would love some help and hand-holding.

How many plex streams do you plan on serving at a time? Will you be running other services on the NAS as well (VMs, docker containers, torrents/usenet) or just storage + streaming? How much storage space do you need? How much storage space do you want? Do you have somewhere to put the 2ft x 1.5ft box where you won't be bothered by the noise?
