11:09 vpeter Yay, ClearFog is ready to enter my house :)
17:38 wrexem Any guesses whether something like this would work on the HB? http://www.amazon.com/StarTech-com-Ethernet-Standard-Low-Profile-Supported/dp/B00V6ACHOA
17:39 wrexem I'm thinking of replacing my buffalo NAS with my hummingboard
17:40 wrexem Because the guts of the buffalo device are slow :(
17:40 wrexem specifically the SoC
18:13 wrexem My most ideal situation would be just removing the existing motherboard from the old NAS and clipping all the peripherals to the HB :D
18:13 wrexem I doubt that will happen though, there's some kind of daughter board which I don't believe is a standard fitting
18:13 jnettlet wrexem, what kind of drives?
18:13 wrexem They are SATA drives
18:13 jnettlet How many?
18:14 wrexem It's two; and while I realize that thing I linked is only one sata port I was thinking about usb 3.0-> sata
18:14 wrexem And I realize as well that I can get pci-e devices with sata and nic and etc
18:15 wrexem I'm guessing it would all just work...
18:15 wrexem I actually have all the stuff to go from the HB to a pci-e x16
18:15 wrexem which I expect would cover any needs I had
18:16 wrexem Just kinda experimenting, lol
18:18 jnettlet With all that great you could get a clearfog with some real nas power
18:18 jnettlet That gear
18:20 wrexem Would my i2ex uSOM fit in there?
18:23 jnettlet It is a Marvell usom very very fast io but a much bigger board
18:25 wrexem I have a pretty decent cpu sitting in my basement - I might yank the disks from the NAS and feed them to that thing. It's an i5 that toasted its power supply - but I have a bunch of extra ones from work.
18:25 wrexem I don't have the money for the ClearFog, it looks awesome though
18:26 wrexem The fact that it has an SFP port is amazing
18:27 wrexem Someday I'll set up a home network using fiber... it's so cheap these days.
18:29 wrexem I have some of these kicking around: http://www.flyteccomputers.com/details.cfm?wid=3423&wb=S-3553LC20D
18:29 wrexem They would be really good for pairing a couple of clearfog devices
18:29 wrexem Wouldn't even need a switch I don't think
18:30 wrexem single fiber instead of pair...
18:33 jnettlet I wonder if this would work on the HB. http://www.bplus.com.tw/Adapter/PM1061R.html
18:34 jnettlet PCIe 2 is a bit sketchy on the imx6...NXP released an errata that you needed an external clock to support it
18:34 jnettlet A bit late I may say
18:36 wrexem $42 on amazon lol
18:37 wrexem Since I have an x16 converter already, I can use an x16 SATA + NIC card - I think someone here ( malte_ ? ) was trying to capture video on the HB via a rig similar to mine.
18:56 wrexem IgorPec, do you know if 802.3ad adapter bonding works in any of your kernel builds?
18:57 mitchty would the hb2 be ok for using a sata ssd via a mpcie->sata card
18:57 mitchty or should i stick to using nfs for high(er) i/o
18:58 wrexe 18:58 * wrexem goes way out on a limb...
18:58 wrexem I think the mpcie is faster than the 470mb/s on the NIC
18:58 wrexem jnettlet is probably more qualified to answer that though.
18:59 mitchty sure but if its not reliable i'd rather not invest the $$ on things
19:02 mitchty i've already experienced the fun of those port multipliers acting... uniquely on x86
19:03 jnettlet mitchty, if you can solder there are pads for a sata connector on the hb2. On the top of the board by the m.2 connector
19:05 jnettlet The PCIe and Sata on the mx6 to out at about gigabit speeds... I have seen up to 128MB/s on my good msata ssd
19:06 wrexem (chiming in: I have a crucial ssd attached to my HB on the mSata connector and I get 105+ sustained write speeds)
19:07 wrexem http://puu.sh/mS2u2/58f5b4505a.png
19:09 wrexem I didn't realize there was a Sata pad on the device - that's very interesting to me.
19:13 wrexem haha, looks like I donated too long ago to make it on Igor's donor wall
19:16 wrexem jnettlet, is there a forum post I can follow which shows where the sata pins are at? Will it impede my using the mSata?
19:27 jnettlet wrexem, the pads are on the HB2 boards not the original HB
19:27 jnettlet The hummingbird only has mSata
19:28 wrexem ah
19:28 wrexem I didn't know there was an HB2
19:28 wrexem I might buy one of these to put on the HB: http://www.techpowerup.com/199305/axiomtek-debuts-the-shb230-picmg-1-3-half-size-single-board-computer.html
19:29 wrexem Is there a link for the HB2
19:32 mitchty i got the gate https://www.solid-run.com/freescale-imx6-family/hummingboard/
19:32 mitchty jnettlet: ah cool, i can solder didn't think that would be possible
19:32 jnettlet Gate and Edge are hb2 boards
19:33 jnettlet You will need to get power from the pin header
19:34 wrexem Can I slap my existing uSOM in an edge?
19:35 jnettlet wrexem, only if it has the three connectors. With the hb2 boards we brought out as many pins and connectors as possible
19:36 wrexem I think it's just two - were there revisions of uSOMs or something?
19:36 jnettlet The 2 header microsom can be forced to work but some connectors will not be supported
19:36 wrexem ah, interesting
19:36 jnettlet Yes kind of.
19:38 jnettlet Our initial consumer products all shipped with dual headers, then when we expanded the lineup we switched to three header soms.
19:43 jnettlet wrexem the sata header should work. Only the rest USB ports will work, and only random pins on the header.
19:43 jnettlet But for what you want to do it may be enough.
19:50 mitchty wrexem: i'd test without dd if you could, /dev/zero might be ignored as an optimization, like how zfs will just log a block is all zeros instead of write it
19:53 jnettlet That 110MB for sequential write sounds about right to me. Under load it probably drops down to about 80-86
20:17 wrexem mitchty, the problem with writing from somewhere other than dev/zero is that I don't have a fast source media.
20:18 wrexem "from ssd to ssd" is going to be under half, probably more like 30%
20:18 wrexem "fetch a block to memory over here, write it over there"
20:18 mitchty nah, just dd a meg of random bytes then just write that multiple times, won't be a great test but it'll show write speed
20:19 wrexem 704643072 bytes (705 MB) copied, 12.5904 s, 56.0 MB/s
20:19 wrexem that's a dd of an mkv file
20:19 wrexem should be random enough to suit
21:17 mk01 setting compress=off should be sufficient to use zeroes content with full allocations (assuming dedup is off as well)
21:30 wrexem mk01, how does one do that ?
21:32 mk01 wrexem: zfs set compress=off [filesystem]
21:32 wrexem oh; ok - I'm not writing to zfs, just ext4
21:32 wrexem Not sure how brave I would be with zfs on something with only a little RAM
21:33 wrexem Though I'm sure I could get a T or so out of 1GB
21:33 mk01 wrexem: the 32bit vmem barrier is issue, yes
