| 07:05 | Ghost9 | Is there an up-to-date kernel that builds for the original cubox out there? I noticed the rabeeh-kernel on github is outdated. |

| 12:46 | TrevorH | I built 3.14.8 yesterday and it boots and runs on a cubox-pro (non-i) |
| 16:52 | esin | hi |
| 16:53 | esin | Can I add more than three HDDs to Humminboard? 1 Hdd on eSata and then there are two USB hosts port, which mean I can I add multiple HDD's on one USB host port? |
| 16:54 | cbxbiker61_ | you can add as many as you like |
| 16:55 | esin | Good to know, thanks |
| 16:55 | esin | So the only limiting factor is USB 2.0 bandwith: = ~48MB/s |
| 16:55 | cbxbiker61_ | real world is way less than that |
| 16:55 | esin | I think Hummingboard can do around 30-40 MB/s iirc |
| 16:55 | esin | (meaning 30-40 MB/s ethernet) |
| 16:56 | esin | If it's around 25 MB/s it is still fast enough |
| 16:57 | TrevorH | there are limits on the number of hubs you can chain too, I think it's a maximum depth of 7 |
| 16:58 | deniska | maximum 127 devices one one bus I think |
| 16:58 | deniska | on one* |
| 16:58 | esin | Wow, 127 devices on one USB host bus? |
| 16:59 | deniska | theoretically =) |
| 16:59 | deniska | practically bandwidth and power are issues |
| 16:59 | TrevorH | 127 port usb hub has to have a 65W power supply ;) |
| 17:00 | esin | So I won't have scaling issues, because I just need around 3-6 HDDs at maximum |
| 17:00 | rabeeh | HB pro version has also onboard hub |
| 17:00 | rabeeh | potentially you can have 4 USB hosts |
| 17:00 | rabeeh | 1 dedicated and 3 through the hub |
| 17:03 | esin | rabeeh, So on the HB pro there are already four USB ports, or do I have to add jacks myself for the other two USB hub ports |
| 17:04 | rabeeh | actually there are 5 usb ports |
| 17:04 | rabeeh | 1 dedicated host port |
| 17:04 | rabeeh | second through the hub with a standard host port |
| 17:04 | rabeeh | 2 goes through 8pin header (like standard PC motherboard connectors) |
| 17:05 | rabeeh | and fifth goes to the mini pcie connector |
| 19:49 | Deslok | esin had you considered a SATA port multiplier if you needed more ports? |
| 19:49 | Deslok | (yes I realize that conversation was 3 hours ago) |
| 19:49 | deniska | can you multiply esata ports? |
| 19:50 | Deslok | they're fairly common, lots of 4-8 drive external enclosures that only have 1 or 2 ports |
| 19:50 | deniska | is it possible for esata without some sort of raid? |
| 19:50 | Deslok | the last place I worked I had a 8 port model under my desk |
| 19:51 | Deslok | typically jbod is the standard option but you can usually configure software raid if you want |
| 19:54 | Deslok | http://www.newegg.com/Product/Product.aspx?Item=N82E16817576001&cm_re=sata_enclosure-_-17-576-001-_-Product |
| 19:54 | Deslok | that's a good example of a 4 drive unit |
| 19:55 | Deslok | hell you could probably drill a hole in the case and mount the hummingboard inside of it |
| 19:56 | Deslok | but, regardless of the specifics sata offers a lot more bandwith to go around than usb 2.0 |
| 21:44 | esin | Deslok, Thanks that sounds like a good solution, since (I think) the arm cpu limits the ethernet 1 gbit/s anyways to 300-400 mbit/s, thus if I use a esata multiplier I would still have enough transfer rate (since esata has around 250 MB/s I think) |
| 21:53 | Deslok | yeah a fair bit better than usb trying to sift through 450mbit worth of connectivity, esata is 3gbps so you're seeing a 6-7 fold increase in potential bandwith before overhead using esata vs usb |
| 21:54 | Deslok | if you configure a raid you might actually see the full capacity of that port even(I know mechanical discs don't come close, the fastest 7200rpm drives i've used max out at ~2gbps) |
| 21:56 | esin | Ye, so I can copy stuff much faster between the backup drives. I guess I won't use raid though, because I don't need high availability. I'll just rsync --delete |
| 21:57 | TrevorH | don't know about the box you're talking about but the cubox-pro esata port won't go much faster than 100MB/s flat out |
| 21:59 | Deslok | that's still 4x the 25 you usually see on usb, have you tried it with a port multiplier? |
| 21:59 | Deslok | (sidenote 100MB/s=800mbps) |
| 21:59 | TrevorH | no, just an intel 160GB SSD which will manage 250MB/s on a desktop |
| 21:59 | esin | TrevorH, I took the 250-300 MB/s from esata on x86 machines. With 100 MB/s three esata drives would still suffice my speed ~25-30 MB/s for each drive, and I guess the multiplier works like a switch if the others aren't in use, then one esata port will get the full 100? |
| 22:00 | Deslok | that's how the multipliers i've used worked |
| 22:00 | esin | Great, sounds like the best solution then |
| 22:01 | Deslok | I just had a big 8 bay one for wiping drives we took out of servers(or preparing drives) in bulk you could watch the transfer rate per drive drop as it started writing to more than one and pick back up as things finished |
| 22:01 | TrevorH | and you're talking about a different box from mine which might be quicker (or slower) |
| 22:02 | Deslok | he was talking about a Hummingboard if I recall, should be the same hardware as a cubox-pro |
| 22:04 | TrevorH | google seems to think it's more like an -i |
| 22:04 | TrevorH | but I don't know, I'd never heard of til 10 mins ago ;) |
| 22:07 | esin | Ye, iirc the hummingboard is the raspberry alike design of the cubox-pro with just some slight hardware feature differences |
| 22:10 | lioka | except cubox-pro is just dove-based cubox with 2G RAM, and HB is imx-based, like cubox-ii |
| 22:11 | Deslok | when it comes down to it Freescale i.MX6 is going to have similar chipset limitations regardless of exact implementation(especially when we're looking at stuff all from the same vendor) |
| 22:18 | Deslok | actually if someone could make a 4 bay nas for ~100usd using one of these I wouldnt mind buying it even with the performance implications |
| 22:19 | bencoh | hmm, afaik humminboard is quite close to cubox-i |
| 22:19 | bencoh | (dunno what made you think of cubox-pro) |
| 22:20 | Deslok | (the quad core implimentation of the i.MX6 made me think of the CuBox-i4-Pro specifically) |
| 22:23 | Keizer | http://en.wiktionary.org/wiki/poronkusema |
| 22:23 | Deslok | actually, an interesting question I noticed some comments on the forum about having issues getting the micro-sd out of the cubox, is this particularly difficult? |
| 22:24 | Deslok | eh? keizer? |
| 22:25 | Keizer | Deslok: Sorry that's about how far I drive to work |
| 22:26 | Deslok | ahh |
| 22:33 | TrevorH | Deslok: I was talking about the older cubox-pro not a cubox-i-pro |
| 22:34 | Deslo | 22:34 * Deslok is new, hasn't seen the old cubox-pro |
