| 14:51.37 | vagarwal | howdy yaMatt |
| 14:52.10 | yaMatt | hey vagarwal |
| 14:52.24 | vagarwal | my head hurts, spent all day working in the comms room trying to revive two arcsight units |
| 14:53.02 | vagarwal | our security team discarded them |
| 14:53.57 | vagarwal | they are actually dell r710 and quite beefy. however, the bios is customized and i don't know the password |
| 14:54.43 | vagarwal | i have removed the cmos battery and i will wait until monday |
| 14:54.47 | yaMatt | arcsight >.< |
| 14:55.51 | vagarwal | we don't have budget for _experimenting_ |
| 14:56.22 | vagarwal | so if i need bare metal servers, i need to look into discarded tech :/ |
| 14:56.43 | yaMatt | not gone virtual? |
| 14:57.46 | vagarwal | we do have huge virtual infra (all vmware) but i am working on zfs, swift and kvm |
| 14:58.30 | yaMatt | ah, I see |
| 14:58.32 | vagarwal | and i need something that is more local than in washington dc |
| 14:58.38 | yaMatt | ha! |
| 14:58.58 | yaMatt | my problem with older hardware is the power consumption is usually huge on them |
| 15:01.39 | vagarwal | that is true |
| 15:02.00 | vagarwal | is anyone using zfs for enterprise fileserver? |
| 15:02.07 | vagarwal | ^ wethrin |
| 15:02.53 | yaMatt | not enterpise no, just at home |
| 15:03.39 | vagarwal | i am looking for a *realiable* to setup remote synchronous replication |
| 15:04.18 | vagarwal | i know we can send it over ssh |
| 15:04.45 | yaMatt | there are tools like ceph that do that sort of thing too |
| 15:05.32 | vagarwal | have you used ceph as a fileserver? |
| 15:06.43 | yaMatt | nope |
| 15:07.18 | yaMatt | it's block level, I've seen it used for VMs |
| 15:07.44 | vagarwal | ok |
| 15:08.08 | vagarwal | i reckon you run freenas and zfs for your home file server |
| 15:08.37 | vagarwal | do you run that on a desktop pc? |
| 15:08.57 | vagarwal | i am looking for something like a raspi but with sata ports |
| 15:09.11 | vagarwal | i guess bananapi doesnt have sata ports either |
| 15:12.34 | yaMatt | it's an Intel Atom server level board, ECC memory and everything |
| 15:12.43 | yaMatt | the Banana Pi has 1 SATA |
| 15:13.02 | yaMatt | not sure the state of the ZFS on Linux project though |
| 15:19.12 | wethrin | I'm using it at home and at work, but nothing enterprise |
| 15:19.20 | wethrin | I wouldn't have an issue using it in Enterprise, thoug |
| 15:19.54 | wethrin | ZFS on Linux is reasonably stable |
| 15:20.06 | wethrin | Not sure how up to date it is. But it's sufficiently up to date for most things |
| 15:22.41 | yaMatt | does it support all the shiny bits though? |
| 15:25.26 | vagarwal | i find zfs a good candidate for a fileserver exposed using a nfs |
| 15:25.56 | vagarwal | however, one of the conditions is that this server should have an active-active replication to a dr site |
| 15:26.26 | vagarwal | essentially replacing windows dfs servers |
| 15:28.15 | vagarwal | i dont like the idea of setting up a offsite replication using ssh |
| 15:28.41 | wethrin | zfs send | ssh |
| 15:28.43 | wethrin | Simple :) |
| 15:29.00 | wethrin | But maybe you could use a network block device as one of the elements of your zpool |
| 15:29.07 | wethrin | If you're feeling sick and wrong |
| 15:29.13 | vagarwal | it works well but what happens on a connection drop |
| 15:29.21 | vagarwal | might need to write a daemon that will take care of it |
| 15:32.05 | vagarwal | need to test the behaviour of zfs when the network block device become unavailable intermittently |
| 15:32.47 | vagarwal | or perhaps, setup an ipsec tunnel and use nc for the job |
| 15:38.26 | vagarwal | yaMatt: how much was that server? ZoL is pretty good so far on both Debian Stretch and Ubuntu 16.04 |
| 15:39.05 | yaMatt | I paid about £400 inc. 10Tb raw disk |
| 15:39.38 | vagarwal | thats a good price, i might consider that |
| 15:39.54 | yaMatt | oh, not including disks actually |
| 15:40.01 | yaMatt | http://uk.pcpartpicker.com/list/zDVJ4D |
| 15:40.11 | yaMatt | about £50 for the case but I can't find my purchase order |
| 15:40.33 | yaMatt | you could EASILY do it much cheaper |
| 15:41.02 | yaMatt | but I figured it was a lifetime investment |
| 15:43.24 | yaMatt | but it turned out the caddies were unnecessary |
| 15:43.57 | yaMatt | got to do a 4Tb upgrade at some point in the next 2 years |
| 15:44.27 | vagarwal | are you running raidz or mirror+stripe? |
| 15:45.36 | yaMatt | raidz |
| 15:46.00 | yaMatt | it's the only option really on FreeNAS |
| 15:46.09 | vagarwal | ah ok |
| 15:46.41 | vagarwal | that board is expensive |
| 15:46.47 | vagarwal | how much was the processor? |
| 15:47.17 | yaMatt | the board includes the processor |
| 15:47.23 | vagarwal | i see |
| 15:47.24 | yaMatt | has 12 SATA ports |
| 15:47.45 | yaMatt | that is the lower end one so it's passively cooled too |
| 15:48.07 | vagarwal | atom is good in that sense i guess |
| 15:48.27 | vagarwal | low heat |
| 15:48.32 | yaMatt | I haven't tried transcoding on it, I don't intend to, but it comfortably handles everything |
| 15:48.41 | yaMatt | and yeah, I wanted something that draw as little power as possible |
| 15:48.50 | vagarwal | i had a corsair platinum psu for my litecoin rig back in the days |
| 15:48.55 | wethrin | I've got a couple of PCI cards with 6x SATA ports on them. Anyone interested? |
| 15:48.56 | vagarwal | they are very quiet |
| 15:49.00 | yaMatt | which is why the PSU is massively over-spec'd and expensive, I wanted the highest efficiency I could |
| 15:49.49 | yaMatt | also why some of the disks are the green ones |
| 15:50.09 | yaMatt | but in the end I concluded for a NAS the longevity of the data was more important |
| 15:50.18 | vagarwal | is that due to huge bills or concern for mother nature? |
| 15:50.22 | yaMatt | replaced one of the green disks after 2 years |
| 15:50.26 | yaMatt | bills mainly ;) |
| 15:50.36 | vagarwal | haha, ok |
| 15:50.42 | vagarwal | wethrin: how much? |
| 15:50.50 | vagarwal | for that card? |
| 15:51.48 | vagarwal | i already invested in a skylake pentium g4400 |
| 15:52.20 | yaMatt | I think Intel don't do the Atom range any more, which I think is a huge shame, they're great CPUs |
| 15:52.23 | vagarwal | however, i need to rethink about keeping it on all day long |
| 15:52.59 | vagarwal | i didnt know intel dropped atom processors |
| 15:53.27 | wethrin | vagarwal: Postage cost? |
| 15:53.29 | yaMatt | there was something at the beginning of the year |
| 15:53.54 | yaMatt | vagarwal, get one of those Watt meters to see what kind of draw you're dealing with |
| 15:54.53 | yaMatt | http://www.techtimes.com/articles/155250/20160502/intel-drops-atom-processors-what-this-means-for-the-surface-phone.htm |
| 15:54.55 | vagarwal | wethrin: yeah |
| 15:55.03 | yaMatt | but then https://pressinsiderdaily.com/2016/07/xiaomi-notebook-unveiled-27th-july-intel-atom-processor-expected.html |
| 15:55.14 | wethrin | vagarwal: Okay. Let me find them first :) |
| 15:55.19 | vagarwal | yaMatt: i really need one of those |
| 15:55.24 | wethrin | They won't give you blistering performance, mind |
| 15:55.52 | vagarwal | ok |
| 15:56.08 | yaMatt | oh, although that second one isn't about a new CPU, it's about a phone having an Intel CPU |
| 15:57.08 | yaMatt | with a NAS, and especially if it's RAID'd you might not need to be too worried about performance |
| 15:57.18 | yaMatt | the disks themselves are usually pretty slow, but fast enough |
| 15:57.24 | wethrin | It worked well enough for me when I was using them |
| 15:57.41 | wethrin | I then moved to an HP microserver |
| 15:58.25 | vagarwal | maybe supermicro does some kind of multi socket arm board |
| 15:59.02 | yaMatt | if you think you can live with 4 disks then the HP Microserver is an excellent option |
| 15:59.19 | wethrin | You can put a 5th disk in the CD slot |
| 15:59.55 | vagarwal | http://www.serversdirect.co.uk/hp-proliant-gen8-g1610t-microserver-819185-421/version.asp?refsource=SDadwords&crtag=SD&gclid=COG28afr9c0CFRUW0wodkpECYQ |
| 16:00.00 | vagarwal | thats cheap |
| 16:00.15 | yaMatt | I just worry what happens when it comes to upgrade time, but I suppose you could remove one disk and put the 2 new ones in |
| 16:00.34 | yaMatt | does that include the rebate? Usually there's a £100 rebate |
| 16:00.50 | yaMatt | oh wow, they'd be paying you if there was a rebate on that XD |
| 16:00.51 | vagarwal | oh i see, something like a cashback? |
| 16:01.04 | yaMatt | ah, £45 rebate, yeah |
| 16:01.07 | yaMatt | still, very cheap |
| 16:01.53 | yaMatt | it is definitely the way I'd start |
| 16:02.33 | yaMatt | ~£150 for 2x 2Tb drives |
| 16:03.55 | vagarwal | a custom nas server for ~£250 - not bad |
| 16:04.24 | yaMatt | might need a USB key or something for the OS, but they're easy enough to get hold of |
| 16:05.15 | vagarwal | ok |
| 16:06.18 | vagarwal | it has an ilo as well |
| 16:11.38 | yaMatt | can't get away from it these days :) |
