| MJCD | Is there something more user friendly/modern than znc ? | 15:08 |
|---|---|---|
| MJCD | It's web interface is pretty horrific | 15:09 |
| tomreyn | IMO the fact that it *has* a web interface makes it stand out. there's psybnc, i think there are also web interfaces for it. and there are probably znc forks (but i don't know whether any of these provide a nicer web interface). | 15:39 |
| MJCD | realistically idc if it has a web interface | 15:40 |
| MJCD | but ideally some kind of gui | 15:40 |
| MJCD | oh man cpanel and this um | 15:41 |
| MJCD | softaculous | 15:42 |
| MJCD | easy as hell | 15:42 |
| tds | MJCD: it's significantly more than just a bouncer, but thelounge is nice and modern and user friendly | 15:44 |
| MJCD | oh, i've heard of that | 15:47 |
| MJCD | what do you mean more than a bouncer | 15:47 |
| tds | it's a full browser-based client | 15:48 |
| tds | there's a demo instance somewhere if you want to try it without installing :) | 15:51 |
| MJCD | I will indeed as I am currently using a preconfigured copy of hexchat portable | 15:58 |
| MJCD | i'm imagining they charge $ for bouncer style services if you don't run it yourself eh | 15:58 |
| MJCD | run/host | 15:59 |
| ncuxo | hello | 16:08 |
| ncuxo | I have a dell r815 that doesn't recognize my drives | 16:09 |
| ncuxo | I used a flash ESXI hypervisor os with 6 sas drives and all was fine | 16:09 |
| ncuxo | today I wanted to switch to KVM and from #ubuntu told me that it would be better to get the os to an ssd | 16:10 |
| ncuxo | I've removed the sas drives and put two ssd but the server doesn't find any drives | 16:10 |
| ncuxo | except the flash boot drive | 16:11 |
| tomreyn | ncuxo: by KVM, do you mean kernel virtual machine then? or keyboard, video, mouse? | 16:32 |
| ncuxo | virtual mashine | 16:32 |
| tomreyn | if you'll do virtualization then most writes (and reads, too) will go to the VM storage. the OS storage doesn't has to be fast then. | 16:33 |
| ncuxo | so I could get the os to usb drive and get the sas drives back | 16:33 |
| ncuxo | I did it and it booted but then I was told that it would be way better to get an ssd and just put it in there | 16:34 |
| ncuxo | and that this will be more reliable than the usb stick | 16:34 |
| MJCD | tomreyn, no virtualization instructions for storage exist to date that i'm aware of | 16:35 |
| MJCD | thus, it all goes through the host | 16:35 |
| MJCD | impossible not to | 16:35 |
| tomreyn | MJCD: meaning? | 16:36 |
| tomreyn | i assume you wrote this to counter some of what i said? | 16:36 |
| MJCD | tomreyn> if you'll do virtualization then most writes (and reads, too) will go to the VM storage. the OS storage doesn't has to be fast then. | 16:37 |
| MJCD | false | 16:37 |
| tomreyn | so you're saying because the writes you do against the VM storage are also written on the OS storage? | 16:37 |
| ncuxo | MJCD: but the problem when I remove the sas drives and put ssd is that the server doesn't recognise the ssds | 16:38 |
| MJCD | it's impossible not to, given as I said there is no storage virtualization instruction set available currently | 16:38 |
| ncuxo | I've tried with ssd and sata not still not recognised | 16:38 |
| MJCD | ncuxo, SAS SSD's? | 16:38 |
| ncuxo | so should I use only sas drives | 16:38 |
| ncuxo | MJCD: regular ssd from old laptop | 16:39 |
| MJCD | well, I mean, if your rig is using SAS, you must use SAS drives, yes | 16:39 |
| ncuxo | dang | 16:39 |
| MJCD | whether they are ssd's or platter drives | 16:39 |
| ncuxo | because lff sata also is not reconised | 16:40 |
| ncuxo | I read somewhere that sata and sas should be compatable with each other | 16:40 |
| ncuxo | this is why I tried the recular sata drive(also from old laptop) | 16:40 |
| ncuxo | *regular | 16:41 |
| tomreyn | MJCD: hmm not sure i can follow though. obviously all data transfer goes over the same CPU(s), RAM, SAS controller as the OS storage would, but if you have, say a RAID-1 across two disks for OS, and a RAID-10 for the other four disks, then i don't think a write against a VM storage would actually end up on the OS RAID. It would pass through the virtualization hosts' RAM, and it'd be written to the VM storage. | 16:41 |
| MJCD | you're mixing/muddying between two different layers. The fact is regardless, without virtualization instruction set - it MUST pass through the host OS and is otherwise inaccessible | 16:42 |
| tomreyn | pass through the OS is not the same thing as end up on the OS storage | 16:43 |
| MJCD | no, but it does mean that it's a potential bottleneck/overhead | 16:43 |
| MJCD | and it's important to keep the layers separate otherwise you'll run into hypotheticals as above | 16:43 |
| MJCD | and to understand that's what's going on | 16:44 |
| MJCD | I do believe there are plans toward creating the instructions | 16:44 |
| MJCD | because it's potentially a real security problem potentially if things aren't configured well | 16:44 |
| tomreyn | so how would you do it with those 6 disks? | 16:45 |
| ncuxo | MJCD: okay then why there are sd card slots in the system if its going to be a bottleneck for the hypervisor os? | 16:45 |
| MJCD | a raid generates to the OS generally but 1 drive | 16:45 |
| MJCD | your vm's virtual disk exists on that "one" drive | 16:45 |
| MJCD | the rest is an OS-level concern | 16:45 |
| tomreyn | i can't tell whose question you just answered | 16:47 |
| MJCD | tomreyn> if you'll do virtualization then most writes (and reads, too) will go to the VM storage. the OS storage doesn't has to be fast then. | 16:50 |
| MJCD | false | 16:50 |
| MJCD | end | 16:50 |
| MJCD | <3 | 16:50 |
| tomreyn | hmm well in regards to writes to storage, which is all this statement was about, i continue to consider it correct. but we don't need to discuss this. | 16:51 |
| MJCD | ye | 16:51 |
| MJCD | done | 16:51 |
| MJCD | cpanel is being weird | 16:51 |
| MJCD | and I don't appreciate it | 16:51 |
| MJCD | I made 2 users | 16:51 |
| MJCD | [initials]@[domain].live | 16:51 |
| MJCD | set my own password at the time | 16:52 |
| tomreyn | ncuxo: personally i'd want to spin some form of mirror RAID across the OS storage. you could theoretically do this with flash storage on usb and sd card, but this is a rather bad idea, both because these are different physical media types, different controllers. and flash storage is short lived compared to other storage, and not very reliable. | 16:52 |
| MJCD | but cpanel won't let me log in as anything but the company name | 16:52 |
| MJCD | you CAN do that, I had a USB 3 hub with 5x 32gb sticks lol | 16:52 |
| ncuxo | tomreyn: this is why I guess I was told to put the os on ssd | 16:53 |
| MJCD | It wasn't worth the effort when 250gb ssd's are AU$30-50 | 16:53 |
| tomreyn | ncuxo: how would you connect this ssd then? | 16:53 |
| MJCD | most servers have atleast a couple of direct connections, without SAS | 16:53 |
| MJCD | mainly meant for the dvd drive included | 16:54 |
| tomreyn | r815 has one internal usb port | 16:54 |
| ncuxo | but since I have to use sas ssd and I don't have one I'll see if I can get the os on the sas drives | 16:54 |
| MJCD | or a vertical riser that has a specific ssd slot | 16:54 |
| MJCD | though most will just have a general purpose pcie | 16:54 |
| ncuxo | MJCD: I haven't thought about pcie card just for the ssd but good Idea | 16:55 |
| MJCD | fastest, obviously :) | 16:55 |
| MJCD | and not serial | 16:55 |
| MJCD | which comes with big async benefits | 16:55 |
| tomreyn | ncuxo: i guess you could use pcie nvme's | 16:56 |
| ncuxo | don't have those laying around | 16:56 |
| tomreyn | also servicing those is annoying | 16:56 |
| MJCD | pcie doesn't neccisarilly == nvme | 16:56 |
| MJCD | if you can use nvme, that's even better ofc | 16:56 |
| MJCD | but support is not tied to pcie in any way, separate connector even (m.2) | 16:57 |
| MJCD | I got an xps 12 sitting here with a dead screen backlight or something screen related | 16:58 |
| MJCD | 250GB NVME | 16:58 |
| MJCD | need like $200 to get it repaired officially | 16:58 |
| MJCD | cause too fiddly to do myself being a 2 in 1 convertable | 16:58 |
| MJCD | with ultraslim bezels on which the screen revolves | 16:58 |
| MJCD | lol | 16:58 |
| MJCD | but it's like a $1100 laptop even second hand as is | 16:59 |
| MJCD | er, as is but working | 16:59 |
| MJCD | lool | 16:59 |
| tomreyn | ncuxo: so if those are sata ssd's you could buy a sata controller (which is cheap), put this into the pcie slot, and have it manage two ssds. but you'd still need to find a place to put those ssds, where they don'T break the airflow. | 16:59 |
| ncuxo | I think I have a sata controller somewhere laying arround | 17:00 |
| ncuxo | brb | 17:00 |
| tomreyn | think about the storage location first,though | 17:00 |
| ncuxo | on top of the cpu shield | 17:01 |
| tomreyn | covering the cpu fan then? | 17:03 |
| MJCD | errr | 17:03 |
| MJCD | as I said before | 17:03 |
| MJCD | MOST servers will have atleast 1 sata port (what model is it?) | 17:04 |
| MJCD | and secondly SAS exists for a good reason | 17:04 |
| MJCD | you may want an SSD for your OS as you said | 17:04 |
| MJCD | that makes sense | 17:04 |
| MJCD | for 98% of your data though, put in platter SAS drives | 17:04 |
| MJCD | the more drives even if small capacity, the better | 17:04 |
| MJCD | SAS ensures clean IO | 17:05 |
| MJCD | it's pretty essential to a server | 17:05 |
| MJCD | the same way as ECC ram is | 17:05 |
| MJCD | can't have data getting corrupted randomly | 17:05 |
| MJCD | that's bad news for anybody, let alone for any kind of commercial service | 17:05 |
| ncuxo | MJCD: I need the sata only for os | 17:10 |
| MJCD | ncuxo, what modelllll | 17:11 |
| ncuxo | model? | 17:12 |
| MJCD | of server | 17:12 |
| ncuxo | as said noob to servers | 17:12 |
| tomreyn | dell r815, as he said in the very beginning | 17:12 |
| ncuxo | r815 | 17:12 |
| ncuxo | dell | 17:12 |
| tomreyn | https://www.dell.com/downloads/global/products/pedge/en/Poweredge-R815-Technical-Guidebook2010.pdf | 17:12 |
| ncuxo | yes | 17:12 |
| MJCD | damn that's nicer than mine >:p | 17:12 |
| ncuxo | you wouldn't imagine for how much I bought it :D | 17:13 |
| tomreyn | ncuxo: do you know which PERC storage controller you have in there? | 17:13 |
| MJCD | so that has a sata connector | 17:13 |
| MJCD | right next to um | 17:13 |
| ncuxo | 64 cores 256 ram 1.5 v I want to exchange it to 1.35v for 243 euro | 17:14 |
| ncuxo | ebay :D auction | 17:14 |
| MJCD | http://prntscr.com/ohr6uu | 17:14 |
| ncuxo | perc 700 | 17:14 |
| MJCD | @ ncuxo | 17:14 |
| MJCD | ncuxo, how much? | 17:14 |
| ncuxo | is the storage connector | 17:14 |
| MJCD | that's just a sata port | 17:15 |
| MJCD | it will probably look like SAS | 17:15 |
| MJCD | as it's got both power and data together | 17:15 |
| MJCD | you will need a female to female power cable | 17:15 |
| MJCD | should have been included but if second hand, easy to go missing if not used | 17:16 |
| ncuxo | I already put the sata pcie card | 17:16 |
| MJCD | just get a $50 pcie ssd | 17:16 |
| MJCD | save the hastle | 17:16 |
| MJCD | you don't need a sata controller | 17:16 |
| MJCD | use SAS drives upfront | 17:16 |
| MJCD | for good reason | 17:16 |
| MJCD | (s) | 17:16 |
| ncuxo | MJCD: I will use the sata only for the os | 17:17 |
| MJCD | just seems silly is all | 17:17 |
| MJCD | but if you have the cable required | 17:17 |
| MJCD | off you go | 17:17 |
| MJCD | :D | 17:17 |
| MJCD | MOST people don't boot from SAS | 17:17 |
| MJCD | thus why there's generally atleast 1 sata port | 17:18 |
| compdoc | i don't boot from SAS | 17:18 |
| MJCD | my $45 200gb pcie ssd pulls through 1600mb/s read/write | 17:18 |
| MJCD | for 3200mb/s total | 17:18 |
| MJCD | many flagship cpu's can only process upto around 50gb/s | 17:19 |
| MJCD | (each, yours can have 4 so not really a concern lol) | 17:19 |
| ncuxo | okay another stupid question how to power the ssd | 17:20 |
| MJCD | I told you already | 17:20 |
| MJCD | >.< | 17:20 |
| MJCD | I literally said "you will need x cable for power" | 17:20 |
| MJCD | lol | 17:20 |
| ncuxo | lol missed that sorry | 17:20 |
| MJCD | lol all good | 17:20 |
| ncuxo | well the cable not included | 17:21 |
| ncuxo | but I have some from the risers I used for mining back then | 17:22 |
| MJCD | just get a pcie ssd, for the third/fourth time | 17:23 |
| MJCD | :P | 17:23 |
| ncuxo | I wanna do it now | 17:23 |
| MJCD | nvme if you can afford it, but all of them are way fast enough | 17:23 |
| ncuxo | not ordering stuff and wait days :D | 17:23 |
| MJCD | so go to a pc parts store ? | 17:23 |
| MJCD | they are hardly rare | 17:24 |
| MJCD | it's consumer level hardware | 17:24 |
| ncuxo | not in germany | 17:24 |
| ncuxo | everything is closed on Sunday | 17:24 |
| MJCD | you CAN buy enterprise level ones but frankly they're ssd's, they don't suffer many issues requiring paying extra | 17:24 |
| ncuxo | as I've said couple of days | 17:24 |
| ncuxo | I hate waiting :D | 17:24 |
| MJCD | so then you'll have to wait a day jeez | 17:24 |
| MJCD | I hate you | 17:24 |
| MJCD | ;p | 17:24 |
| ncuxo | haha | 17:24 |

| ncuxo | one is going to be NIC | 23:04 |
| ncuxo | what else | 23:04 |
| ncuxo | I already have perc 700 raid controller | 23:08 |
| compdoc | yeah, but do you have the new spatial anomaly pci-e card? its a must have | 23:30 |
| mybalzitch | high quality sound card is a must to tone out fan noise | 23:30 |
| mybalzitch | *tune | 23:31 |
| ncuxo | yeah right :D | 23:31 |
| ncuxo | I have 5 free pci slots and wanna fill them with something just don't know what | 23:32 |
