Not sure how failover would be
2018-11-09 06:55:50
Fireduck
and using that nvme makes the box crash
2018-11-09 06:55:52
Fireduck
great
2018-11-09 06:55:59
Fireduck
I hate hardware some times
2018-11-09 07:08:48
Fireduck
put it in a different machine, still only detected one NVME.
2018-11-09 07:09:02
Fireduck
@Clueless I'll be come all day tomorrow, want to come get this thing and see if you can do something with it?
2018-11-09 07:09:15
Fireduck
I just don't have that much mucking with hardware time.

I love it when a GFCI trips taking down the server that takes 30 minutes to load the chunks back into ram

fibre channel?

here's a decent writeup of why i like to push 35W TDP non-turboable processors on people https://www.anandtech.com/print/13544/why-intel-processors-draw-more-power-than-expected-tdp-turbo Why Intel Processors Draw More Power Than Expected: TDP and Turbo Explained

Fireduck
I like my processors to actually be on fire
2018-11-09 21:26:25
Rotonen
you need a sparc
2018-11-09 21:26:50
Fireduck
a spark is like fire
2018-11-09 21:27:08
Fireduck
sparc, were those those fancy purple boxes that no one ever let teenage me touch?
2018-11-09 21:28:11
Fireduck
no, I am thinking of the SGI stuff
2018-11-09 21:29:12
Rotonen
well, at least XFS survived that
2018-11-09 21:29:43
Rotonen
ultrasparc hardware was also purple themed so could be you blend the two at this point already
2018-11-09 21:30:40
Fireduck
yeah
2018-11-09 21:31:32
Rotonen
i'd call those fancy purple boxes
2018-11-09 21:32:19
Fireduck
looking it up, I was remembering the sgi machines that were big purple cubes
2018-11-09 21:32:37
Rotonen
if you remember this, you fiddled with one
2018-11-09 21:32:44
Rotonen
you could bring down the X11 very easily on irix
2018-11-09 21:33:31
Fireduck
I was never allowed to touch one
2018-11-09 21:34:11
Fireduck
always in the context of "hey, look at this fancy lab with fancy boxes" as part of a quick tour

I did help carry hardware around when Virginia Tech decided to build one of the largest (at the time) super computers out of Mac towers and infiniband.
2018-11-09 21:35:38
Fireduck
They wanted the 1U mac servers, but those weren't ready yes so phase 1 was towers, three on a shelf. 3 or 4 shelfs to a rack.
2018-11-09 21:35:57
Fireduck
We had to unbox, install infiniband card, haul to shelf
2018-11-09 21:36:08
Rotonen
m68k supercomputing, or wut?
2018-11-09 21:36:20
Fireduck
this was probably in 2003 or 2004
2018-11-09 21:36:42
Rotonen
so ppc
2018-11-09 21:36:49

heh, nested access interleaving is becoming a thing - let's hope they do not trip up on their own cleverness https://www.anandtech.com/print/13579/in-the-lab-double-capacity-2x32gb-ddr4-from-gskill-and-zadak In The Lab: Double Capacity 2x32GB DDR4 from G.Skill and ZADAK

@Rotonen do our shit consumer motherboards support PCI-E bifurcation?
2018-11-09 21:38:15
Rotonen
probably not
2018-11-09 21:38:32
Fireduck
nothing sees anything other than first slot
2018-11-09 21:38:45
Rotonen
the specs sheet of the asus card is so mum i'm very sceptical of recommending it
2018-11-09 21:38:57
Rotonen
it seems more like a workstation card by design, and they're not actually telling what it is
2018-11-09 21:40:33
Rotonen
amazon reviews say people have had 1-3 slots working and in general apparently badly put together
2018-11-09 21:40:52
Rotonen
now this is gonna sound weird, but heat it up with a hair dryer for a bit and try again
2018-11-09 21:41:02
Rotonen
probably bad solder reflow
2018-11-09 21:41:27
Rotonen
google for the ps3 fix, probably same problem
2018-11-09 21:45:34
Rotonen
actually it's software lock-out of VROC it seems - ASUS should never have made that a consumer product

2018-11-09 21:46:01
Rotonen
what i'm parsing from that your motherboard can implement hackery to fake a license key and fake the IDs of your SSD to be in line with what intel expects
2018-11-09 21:46:14
Rotonen
so update UEFI and hope for the best?
2018-11-09 21:48:08
Fireduck
hair dryer over oven at some low temp?
2018-11-09 21:48:13
Clueless
@Rotonen customer reviews say that it works as a multinvme card on motherboards with pcie bifurcation, and the manual says the VROC only works on a specific motherboard thing.
2018-11-09 21:48:40
Clueless
I don't think our motherboards have pcie bifurcation.
2018-11-09 21:48:45
Rotonen
@Fireduck depends on the solders used, but probably not that issue you are facing
2018-11-09 21:49:04
Rotonen
dunno if it's *only* that, it would seem like the motherboard also needs to lie to the intel chip on the asus riser
2018-11-09 21:49:35
Rotonen
that intel community thread is a bit vague and repeatitive, but seems like all the essentials are actually covered there
2018-11-09 21:50:43
Clueless
@Fireduck I don't like the idea of relying on badly documented, one off products. :/ RAM might be more reliable.
2018-11-09 21:51:39
Rotonen
pci-e is very complicated beyond 'plug gpu in'
2018-11-09 21:51:53
Fireduck
Ha. Fun times.
2018-11-09 21:51:57
Clueless
it's just legos / tinker toys
2018-11-09 21:53:33
Rotonen
ok, so, yeah, you do need bifurcation for the base operation - you need to be able to explicitly set the slot to 4x/4x/4x/4x
2018-11-09 21:53:33
Clueless
@Fireduck I say we try a specifically pcie bifurcation motherboard, or give up on this card.
2018-11-09 21:53:45
Clueless
unless their specific motherboards are common and cheap.
2018-11-09 21:53:59
Rotonen
damn i'm like 5 years behind on what's going on in pci-e, this is good stuff i'm encountering
2018-11-09 21:54:12
Rotonen
so, extra fun, but not all bifurcation can split into 4
2018-11-09 21:55:12
Rotonen
so it could just as well be you've not set up the UEFI settings for the slot right
2018-11-09 21:56:19
Rotonen
and apparently that's not a hardware feature either, just UEFI level implementations
2018-11-09 21:56:35
Rotonen
so you might be able to just hack in an uefi script as that's a handshake rewrite under the hood
2018-11-09 21:56:44
Clueless
really, that's cool

ref. https://software.intel.com/en-us/articles/efi-shells-and-scripting Introduction Extensible firmware interface (EFI) brings new flexibility and opportunities to users by allowing them to work in the layer between their OS and BIOS, without altering either one. This paper explains how to use EFI shell commands, create a script file and set up the boot menu with shells and scripts. In addition, this paper demonstrates dual boot selection for the 64-bit Red Hat Linux* 7.1 and 64-bit Microsoft Windows* XP Professional operating systems.

chipsec is good stuff to have in your browser caches when getting caught at border crossings :stuck_out_tongue:

backup your stuff to the cloud, take out your storage from your computer when you travel.
2018-11-09 22:02:04
Rotonen
easier to just buy a laptop on-site if going on a trip like that
2018-11-09 22:05:42
Clueless
@Rotonen so what do you suggest we do from here?
2018-11-09 22:06:09
Clueless
try to write our own uefi thing to handle pcie bifurcation? find a cheap motherboard that supports bifurcation? give up and use ram
2018-11-09 22:06:36
Clueless
@Fireduck so what causes your ram machine failure anyway? My guess is power, I have an extra UPS if you want to try that out.
2018-11-09 22:07:31
Rotonen
@Clueless email the motherboard vendor, email asus
2018-11-09 22:11:34
Clueless
@Fireduck on another website ``` Check (960 PRO pic here). Note that the ASUS Hyper M.2 X16 Card will only work on motherboards supporting PCIe bifurcation, which allows the CPU to split PCIe lanes into subgroups without the need of a PLX chip. You can see two bifurcated modes in the above screenshot ```
2018-11-09 22:19:26

Vs $200 for a real 4 nvme card?
2018-11-09 22:21:58
Clueless
$399 - http://a.co/d/1wy14oi with 4x4x4x4 bifurcation (supposedly)
2018-11-09 23:03:31
Rotonen
i’m still avoiding from even recommending motherboards as there is no clarity on a cheap do-it-all board
2018-11-09 23:09:15
Fireduck
$400 is a lot. Hard to build cheap with one component being that high
2018-11-09 23:10:52
Fireduck
However, if these Intel cards do what they say you can load that guy up
2018-11-09 23:14:17
Rotonen
at that point it's cheaper to get multiple motherboards and processors already?
2018-11-09 23:15:17
Rotonen
or an actual 16x ssd?
