PCIe bifurcation to split an x16 or x8 slot into multiple x4 channels: allows PCIe adapters with multiple NVMe cars

Posted by jpluimers on 2022/03/07

It looks like some X9 and X10 Supermicro boards already support PCIe bifurcation (splitting of PCIe slots into multiple channels), which might be worth a try to upgrade some of my older rigs to use NVMe instead of SATA storage as it will allow me to use adapters that support multiple NVMe devices into a single PCIe slot.

The X9 motherboards uses an LGA 2011-R socket, and the X10 motherboards an LGA 2011-R3 sockets.

Both use chipsets not being that different: the X9 uses the C600 series (which are similar to the X79 consumer series), and the X10 uses the C610 series (which are similar to the X99 consumer series).

This is what I found out about the bifurcation support for my boards:

MemTest86 for MBR booting systems: use the really old version 4.3

Posted by jpluimers on 2022/03/02

Sometimes you come across old systems that do not support UEFI booting, so for memory testing you need tools that either are embedded on something like a Linux image that os in MBR, or the plain ISO download of older versions.

I opted for the latest “older” version 4.3 of MemTest86 [Wayback]:

As MemTest86 V9 supports only the newer UEFI platform, older PCs without UEFI support would be unable to boot MemTest86. In order to run MemTest86, PCs with legacy BIOS platform must use the older V4 release of MemTest86. The download links for the V4 downloads are still provided for those that prefer to work with the V4 bootable images.

V4 Windows Downloads: Download

A few ways to reset a Samsung MU6100 55″ TV

Posted by jpluimers on 2022/02/18

Some interesting tidbits to reset a UE55MU6100 or similar TV from [Wayback/Archive.is] We have a 2 week old Samsung mu6100 55″ tv which up until an:

  • Soft reset: Unplug the TV from the wall, hold down the power button on the rear of the TV for 10 seconds, then plug it back in and turn it on.
    • The power button is on the backside : it’s the middle part of the 4-arrow-button.
  • Factory reset: power off the TV, and hold down up, down and power buttons together for about 10 seconds, then releasing them when the Samsung Logo shows up.
  • Reset to engineer menu: put the TV in standby, then press the info, menu, mute and power buttons on the remote

Samsung 980 Pro NVMe SSD serial in ESXi is in different byte order than the sticker

Posted by jpluimers on 2022/02/03

I installed three Samsung 980 Pro NVMe SSD devices in various ESXi rigs.

This is the serial numbers that ESXi came up with:

  1. Local NVMe Disk (t10.NVMe____Samsung_SSD_980_PRO_1TB_________________E824B311B1382500)
  2. Local NVMe Disk (t10.NVMe____Samsung_SSD_980_PRO_1TB_________________782DB311B1382500)
  3. Local NVMe Disk (t10.NVMe____Samsung_SSD_980_PRO_1TB_________________6F2DB311B1382500)

ESXi presents the serial number (actually the EUI64) in reverse byte order of what is on the device labels.

I had to look up what EUI64 was, and it is a kind of UUID (see Universally unique identifier – Wikipedia), but for hardware devices:

  • World Wide Name – WikipediaEach WWN is an 8- or 16-byte number, the length and format of which is determined by the most significant four bits, which are referred to as an NAA (Network Address Authority). The remainder of the value is derived from an IEEE OUI (or from Company Id (CID)) and vendor-supplied information. Each format defines a different way to arrange and/or interpret these components. OUIs are used with the U/L and multicast bits zeroed, or sometimes even omitted (and assumed zero). Though CID has U/L set to 1.The WWN formats include:…
    • “Mapped EUI-64” formats manage to fit an EUI-64 address into an 8-byte WWN. Since the NAA is mandatory, and takes up a nibble, this represents a four-bit deficit. These four bits are recouped through the following tricks: First, two bits are stolen from the NAA by allocating NAAs 12, 13, 14, and 15 to all refer to the same format. Second, the remaining two bits are recouped by omitting the U/L and multicast bits from the EUI-64’s OUI. When reconstructing the embedded EUI-64 value, the U/L and multicast bits are assumed to have carried zero values.

    …

  • [Wayback] Base NVM Express – Part One – NVM Express

    A namespace ID (NSID) is an identifier used by a controller to provide access to a namespace (handle to a namespace). An NVMe controller may support multiple namespaces that are referenced using NSID. EUI64 (8 bytes), NGUID (16 bytes) and UUID (128-bit) are globally unique namespace identifiers defined in the Base Specification.

  • [Wayback] VMware Docs: NVMe Devices with NGUID Device Identifiers

    For NVMe devices, ESXi generates device identifiers based on the information it retrieves from the devices. Generally, the NVMe devices support identifiers in EUI64 or NGUID formats, or use both formats. NGUID is a Namespace Globally Unique Identifier that uses the EUI64 16-byte designator format.

  • [Wayback] ESXI6.7 nvme ssd issue – VMware Technology Network VMTN

    Being a software engineer, I am disturbing by the way this software create the disk ID.

    According to the following table from VMware Docs we have some case that the software will not recognize the disk or lost disks.

    ID Formats Supported by Device Device Identifier Generated by Host
    EUI64 ID Format NGUID ID Format ESXi 6.7 and earlier ESXi 6.7 Update 2
    yes yes t10.xxx_EUI64 t10.xxx_EUI64
    yes no t10.xxx_EUI64 t10.xxx_EUI64
    no yes t10.xxx_controller_serial_number eui.xxx (NGUID) as primary ID

    t10.xxx_controller_serial_number as alternative primary ID

    so what if

    1. The NVMe SSD from the same company may use the same EUI64 for every NVMe SSD on the same interface (say using an ASUS Hyper M.2 X16 PCIe 3.0×4 Expansion card with 4 identical NVMe SSD). It is possible because of bad design from the SSD manufacturer, the EUI64 are all the same for the 4 NVMe SSD, under this case, the ESXI will only recognized one of the 4 disks (since the disk will be t10.xxx_EUI64, and EUI64 are the same for all 4 NVMe SSD, The “storage” “adapters” tab did show there are 4 interfaces (adapters), but the “stroage” “devices” will only show 1 disks.
    2. Why there is no “no, no” options?

    I understand that the NVMe standard 1.3 (for ESXi 6.7) is the base of how the NVMe SSD should be designed, but I think the software should be smart enough to cover the mistakes the hardware company may make and so it can recognized most of the NVMe SSD that is available from the market.

    …

    I have the same issue in V7.0! Whatever happened to using something you know is unique like serial numbers or something based off the serial number!

    My two identical NVMe drives show up as one! Very odd how this one got through testing!

    …

    Having same issue with the Asus hyper x16 m. 2 pcie card. I have 4 Intel 660p in it and it’s only showing 1. Even when I changed the bifurcation to x4x4x4x4 for that pcie slot. It actually show nothing. When in auto it shows 1. I’m using esxi 7 though. Trying to test out VMware horizon but esxi not detecting all the nvme in the Asus adapter.

  • [Wayback/Archive.is] linux.kernel: [PATCH 0/7] Implement NVMe Namespace Descriptor Identification

    This patchset implemets NVMe Namespace Descriptor Identification as of
    NVMe 1.3. The Namespace Descriptor Identification allows a NVMe host
    to query several Namespace Identification mechanisms, such as EUI-64,
    NGUID and UUID from the target. If more than one value is set by the
    target, it can transmit all set values to the host.

  • [Wayback] OS-6042: Need to handle NVMe devices with EUI64 values (SmartOS + ZFS)

  • [Wayback] ⚙ D19905 bhyve: Add EUI64 to NVMe device (FreeBSD)

    Add the EUI64 field (part of the Identify Namespace data) to NVMe devices to support UEFI drivers.

    The implementation will accept an IEEE Extended Unique Identifier (EUI-64) from the command line. If one isn’t provided, it will create one based on

    • The IEEE OUI reported in the Identify Controller data
    • The PCI bus, device/slot, function values
    • The Namespace ID
  • [Wayback] nvme-scsi: Use correct byte ordering for eui64 in Dev ID VPD – Patchwork
    NVME specifies an EUI64/NGUID in little-endian format, while SCSI
specifies that the Device Identification VPD use big-endian for EUI
formats. The current code copies this bytestream directly from the
Identification Namespace page, meaning we just need to reverse the
bytestream when passing it on to the VPD.

    …

    This seems to hold true for NGUID devices, but Keith just pointed out to
me that it may not hold true for EUI64 devices. It seems like that case
needs byte swiveling within each field. So I'll NAK for now until I can
figure out if that's the case.

    …

    This will break existing setups that rely on VPD 0x83 for device
identification (which I think includes older SuSE distros).

And once you change the setup anyway please stop using this buggy
SCSI emulation.

Some links on using and updating Let’s Encrypt certificates for internal servers

Posted by jpluimers on 2022/02/01

Sometimes it is easier to have current and public CA signed TLS certificates for internal servers than to setup and maintain an internal CA and register it on all affected browsers (including mobile phones).

One of my reasons to investigate this is that Chrome refuses to save credentials on servers that have no verifiable TLS certificate, see my post Some links on Chrome not prompting to save passwords (when Firefox and Safari do) about a week ago.

Below are some links for my link archive that hopefully will allow me to do this with Let’s Encrypt (msot via [Wayback/Archive] letsencrypt for internal servers – Google Search):

Fritz!Box and mobile USB sticks (Huawei E3372; 4G Systems W1208): some links; hopefully later also some personal experience

Posted by jpluimers on 2022/01/27

There seem to be at least three Huawei E3372 models:

  • Huawei E3372s
  • Huawei E3372h-153
  • Huawei E3372-h-320

4G Systems W1208 seems to have only one model (it is an OEM Huawei E3372, not sure which submodel), but it looks like it is only available in Germany, and might even be region locked.

There are various reports on which ones work/fail with Fritz!Box devices as backup-internet link.

    I just tested using VoIP when using the USB Mobile data on the E3372 dongle on the 7590 (Optus pre-paid mobile data plan). I was able to call out on VoIP to my mobile. I suppose incoming VoIP call would also work…

    …

    The secret to getting VOIP to work over a mobile connection is to set the Transport Protocol in the FritzBox to TCP. You thus need a telephony provider that supports TCP.
    I’ve tested my 7590 (running FritzOS 7.20 or later) and an E3372 (using Optus) with SipTalk, and it worked correctly.
    You’ll find the setting under Telephone number, Edit, Additional Settings for the Connection, Transport protocol. Other needed settings are: Username, Password and Registrar. You can leave Proxy and Stun servers blank.

  • [Wayback] Fritz!Box 7490 und Huawei E3372 für Internet | IP Phone Forum

    …

    Hallo, ich habe F!B 7490 international, habe Huawei E3372.USB LTE Stick mit o2.de SIM angeschlossen. LTE Internetverbindung funktioniert perfekt mit APN “internet”.
    Zuerst habe ich E3372 im Tethering mode an der F!B 7490i betrieben und konnte ich auf Hilink zugreifen.
    Da ich aber die native IP adresse benutzen wollte, habe
    habe ich die E3372 als Modem angeschlossen. Internet mit APN “internet” funktioniert weiterhin perfekt. Bekomme eine private native IP adresse an der F!B 7490i.
    Bei O2.de habe ich mir für SIM-Karte eine öffentliche IP adresse geben lassen. Dazu muste ich den APN auf “netpublic” umstellen.
    Jetzt kommt die Internetverbindung nicht zu stande. F!B zeigt unter ‘Mobilfunk’ dass das Netz gefunden wurde ‘bereit’ aber SIM ist nicht registriert wurde.
    Im Modem Mode kann ich über Hilink auf die Konfiguratioin der E3372 nicht zugreifen.
    Die SIM Karte in einem anderen Router (TP-Link M7350) funktioniert die SIM Karte mit APN “netpublic” mit öffentliche IP adresse eiwandfrei.
    Zurück zu F!B 7490i mit E3372 als Modem und APN “netpublic”.
    Bis jetzt keine Hilfestellung von AVM.
    Bin dabei das Problem mit F!B 7490i zu lösen.

    …

    Mit aktueller 7.12-DE-FW scheinen die Sticks den Tethering-Mode nicht mehr (ohne weiteres?) zu beherrschen und werden trotz-HiLink-FW (22….) trotzdem ausschließlich als Modem angesprochen bzw. umgeschaltet.
    Vormals -bei älterer FW <7.xx … iirc- hing die Einbindung/Erkennung entweder als Modem oder Tethering-Device allein von der FW des 3372-Sticks ab (22er versus 21er-Version). Umso erstaunter bin ich über die eingangs zitierte Aussage, dass Du dies anscheinend wohl nach Belieben steuern könntest? Über das “how” wäre sicherlich mancher Leser hoch erfreut.
    Zu Deinem Problem: Es könnte sein, dass im Modem-Mode auf vorgefertigte APN-Listen zurückgegriffen wird, die eben “netpublic” (noch) nicht kennen und eine diesbzgl. Änderung im FB-GUI gleichfalls nicht greift? Die FW des 3372 ist eh schon recht betagt, sodass dieser intern die Verschmelzung von E-Plus und O² wohl auch noch nicht vollständig mitbekommen hat.

    …

    Habe ich vom AVM den gleichen Typ erhalten wie Du beschreibst, es lag genau an dem dass ich ein neues Profil mit APN “netpublic” einrichten mußte. Jetzt funktioniert die F!B 7490i mit E3372 und APN “netpublic” tadenlos.
    Hier noch die Angaben zu E3372h und F!B 7490i.

Außerdem könnte es Nutzer dazu bringen, kein Update mehr zu machen, wenn ein Feature weg gekürzt wird, dass sie früher einwandfrei genutzt haben… :/

    An meiner 7490 hängt ein Huawei E3372 und macht was er soll. Einen Anschluss für eine externe Antenne hat er auch.

    …

    In einer FB7490 FW 7.19-81587 (inhaus) erkenne ich im Bereich “Netzverfügbarkeit” 2von5 Balken … im Telekom-Mobilfunknetz hier indoor.
    Auch wenn ich nicht stündlich/täglich Ooaklo-Speedtests versuche, komme ich eher regelmäßig/ohne Probleme “eingebremst auf tarifliche 50/10MBit/s” auf die Werte.

    …

    Generell habe ich unmaßgeblich erkannt, dass die E3372s oder h erheblich “wärmer” werden im Betrieb als der W1208. Ein Blick auf das Konstruktionsdatum E3372 ca. 2005/2006 lt. FW der W1208 laut “Bepper” 18/8/2019 könnte doch einen markanten Hinweis liefern, womit man besser fährt?

    …

    Habe mir nun einen gebrauchten W1208 von 4GSystems (1und1) geholt und der läuft.

    Ok jetzt hab ich es nochmal versucht und plötzlich wie von selbst wird der Stick korrekt erkannt auch an der 7590.

  • [Wayback] FritBox 7490 und Huawei E3372h-153 – kein No-HiLink? | IP Phone Forum

    In Bezug auf den E3372s/h ist es als Backup-Lösung unerheblich, ob dieser als als usb-net Device (HiLink-FW) oder usb-modem (NoHilink-FW) arbeitet. Dies ist ausschließlich von der verwandten SIM (Tarif/Netz/Lokaler Empfang) abhängig. Gerade bei O² (Netzkonsolodierung mit Base/E-Plus) kann es lokal sinnvoller sein, sich im 3G-Modus zu bewegen statt 4G.

    Damit ein usb-modem -hier ein E3372 mit NonHilink- vollständig und korrekt eingebunden wird, muss als Inet-verbindung eben der Client-Modus (hier hinter Kabelmodem) erst verlassen werden und “voll” über Mobilfunkverbindung kurz eingerichtet werden.

    -Dies gilt auch für andere voicefähige UMTS-Sticks z.B. für die GSM-Gateway-Geschichte-

    Danach kann man wieder auf Client-Modus umschalten. -hier I-Net via LAN1 und Kabelmodem-

    …

    In Verbindung bzw. dem Einsatz an einer FB7490 ist dies -aus meiner persönlichen Sichtweise heraus- nicht einfach zu beantworten, da es oftmals auch an der verwandten SIM-Karte liegt und eben der gebuchten Geschwindigkeit nebst den Empfangsverhältnissen. Oftmals kommt die Kombination eher stationär auf Campingplatz/Gartenlaube/Ferienwohnung o.ä. zum Einsatz, wo jeder dies halt persönlich Testen muss, was im Dauereinsatz stabiler läuft.
    Erschwerend kommt hinzu, dass laut aktueller 7490 Intern-/Labor-FWs sich einiges tut in der Anbindung, da wohl Anpassungen im Rahmen der FB6890, die eben ein UMTS/LTE-Device schon onboard hat, ins Haus stehen. Da es keine Voicefähige FW für den E3372 gibt, kann man durchaus bei einer HiLink-FW bleiben. In Verbindung mit anderen Routern auf Linux-Basis, ist die Anbindung -lt. Tenor im lteforum.at- mit der NonHiLink-FW stabiler.

    Und wo wir schon dabei sind: was ist der Unterschied zwischen dem E3372s und E3372h?

    Es handelt sich nach meinen Wissen um unterschiedliche Hardware-Revisionen. Bekannt ist allerdings, dass die h-Version inpunkto Umflashen recht zickig sein kann, und es wohl öfters schon zu gebrickten Sticks dabei kam/kommt und man mit der “Nadel-Methode” und Spezialtools diese eher mühsam wiederbeleben muss/kann.

Some links on Chrome not prompting to save passwords (when Firefox and Safari do)

Posted by jpluimers on 2022/01/20

For quite some time now, Chrome (think years) refuses to prompt for saving passwords whereas Firefox and Safari do prompt and save them, even for site types that it used to save passwords for in the past.

It has been annoying enough for too long now that I tried to do better than the Google searches I used back when I saw this happen first.

Below are some links based on new searches (starting with [Wayback] adding a password in chrome settings – Google Search); hopefully I can try them after I made a list of sites that Chrome does not show the password save prompt for.

Solutions I tried that failed (but maybe useful for others):

Solutions still to try:

Some notes on OKI memory modules and toner cartridges for MC342 / C332, as toner cartridges physically seem compatible, but are not

Posted by jpluimers on 2022/01/14

I thought the C332 had the same engine as the MC342, as internally the printing part looks identical.

Boy, I was wrong. Toner cartridges, though fitting physically, are not compatible, despite having the same image drum part 44968301.

So the MC342 and C332 have different toners that are physically so similar that they fit, but electronically different.

While searching, I found the C332 by default has 1 gigabyte of memory and no upgrade option, but the MC342 only has 256 megabyte of memory and can be upgraded with one 512 megabyte module to 768 megabyte. This improves printing performance considerably.

The memory module part number is 01182908, which is horrendously expensive despite it being a PC4200 DDR2 SO-DIMM, which means PC5300 and higher should also work.

Historically between EUR 100 and EUR 350 ([Wayback] Oki 01182908 – Prijzen – Tweakers) or GBP 250 ([WayBack] OKI 512MB RAM Memory Upgrade for B721, B731, B840, C321, C330, C530, C531, C610, C612, C711, C712, C822, C823, C831, C833, C841, C843, MC332, MC342, MC351, MC352, MC361, MC362, MC561, MC562 printers)

So via [Archive.is] 512mb ddr2 sodimm – veilingkijker – nieuw en tweedehands I found [Wayback] ≥ Apple 512mb DDR2 667MHz SODIMM – Geheugens – Marktplaats.nl and tried it.

MC342 toner in C332 printer

As soon as you put a black MC342 toner in a C332 toner, you will get this error in the display: SERVICE CALL 231:ERROR 08 (see picture and [Wayback/Archive.is] oki service call 231 error 08 – Google Search)

This error only goes away when:

  1. you re-insert the original toner cartridge
  2. then power-down and power-up the printer

I could not find C332 specific information for this error, but similar models do have it (partially) listed (note the 08 error for the C332 means the black toner cartridge, not the cyan one):

[Wayback] Valetudo | Cloud-free control webinterface for vacuum robots

Valetudo is a standalone binary which runs on rooted Vacuums of the Xiaomi ecosystem and aims to enable the user to operate the robot vacuum without any Cloud Connection whatsoever.

You can even use it to make a WiFi heat map of the floors in your home: the Valeroni app can do that for you.

The Valeroni app is open source too: [Wayback/Archive.is] ccoors/Valeronoi: A WiFi mapping companion app for Valetudo
