Connectors/cables for Serial Attached SCSI and SATA – Wikipedia

Posted by jpluimers on 2021/05/10

Since I always get confused with SAS and SATA connectors, some tables from Wikipedia:

  • Serial Attached SCSI Connectors- Wikipedia
    Codename Other names Ext./int. Pins No of devices / lanes Comment Image
    SFF-8086 Internal mini-SAS, internal mSAS Internal 26 4 This is a less common implementation of SFF-8087 than the 36-circuit version. The fewer positions is enabled by it not supporting sidebands. SFF 8086.jpg
    SFF-8087 Internal mini-SAS, internal mSAS, internal iSAS, internal iPass Internal 36 4 Unshielded 36-circuit implementation of SFF-8086. Molex iPass reduced width internal 4× connector, 12 Gbit/s capability. SFF-8087 SMC.jpg
    SFF-8088 External mini-SAS, external mSAS, external iSAS, external iPass External 26 4 Shielded 26-circuit implementation of SFF-8086. Molex iPass reduced width external 4× connector, 12 Gbit/s capability. SFF 8088.jpg
    SFF-8470 InfiniBandCX4 connector, Molex LaneLink External 34 4 High-density external connector (also used as an internal connector). SFF 8470.jpg
    SFF-8482 Internal 29 2 lanes This form factor is designed for compatibility with SATA but can drive a SAS device. A SAS controller can control SATA drives, but a SATA controller cannot control SAS drives. SFF-8482 SAS Plug - Bokeh at f22.jpg
    SFF-8484 Internal 32 or 19 4 or 2 High-density internal connector, 2 and 4 lane versions are defined by the SFF standard. SFF-8484 straight connector.jpg
    SFF-8485 Defines SGPIO (extension of SFF 8484), a serial link protocol used usually for LED indicators.
    SFF-8613 (SFF-8643) Internal 36 4 or 8 with dual connector Mini-SAS HD (introduced with SAS 12 Gbit/s) SFF-8643 SMC.jpg
    SFF-8614 (SFF-8644) External 4 or 8 with dual connector Mini-SAS HD (introduced with SAS 12 Gbit/s) SFF-8644 cable.jpg
    Sideband connector Internal Often seen with 1× SFF-8643 or 1× SFF-8087 on the other end – internal fan-out for 4× SATA drives. Connects the controller to drives without backplane or to the (SATA) backplane and optionally, to the status LEDs. Sideband.jpg

    • A seven-pin SATA data cable (left-angled version of the connector)

    • SATA connector on a 3.5-inch hard drive, with data pins on the left and power pins on the right. The two different pin lengths ensure a specific mating order; the longer lengths are ground pins and make contact first.

SC732D4-500B | Mid-tower | Chassis | Products | Super Micro Computer, Inc.

Posted by jpluimers on 2021/05/10

The [WayBack] SC732D4-500B | Mid-tower | Chassis | Products | Super Micro Computer, Inc. is a nice tower case, but remember that it has 2 USB 3.0 ports on the outside.

If you have a motherboard without onboard USB 3.0 pin headers, or one with incompatible pin headers, then you cannot use these ports with this standard cable that comes with the case:

Cable(S) CBL-0453L 1 USB 3.0,INT,19 PIN/F TO 19PIN/F,60CM,CONNECT TO CBL-0454L

Most of the X9 motherboards have no compatible pin headers.

These boards are an exception:

Too bad my boards are X9SRI-F and X9SRI-3F (do NOT get the bare X9SRI: it has no iPMI) with C6xx Dual processor Sandy Bridge-based Xeon chipsets (List of Intel Xeon chipsets) – Wikipedia:

This cable might fix this, though there is very little documentation on either of these cables:

Adapter Cable CBL-0454L USB3.0 to 2.0 adapter cable – 30cm(19pin male to 9pin female)

I could find no site with a picture of the first cable, and only newegg had pictures of the last one.

[WayBack] Supermicro CBL-0454L Supermicro CBL-0454L USB 3.0 to USB 2.0 Adapter Cable – Newegg.com

Luckily I had an X10 manual at hand, so here you can see the various pin-outs.

One end of the CBL-0454L has the same pin out as “USB (3.0) USB#11 Pin Definitions” (actually you need to double the rows) so CBL-0453L fits into it.

The other end of CBL-0454L fits into “Front Panel USB (2.0) #4/5, 6/7, 8/9” headers.

Fitting 2.5 inch drives in it

Another interesting aspect is part:

2.5″ HDD Bracket MCP-220-73201-0N HDD Cage (4x Internal 2.5″ fixed HDD bays)

Again hard to find pictures. There is only one at the whole supermicro site:

The part is [WayBack] Supermicro MCP-220-73201-0N Accessories with 0091016_2-5in-hdd-cage-4x-internal-2-5in-hdd.jpg (500×500)

Supermicro X9SRi-F Mainboard with SCU – Motherboards and CPUs – Unraid

Posted by jpluimers on 2021/05/10

Passthrough should work with these: [WayBack] Supermicro X9SRi-F Mainboard with SCU – Motherboards and CPUs – Unraid

Both unRaid and eESXi success in that thread.
