Multipathing Storage Support in Apple macOS

[FlyerKumar]

Does Apple still support multipathing as indicated in this Technical Note TN2173: Multipathing with FibreChannel on Mac OS X on the Apple website, in the current versions of Apple macOS and if not, when (what version of Apple Mac OS X or macOS) was it removed or discontinued?

Was it only implemented only for Fibre Channel (and that too only for the Apple Fibre Channel cards which presumably were made for Apple by then-LSI Logic, now since part of Broadcom, or any Fibre Channel HBA?) or was it implemented for (or compatible with) SAS (Serial Attached SCSI) as well given that all SAS drives are dual-ported and support multipathing for redundancy and redundant paths to access them in addition wide-port mode for additional bandwidth?

If it still exists in currency versions of macOS, does it support only Fibre Channel or does it also apply to and support SAS HBAs and/or RAID controllers?

How would one access the macOS interface for it? Is there a GUI in macOS to access the multipathing settings or is there a terminal utility or set of terminal commands to view the status and settings and/or to configure it in macOS?

Does Apple still support multipathing...

Even though the article your are referencing is over 17 years old, Atto still supports multipathing on the Macintosh. But you would have to contact them for details.

I am aware of ATTO Multipath Director and have had many conversations with ATTO technical support in general recently regarding multipathing as well as this, but it supports Fibre Channel HBAs and not SAS HBAs or hardware RAID controllers (nor do they make hardware RAID controllers of an kind anymore).

There's a fair bit of information on that I thought you can read here:

Multipath TCP - Wikipedia

en.wikipedia.org

There might be some more info available on some of Apple's Developer Pages as well.

I am referring to storage multipathing via SAS and Fibre Channel, not TCP/IP or Wi-Fi or LAN multipathing.

According to this discussion at Apple: SCSI Port - Last Macs to Have? Rent in Ch… - Apple Community

the last time Apple had a SCSI interface was in 1999. I would seriously doubt that Apple still supports Multipathing via SAS 24 years later.
