SMB v3 and the Multichannel feature was introduced to Server 2012 and allows for increased bandwidth simply by plugging more network cables into the switch from the same machine.

e.g. I added one quad NIC card each to my two servers, connected the cables to my switch and the bandwidth between the two servers jumped from 110MB/s ish (maxed out) to about 370MB/s. There is no HW support required on the switch - no teaming required; and no special configuration in Windows, it works out of the box.

The cost for the increase in bandwidth above was >£50.

The next step up to increase bandwidth between those two servers would be 10GBE which would be a minimum of £100 per NIC and £500 for the switch.

Although the cost of 10GBE is coming down all the time, it is still prohibitive for a significant number of users of FreeNAS.

Therefore, will/when will FreeNAS support SMB 3 and Multichannel to achieve this significant price/performance boon?

If/When Samba implements it. Experimental support was just added to 4.4. Not recommended for production.

There is already an ongoing thread here with people experimenting...
