Announcement date of this Cavium Xpliant based switch: December 6, 2016.
The release is one day after Arista announced their 7160 products. Brocade also released the SLX-9540 at the same time. If Networking had an annual award for cliche ridden product information that at the same time manages to keep actual content to a bare minimum, the contest would already be over for this year.
