Intro aprox March 2016. Seems late, for a 10 Gig switch. Tolly report released in June, 2016 seems to indicate that this is a strategic product. At least, they spent money on it. There is an information sheet. To Extreme's credit, packet buffer is listed. This swith is selling at newegg, mac-Connection, eBay, Amazon. It seems to be geared as a small 10G server hub. Street price for 16 ports is $3K in june 2016.
