Introduced Nov 16, 2016
Qumran backfills behind Jericho that was introduced in 2015.
Qumran is a single chip version of Jericho. It has not intended to connect to a backplane crossbar switch -- and hence single chip. Its place in the hierarchy is to fill the deep buffer top-of-rack requirement. It's big brother Jericho is intended for a chassis environment where each line card gets a Jericho and there is a crossbar switch in the backplane. Some fixed form factor switches contain two Jericho ASICs directly connected through their crossbar interfaces in a 1 RU package so you can't tell the internals from looking at the package alone.
Three sizes of Qumram have been announced by Broadcom -- variously refered to as Papa Bear MX, Mama Bear AX, Baby Bear UX.
Update Sept 2019
|At the September 2019 regional OCP conference Carsten Michel (Deutsche Telekom) presented on new switches designed to fill the BNG (border Network Gateway) slot. These switches -- one leaf, one spine -- will use the Qumran 2C when it becomes available. Meanwhile, Delta is building prototypes with the Jericho 2C which is a pin-for-pin equivalent except that the latter has a fabric interface that is not needed here.|
