"Merchant silicon will be used for basic Layer 2 switching, Layer 3 routing and VXLAN overlay, while the Insieme ASIC will be used for buffering, virtual output queuing and VXLAN routing. ACI will be founded on VXLAN, with Insieme hooks in the VXLAN header for additional application identification and traffic classification. Within each VXLAN, traffic can be classified and policies applied to millions of applications, sources say."
"The first release of the Nexus 9000 will operate on Broadcom's Trident 2, Titan and HiGig2 chipsets -- three Trident 2's will connect a Nexus 9000 line card to the Titan fabric using HiGig2 interfaces. The Nexus 9000 will initially be optimized for high-density 40G Ethernet applications, not 100G. At first release, the eight-slot switch will support 288 40G ports."
"Insieme is struggling to design the chips for the new product, a source told us. Insieme's custom chips, called ASICs, are so far behind schedule that Cisco is going to have to use standard off-the-shelf chips from chip maker Broadcom in its first-generation SDN device, 'the same as everyone else,' our source told us.
"Cisco confirmed part of this, but said the plan was always to build its first device using standard chips, also called 'merchant silicon.'
"We also learned that the software used by Insieme will be homegrown and based on a version of the operating system Cisco uses in its Nexus switches, NX-OS, our source said. That means it won't be an adaptation of the open source software known as OpenFlow created by Nicira's founders, and it should work well with Cisco's current products."
An unconfirmed rumor suggests that Cisco's about to announce the Insieme NetworksNexus 9000 which uses Broadcom Trident 2 - not internal Cisco Silicon because Cisco's Silicon just can't keep up.
Furthermore, unconfirmed rumor suggests that the Nexus 7700 is about to be announced with:
Straight-thru airflow, 2.2Tb/slot.
No support for any existing modules.
Will ship with an updated F2 module.
F3 module within 6 months - probably 20-24 40Gb ports.
