SysDB has state awareness for each process, and can even restart a process
automatically

Arista is located in Santa Clara CA in the heart of silicon valley. It was founded by Andy Bechtolshiem and David Cheriton. David Cheriton is currently a professor at Stanford university. Andy was a co-founder of sun Microsystems in 1982. Andy and David co-founded a company called granite systems in 1995 which was subsequently acquired by Cisco systems in 1996. Andy served at VP and GM of Cisco’s Gigabit Systems business unit from 1996 to 2003. The gigabit Systems business unit was responsible for the highly successful Catalyst 4500 and 4900 Series of switches. Andy and David were also the initial investors in Google in the late 90s
Jayshree Ullal, formerly SVP of Cisco’s Data Center, Switching and Services group was named Arista’s CEO in 2008. A 15 year veteran of Cisco, Jayshree originally came to Cisco through their first acquisition of Cresendo in 1993.
The market leader had a “silo” approach (different infrastructures for different applications) which was over-engineered, too complex, too expensive, too rigid, and prone to software deficiencies (excessive bugs requiring restarts, patches or upgrades)
Customers demanded higher value and reliability. Better automation, standardization, and programmability. In short: Next-generation data centers required a new hardware and software architecture.
Network virtualization is all about the overlay, we’re are the underlay, which is the foundation for any virtualized network or service. In fact, when the President of Vmware came to speak at Arista, he coined the phrase: “Software doesn’t run on Software”
This switch is the heart (and the Spine) of the two largest networks in the world (Netflix)
The largest buffers in the industry – when performance really matters. Competitive switches have 9 MB (buffering), we have 9 GB. 1000x
