2014 Gartner MQ Data Center Networking Arista Visionary Leader Arista best combination of Vision & Execution Arista only company to move up/right 2013-2014 Open and Programmable SDN platform for Datacenter Automation

Expectations within current data centers Always On expectation costs of downtime has skyrocketed and business SLAs has had to rise to keep pace Rise in data center Complexity with virtualization, multitier applications, and heterogeneous platform environments i.e. IT managers are struggling to get arms around the problem! Do more with Less tight resource constraints that hold IT budgets and headcount flat Business Agility quick time to market is key factor for maintaining competitive advantage

What is data center Automation?

Simply put Data Center Automation: is: automating changes which occur predictably and frequently, which would otherwise have been done manually!

Daily Jobs in Datacenter 10 Years Ago Systems Admin Network Admin

How about Systems Admin nowadays?

How about Network Admin nowadays?

Can Network Admin have a better life?

What is a Network device? L2 switching, VLAN, Trunk, STP, LACP L3 routing, IP, OSPF, BGP, PIM multicast OK other than that It s a Linux server with many NICs too Can we apply the beauties from servers to networks?

Automatic Network Topology Monitor and Report Topology and Config Template Various proactive types of alerts can be generated here based on network device connectivity: ZTP server Topology validation once ZTP process finish by LLDP checking against the defined diagram Proactive Alerting If there is ever a change in any or a key Route (e.g. OSPF, BGP, RIP, ISIS) / ARP / Mac-address, then the switch can send out a proactive alert to a centralized Syslog server notifying of the event LLDP Route changes / ARP changes / Mac address Change Management Once a network change has been complete, the switch automatically sends a Syslog server all the changes to (route / arp / mac) with the details of the engineer making the change Nightly report At the end of each day, a scheduled job can be run per network device listing all the (route / arp / mac) changes that occurred in the day

Talk to your network using IM ichat

One to Many: Grouping Changes, Config Rollback & Roll forward, Troubleshooting XMPP based Cloud Vision Server Management Server Devices are categorized in groups depending on topology Group A Group B Using a single CLI, the change control configuration can be rolled out from 0s to 000s of devices in the infrastructure Keep the last 50 configurations locally on the flash with a date, timestamp. If the user wants to be able to rollback to a previous configuration file, it is simple to do a diff on the current configuration and then roll the config back to a previous version if need be In the event of a network incident, instead of ssh or telnet into each device individually, using Arista s cloud vision server you can log into a GROUP of device and issue a single command eg to find an ip address and get the response back quickly
