Is 2010 the Year of 10Gig?

As 2010 begins and we celebrate the onset of the next new decade, I would like to wish my readers a happy new year and also pose a question asked many times before. Will 10 Gigabit Ethernet (10GbE) reach the inflection point in the datacenter this year? A number of analysts believe 2010 is watershed…

Scalable Techniques for Multi-terabit Cloud Networking

Current data center network designs are very compromised. They are based on blocking multi-tier designs with 50:1 over-subscription using the Spanning Tree Protocol (STP) to prevent loops and enable device redundancy. Link Aggregation, LAG, was introduced to distribute network traffic across multiple links for more capacity. This made scalable bandwidth and device redundancy mutually exclusive….

Celebrating our first year!

This month we are celebrating our first year as Arista Networks. We re-launched last year with our new name, our management team, and global availability of the Arista 71XX series for the 10 gigabit Ethernet market. As I reflect back on the past year, there are many milestones to celebrate despite the economic downturn and…

Virtualization & Cloud Networking: Connecting the Dots….

As we enter VMWorld I would like to explain this further and showcase Arista’s thought leadership. The widespread deployment of server virtualization has created a ripple effect on network deployments. Each physical server now has multiple virtual images with their own MAC address. The deployment of virtual soft switches such as VMware’s vNetwork Distributed Switch…

Virtualization & Clouds – Are they related?

Frequently, I am asked about the relationship between Virtualization and Clouds. In one word, the answer is “yes”, they are related. They are symbiotic cousins. They can exist separately, but together place greater demands on re-designing networks.Virtualization technologies from VMWare, Citrix and Microsoft have created exponential server and network increase. A direct consequence of virtual…

Citrix and Arista – Two Pioneers Partner in Cloud Networking

Today’s Datacenters are still separated distinctly by OSI stack layers. Layer 2/3/4 switching are typically implemented by 1/10GE switches and application delivery functions such as L4-L7 server load balancing are deployed as appliance functions largely as two ships in the night. In a cloud environment, a more “in-band” network deployment model, one that is highly…

Does Latency Matter in Cloud Networking?

Cloud Networking has arrived upon us. Take server density on a scale never seen before plus compute demanding application workloads and you get a class of non-blocking cloud networking that is more aware of dynamic application flows than vanilla packet switching. A key design criterion here is Latency. Of course there are differing views on…

Which Technology Will Prevail for Cloud Networking?

As we enter this new era of dense servers and multi-core cloud computing, one must pay closer attention to the choice of the right cloud networking technology for seamless compute, network and storage access. I find myself in the midst of “Ethernot vs. Ethernet” choices. Three candidates present themselves as viable options: 10 Gigabit Ethernet,…
