Arista 7500: A New Switch is Born!

In my networking career I have been involved in a few generations of switches spanning multiple decades. The goal has always been a next generation Ethernet speed transition; from 10/100 Megabit in the nineties to 1 Gigabit in the new millennium and now 10 Gigabit in the new decade. Each Ethernet speed transition saw the…

10 GbE is the no-brainer in Storage Networking

I am a big fan and proponent of iSCSI or NAS protocols over 10GbE for storage access. It is the workhorse and unsung hero in storage networking. Akin to ethernet’s simplicity, iSCSI protocol is ubiquitous, familiar and enables mainstream storage applications. iSCSI also enjoys the benefits associated with block-level shared storage combining Ethernet as the…

The race to zero latency in Cloud Networking

The goal is millions of transactions in real time. Not an easy feat without a new class of networking gear and new architectures. It is changing and challenging traditional constructs for High Frequency Trading (HFT) markets. It creates an insatiable appetite to shave every nanosecond of latency to overcome a long-standing barrier that has existed…

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…
