Applications are Driving Traffic Patterns in Cloud Networking

As we enter the second half of 2010, I sense that an architectural shift in data center environments has begun replacing traditional constructs. Traffic Patterns are rapidly shifting from the traditional North-South client server model to an East-West server to server. As this shift occurs, it is even more important to assess the impact of application…

The Power of Cloud Networking

The future of data centers is changing rapidly. Enterprise data centers are no more about basic networking connectivity where networking was driven mostly by client-server applications such as email and web at 1Gigabit Ethernet connectivity with 10% utilization. The data center world is getting better, faster and is demanding a wire speed network approach for…

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…
