Podcast#117: Fibre Channel Still Tops for Virtualization

Podcast Archive - StorageReview.com

Brian invited his friend Nishant Lodha, Marvell’s Director of Emerging Technologies to sit for the podcast. Nishant has been with Marvell for over 13 years. His key responsibilities include subject matter expert, technology evangelist, driving growth in emerging markets, competitive analysis, product positioning, outbound marketing, and hands-on technology analysis.

Nishant has worked with StorageReview on several topics, most recently on Innovation and Reliability Make Fibre Channel the Choice for Data Center SANs. Nishant strongly believes that Fibre Channel is the best solution for SAN deployment, and he is not alone. Look to other vendors, and they will echo his thoughts (although maybe not as loudly).

This is an excellent discussion about SAN technology, where it is, and where it is going. It is worth the 45 minutes, but the time stamp is below if you need to jump around in the video.

00:00 Introduction

• Candid introduction
• VMware vSphere integration
