RAMCloud Talk by Nandu Jayakumar @HortonWorks

Come hear me speak to the Hadoop guys at HortonWorks about my research at Stanford.

————————————

Abstract-

In recent years DRAM has played an increasingly larger role in storage systems, driven by the demands of large-scale Web applications. However, DRAM is still used primarily in limited or special-purpose ways, such as a cache for some other backing store. In this talk I will describe RAMCloud, a general-purpose storage system where all data lives in DRAM at all times and large-scale systems are created by aggregating the main memories of thousands of commodity servers. RAMCloud provides durable and available DRAM-based storage for the same cost as volatile caches, and it offers performance 10-100x faster than existing storage systems. By combining low latency and large scale, RAMCloud will enable a new class of applications that manipulate large datasets more intensively than has ever been possible.

Nandu Jayakumar was a Master’s student in the Computer Science department at Stanford University until recently. Before jumping headlong into online storage systems as a student, he mostly worked with batch-oriented storage systems at Yahoo.

Featured at Microsoft’s SQL Server conference – Yahoo’s mongo OLAP cube

I am going to be with the Yahoo data gang at this conference (sqlpass 2012) this year.

Microsoft’s Denny Lee is talking about the Yahoo use case – the largest SSAS data cube in the world!

Leaving Stanford……

Three quarters and a month later, it is time to leave the university. My masters program is now complete.

I moved out of campus during Summer itself. I am going to miss this place. My time here has been hectic but fulfilling in so many ways.

My master’s research report “Benchmarking Data Access in RAMCloud” is at  http://www.stanford.edu/~nandu/MS-research-report.pdf

SEDCL research retreat

The Stanford Experimental Data Center Lab had its annual research retreat at the beautiful Cavallo Point in Sausalito this year.

Among the many interesting presentations scheduled for June 3/4, I presented performance measurements made on RAMCloud so far. See Nandu – System performance measurements for the slides.

It was a great opportunity to meet the SEDCL afficiliates. We had very interesting conversations with the Mellanox engineers about the behavior we were seeing on their networking gear.
