This is part two in a Q&A series with Panasas founder and CTO, Dr. Garth Gibson. He was recently asked by a large storage research center to comment on various HPC storage topics. Garth’s thoughts on solid state technology were captured in the following exchange.

Question: Solid state drives have given a renewed impetus to the development of cache solutions.  Both hardware and software solutions have been introduced to market.  Some examples are Fusion-IO’s IO-cache, LSI’s MegaRAID cache software, Adaptec’s MaxCache, Sanrad’s VXL software.  Of these, the first...

Over ten thousand (more than ever before) supercomputing enthusiasts, professionals, and scientific and technical computing users descended on Seattle last week for the HPC industry’s largest event of the year – Supercomputing 11 (SC11) to share their insights in a range of sessions and events.

Panasas was there in full force with our largest conference footprint ever. We demonstrated Panasas ActiveStor – the world’s fastest HPC storage system, and two partners – CD-adapco and...

This is part 1 in a Q&A series with Panasas founder and CTO, Dr. Garth Gibson. He was recently asked by a large storage research center to comment on various HPC storage topics. Garth’s thoughts on virtualization were captured in the following exchange.

Question: The current state of virtualization has rich functions and features for controlling and managing compute resources, and at the same time making progress in integrating with network resources management.  A key question is how much progress has been made and what are the features that are still lacking, or need to...

Visit us at Supercomputing 2011 (SC11), November 14 - 17, in Seattle, Washington, at the Washington State Convention Center, in booth #1506.

We are planning a lot of informative events for our customers, partners, prospects and the press – most notably, we would like to invite all interested show attendees to the Panasas breakfast; details are below. If you would like to request a meeting with Panasas, please follow the included link. We’ll see you there.

Panasas Award Nominations:

Panasas is pleased to have been nominated for three HPCwire Readers Choice Awards....

Analyst firm, Intersect360 Research, has released a new white paper, “Solving Big Data Problems with Private Cloud Storage,” in which it describes Panasas as well-positioned to provide storage solutions for HPC private storage clouds. The comprehensive paper explores the challenges that HPC applications face, making public clouds less attractive than private cloud implementations.  HPC big data applications with very high data-to-compute ratios are challenged in a public...

Over the last ten years, the HPC market has been transformed by the widespread adoption of compute clusters for technical computing workloads, accompanied by high growth rates in the generation of unstructured data. The storage industry has been responding by transitioning NAS architectures from old-school, legacy NAS to modern scale-out NAS approaches. Unsurprisingly, high performance computing has led the way in terms of requiring the most from scale-out products.

In the following slidecast I did for InsideHPC, I present some of the history behind scale-out NAS, and discuss how...

In my last post I talked about how the Panasas parallel file system (PanFS) achieves extreme performance for big data sets. It also provides redundancy without the need for hardware RAID controllers. In the attached video, Garth Gibson, Panasas founder and CTO, digs deep into the specifics of file system RAID and how PanFS delivers redundancy as part of the file system itself. He compares this innovative approach to most other parallel file systems which push...

In 2008 the first computer broke the petascale barrier, allowing a supercomputer to exceed 1015 operations per second. The Panasas parallel file system was instrumental in accomplishing this major milestone, achieving extreme performance for big data sets. Los Alamos National Laboratory (LANL) built that first petascale system, “Roadrunner,” using the Panasas parallel file system to maximize I/O performance for the most demanding simulations and modeling applications. Roadrunner still remains one of the Top 10 supercomputing systems in...

Categories: pNFS

Any of us who have been around the storage industry for a long time knows that standards adoption happens at what sometimes feels like a snail’s pace.  It takes the vision and dedication of people like Garth Gibson, Panasas founder and CTO, to bring momentous change to the industry by pushing the boundaries of technology.

Panasas was instrumental in driving the initial proposal for pNFS and Garth Gibson has been a key contributor to the creation of the open standard for high performance computing.   Take a listen to Garth Gibson talking at SC10 on the genesis of pNFS...

Traditional RAID is designed to protect whole disks with block-levelredundancy.  An array of disks is treated as a RAID group, or protection domain, that can tolerate one or more failures and still recover a failed disk by the redundancy encoded on other drives.  The RAID recovery requires reading all the surviving blocks on the other disks in the RAID group to recompute blocks lost on the failed disk.  As disks have increased capacity by 40% to 100% per year, their bandwidth has not increased substantially. 

Comparing models of drives from various vintages of...
