Scale-out NAS vendors like to brag about what they’ve done inside their storage architecture to distribute data evenly and allow the performance of their systems to scale as additional storage nodes are added. And at Panasas, we’re no exception.

However, while linear performance scaling inside a storage architecture is indeed critically important, that is only one half of the picture. With many scale-out NAS systems, system administrators frequently run into a serious challenge – how to evenly balance their compute clients across the storage system.

The root cause of this...

Panasas has a long history with object storage, starting with Dr. Garth Gibson’s groundbreaking work in the early 1990’s at Carnegie Mellon.  Garth’s work on NASD (Network Attached Secure Disk) became the foundation for the OSD (Object Storage Device) standard and Panasas file system.  He is also credited with being the key inspiration for the Google File System (GFS).  Both file systems are object based storage, but should not be confused with web object storage systems such as Amazon Web Services or Microsoft Windows Azure.  In fact there are two classes of object...

Panasas founder and chief scientist, Dr. Garth Gibson, and Steve Conway, research vice president in IDC's high performance computing group took some time recently to discuss HPC trends and forces affecting storage in the HPC market. The role that big data plays in HPC storage, now and in future scenarios is discussed in this third and final video in this series. Garth and Steve explored Parallel NFS (pNFS) in the first installment; they covered solid state drive (...

Object storage is a generic term that describes an abstract data container and related metadata. The data can be an image, a file, a sensor reading, or whatever an application needs to store. The metadata describes the data, including a useful name for that data, where it came from, when it was created, how long it is valid, and whatever else may be important to the application that creates and uses the data object.

Objects are explicitly created and deleted, which is unlike storage on a block device. In a traditional block storage system, a file system or...

Calvary Chapel chose Panasas® ActiveStor® 14 to streamline its tapeless digital workflow and accelerate content distribution in order to distribute its teachings to a nationwide congregation.

Previously, with out-of-date infrastructure, Calvary’s video production team suffered performance delays, capacity limitations and file sharing inefficiencies that impacted the organization’s ability to keep up with modern media workloads. Panasas, with reseller partner ReelData, designed a tapeless, digital workflow using Panasas...

Panasas Director of Channel Sales for EMEA, Derek Burke, points out that pure performance isn’t the only important aspect of an HPC storage solution, especially when it’s tasked with processing multiple technical computing application workloads. Here is what he says… 

 

Whether Panasas® ActiveStor® is the storage backbone of a departmental HPC system for a specific application domain or for a centralized HPC service for a diverse range of users and applications – ‘performance’ is generally given the highest consideration.

From a compute performance...

Happy birthday, RAID!  Twenty-five years ago, in March 1988, Panasas founder and chief scientist, Dr. Garth Gibson, published the paper “A Case for Redundant Arrays of Inexpensive Disks (RAID)” with co-authors David Patterson and Randy Katz, inventing a concept that would prove central to the storage industry for decades to come. Congratulations to all three of these storage visionaries!

For those of you who have not yet viewed them, Garth recorded a series of ...

In late February, Red Hat announced the release of Enterprise Linux 6.4 with pNFS support. This validates the pNFS standard that Panasas and its founder and chief scientist, Dr. Garth Gibson, have long been championing. While the announcement did not receive much fanfare in the press, Red Hat adoption of pNFS is a key advance for the pNFS standard which until now has lacked a mainstream commercial release vehicle. We believe this to be the most important step forward for pNFS since the protocol was first included in the upstream 3.0 Linux kernel in 2011, after years of effort by engineers...

Quality is obviously important for any software product and storage systems have particularly demanding quality requirements.  Customers expect to reliably retrieve the data they store.  Unfortunately, software has bugs, and the consequence of a bug in a storage system ranges from minor inconvenience, to system down time, to corrupted or lost user data.  The recently published paper, "A Study of Linux File System Evolution," by Lu et. al., presented at the FAST'13 Conference, describes...

Panasas founder and chief scientist, Dr. Garth Gibson, and Steve Conway, research vice president in IDC's high performance computing group took some time recently to discuss HPC trends and forces affecting storage in the HPC market. The role that solid state technology plays in HPC storage, now and in future scenarios is discussed in this second of three video chapters. pNFS was covered in the first installment and big data will be explored in the third and final chapter (coming soon).
