Fastest Parallel File System at Any Price Point Built for Price/Performance, Engineered for Manageability 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 PanFS BeeGFS Lustre GPFS Panasas v. Competition GB/s/100 HDD PanFS on ActiveStor Ultra 1PB, 16GB/s, $150K Limited Time Special Offer Comparative Read Performance of PanFS v. Competitive Parallel File Systems in GB/s This means that Lustre, GPFS and BeeGFS need nearly 2X more drives (at 2X the cost) to achieve the same performance as Panasas.

Purchase Criteria and Operational Challenges Disconnect Hyperion Survey Reveals Organizations’ Misalignment in HPC Storage Buying Decisions Downtime: Almost half of the surveyed sites experience storage system failures once a month or more frequently. Downtimes range from less than one day to more than a week. A single day of downtime costs from under $100,000 to more than $1 million.
