02 Simple, Frustration-Free Management

Lustre management is CLI-based (command-line interface) with inconsistent open-source and commercial GUI (graphical user interface) versions for monitoring, so admins need additional training on DDN’s version of Lustre to manage it. Lustre admins must manually tune and re-tune their systems to maintain performance as workloads change. Recovery from a Lustre crash can be painstakingly difficult, often taking admins weeks – or even months – to fully resolve.

The PanFS parallel file system has built-in automation features that manage data placement, so PanFS admins don’t have to worry about tuning, retuning, or error recovery. It also includes an easy-to-use single management console, allowing you to perform all management tasks through either the CLI or the GUI. You get easy monitoring and performance management, flexible storage allocations, as well as addons, upgrades, and firmware updates in just a few clicks.

03 Scalable Data Protection and Reliability

Lustre has a primitive Data Protection Comparison data reliability architecture with slow rebuild rates that increase the odds of data loss, especially as the total capacity of the system grows. Crashes are common, and rebuilds at scale can take many days. Lustre’s old-school hardware-based RAID implementations do not provide file level erasure coding.

The PanFS parallel file system uses a modern data reliability architecture that gets even more reliable as the total capacity of the PanFS realm scales, with rebuilds taking hours rather than days. Patented PanFS per-file object erasure coding ensures per-file fault isolation, safeguard against total loss of multiple storage nodes, and the ability to use different RAID schemes for different files within the same volume. The PanFS reliability architecture enables continuous data integrity checks by verifying the erasure codes for each file.

04 No Tiers Means No Tears

Lustre is typically deployed in a multi-tier system where you pay for hardware that doesn’t contribute to your performance. Because high performance comes from the uppermost scratch space in a Lustre environment, the hardware you buy for other tiers, such as project storage, is just for capacity – it doesn’t contribute to the visible performance of your storage system. And Lustre’s unreliability requires duplicating the data you’re working on and copying it back and forth between project storage and scratch space.

The PanFS parallel file system utilizes a highly reliable, single-tier architecture that allows you to read and write project storage directly. Equally performant read and write streaming is ideal for storage consolidation projects and multipurpose usage. With Panasas, you can simultaneously host unified scratch, home directories, and project file storage on a single platform that delivers HPC streaming and mixed workload performance.

05 Unparalleled Uptime

Lustre’s emphasis on high performance comes at the cost of reliability, which means lower uptime. Block-level RAID like Lustre is prone to silent corruption, system failures, and long unplanned downtimes. Storage that is frequently down prevents the compute cluster from executing anything, which ultimately wastes a very expensive resource.

Panasas has hardened the PanFS parallel file system over two decades to deliver the most reliable and stable HPC storage platform. PanFS has built-in prevention and automated rapid failure recovery logic that avoids Lustre’s common corruption issues to deliver unmatchable uptime. With Panasas, you get continuous background data scrubbing, capacity balancing, snapshots, and quad-replicated directories. One PanFS admin has reported going over 8 years without a single moment of unplanned downtime.

34% of organizations report monthly storage outages – nearly 20% are down for a week or more.
