The announcement last week that Whamcloud (the start-up created to continue development of Lustre) has secured funds from OpenSFS to enhance Lustre’s features and functions, is a step in the right direction. The investment certainly demonstrates that Lustre is a supported environment; it shows clear direction and should give open source customers more confidence that Lustre’s development will continue slightly more strategically than it has in the past.
We can and do integrate the Lustre open-source file system to support our high-performance server and storage clusters. However, our deployment of Lustre is primarily as a result of a customer’s specific request for the product (as opposed to us proactively recommending it). Given than many of our customers do not have in-house HPC expertise, Lustre’s recent lack of support and ongoing product development has always held us back. We generally recommend customers use IBM’s General Parallel File System (GPFS).
In the short term, this will not change. We will probably continue to recommend GPFS to customers. However, with continued investment in Lustre’s support and development, perhaps we will see more deployments in the future (and in all customers, not just those with the in-house skills and resources to use it effectively).
