Abstract: Example embodiments of the present invention relate to a method, a system, and a computer program product for maintaining dynamically loadable namespaces. The method includes presenting, to an application, a file system having a global single namespace (SN) comprising a plurality of dynamically-loadable namespaces (DLNs) maintained in a capacity tier (CT) of object storage of a storage system. In response to a job submitted by the application, dynamically loading a first dynamically-loadable namespace, including the metadata only for the first dynamically-loadable namespace, associated with the job from the capacity tier of object storage into a fast tier (FT) of storage of the storage system.

Abstract: A computer-executable method, computer program product, and system for managing I/Os from a legacy compliant Application on a host, wherein the host is in communication with a data storage system including a burst buffer node, the computer-executable method comprising receiving a POSIX compliant message from the Application, wherein the message is associated with data on the data storage system and processing the POSIX message on the data storage system.

Abstract: A System, Computer program product, and computer-executable method of dynamically modifying data storage resilience within a two tiered data storage system, where the two tiered data storage system includes one or more fast data storage appliances and storage capacity tier wherein the fast data storage appliance is enabled to provide reliable data storage, the System, Computer program product, and computer-executable method including receiving configuration information from a node utilizing the two-tiered data storage system, wherein the configuration information provides characteristics of a job, analyzing the configuration information, updating use of the fast data storage appliances based on the analysis.
