MarFS: A Scalable Near-POSIX Name Space over Cloud Objects – New Features

Presented by

Kyle Lamb and David Bonnie, Storage Technical Leads, Los Alamos National Laboratory

About this talk

It has been said that Objects are for applications and POSIX is for people. The HPC community as well as many other large scale IT organizations have legacy applications and users that know, use, and depend on a near POSIX environment with real folders, ease of renaming and reshaping trees, and other powerful concepts in POSIX. MarFS is designed to provide a scalable near-POSIX name space over standard object systems, with target scaling out to trillions of POSIX files, hundreds of Gigabytes/sec of data bandwidth, and millions of POSIX metadata operations/sec. MarFS, now in use in production, has met the original developmental goals and many feature enhancements are now being developed. Features such as cloud storage flexibility enabled by a data abstraction layer, calculation of parity for incoming data, and expanded metadata scalability.

Cloud computing is a general concept that incorporates software-as-a-service (SaaS), platform-as-a-service (PaaS), infrastructure-as-a-service (IaaS) and other recent well-known technology trends in which the common theme is reliance on the Internet for satisfying the computing needs of the users. This channel features presentations by thought leaders who cover the key topic areas in this increasingly important field.
