Thanks, Ted. You have seconds, and the Storage Community Group confirmed
sponsorship. I'll contact you offline to get you set up.

Project Overview:
I propose the creation of a project on opensolaris.org, to bring to the
community Solaris host-based data services; namely the Storage Archive
Manager or SAM and the Solaris shared file system QFS. These data services
exist today and are distributed commercially by Sun as the Sun StorageTek
Storage Archive Manager and Sun StorageTek QFS shared file system. The
software is delivered unbundled commercially for Solaris 9 and 10, but also
is compiled for and runs on Open Solaris.
Project Description:
Although SAM/QFS are positioned and marketed as two separate data services,
they are really a single code base. SAM is the Storage Archive Manager
component and consists of a policy based HSM. QFS is a shared or cluster file
system for Solaris, and supports shared QFS Linux clients.
The QFS shared file system is a high-performance, 64-bit Solaris file system.
This file system ensures that data is available at device-rated speeds when
requested by one or more users. The QFS shared file system supports from 1 to
128 compute nodes to allow file sharing to scale with computational needs.
QFS is ideally suited for Oracle RAC users and applications with a streaming
I/O profile
SAM is tightly integrated with QFS, and adds the features of a storage
archive manager to QFS. A SAM-QFS file system configuration allows data to be
archived to and retrieved from local or remote automated tape libraries or
disk at device-rated speeds. SAM manages QFS data online, nearline, and
offline automatically and in a manner that is transparent to the user or
application. Users read and write files to a SAM-QFS file system as though
all files were on primary storage. In addition, SAM protects QFS file system
data continually, automatically, and unobtrusively. Multiple file copies can
be made to many media types and storage tiers in a standard OPEN format. This
minimizes the requirement for traditional back-up only and provides fast
disaster recovery in an effective long-term data storage solution. A SAM-QFS
file system configuration is especially suited to data-intensive applications
that require a scalable and flexible storage solution, superior data
protection, and fast disaster recovery. This solution also includes an
integrated non-mirroring volume manager for performance, automated and
flexible policy management, and browser-based management tools.
Community Involvement:
By open sourcing SAM and QFS software, we will enhance OpenSolaris as a
storage platform. Those that adopt OpenSolaris will benefit from an open
storage platform, while providing valuable feedback to the commercially
distributed software sold and supported by Sun. We plan to develop our next
release of SAM/QFS in the Open Source community, so we invite community
feedback on our work in progress. We intend to make periodic (every few
weeks) code drops to the project page for download by the community. The
longer term strategy will be to migrate from CVS to Mercurial as a source
control tool and make the repository part of the open source project. This
will allow the community to comment on features and our code base as we work
through the development phase of the next and future commercial releases of
this software.Additionally, it will allow for community contributions.
