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.
