Sun has said that it plans to give some of its storage software and hardware technology to the open source community. The donated technology includes Sun -only administration features of Solaris ZFS which will be given over to the OpenSolaris open source community.
This will enable community members to combine OpenSolaris with hardware from any source to create compelling storage solutions at a fraction of the price of traditional proprietary storage vendors. This combination of open source and commodity hardware heralds a new stage in the storage industry.
Sun is taking the lead in creating a community-driven software development platform that speeds time-to-market for storage application development and which better addresses customers' ever-evolving data management and archiving needs.
"Just as free and open source code has changed the way server and desktop operating systems are developed, evaluated and deployed, today marks a big step in repeating this model for storage software technology," said Rich Green, executive vice president, Software, Sun Microsystems. "Sun is taking the lead in changing the market by enabling the creation of compelling low-cost storage solutions via the free and open availability of open source software, including Solaris, on commodity hardware from a wide-range of vendors including HP, Dell, IBM, and Sun."
Sun also announced the previously Sun-only flexible administration features of Solaris ZFS will be donated to OpenSolaris. ZFS is a dynamic file system, which simplifies management and adds functionality. The features donated include:
ZFS Clone Promotion feature, which allows storage users to turn a clone back into the active file system; Recursive Snapshots feature, which automatically creates snapshots for all descendent file systems.
Double Parity RAIDZ, a data protection enhancement to that provides storage users with enough protection so that no data will be lost if up to two devices fail Hot Spares for ZFS Storage Pool Devices, data protection disks that can replace failed or faulted devices, eliminating downtime after disk failure.
Sun and its partners are also introducing the following storage technologies into the OpenSolaris Storage community:
- Point-in-Time Copy data service and Remote Mirror data service
- NFS v4.1 (also known as parallel NFS)
- YANFS (formerly known as WebNFS)
- OSD device drivers and related software
- QLogic Fibre Channel HBA driver
