Sun Adds SSD Support to OpenSolaris Upgrade

Sun Microsystems released an upgraded version of its open source OpenSolaris operating system on Monday and included a number of storage-related enhancements to its ZFS file system. Perhaps most notable are management capabilities that let users better manage and take advantage of solid-state disks, which are showing up in more enterprise storage systems.

"We are adding the final piece to make it flash ready," said Matthew Baier, group manager for data center software marketing for Sun. "Flash provides the missing link between Dram and disks and we've enhanced the software to it automatically ties flash into a hybrid storage pool and can automatically use it in the best fashion."

ZFS will be able to monitor what an application is doing and optimize the use of the flash storage for high throughput or random reads and writes to boost performance. It can set some of the flash storage as read or write accelerators that will be managed by the file system, reducing the need for large caches of memory. The capabilities to recognize data usage patterns and optimize data placement for better performance comes from Sun's enterprise storage systems known as Amber Road.

The support for SSDs and other storage enhancements are part of a larger reworking on the software that includes a new version of the networking stack that includes better support for virtualization and multi-core, multi-threaded processors connected via virtual network interfaces. Called Project Crossbow, it is meant to make it easier to manage complicated deployment of multi-tier applications.

Additional storage enhancement include native support for Microsoft's CIFS as a peer to NFS and provides features and support for Windows semantics for security, naming and access rights, allowing transparent use and sharing of files across Windows, Linux and Solaris environments.
