April 17, 2007 - Today, Sun Microsystems added a new family of Sun StorageTek 2500 arrays to the modular disk array family, joining the Sun StorageTek 6140 array and the Sun StorageTek 6540 array.

Storage Meets OpenSolaris (4:36)

Find out how Sun's contribution of storage technologies to the OpenSolaris community will help speed storage application development.

The standards-based, plug-and-play Sun StorageTek 2500 arrays are an excellent fit in government and telco environments, delivering several key advantages:

  • 25 percent better price/performance than its competitors
  • One-third greater rack density than most competitors
  • Low total cost of ownership
  • Excellent manageability and serviceability

The new arrays include the Common Array Manager (CAM) software free of charge. With the CAM software, it's easy to configure and manage the arrays, saving time and money. The CAM software spans the entire modular disk array portfolio, allowing customers to scale up or down using the same management interface.

Free and Open Storage Software

This release comes on the heels of another key storage announcement. Last week, Sun extended its position as the top contributor of code to the free and open source software community[1] by donating storage software code to the OpenSolaris Project. This enables 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.

"Thanks to ZFS and other features, Solaris is the best operating system for storage solutions," says Nigel Dessau, Sun senior vice president, Storage Marketing and Business Operations. "By contributing storage-related code to the OpenSolaris community, Sun makes it easier than ever for customers to develop storage solutions that meet their needs."

Open Source Stack

Sun is the only company that offers an open-source stack--from the processor to the operating system to the application layer. (Learn more about the dozens of open source projects in which Sun participates.)

By open sourcing its software stack, Sun gives control to developers and customers, who can mix and match alternative operating systems, middleware, and applications on industry-standard hardware. Sun's approach keeps customers from being locked into proprietary systems. There's no risk or long-term commitment required when using open source software, and customers can participate at the level that suits them best.

"Sun helps customers ‘shrink the stack' if they so choose," says Bob Porras, Sun vice president, Solaris Storage Software. "Some companies want to develop products around core open technologies; others want to put the entire open stack to use. Sun's approach makes both strategies viable."

Best for Storage

The Solaris OS includes numerous features that make it the best choice for storage-related solutions. By open sourcing this code, Sun delivers several advantages. Developers can now create secure, scalable, and reliable applications faster and more easily.

Key open source storage-related software includes:

  • Solaris ZFS
    The world's most advanced file system delivers data integrity, tremendous performance, and integration of file-system and volume-management capabilities.

  • NFS
    OpenSolaris contains both client and server implementations of the IETF NFS protocols from version 2 through version 4. New OpenSolaris projects are also underway for NFS v4.1 (also known as parallel NFS) which provides scalable parallel access to files distributed among multiple servers.

  • YANFS
    Formerly known as WebNFS, YANFS is a simple, platform- and OS-independent file access protocol that offers reliable, high-performance file access and distribution.

  • Point-in-Time Copy and Remote Mirror data services
    These services--the first commercial replication software to be open-sourced--create and manage data snapshots, and provide data mirroring for disaster recovery and migration.

  • iSCSI
    OpenSolaris contains both the initiator and target support for the IETF iSCSI protocol which allows the use of the SCSI protocol over TCP/IP networks.

  • OSD
    OpenSolaris SCSA-compliant device drivers and related software provide both initiator and target support for storage devices that adhere to the SCSI Object-Based Storage Device (OSD) command protocol.

  • Fibre Channel support
    OpenSolaris is arguably one of the best SAN-enabled operating systems with a full Fibre Channel stack including Fibre Channel Transport, interfaces for Fibre Channel HBA Drivers and hardware, Storage Management APIs, and Storage Management Utilities.
Sun also plans to open source additional storage code over the next several months, including:
  • Common Internet File System (CIFS) server

  • Sun StorageTek 5800 storage system (Honeycomb) client interfaces along with the Honeycomb software developer kit (SDK) and Honeycomb emulator/server.

  • SAM-FS (Storage Archive Manager) provides data classification, policy based data placement, protection, migration, long-term retention, and recovery capabilities for organizations to effectively manage and utilize data according to their business requirements. SAM-FS is used exensively in security/surveillance, digital video archiving, and medical imaging data environments.

  • QFS Sun's shared file system software delivers significant scalability, data management, and throughput for the most data-intensive applications. Well known today in the traditional high performance computing (HPC) arena, QFS is increasingly being used in commercial environments that require multiple host, high speed access to large data repositories.

In addition, today QLogic is contributing their Fibre Channel HBA driver code to the OpenSolaris storage community. For the first time, developers have access to an I/O stack from the application through to the operating system.

Community Counts

Since its launch nearly two years ago, OpenSolaris.org has grown into one of the most exciting and thriving communities in the open source world. As of the end of March, there were:

  • 40,890 registered community members
  • 100,000 postings to OpenSolaris discussion groups
  • 42 registered OpenSolaris user groups
  • 937 bugs reported by the community
  • 478 fixed/closed/in-progress bugs reported by the community
  • 151 community code contributions integrated into OpenSolaris (putbacks)

Now the OpenSolaris ecosystem grows even larger with the launch of a community portal around the open source storage software stack. Developers can use the portal to download code, dive into particular open source storage projects, review design documents, and leverage developer expertise via discussions, including email forums.

"The new portal builds a strong, vibrant community around open storage," says Porras. "It enables storage application developers to put open storage to work today, as well as evolve the overall Solaris platform moving forward."

Participate Today

If you're not already part of the OpenSolaris community, get started today by downloading the source code or checking out the open storage portal.

[1] Sun is the largest contributor to free software. In the Linux space alone, Sun has donated 3x the amount of code as IBM and more than 5x the amount as Red Hat. This does not even include OpenSolaris, OpenJDK, GlassFish, OpenSPARC, NetBeans, and other contributions.
