3.3.6.16Managing Persistent Reservations

Caution – The Persistent Reservations option should be used only under the guidance of a technical support representative.

The Persistent Reservations option enables you to view and clear volume reservations and associated registrations. Persistent reservations are configured and managed through the cluster server software, and prevent other hosts from accessing particular volumes. Unlike other types of reservations, a persistent reservation reserves access across multiple host ports, provides various levels of access control, offers the ability to query the storage array about registered ports and reservations, and optionally, provides for persistence of reservations in the event of a storage system power loss.

The storage management software provides functionality for managing persistent reservations in the Array Management Window (Figure 3-34). The Persistent Reservation option enables you to:

■View registration and reservation information for all volumes in the storage array

■Save detailed information on volume reservations and registrations

■Clear all registrations and reservations for a single volume or for all volumes in the storage array

For detailed procedures, refer to the Array Management Window online help.

Management of persistent reservations through the script engine and command line interface is also supported. For more information, refer to the Enterprise Management Window online help.

5310 NAS specifications

Sun Microsystems, known for its innovative computing solutions, launched the Sun 5310 Network Attached Storage (NAS) system, which marked a significant advancement in the realm of storage solutions in the early 2000s. The 5310 NAS was designed to provide high-performance, reliable, and scalable storage tailored for enterprise environments.

One of the standout features of the Sun 5310 NAS is its file-serving capabilities, which support multiple protocols, notably NFS (Network File System) and CIFS (Common Internet File System). This dual-protocol support allowed organizations to seamlessly integrate the NAS into diverse IT ecosystems, facilitating interoperability between UNIX, Linux, and Windows systems. The enhanced file-sharing capabilities made it an ideal solution for businesses with mixed operating environments.

The Sun 5310 NAS incorporates cutting-edge technologies to ensure high availability and data integrity. The system utilized a RAID (Redundant Array of Independent Disks) technology, providing various RAID levels to protect against data loss while optimizing performance. Additionally, the device featured hot-swappable drives, enabling maintenance and upgrades with minimal downtime, a crucial factor for business continuity.

Equipped with advanced management software, the Sun 5310 NAS offered users an intuitive interface for monitoring storage health and performance. This software included comprehensive reporting functionalities that allowed IT administrators to oversee usage patterns and capacity planning efficiently.

Scalability was another defining characteristic of the Sun 5310 NAS. The system could easily expand with additional storage modules, accommodating the growing needs of an organization without the necessity for complete system overhauls. This flexibility ensured that businesses could adapt their storage solutions to meet evolving data storage needs without incurring significant costs or disruptions.

In terms of performance, the Sun 5310 NAS featured high I/O throughput achieved through its robust hardware architecture and optimized file serving capabilities. This performance baseline was crucial for organizations that relied on heavy data workloads and required rapid access to information.

In summary, the Sun 5310 NAS from Sun Microsystems embodied a forward-thinking approach to network storage, blending reliability, scalability, and multi-protocol support. Its user-friendly management software, combined with the robustness of RAID technology and hot-swappable drives, made it a preferred choice for enterprises looking to streamline their storage infrastructure while safeguarding critical data.
