When AVT is enabled and used in conjunction with a host multi-path driver, it helps ensure an I/O data path is available for the storage array volumes. The AVT feature changes the ownership of the volume receiving the I/O to the alternate controller.

After the I/O data path problem is corrected, the preferred controller will automatically reestablish ownership of the volume as soon as the multi-path driver detects the path is normal again.

Multi-Path Driver with AVT Disabled

When AVT is disabled, the I/O data path will still be protected as long as a multi- path driver is installed on each host connected to the storage array. However, when an I/O request is sent to a specific volume, and a problem occurs along the data path to its preferred controller, all volumes on that controller will be transferred to an alternate controller instead of just the specific volume.

3.3.6.9Password Protection

Note – IMPORTANT Executing destructive commands on a storage array can cause serious damage, including data loss. Without password protection, all options are available within this storage management software.

Note – IMPORTANT If you forget the password, contact technical support.

The storage management software provides a number of security features to protect data, including generation numbering to prevent replay attacks. Hashing and encryption are employed to guard against client spoofing and snooping.

For added security, you can configure a password for each storage array you manage. Because the password is stored on the storage array, each storage array that you want to be password protected will need a password. A specified password protects any options that the controller firmware deems destructive. These options include any functions that change the state of the storage array such as creation of volumes, modification of cache settings, and so on.

After the password has been set on the storage array, you will be prompted for that password the first time you attempt a destructive operation in the Array Management Window. You will be asked for the password only once during a single management session.

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.
