the checkpoints. A large amount of space and system memory is required for checkpoints. The more checkpoints there are on a system, the more it will affect the system’s performance.

Checkpoints are generated from changed blocks. If system usage consists of large amount of file changes then the system will base the next checkpoint off of the changed blocks. It is recommended that when using checkpoints the volume should be allocated at no more than 70% this would allow for system operation to maintain maximum performance as well as give space to the system OS. At 90% disk space utilization, StorEdge will stop creating scheduled checkpoints. At 95% StorEdge will automatically delete checkpoints to free space for system operations.

Checkpoints can be created in two ways: automatic and manual. If the user selects the automatic checkpoints, checkpoints are created and removed based on the scheduling that user specifies for the checkpoints. This scheduling is enforced by a checkpoint manager thread. On the other hand, checkpoint manager does not control manually created checkpoints (though users can create manual checkpoints that will be removed automatically by using the same naming convention that system uses for automatic checkpoints).

How do I set up checkpoints?

To utilize this StorEdge feature, you must first go to the file volume operations menu and enable checkpoints. To do so, proceed as follows:

1.Access the StorEdge via Telnet or serial console.

2.Press [Enter] at the [menu] prompt and enter the administrator password.

3.Enter “D”, “Disks & Volumes” in the configuration section to set up checkpoints.

4.Enter the letter corresponding to the system disk that contains volume that requires checkpoints.

5.Select the number corresponding to the volume that requires checkpoints.

6.Select option “6”, “Checkpoints”.

7.Select option “1”, “Edit fields”.

8.Use [Tab] or [Enter] to navigate through fields.

9.Select option “Y”, “Yes” to enable checkpoints on the selected volume

10.Pseudo volume checkpoint name is forced to “Yes”

11.Select option “Y”, “Yes” to make the checkpoint volume visible.

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.
