Once the user has navigated to the .chkpnt directory at any point in the directory hierarchy, there are no .chkpnt subdirectories, i.e., there are no nested .chkpnt directories. Users can then access checkpointed versions of the entire volume by navigating to the .chkpnt directory at the root of the volume.

Compatibility Issues

In order to avoid name conflicts between user applications and existing files, each

.chkpnt entry possesses a number of special characteristics. As previously noted, it will not show up in directory listings. Applications not aware of the .chkpnt directories will not be able to "see" the directories - thereby preventing potential problems with applications that traverse directory hierarchies like backup and virus scanning programs.

Second, if users already have existing files or directories named .chkpnt, these objects will retain their existing meaning. Users with these pre-existing objects have one of two options:

a. they can rename the existing objects

or

b. the StorEdge OS provides a mechanism as part of the chkpnt command structure to enable users so affected to change the access name for the virtual checkpoint directories.

The syntax for the command is:

chkpnt vname {volname}

shows the current hidden directory name for {volname} chkpnt vname {volname} [new-name]

sets the hidden directory name to new-name

Once the virtual checkpoint directory name is set with the chkpnt vname command, StorEdge will disallow the creation of objects with the same name as that specified by the user for the virtual checkpoint directories.

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.
