Proc filesystem

The /proc filesystem is a virtual filesystem used to collect system data. The location of some of the more useful data is listed below. To collect the data, copy the file, or use the “cat” CLI command to dump it to the screen while logging the terminal session.

/proc/cifs/DOMAIN.USER.6789ABCD…

These are user access tokens. They may be useful in troubleshooting SMB issues.

These file names begin with the domain name, then the username, then some hexadecimal digits. The hexadecimal digits are a representation of the IP address, which can be used to discern between multiple logins for a user. If you do not see the user token that you need, it may be necessary to log the user off for thirty seconds, and then back on in order to capture the token.

/proc/cifs/pdc

The currently connected domain, domain controller, and the IP address of the domain controller.

/proc/cifs/ntdomain

A list of all trusted domains, their related SIDs, and the local machine and local domain SIDs.

Network trace

A network trace can be very valuable towards diagnosing problems that involve network communication. Set the trace to filter traffic between StorEdge, the client, and any authentication server. In this case, it is usually best to use the StorEdge built-in packet capture utility.

1.6.2.8StorEdge network capture utility

StorEdge includes a built-in network monitoring tool. This allows you to capture packets from the network and save them to a file. This can be a valuable troubleshooting tool.

To configure network monitoring, it must first be loaded at the StorEdge CLI.

1.To access the StorEdge CLI, connect to the StorEdge via Telnet or serial console, and type “admin” at the [menu] prompt and enter the administrator password.

2.At the CLI, enter “load netm”. Then type “menu” to configure capture and capture packets.

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.
