Windows created files are root owned when viewed via NFS. (In Workgroup mode)

Workgroup mode assigns ownership per share, based on the UID and GID settings configured when the share was defined. By default, this is set to UID and GID 0, leaving the files root owned. The best way to manage ownership of files in Workgroup mode is to have each user access StorEdge via a unique share, and define the UID/GID settings accordingly.

International NFS filenames are garbled or cannot be read from Windows. (Or vice versa.)

Windows uses Unicode UTF-8 for directory and filename storage. In order to read extended characters cross-platform, you must also use a UTF-8 codepage on the NFS clients.

By default, StorEdge assumes that all filename and directory name data received from NFS clients is ASCII text. If your NFS clients are using UTF-8 encoding, StorEdge needs to be configured to accept UTF-8 data. Note that this setting is only important if you intend to share data with Windows clients.

It is imperative that this configuration setting is made before any filenames with extended characters are written from NFS clients. Otherwise, filenames written prior to the change may become completely inaccessible. If a change is necessary on a system that already contains this type of data, any such data should be moved from the StorEdge, and re-migrated after configuring the system correctly. Please note that tape backup is not acceptable for this purpose. The data must be moved to a system that is using the same codepage as the NFS client that wrote the data.

The NFS UTF-8 setting is only available at the StorEdge CLI (command line interface).

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

2.At the CLI, enter “set nfs.utf8 yes”. This tells the StorEdge that the NFS clients send data in UTF-8 format. After setting any variables on the StorEdge, i.e. anytime the “set” command is used, the command "savevars" must be entered at the command line in order for the settings to persist though future server reboots.

In addition, you must configure the language codepage that StorEdge should use. The best way to do this is with the StorEdge Web Admin.

1.To use the Web Admin, connect with a Web browser to http://<hostname or IP address of your StorEdge>.

2.Click “Grant” or “Yes” to accept any Java software authorization windows and you will reach the login screen.

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.
