What does the umask setting do?

The umask setting, allows the permissions of new files and directories to be specified on a per-share basis, which is consistent with the per-share UID and GID specification.

A umask is a file creation mask. It defines the permission bits to turn off when creating a file. Bits that are set in the umask are cleared in the mode of a newly created file. The umask is defined in octal because octal numbers comprise three bits, which maps easily to the UNIX file permission representation, for example; the UNIX permissions rwxr-xr-- can be represented as 754.

The umask is applied on a per share basis using standard UNIX rules, with the exception of the DOS read-only attribute. If the DOS read-only attribute is set in the file creation request, all write bits will be removed from the permission mode after the umask has been applied.

How do I set up user and group credential mapping? How do I share files between NFS and SMB users?

In Windows Domain Security Mode, this is accomplished via user and group mapping. Every time a Windows user accesses the StorEdge for the first time, a new user mapping is created. Similarly, a new group mapping is created the first time each user from a particular Windows primary group logs in.

These mappings permanently associate the Windows user’s ID with a particular NFS UID. This allows users with both NFS and SMB accounts to access their own data from either type of client, and to share data with heterogeneous workgroups. The mapping rules determine how the NFS UID or GID for a particular Windows user or group is obtained.

It is strongly recommended that you define a mapping rule and import NFS accounts to StorEdge prior to the migration of data. This will minimize the amount of manual configuration required.

The primary tool to accomplish this is the selection of user and group mapping rules. This can be accomplished via the Web Admin, or via the CLI. Each method is detailed below.

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.

3.Type the administrator password to access the administration interface.

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.
