Another way to resolve this, for users with primary group assignments in the passwd file, is to use the “Map to Primary Group” policy.

Can’t copy greater than 4G file from Windows to StorEdge.

This problem may be seen on Windows 2000 and prior versions. If running Windows 2000, it can be fixed applying the latest service pack. If running an older version, there is no fix available, though you may be able to work around the problem with the Windows backup utility or a similar third party solution.

Can’t map drives via CIFS/SMB.

In order to map a drive or connect to a share, you must have read access to the directory to which the share points. If StorEdge is in domain mode, you must also be logged in to the domain. File and directory security can be checked at the StorEdge CLI.

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 “cacls <path>”. The path must include the volume name. If the path includes spaces, enclose the argument in double quotes, as in cacls “/vol1/my directory/my file”.

Cacls output contains the following information:

First, the basic mode information and UID/GID of the owner is displayed. Here is an example:

drwxrw----

34

22

/vol1/data

In this case, we can see that the item is a directory, with 750 permissions: Read/write/execute (7) for the owner (UID 34), Read/write for members of the owner’s group (GID 22), and no permissions (0) for everyone else.

Listed next are Creation time, FS Creation time, and FS mtime. These are timestamps associated with the file and the filesystem, generally only useful for troubleshooting timestamp issues.

Next is the Windows security descriptor. In its simplest form, it will read “No security descriptor”. This means that no Windows security is present, and that Windows will simulate security based on the above NFS permissions.

If a Windows security descriptor is present, the following information is displayed:

■Security Descriptor:The type of security descriptor. This can be disregarded.

■Owner:The user name or SID of the owner.

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.
