Multiple subnets connected to StorEdge: Care must be taken when StorEdge is connected to multiple subnets, particularly when the subnets are disjoint, i.e. not connected to one another. A common example of this is a direct connection to a backup or database server.

The problem created by the disjoint subnets is that StorEdge registers each of its IP addresses via NetBIOS broadcast and/or WINS. The Domain Controller may select one of the addresses on a disjoint subnet, and fail to communicate with StorEdge, resulting in a failure to join the domain. The solution to this is to prevent NetBIOS registration of those addresses not connected to the main network.

In the case of the backup or database server, the solution is easy. The StorEdge “independent” NIC role was created expressly for this purpose. To configure the NIC role, proceed as follows:

1.Access the StorEdge via Telnet.

2.Press enter at the [menu] prompt and enter the administrator password.

3.Select option “A”, Host Name & Network.

4.Select option “1”, Edit fields.

5.Navigate through the fields with [Tab] or [Enter] until the “Role” field of the desired NIC is highlighted.

6.Select option “3”, Independent.

7.Select option “7”, Save Changes.

It is also possible to disable the NetBIOS registration without changing the NIC role. This can be done if you have a problem after attempting the above, or if you have a requirement to leave the role as primary. To make this configuration change, proceed as follows:

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

2.At the CLI, enter “load smbtools”, and then “smbwins exclude addr= 192.168.243.1”.

This action prevents these IP addresses from being registered via NetBIOS. However, the master browsers and WINS servers do not immediately remove these addresses. To accomplish this, proceed as follows:

3.Remove the entry for StorEdge from any WINS server databases.

4.Locate the master browser for the local subnet and any local Domain Controllers.

5.Enter “nbtstat –R” at the Windows CLI on each of these systems.

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.
