These are the result of an ICMP message from another router or firewall, typically due to mis-configuration of that device. It is also possible to configure StorEdge to ignore ICMP requests to change the default gateway.

■Check the “Use” statistic in the routing table. This statistic indicates how many times a route has been used. If you have defined a route for a specific purpose, such as mirroring, and this counter is not incrementing, then the route was most likely not defined correctly.

Also, check the basics. Try another client on the same subnet, try another cable, try another switch port for both client and StorEdge.

To escalate TCP/IP connectivity issues collect a network trace from the StorEdge, using the internal utility, and also from the client or server attempting to connect to the StorEdge if possible. Also include details on the client system, especially network configuration information and operating system version. A network diagram which includes IP addresses and information on switches and router hardware on the network is also very helpful.

1.6.2.10Performance Issues

The following is a general list of barriers to peak performance:

Network Configuration:

■Verify speed and duplex negotiation.

■Verify that port aggregation is configured when multiple NICs are connected to a subnet.

■Ensure that Jumbo frames are not configured.

■Ensure that Spanning Tree Protocol is not configured.

■Ensure that all configured NIS, DNS, SMTP servers and etc. are reachable and resolvable. (Note: always configure by IP rather than name where possible)

Configuration:

Checkpoints: Checkpoints can be overused and have a drastic effect of performance of the system. Verify that customers understand the use of checkpoints and how the retention policy can play a significant role in system performance.

If using ADS, improper configuration of dynamic DNS configuration can adversely affect performance.

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.
