systems fails or is lost, the data is preserved at the central, corporate site, providing a fallback position for the remote locations and expediting the recovery of the remote site.

Sun StorEdge 5310 NAS supports Many-to-One Mirroring.

4.1.4.2One-to-Many Mirroring

One-to-Many Mirroring refers to the ability for a Master system to mirror simultaneously to multiple Mirror locations. It may seem a simple variation on the mirroring theme, but it actually introduces a number of complexities to mirroring.

AOne-to-Many mirror must be able to cope with different QOS levels on the different connections to remote systems. For example, if a system in Los Angeles is mirroring Many-to-One to systems in San Francisco and Houston and the link between Los Angeles and Houston becomes compromised (increased latencies, packet loss etc.), then the system must decide whether and when to - in the case of Real-time Mirroring - sever the link with the Houston system to preserve the QOS of local users. If the Los Angeles system in the prior example employs Pseudo Real- time Mirroring, then the system must decide how to manage situations where the mirror buffer is overrun for the San Francisco system, but remains intact for the Houston system.

Note that QOS policies must typically be decided on and managed by the user, placing not insignificant burden on them.

One-to-Many Mirroring is frequently confused with Replication and Push

Technology.

Sun StorEdge 5310 NAS does not support One-to-Many mirroring.

4.1.4.3Piggyback or Cascading Mirroring

Piggyback or Cascading Mirroring refers to a more common implementation of One- to-Many Mirroring, whereby a Master system mirrors to a Mirror, which in turn mirrors to another Mirror system (Los Angeles mirrors to Houston, and Houston mirrors to San Francisco).

Sun StorEdge 5310 NAS does not currently support Piggyback or Cascading mirroring.

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.
