The host-based SM devices utility (if available for your operating system) is used to associate the physical device name and the volume name. Refer to “SANshare Storage Partitioning” on page 3-72for more information on assigning volume-to- LUN mappings.

3.3.6.14SANshare Storage Partitioning

This is a premium feature of the storage management software and must be enabled either by you or your storage vendor. The SANshare Storage Partitioning feature enables hosts with different operating systems (heterogeneous hosts) to share access to a storage array.

A storage partition is a logical entity consisting of one or more storage array volumes that can be shared among hosts. To create a storage partition after the total storage capacity has been configured into volumes, you must define a single host or collection of hosts (or host group) that will access the storage array. Then you will need to define a volume-to-LUN mapping, which will allow you to specify the host group or host that will have access to a particular volume in your storage array.

Storage partitions can be created quickly with the SANshare Storage Partitioning Wizard. The Wizard contains the major steps required to specify which hosts, volumes, and associated logical unit numbers (LUNs) will be included in the partition.

Based on the premium feature key purchased, a maximum of 64 storage partitions can be supported by the storage management software.

Note – IMPORTANT Windows NT, Solaris with RDAC, NetWare 5.1, and HP-UX 11.0 are restricted to 32 volumes per partition for this release.

A maximum of 256 volumes per partition can be defined; this is limited to the total number of volumes on your storage array. The software can further support up to two host ports in each host and up to eight ports in each host group, allowing a four- way cluster of dual-adapter hosts.

SANshare Storage Partitioning Example

In the example shown in Figure 3-30 on page 3-73,four hosts (Omaha A and B, and KC-A and B) are connected to Storage Array Midwest. Three storage partitions have been created, allowing these hosts to share access to the volumes on the storage array.

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.
