Host Device Automated iSCSI Connectivity Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for establishing iSCSI connectivity between host devices and storage systems require complex manual processes, leading to inefficiencies, errors, and increased costs due to the need for manual configuration by administrators.
Innovation Solution
Implementing automated host provisioning using multi-path input-output (MPIO) drivers that obtain connectivity information from storage systems and automatically configure host bus adaptors to establish iSCSI connectivity, reducing the reliance on manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processes are used to establish iSCSI connectivity between host devices and storage systems, then administrators can configure connectivity, but the process becomes complex, time-consuming, and error-prone
Solution Approach 1:
The host device automatically discovers storage system ports and configures iSCSI connectivity parameters (IP addresses, MTU sizes, VLAN configurations) without requiring administrator intervention. The MPIO driver obtains connectivity information directly from the storage system and performs self-configuration, eliminating manual processes and reducing errors.
Solution Approach 2:
The system performs preliminary discovery of storage system ports and pre-configures connectivity information before the host device needs to establish connectivity. The storage system provides connectivity parameters in advance, allowing the host to quickly establish connections without manual configuration steps.
2Productivity
If manual configuration processes are executed for each host device, then connectivity can be established, but the process becomes costly and time-consuming
Solution Approach 1:
Each host device automatically discovers available storage system ports and configures its own iSCSI connectivity using information obtained from the storage system. This eliminates the need for administrators to manually configure each host, significantly reducing configuration time and increasing provisioning productivity.
Solution Approach 2:
The storage system pre-publishes connectivity information for its ports, allowing host devices to quickly obtain configuration parameters without waiting for manual administrator input. This preliminary preparation of connectivity data accelerates the host provisioning process.

AI summary
A host device comprises a processor coupled to a memory. The host device is configured to obtain from a storage system connectivity information characterizing one or more ports of the storage system, and to automatically establish connectivity of a particular type between the host device and one or more logical storage devices of the storage system based at least in part on the obtained connectivity information. For example, the host device can obtain the connectivity information directly from the storage system or via at least one intermediary device such as a management station. In some embodiments, the obtaining and automatically establishing are performed by at least one multi-path input-output driver of a multi-path layer of the host device. The connectivity of a particular type illustratively comprises Internet Small Computer System Interface (iSCSI) connectivity between the host device and the storage system, although other connectivity types can be supported.
