CONCURRENT CODE UPGRADE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240296037 titled 'CONCURRENT CODE UPGRADE
The method described in the abstract involves upgrading the software version on a storage appliance while ensuring all hosts in the system have discovered paths to volumes before continuing the upgrade process on other nodes.
- Installing target software version on first node of storage appliance
- Restarting first node while current software version runs on other nodes
- Checking if all hosts have discovered paths to volumes on first node
- Allowing upgrade of other nodes if paths are discovered
- Preventing upgrade if paths are not discovered
Potential Applications: - Data storage systems - Software upgrades in network environments - System maintenance in large-scale storage setups
Problems Solved: - Ensuring seamless software upgrades without disrupting system functionality - Preventing potential data loss during upgrade processes - Streamlining upgrade procedures in complex storage systems
Benefits: - Minimized downtime during software upgrades - Enhanced system reliability and stability - Improved overall performance of storage appliances
Commercial Applications: Title: "Efficient Software Upgrade Method for Storage Appliances" This technology can be utilized in data centers, cloud storage providers, and enterprise storage solutions to streamline software upgrade processes, reduce downtime, and enhance system performance.
Prior Art: Research related to storage system software upgrades, network maintenance procedures, and data center management tools can provide insights into similar methods and technologies.
Frequently Updated Research: Stay informed about advancements in storage system management tools, network maintenance protocols, and software upgrade automation to enhance the efficiency of storage appliance upgrades.
Questions about the Efficient Software Upgrade Method for Storage Appliances:
1. How does this method improve the reliability of storage systems during software upgrades? This method ensures that all hosts have discovered paths to volumes before continuing the upgrade process, reducing the risk of data loss and system disruptions.
2. What are the key benefits of using this method in large-scale storage environments? By minimizing downtime, enhancing system stability, and improving overall performance, this method can significantly impact the efficiency of storage system operations.
Original Abstract Submitted
a method comprises: installing the target software version on a first node of the storage appliance; restarting the first node of the storage appliance while also running the current software version on other nodes of the storage system; subsequent to said installing the target software version and said restarting of the first node, determining if all hosts of the storage system have discovered paths to volumes on the first node; responsive to determining that all hosts of the storage system have discovered paths to volumes on the first node, permitting the ccu of the nodes to continue to upgrade one of the other nodes of the storage system from the current software version to the target software version; and responsive to determining that not all hosts of the storage system have discovered paths to volumes on the first node, preventing the ccu of the nodes from continuing.
