NAS Agent Direct Data Transfer for VTL Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data archiving systems, particularly those using Virtual Tape Library (VTL) appliances, often become bottlenecks due to the need for all messages and information packets to pass through them, leading to inefficiencies in data archiving and restoration processes.
Innovation Solution
A network-attached storage (NAS) server with an agent is configured to intercept messages for data backup, allowing direct data transfer from the source to the destination without relying on the VTL appliance, thereby reducing the load on the VTL appliance and enhancing archiving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a VTL appliance is used to intercept and archive data, then data archiving functionality is provided, but the VTL appliance becomes a bottleneck for communications
Solution Approach 1:
The patent segments the data archiving process into two independent paths: control messages continue to pass through the VTL appliance for compatibility, while data transfer is separated and handled directly by the NAS server through the agent. This segmentation allows the VTL appliance to maintain its archiving functionality without becoming a bottleneck for all communications.
Solution Approach 2:
The agent installed on the NAS server acts as an intermediary that receives control messages from the VTL appliance and initiates direct data transfer between the source and destination without requiring all data packets to pass through the VTL appliance. This intermediary enables the NAS server to perform archiving functions independently.
2Reliability
If all messages and information packets pass through the VTL appliance, then centralized control is maintained, but performance and throughput are reduced
Solution Approach 1:
The patent segments communications into control messages and data transfer. Control messages continue to pass through the VTL appliance for centralized control, while data transfer is separated and handled directly by the NAS server. This segmentation maintains centralized control for coordination while enabling high-speed direct data transfer.
Solution Approach 2:
The agent on the NAS server serves as an intermediary that receives control instructions from the VTL appliance and executes direct data transfer operations. This intermediary enables the system to maintain centralized control through the VTL appliance while achieving high throughput through direct peer-to-peer data transfer.
3Adaptability or versatility
If data transfer goes through the VTL appliance, then compatibility with existing tape library software is maintained, but archiving efficiency is reduced
Solution Approach 1:
The patent segments the archiving process so that control messages pass through the VTL appliance to maintain compatibility with existing tape library software, while data transfer is separated and handled directly by the NAS server. This allows the system to maintain software compatibility without sacrificing archiving efficiency.
Solution Approach 2:
The agent on the NAS server acts as an intermediary that receives control messages from the VTL appliance and initiates direct data transfer. This intermediary enables the system to maintain compatibility with existing VTL software while achieving improved archiving efficiency through direct data transfer paths.
Data Source
AI summary
For backing up of data from a source to a destination, a virtual tape library (VTL) appliance intercepts a message for backing up the data. In response to the intercepted message, the VTL appliance sends a command to initiate the backing up of the data. A network attached storage (NAS) server, which is the source of the data and is coupled to the VTL appliance by a network, receives the command. An agent located in the NAS server is triggered in response to the command to directly transfer the data from the source to the destination. The agent informs the VTL appliance upon completion of the transfer of the data.
