ACI_DRIVE_FUP

force drive allocation (also possible, if

 

 

the drive is occupied)

 

 

 

 

ACI_DRIVE_FDOWN

force delete drive allocation (also

ACI_DRIVE_DOWN

deleted reservation normal (only

The drive can only be put in the DOWN status by

ACI_DRIVE_FDOWN if the drive is occupied.

A drive may only be available to a single client at a time. The drive status is defined to be either UP (active) or DOWN (inactive) to requesting clients. When the client sets the status to ACI_UP, it is exclusively available to that client. If another client already has the drive status set to ACI_UP, the request is returned with the d_errno set to EUPELSE. If the client indicates a status of ACI_DOWN, the drive is unavailable to the client requesting drive access.

A drive must be empty to modify the drive access parameter to ACI_DOWN.

Server specifications

ADIC Server, short for Advanced Data Interoperability and Communication Server, is a modern server platform designed to facilitate seamless data exchanges, interoperability, and communication among various applications and systems. Tailored for organizations that require robust data management solutions, ADIC Server stands out due to its unique features and flexibility.

One of the main features of ADIC Server is its comprehensive data integration capabilities. It supports a wide array of data formats, including JSON, XML, and CSV, allowing organizations to connect diverse data sources effortlessly. This flexibility is critical in a data-driven world, ensuring that businesses can leverage their data regardless of where it resides.

ADIC Server also boasts a rich set of APIs, enabling developers to create custom applications and integrations without extensive overhead. This feature allows businesses to extend their existing systems and ensure that they can adapt their operations quickly to meet ever-changing market demands.

In terms of technology, ADIC Server is built on a microservices architecture, which ensures scalability and reliability. Each microservice can operate independently, allowing organizations to scale specific components of the system according to their needs. This modular approach also promotes resilience, as failure in one service does not directly impact the entire server functionality.

Security is another hallmark of ADIC Server. The platform incorporates advanced encryption protocols and authentication mechanisms to safeguard sensitive data transactions. Role-based access control (RBAC) ensures that data is only accessible to authorized personnel, thus significantly reducing the risk of data breaches.

Another characteristic deserving mention is the server's exceptional performance. ADIC Server is optimized for high throughput and low latency, making it suitable for real-time data processing. Organizations can rely on the server to handle large volumes of data from various sources without compromising speed or efficiency.

Moreover, its user-friendly interface and robust monitoring tools facilitate effective management and troubleshooting. Administrators can easily track performance metrics, identify bottlenecks, and ensure optimal operation of the server.

In conclusion, ADIC Server represents a cutting-edge solution for organizations striving to enhance data interoperability and communication. With its integration capabilities, scalable architecture, security features, and performance optimization, it stands as a dependable choice for businesses looking to leverage their data assets more effectively.
