Operating Guidelines

When operating AMASS 5.4, please make note of the following operating guidelines.

IRIX: Tape Support (TS) system

The tape support (TS) system consists of a tape support driver, personality daemons, and a daemon to manage the personality daemons. Thie TS system is provided by SGI to manage tape devices. AMASS does not require the TS system to run and it has trouble if the TS system is controlling the AMASS drives. The mediad daemon initiates the ts daemon on the AMASS drives. To disable the ts daemon, change the mediad configuration, /etc/config/mediad.config, so that the mediad daemon ignores the AMASS drives.

Solaris: Shared Memory

AMASS may require more shared memory than the default size allocated on your operating system. If this happens, the following message appears.

AMASS shared memory size of 1692944 bytes exceeds current system limit. Error getting shared memory via shmget, errno 22 - Invalid argument.

Workaround:

1Refer to the man page for system (4) on Solaris.

2Set the value for shmsys:shminfo_shmmax in the /etc/system file to a number that is large enough to accommodate AMASS and other processes on your system.

3Reboot the Solaris machine.

Solaris: FTP

Customers may experience poor performance in writing/reading from AMASS via ftp. The problem is the size of the IO request issued and the amount of IO buffering at the OS level between the application and AMASS kernel. This could exist for applications other than FTP as well.

To get better performance use an alternative FTP daemon which can be configured to write/read from AMASS with larger block sizes. WU FTPD is one option. A customer may also experience poor performance with a FTP client. Please contact ATAC for details.

All: Scalar DLC

AMASS may experience a problem with loading media into the S10K (with Scalar DLC). The drive types are AIT, but Scalar DLC looks for 8mm for the mount rather than AIT due to a mismatch in parameters. The XDI utility sends the drive type AIT rather than 8mm on the mount.

Note

This procedure is for Scalar DLC 2.x only.

 

Workaround:

1On the Scalar DLC box, select Configuration > Clients.

2Select the AMASS DAS client entry.

3Select the aliasing tab.

4Change the media type to sony_ait on the media type alias entry.

5Restart Scalar DLC.

6Follow the mount procedure as usual.

5.4 specifications

ADIC 5.4 is the latest iteration of the Advanced Data Integrity Checker (ADIC), designed to bolster data security and ensure reliability in digital ecosystems. This version introduces a host of features and technologies that enhance the robustness of data management systems across various industries.

One of the most significant features of ADIC 5.4 is its advanced error detection and correction capabilities. Utilizing sophisticated algorithms, this tool can identify discrepancies in data integrity caused by corruption, unexpected changes, or malicious tampering. By promptly flagging these issues, ADIC minimizes the risk of data loss and ensures that organizations can maintain high standards of reliability.

Another key characteristic of ADIC 5.4 is its integration with Artificial Intelligence (AI) and Machine Learning (ML). These technologies allow the system to learn from previous data patterns, improving its detection and correction efficiency over time. By leveraging AI, ADIC can predict potential vulnerabilities, providing organizations with actionable insights to preemptively address data risks.

ADIC 5.4 also boasts enhanced compatibility with cloud-based environments. As more businesses migrate to the cloud, the need for tools that can seamlessly integrate and secure data stored in decentralized locations becomes critical. ADIC 5.4’s multi-platform support ensures that users can validate data integrity, regardless of where it resides, whether in on-premises systems or across multiple cloud providers.

Furthermore, the user interface has been revamped for better usability, featuring intuitive dashboards that present complex data insights in an easily digestible format. This allows users of varying expertise levels to navigate the system efficiently, promoting quick decision-making in critical situations.

The implementation of real-time monitoring within ADIC 5.4 is another noteworthy characteristic. This enables organizations to receive immediate alerts on data integrity issues, allowing for swift remediation actions. The system’s ability to generate comprehensive reports aids in compliance with regulations and internal policies, supporting organizations in maintaining transparency and accountability.

In summary, ADIC 5.4 represents a pivotal advancement in data integrity verification technologies. With its powerful error detection, AI integration, cloud compatibility, improved user interface, and real-time monitoring capabilities, it provides organizations with the tools necessary to safeguard their data assets effectively. As data security remains a paramount concern, solutions like ADIC 5.4 are essential for maintaining trust and efficiency in digital operations.
