Unlocking the Power of Storage with Linux TGTD Technology（linuxtgtd）

Recently Linux kernel 4.11 introduced the target driver subsystem, or TGTD. It is based on the Linux iSCSI Target driver and provides a powerful storage framework that is pluggable, extensible, and user friendly.

The target driver subsystem provides a multi-level, distributed, hardware independent way to manage storage devices, from flash memory to spinning disks to SAN and NAS systems. It provides mechanisms for communication, configuration, and management of the storage devices.

The TGTD allows Linux devices to create and manage a target, a logical block device that acts as a unified storage system for data. The TGTD also enables the creation of thin provisioning, where space is allocated to store a file only when needed. It provides multiple functions from basic read/write to snapshotting, mirroring and cloning.

The key advantage of the TGTD is its ability to provide storage services in user-space, thus eliminating the need for specialized drivers and software to perform storage operations. By using TGTD, admins and developers can interact with storage devices in the same way they interact with files and can easily modify their existing applications to take advantage of the features provided.

The TGTD technology is a great way to unlock the power of storage and simplify it with a seamless, user-friendly interface. It eliminates the need for specialized storage, simplifies storage configurations and administration, and provides multiple storage-related operations.

Let’s take a look at a real world example of how TGTD technology can be used. Suppose you have a web server that uses a variety of Apache and Node.js applications, backed by a single storage server.

You can use TGTD to provision a Target for each application, so that it can create a dedicated storage space for each web application, resulting in improved performance. With the TGTD, provisioning is much simpler and data protection is improved because each application has its own storage space.

You can also apply TGTD to handle data synchronization across devices in a large-scale, fault tolerant environment. For example, a company could use TGTD to enable replication between servers, with storage devices managed in a shared storage cluster. This way, you can build a flexible, efficient, highly available storage system that is easy to manage and maintain.

TGTD technology is one of the more exciting new storage framework technologies to emerge in the Linux space. It allows simplifying storage operations and administration and provides powerful features to ensure the best storage solutions available. Whether you are looking to improve web application performance or to build a highly available storage system, TGTD can help.
