Linux supports Matrix RAID and Rapid Storage Technology (RST) through device mapper, with dmraid tool, for RAID 0, 1 and 10. And Linux MD RAID, with mdadm tool, for RAID 0, 1, 10, and 5. Set up of the RAID volumes must be done by using the ROM option in the Matrix Storage Manager, then further configuration can be done in DM-RAID or MD-RAID. [10]
In computer data storage, Smart Response Technology (SRT, also called SSD Caching before it was launched) is a proprietary caching mechanism introduced in 2011 by Intel for their Z68 chipset (for the Sandy Bridge–series processors), which allows a SATA solid-state drive (SSD) to function as cache for a (conventional, magnetic) hard disk drive (HDD).
Sapphire Rapids is a codename for Intel's server (fourth generation Xeon Scalable) and workstation (Xeon W-2400/2500 and Xeon W-3400/3500) processors based on the Golden Cove microarchitecture and produced using Intel 7.
RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
This allows Linux to use various firmware- or driver-based RAID volumes, also known as "fake RAID". [9] As of October 2013, there are two supported formats of the external metadata: DDF (Disk Data Format), an industry standard defined by the Storage Networking Industry Association for increased interoperability.

Ceph (pronounced / ˈ s ɛ f /) is a free and open-source software-defined storage platform that provides object storage, [7] block storage, and file storage built on a common distributed cluster foundation.
An fsync request commits modified data immediately to stable storage. fsync-heavy workloads (like a database or a virtual machine whose running OS fsyncs frequently) could potentially generate a great deal of redundant write I/O by forcing the file system to repeatedly copy-on-write and flush frequently modified parts of trees to storage.
RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.
