With implementations that are solely volume management, such as Core Storage and Linux LVM, separating and abstracting away volume management from the file system loses the ability to easily make storage decisions for particular files or directories. For example, if a certain directory (but not the entire file system) is to be permanently moved ...
In Linux, Logical Volume Manager (LVM) is a device mapper framework that provides logical volume management for the Linux kernel. Most modern Linux distributions are LVM-aware to the point of being able to have their root file systems on a logical volume. [3] [4] [5]
ESOS is a niche Linux distribution. ESOS is intended to run on a USB flash drive, or some other type of removable media such as Secure Digital, CompactFlash, etc. ESOS is a memory resident operating system: At boot, a tmpfs file system is initialized as the root file system and the USB flash drive image is copied onto this file system.

A tape file system is a file system and tape format designed to store files on tape. Magnetic tapes are sequential storage media with significantly longer random data access times than disks, posing challenges to the creation and efficient management of a general-purpose file system.
ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
Hierarchical storage management (HSM), also known as tiered storage, [1] is a data storage and data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid-state drive arrays, are more expensive (per byte stored) than slower devices ...
One or more object storage server (OSS) nodes that store file data on one or more object storage target (OST) devices. Depending on the server's hardware, an OSS typically serves between two and eight OSTs, with each OST managing a single local disk filesystem. The capacity of a Lustre file system is the sum of the capacities provided by the OSTs.
High Performance Storage System (HPSS) is a flexible, scalable, policy-based, software-defined hierarchical storage management (HSM) product developed by the HPSS Collaboration. It provides scalable HSM, archive, and file system services using cluster, LAN and storage area network (SAN) technologies to aggregate the capacity and performance of ...
