Storage Configuration (SE)

Storage Device Convention

Seda keeps to a consistent naming scheme for file systems on systems deployed in the field or locally. This page explains those conventions so that you can understand what each file system is and why it is given a specific name.

Arc

Arc (or Archive on earlier builds) is a name given to filesystems where you will store the data and not access it very often. This is usually used for long-term storage or backup storage.

Array

An Array is a RAID configuration of three or more disks set up with some redundancy. If a system has an Array, it will be the default location for all data to be stored. The Array configuration Seda deploys is RAID5, which can survive a single disk failure without loss of data. Two disks failing loses everything.

Aux/Asx

Aux is a name given to either a standalone drive or RAID0 configuration - no redundancy - set up for maximum speed. These are often used for running games or other data where speed is more valuable than safety. Note that on Windows systems, this will be named Asx due to limitations of the operating system.

Core

A Core drive is the first single-disk storage volume on the system. If the system only has a single disk, it will be called Core. This applies to all operating systems. If it is the only drive in the system, it can be a Solid State Drive (SSD) or a Hard Disk Drive (HDD). If it is not the only drive in the system, it will almost certainly be a Hard Disk Drive (HDD). If the system does not have an Array, most data will be stored on Core.

Root

A Root drive is used where a system will have more than one disk. For example, if you have a single disk with Windows and a secondary disk for your documents, the Windows disk is a Root disk, and your secondary drive would be Core. The Root drive will be named after the operating system you are running, which is either Debian or Windows on systems deployed by Seda. By default, Seda will configure your system not to use the Root disk aside from the operating system itself - everything will be stored on Core instead. This means that if your operating system fails, your data will be otherwise unaffected.

Storage Order

If an Array is present, it will be used.
If no Array is present, Core will be used.
If no Array or independent Core is present, Root will be known as Core and will be used.

Aux and Arc are special file systems and will never be used as primary storage.
