Block Storage

Key questions and answers about block storage in the Safe Swiss Cloud.

  • What is Block Storage used for?

    Block Storage is used for storing data in a variety of application areas, particularly in enterprise environments such as data centers, cloud computing platforms, and virtualized environments. Some of the most common use cases for block storage include:

    1. Databases: Block storage is frequently used for storing databases, particularly relational databases such as Oracle or Microsoft SQL Server. It provides fast access to data and enables efficient management of databases.
    2. High-performance computing: Block storage is also very useful in HPC environments, where fast and efficient storage of data is required to run complex scientific and engineering applications.
    3. Virtualization: Block storage is often used to store virtual machines (VMs) in a virtualized environment. It enables rapid creation, copying, and moving of VMs and improves the scalability of virtualized environments.
    4. Cloud computing: In cloud computing platforms, block storage is frequently used to provide storage space for applications and services. It offers scalable, flexible storage space that can be adjusted as needed.
    5. Backup and disaster recovery: Block storage is also often used as a target for backup and recovery solutions, as it provides high reliability, recoverability, and security.

    Overall, block storage provides an effective and scalable way to store and manage data, and has become essential for a variety of application areas.

  • What is Block Storage?

    Block storage is typically used in cloud computing environments to provide storage volumes (disk sized chunks of storage) for virtual machines. The virtual machines (VMs) use these block storage volumes the way a disk is traditionally used, e.g. to install the operating system, software programs, store data etc. Typically a VM will have at least one storage volume which is a dedicated allocation in a pool of block storage.

    Block storage is a type of data storage that manages data as blocks or chunks of fixed sizes, typically ranging from a few kilobytes to several megabytes. Each block is assigned a unique identifier, and these blocks are organized and accessed in a specific order, often in the form of a block address or a logical block number (LBN).

    Block storage is commonly used for storing data in enterprise storage environments, such as in SAN (storage area network) and NAS (network-attached storage) systems, and for providing storage for virtual machines and cloud computing. Unlike file storage, which organizes data as files and folders, block storage operates at a lower level, providing raw storage volumes that can be formatted with any file system or used for low-level disk access.

    One of the advantages of block storage is its flexibility and scalability. It can be easily expanded by adding more storage blocks or disks, and it provides fast, efficient access to data, making it suitable for high-performance applications and database management systems.

    Block storage is also known for its reliability and data protection features. Data can be replicated across multiple disks or nodes to ensure redundancy and data integrity, and data recovery and backup processes can be easily implemented to protect against data loss or corruption.
