Storage Volumes

Boot Volumes

Nirvana storage volumes are engineered to deliver significantly higher performance than similar elastic block storage solutions. The boot volume forms the foundation of the operating system in your Virtual Machine. It is a dedicated storage unit where the bootable operating system, system files, and data needed during the system start-up process are stored. Just like a physical computer's hard drive stores the essential files, the boot volume serves the same purpose in a VM.

Nirvana Cloud's boot volumes are designed to handle high-intensity input/output operations and deliver superior performance. It ensures that even demanding applications boot up effortlessly and function smoothly.

Data Volumes

Beyond the boot volume, a VM's storage capacity can be expanded by utilizing multiple data volumes.

Depending on the VM's operational needs, multiple data volumes can be added to or removed from a VM in order to increase or decrease the amount of storage.

Common Use Cases for Multi-Volume Deployments:

• Separating the boot volume from the data volume for better performance and easier management.
• Adding additional volumes to a VM for more storage space.
• Utilizing raid configurations for better performance and redundancy.
• Creating separate volumes for different applications or services running on the VM.
• Storing blockchain snapshots temporarily on a second volume and removing that volume after the snapshot extraction is complete.

Things to Keep in Mind:

• Volumes can only be expanded, not shrunk. Make sure to back up any important data before expanding a volume to avoid data loss.
• When adding or removing a volume from a VM, the VM will be stopped while the volume is being added or removed and will be started again once the add/remove operation is complete.
• Make sure to unmount the volume and update the fstab file before removing a volume to avoid boot issues.
• After expanding a volume, make sure to resize the filesystem on the volume to make use of the additional space.

Understanding NVME

NVMe (Non-Volatile Memory Express) is a groundbreaking communications interface and driver that leverages the high bandwidth of PCIe. Crafted to elevate performance, efficiency, and interoperability, NVMe is set to become the industry's new standard for SSDs.

As the demands of applications like Web3 and blockchain surge, NVMe's capabilities ensure that Nirvana Cloud remains at the forefront of storage solutions.
