What is a block volume?

What is a block volume?

Block volume: A detachable block storage device that allows you to dynamically expand the storage capacity of an instance. Boot volume: A detachable boot volume device that contains the image used to boot a Compute instance. See Boot Volumes for more information.

What is block volume performance units?

Oracle Cloud Infrastructure New feature – Block Volume Elastic Performance. VPU = Volume performance units. You can purchase more VPUs to allocate more resources to a volume, leads to increased IOPS/GB and throughput per GB.

What is OCI block volume?

Oracle Cloud Block Volumes provide customers reliable, high-performance block storage designed to work with a range of virtual machines and bare metal instances. With built-in redundancy, Block Volumes are persistent and durable beyond the lifespan of a virtual machine and can scale to 1 PB per compute instance.

What are three key characteristics of block storage volumes?

They can be detached from one compute instance and attached to another in a different Availability Domain. They can be backed up to the Object Storage Service. They can be cloned. They can be suspended while not in use to avoid paying for utilization.

How do I access block level storage?

Block level storage presents itself to servers using industry standard Fibre Channel and iSCSI connectivity mechanisms. In its most basic form, think of block level storage as a hard drive in a server except the hard drive happens to be installed in a remote chassis and is accessible using Fibre Channel or iSCSI.

How do I access OCI object storage?

OCI Object Storage can be accessed via Command Line Interface (CLI), Console, Java SDK, or REST API. Within the console, the new Cloud Shell provides access to an always-available Linux shell directly in the OCI Console.

Which elastic performance option should you choose for the block volume?

Balanced: The default performance level for new and existing block and boot volumes, and provides a good balance between performance and cost savings for most workloads.

What is OCI logging?

Oracle Cloud Infrastructure Logging. Built on open standards, OCI Logging is an intuitive, centralized platform for all types of logs, such as audit, infrastructure, database and applications, which are needed for DevOps and security compliance.

What is difference between object storage and block storage?

With block storage, files are split into evenly sized blocks of data, each with its own address but with no additional information (metadata) to provide more context for what that block of data is. Object storage, by contrast, doesn’t split files up into raw blocks of data.

What is the difference between boot volume and block volume?

What is block leveling?

Block-level storage is a concept in cloud-hosted data persistence where cloud services emulate the behaviour of a traditional block device, such as a physical hard drive. Block-level storage is in contrast to an object store or ‘bucket store’, such as Amazon S3 (simple storage service), or to a database.

What is block volume in Oracle Cloud Infrastructure?

A common usage of Block Volume is adding storage capacity to an Oracle Cloud Infrastructure instance. After you have launched an instance and set up your cloud network, you can create a block storage volume through the Console or API. Then, you attach the volume to an instance using a volume attachment.

What are the benefits of block volume?

Additionally, Block Volume volumes offer a high level of data durability compared to standard, attached drives. All volumes are automatically replicated for you, helping to protect against data loss, see Block Volume Durability.

How do I read and write data from a block volume?

When you attach a block volume, you can specify one of the following options for access type: Read/write: This is the default option for volume attachments. With this option, an instance can read and write data to the volume.

How do I connect to a volume from an instance?

After the volume is attached, you connect to the volume from your instance’s guest OS using iSCSI . The volume can then be mounted and used by your instance. A Block Volume volume can be detached from an instance and moved to a different instance without the loss of data.
