Question: What type of storage is primarily used for storing the boot volume of an instance in the oracle cloud infrastructure compute service?
If you are using the Oracle Cloud Infrastructure Compute service, you might be wondering what type of storage is primarily used for storing the boot volume of an instance. In this blog post, we will explain the different options and benefits of each one.
A boot volume is a block storage device that contains the operating system and any other software required to boot and run an instance. Boot volumes are attached to instances as virtual devices and are persistent, meaning that they retain their data even after the instance is stopped or terminated.
There are two types of boot volumes in Oracle Cloud Infrastructure: local NVMe SSDs and block volumes. Local NVMe SSDs are physically attached to the compute host and offer high performance and low latency. Block volumes are network-attached storage devices that can be dynamically provisioned and scaled up to 32 TB. Block volumes offer durability, availability, and backup capabilities.
The type of boot volume that is primarily used for an instance depends on the shape of the instance. A shape is a template that determines the number of CPUs, amount of memory, and other resources allocated to an instance. Some shapes support only local NVMe SSDs as boot volumes, while others support only block volumes. Some shapes support both types of boot volumes and allow you to choose which one to use when launching an instance.
