Block Storage offered by EGI Cloud providers
Online Storage includes a wide category of services that allow users to store, share and access data using the EGI infrastructure. Different categories of storage are available, depending on how data is stored, the technology used to access and consume data, and the foreseen usage.
Three major service offerings are available:
- Block Storage is block level storage that can be attached to virtual machines (VMs) as volumes, a simple solution for durable data that does not need to be shared beside a single VM.
- Grid Storage is serving file access and storage for EGI High Throughput Compute (HTC) scenarios.
- Object Storage is persistent storage for cases when data needs to be exposed within portals or shared between different steps of processing workflows.
Comparison of storage types
The differences between Block, Grid, and Object Storage are summarized below:
|Block||Only from within VMs, only at the same site the VM is located||For the entire block||POSIX access, use as local disk|
|Grid||From any device connected to the Internet||For the data stored||Grid protocols and HTTP/WebDAV|
|Object||From any device connected to the Internet||For the data stored||HTTP requests to REST API|
The following guides offer a more detailed description of each storage service.
