QoS Details

This page provides information about storage medium, different institutes are planning to provide for the ESCAPE project.

In particular, we are interested about the Quality-of-Service (QoS) of this storage.
The distinction between "disk" and "tape" storage is one example of storage with different QoS. Here are some more examples:

Differences in the storage media (e.g., SSDs vs HDDs vs tape),
how data is stored (e.g., single-copy vs replication vs erasure coding) and
how files are accessed (e.g., object-store vs POSIX).
