and objectives

The objective that HKU set out was to migrate from SUSE Enterprise Storage (SES) to an open-source Ceph version with open source support.

Find another support solution

SUSE announced they would stop supporting Ceph. As SES was a service that HKU applied, they needed to find another support solution and seek advice based on support options.

Migrate current Ceph version

They also wanted to migrate their current Ceph version to one of the latest Ceph versions.

Move from SES support

HKU set out to move from their current SES support to 42on Emergency Assistance Ceph support.

Keep SUSE as underlying OS

They wanted to keep SUSE as the underlying OS in order to avoid creating more complexity.

No hick-ups or downtime

Because a lot of students rely on the Ceph backbone, the objective for HKU was to conduct this migration without any hick-ups or downtime in the environment.
