Storage Clusters: Software Upgrade from 2023-01-11 21:00 CET to 2023-01-11 23:59 CET

On Wednesday 2023-01-11 and Thursday 2023-01-12, we will perform a software upgrade on our storage hosts. During this maintenance window, we expect periods of degraded performance (access time, throughput) of NVMe SSD volumes, Bulk volumes as well as our Object Storage. This upgrade will be carried out in two phases:

Phase 1: On Wednesday from 21:00 to 24:00 CET, the storage hosts at our LPG (Lupfig) region will be upgraded.
Phase 2: On Thursday from 08:00 to 11:00 CET, the storage hosts at our RMA (Rümlang) region will be upgraded.

Date / Time
Wednesday, 2023-01-11, 21:00 to 24:00 CET at our LPG (Lupfig) region
Thursday, 2023-01-12, 08:00 to 11:00 CET at our RMA (Rümlang) region

Expected Impact
We expect periods of degraded performance of NVMe SSD volumes, Bulk volumes as well as the Object Storage during this maintenance.

We apologize for any inconvenience this may cause and thank you for your understanding.
