Is the storage throughput (IOPS) in the bwCloud throttled?[faq_storage_1]

Yes. Due to the internal architecture all data (root discs of the instances, attached storage volumes etc.) are stored in the ceph memory of the respective region. Ceph is a network-based distributed storage system, which is internally connected to the compute hosts via network. The available storage throughput is therefore distributed to all active users. The more parallel writes that take place, the more the data throughput for each individual user decreases. Which is quite logical, because network capacity and bandwidth are limited overall.

In order to offer equal performance to all users, the memory throughput per instance is limited to either 100 MByte per second in both directions (full duplex) or to 800 IOPS.

But I need more data throughput for my application[faq_storage_2]

If the request is justified, users can ask for more data throughput. Please send us a ticket at In the ticket you tell us the following points:
a) You want to get more data throughput
b) description of the use case or application: Why do you need more data throughput?
c) OpenStack identification (ideally the User-ID)
d) In which region do you need more data throughput?

The points a) to d) are mandatory information

increase IOPS, storage, throughput, QoS, network capacity, bandwidth
