The user web interface is a bit slow, but it is really easy to use, although you still have to wait a bit when you send an operation. We have had some drive failures, but with the redundancy, we had no data loss. We just had to replace the disk, and it goes automatically well. The main difficulty is the firmware upgrade of disks, as it means stopping all the servers to make the upgrade. It would be beneficial to have it done in the background, stopping a disk and upgrading it while keeping the system running. Regarding responsiveness of the web interface, the same issue exists with iLO on the servers, where the interface is also a bit slow. However, with the new servers, it is always faster. The small CPU dedicated to that task does not have a lot of power since it is not the main task of the machine, making it less of a real problem and just a question of responsiveness.
