The departmental GPU cluster will be undergoing maintenance in order to maintain its security and reliability.
This will affect:
Personal GPU development VMs, dev-gpu-*
Personal CPU development VMs, dev-cpu-* (if they are running on the GPU cluster, as most are)
Shared GPU development servers dev-gpu-2, dev-gpu-acs
Shared CPU development server dev-cpu-1
Access to GPU cluster storage from other systems (/anfs/gpucluster, /anfs/gpudata, /anfs/gpuscratch)
Affected personal VMs will be shut down at the start of the maintenance and cannot be started again until it is finished.
Shared servers will be rebooted during the maintenance.
During the maintenance we will be installing some updates on both the VM hosts (important hypervisor security improvements) and on the storage platform (NFS reliability improvements). We will also be performing a hardware upgrade on the storage platform to enable future capacity expansion (power supply upgrade, required before we can add any more SSDs to the server).
