QRIScloud NeCTAR users are advised that on March 17th and 18th there will be
a series of rolling outages affecting a large number of QRIScloud
NeCTAR instances. These outages will allow us to make important hardware
upgrades as part of QCIF's regular program of QRIScloud / NeCTAR service
improvement. Specifically, 23 out of 54 of QRIScloud's general compute
nodes are going to be fitted with new Solid State Drives (SSDs) purchased by NeCTAR. This
will allow more instances to be run on these nodes, increasing the
overall capacity of QRIScloud.
The upgrade work will be performed progressively, with 1 or 2 compute nodes out of service at any one time. The planned procedure for each compute node is as follows:
3 weeks ago, we sent emails to the Tenant Managers and Tenant Members for all instances that will be affected by the outages. Reminders are being sent today, and we plan to send a one-day warning on Wednesday 16th. These emails include some advice on precautions that users should take to prior to the outage.
We cannot give a precise schedule for the outages, but we will use the @QRIScloud twitter feed to post updates as the upgrade progress.
If you have concerns about the impact of these outages, please contact QRIScloud support; <firstname.lastname@example.org>
