What: We will be upgrading the network of our Sydney Enterprise Cloud Availability Zone to enhance the functionality, stability, maintainability and performance for all customer services.
The upgrade involves implementing Brocade's industry leading low-latency VDX series Ethernet switches. Brocade VDX switches feature Brocade's self-healing Ethernet fabric technology known as VCS ().
Brocade VDX switches also feature advanced Software Defined Networking (SDN) capabilities. Information on Brocade VDX, VCS and SDN can be found at http://www.brocade.com/products/all/switches/
Why: This maintenance is being undertaken to improve the resiliency, performance and serviceability of our Sydney Enterprise Cloud Zone. The upgrades also prepare us for introducing advanced SDN features which will become available later this year.
When: Saturday May 9th 2015 : 8pm - 11:45pm AEST
Impact: Network connectivity will be disrupted during the maintenance window. Whilst we will be 'cutting across' one device at a time we cannot guarantee that network connectivity will not be interupted. As a result CloudCentral recommends that customers shut down their VM instances during the maintenance window to avoid storage timeouts and IO errors.
CloudCentral will contact services with Managed Cloud Service agreements individually to make the necessary arrangements to minimise disruption to your services.
