CMG Financial on High Availability

Jerry Nihen, Senior Systems Engineer at CMG Financial on the key SoftNAS HA benefits over traditional file system HA solutions.


Single availability zone solution offering 99.9% HA with 2 SoftNAS controllers sharing a single copy of the data in block storage. A single HA IP address called a Virtual IP (VIP) routes the client traffic to the Primary SoftNAS controller. This solution saves 50% on HA costs by eliminating redundant block storage in a different availability zone.  


Two availability zone solution offering 99.999% HA with 2 SoftNAS controllers replicating the data into block storage in both availability zones. A single IP address called a Virtual IP (VIP) routes the client traffic to the current Primary SoftNAS controller. The Primary controller replicates data changes to the Secondary controller, which runs in a separate zone with its copy the block storage.
