The main requirement from Ascentis was to ensure the replication happened in an acceptable timeframe to deliver daily snapshots within a few hours maximum, even if the entire volume needed to be replicated.
Slower replications lead to several issues that can cause business disruption: snapshots potentially piling up; over consumption of the link between Uruguay and the US; and lack of a workable DR strategy while virtual machines in both sites drift apart.
Due to the geographical distance between the sites, the connection wasn’t ideal at 60Mbps with over 200ms latency. Bandwidth was good but TrueNAS SSH+NETCAT replication protocol doesn’t work well with high latency networks.
“Replify allowed us to implement a D/R strategy based on TrueNAS as a source for iSCSI storage. The situation was pretty simple: without the incredible boost provided by Replify it was going to be impossible for us to utilize TrueNAS as a replication platform given the geographical distance between our datacenters.”
