Single VM Thick Provisioned – Initial testing was conducted using VM #2, which is 40 GB on disk as shown in Figure 24. IIS and Visual Web Developer were installed on the server. Un-optimized, 8.1 GB of data was transferred in 21 minutes. Optimized, 2.5 GB of data was transferred in 15 minutes. Figure 24: VMware Initial Replication 40 GB Thick Provisioned – Shown in Figure 25: is the Bandwidth optimization report shows a 68.5 percent data reduction on this test, resulting in 3.2x effective increase in network carrying capacity. Figure 25: VMware Initial Replication 16 GB Thin Provisioned – Multiple VMs A test was conducted for initial replication of all virtual machines. Overall, as in Figure 26, replication time was decrease by more than half, and 72 percent of the data was removed from the transfer. Figure 26: VMware Initial Multiple VMs – The Bandwidth Optimization report from the Azure SteelHead for this test is shown in Figure 27. Figure 27: VMware Initial Multiple VMs – Overall Conclusions Azure Site Recovery brings down the CAPEX and OPEX costs of a disaster recovery solution by enabling customers to protect their workloads to Microsoft Azure. A key component of this solution is around provisioning the network appropriately to ensure that the RPO goals are met. It is also important to ensure that the impact to the organization’s Internet bandwidth is kept to a minimum. Riverbed SteelHead’s WAN optimization technology plays a crucial role in meeting this twin objective. With an industry-first Azure optimization appliance, the Riverbed SteelHead appliance provides significant savings on the Internet bandwidth. This paper illustrated the savings in a controlled environment running synthetic workloads which represent real-world applications and the savings are very evident. – The two key takeaways are:
