Synchronous replication will provide a zero RPO as all data is written to both the primary and secondary storage at the same time, which means any data written to the primary storage will be instantly available on the secondary storage. This configuration will ensure that the data is protected against system outage, and in case of any failure, the recovery time will be a maximum of 15 minutes as the data is already replicated to the secondary site.

iSCSI offload is a network option that can be configured to provide the best iSCSI performance on a Dell Unity XT array. This option offloads iSCSI processing to the network adapter card, reducing the load on the host CPU and improving performance. With iSCSI offload enabled, the network adapter card can handle iSCSI processing tasks such as packet segmentation and reassembly, reducing the CPU overhead associated with iSCSI operations. Other options such as using a single VLAN for all traffic, configuring jumbo frames and disabling flow control may also help to improve iSCSI performance but iSCSI offload would provide the best results. It is important to note that configuring jumbo frames could have a positive impact on performance, but it also depends on the network infrastructure and the NICs support for it. Disabling flow control could cause issues on congested networks, so it's important to test it before disabling it.
