According to the HPE SimpliVity documents and learning resources, the best practice for designing an HPE SimpliVity solution is to use nodes with the same drive configuration and capacity within a cluster, and avoid mixing All-flash and hybrid nodes, or nodes with different drive types, sizes, or speeds. This is because mixing nodes with different drive configurations can result in unbalanced 10 performance and capacity utilization, as well as compatibility issues.Therefore, the recommended option for this design is to create a new cluster with HPE SimpliVity 380 Gen10 H SFF nodes at the remote site, and keep the existing cluster with HPE SimpliVity 380 Gen10 hardware accelerated nodes at the primary site. The other options are incorrect because they do not follow the best practice and can cause performance and capacity problems. References: Using HPE SimpliVity Official Certification Study Guide, page 42; HPE SimpliVity networking explained; HPE SimpliVity Releases

• HPE SimpliVity is a hyperconverged infrastructure solution that combines compute, storage, networking, and data services in a single platform. HPE SimpliVity integrates with HPE StoreOnce, a disk-based backup appliance, to provide efficient and reliable data protection and disaster recovery for distributed edge sites12.
• HPE SimpliVity uses HPE StoreOnce Catalyst, a deduplication protocol, to replicate data from HPE SimpliVity clusters to HPE StoreOnce appliances. HPE SimpliVity leverages its global deduplication and compression capabilities to send only the unique data blocks to HPE StoreOnce, reducing the bandwidth and storage requirements34.
• To optimize the replication performance, HPE SimpliVity uses a dynamic stream allocation algorithm that determines how many streams it needs to copy data to an HPE StoreOnce target. According to the HPE SimpliVity with HPE StoreOnce Reference Architecture document, the algorithm considers the following factors:
• The document states that “The available bandwidth is the most important factor in determining the number of streams. The more bandwidth available, the more streams can be used to copy data. However, the number of streams is limited by the latency and the size of the data. If the latency is too high or the data size is too small, adding morestreams will not improve the performance.” Therefore, the available bandwidth is the criteria that HPE SimpliVity uses to decide how many streams it needs to copy data to an HPE StoreOnce target.
