For FC connectivity, configure dual redundant fabrics with each PowerStore node and each external host having connectivity on each of the fabrics. Minimize the number of hops between host and PowerStore. For performance, load balancing, and redundancy, each host must have at least two paths to each PowerStore node (four ports per PowerStore appliance). Dell Technologies recommends that a host has no more than eight paths per volume.
For SAP HANA hosts, the FC SAN network must support a minimum of 16 Gb/s speed on all components—HBAs, SAN ports, and PowerStore FE I/O modules. When SAN switches are connected using Inter-Switch Links (ISLs), the aggregated bandwidth of the ISLs must be able to support the aggregated total bandwidth of all the SAP HANA nodes that are using these ISLs. To meet SAP HANA KPIs, an SAP HANA node requires the maximum bandwidth of 400 MB/s.
