The FC SAN network must support 16/32 Gb/s link speed on all components: HBAs, SAN ports, and Unity XT front-end 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 using these ISLs. An SAP HANA node requires the maximum bandwidth of 400 MB/s.
Connecting the SAP HANA nodes using NAS (NFS) requires:
When IP switches are connected using uplinks, the aggregated bandwidth of the uplinks must be able to support the aggregated total bandwidth of all the SAP HANA nodes that are using these uplinks. An SAP HANA node requires the maximum bandwidth of 400 MB/s.
