Storage connectivity design considerations
UCS storage physical connectivity has a slightly different design consideration as compared to LAN physical connectivity. The following are some design considerations for SAN connectivity:
- Northbound storage physical connectivity does not support vPCs like LAN connectivity, where you can have cross-connected vPCs for redundancy.
- Port channels or trunking is possible to combine multiple storage uplink ports that provide physical link redundancy.
- Redundancy of storage resources is handled by the storage itself and varies from vendor to vendor including active-active, active-passive, Asymmetric Logical Unit Assignment (ALUA), and so on.
