I know tha AFF and FAS series, can direct attach with iscsi protocol. My question is, is the same for AFF ASA?, this series include symmetric active-active and i don't know if remaining direct attach option
You can direct-attach iSCSI or NVMe/TCP to any of our platforms. However, this is generally discouraged because it severely limits scaling and may not have sufficient redundancy. You must have a switch for FC because we rely on NPIV services from the switch to support multiple LIFs on a single physical port.
