Front-End Connectivity
Front-end connectivity provides I/O paths from servers to a storage system and replication paths from one Storage Center to
another
Storage Center. The SCv2000/SCv2020 storage system provides the following types of front-end connectivity:
Fibre Channel: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to the storage
system Fibre Channel ports through one or more Fibre Channel switches. Connecting host servers directly to the storage
system, without using Fibre Channel switches, is not supported.
When replication is licensed, the SCv2000/SCv2020 can use the front-end Fibre Channel ports to replicate data to another
Storage Center.
iSCSI: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to the storage system
iSCSI ports through one or more Ethernet switches. Connecting host servers directly to the storage system, without using
Ethernet switches, is not supported.
When replication is licensed, the SCv2000/SCv2020 can use the front-end iSCSI ports to replicate data to another Storage
Center.
SAS: Hosts or servers access storage by connecting directly to the storage system SAS ports.
NOTE: When replication is licensed, the SCv2000/SCv2020 can use the embedded REPL port to perform iSCSI
replication to another SCv2000 series Storage Center.
If replication is licensed and the Flex Port license is installed, the SCv2000/SCv2020 can use the embedded MGMT port to
perform iSCSI replication to another SCv2000 series Storage Center. In addition, the SCv2000/SCv2020 can use the
embedded MGMT and REPL ports as front-end iSCSI ports for connectivity to host servers when the Flex Port license is
installed.
SCv2000/SCv2020 Storage System with Fibre Channel Front-End Connectivity
An SCv2000/SCv2020 storage system with Fibre Channel front-end connectivity may communicate with the following
components of a Storage Center system.
