In-Band
Management and
Out-of-Band
Management
A system administrator manages a storage array from a storage management station,
which is a workstation on which the SANtricity ES Storage Manager Client is
installed. Requests and status information sent between the storage array and the
storage management station are managed in one of two ways: in-band or out-of-band.
A storage array that uses out-of-band management requires a different network
topology from a storage array that uses in-band management.
When you use in-band management, a SANtricity ES Storage Manager agent running
on the host receives requests from the management station. The host agent processes
the requests through the host I/O interface to the storage array. The host I/O interface
might be Fibre Channel, serial-attached Small Computer System Interface (SAS),
InfiniBand, or Internet SCSI (iSCSI).
