Overview
The Dell™ Serial-Attached SCSI (SAS) 5 Host Bus Adapters (HBAs) are the next generation of
enterprise-class storage controllers. They are not backward compatible with the previous generation
of SCSI devices.
The SAS 5 HBAs are a half-length, full-size PCI-E card. They have four or eight serial connectors to
support Dell-compliant SAS and Serial ATA devices. The SAS 5/E Adapter communicates with the
physical disks using two x4 external connectors and the SAS 5/i Integrated communicates using a
x4 internal SAS connection.
The SAS 5 HBAs are supported on platforms with PCI-E x8 or x16 connectors.
