SAS protocol

ME4 Series SAS models use 12 Gb/s host interface protocol and qualified cable options for host connection.

12Gb HD mini-SAS host ports

ME4 Series 12 Gb SAS controller enclosures support two controller modules. The 12 Gb/s SAS controller module provides four SFF-8644

HD mini-SAS host ports. These host ports support data rates up to 12 Gb/s. HD mini-SAS host ports are used for attachment to SAS

hosts directly. The host computer must support SAS and optionally, multipath I/O. Use a qualified cable option when connecting to a host.
