Serial Attached SCSI Host
Astra ES models can have one or two RAID controllers. Each controller has an Ethernet (RJ45) Management Port connector that enables you to monitor the Astra ES over your network using the Astra ES Management GUI Software. Astra ES supports HTTP(S) and Telnet protocols.
The standard Astra ES SAS Host controller has three SAS ports:
•Data port – Connects to the Host PC or Server
•Data/Cascade port – Connects to the data port of a second Astra ES SAS controller or to the Host PC or Server
•SAS Expansion port – Connects to a Astra ES JBOD expansion subsystem
You can configure your Astra ES for:
•Direct Attached Storage (DAS)
•Cascaded Storage (Multiple Astra ES subsystems)
•JBOD Expansion using a SAS data connection

Configuring Direct Attached Storage
Direct attached storage (DAS) requires:
•Two SAS HBA cards in the Host PC or Server
•A network switch
•A network interface card (NIC) in the Host PC or Server
To establish the data path:
On the Astra ES controller, connect a SAS data port or a SAS data/cascade port to one of your SAS HBA cards.
To establish the management path:
1.On the Astra ES controller, connect the Management Port on each Controller to your network switch.
2.Connect the Host PC’s or Server’s standard NIC to your network switch.
