10.2 Preparing Controllers

10.2.1 Requirements:

10-14

Cabling Requirements:

Communications Channels:
Controller Communications (Cache Synchronization) Paths:
-
Controller
SentinelRAID
EonRAID 2510FR
EonStor
Using one or two of the I/O channels for controller communications
-
(as listed above) is necessary especially when write-back caching is
preferred. If controllers are running in write-back mode, a battery
module is recommended for each controller.
-
Use the default channel (CH 0) for the SentinelRAID controllers.
-
Out-of-Band Configuration
RS-232C cable (for Terminal Interface Operation) connection.
-
Ethernet connection: If management through Ethernet is preferred,
-
connect the Ethernet interface from both controllers to ports on a hub.
The IP address assigned to one controller will be inherited by the
surviving controller.
Host and Drive Connection
-
All channels on one controller must be connected to the same channels
-
on its counterpart.
RCC cable
A SCSI cable (CH 0)
Dedicated RCC or RCC over drive loops
Pre-configured RCC routes over the system
backplane
