10.2 Preparing Controllers
10.2.1 Requirements:
Cabling Requirements:
Communications Channels:
- Controller Communications (Cache Synchronization) Paths:
Controller RCC cable
SentinelRAID A SCSI cable (CH 0)
EonRAID 2510FR Dedicated RCC or RCC over drive loops
EonStor Pre-configured RCC routes over the system
backplane
- 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.
