Channel
Select the Host Channel for mapping the Volume Set. Options are: SATA (CH0), USBiA
(CH1), and SATA&USBiA.
NOTE: Select “SATA (CH0)” channel when Volume Set will be mapped
to eSATA Port0 or eSATA Port1. Select “USBiA (CH1)” channel when
Volume Set will be mapped to USB Port or accessed via iSCSI/AoE.
Drive #
For eSATA Port0, Drive # options are 0 to 7 (The drive# is assigned in order).
For eSATA Port1, Drive # options are 8 to 15 (Manual Assignment).
For USB Port, Drive # options are 0 to 7.
For iSCSI/AoE, Drive # options are 8 to 15.
NOTE: The eSATA HBA or controller in the host system must support
port multiplier to recognize Volume Sets mapped as Drives 1 to 7
and 8 to 15. Example of eSATA controllers that support port
multiplier are Sil3132 or 3124 and Intel ICH9 or ICH10.
Host Channel Port The Maximum Number of Volume Sets
eSATA Port0 8
eSATA Port1 8
USB 2.0 Port 8
iSCSI/AoE (R-Link Port) 8
IMPORTANT! It is not recommended to use iSCSI together with
eSATA/USB at the same time since access to Volumes can be
slower than normal. Using eSATA and USB at the same time is ok.
NOTE: In order to maintain the system I/O performance, it is not
recommended to access the storage from the different host
interfaces at the same time.
