Galaxy GHDX4 RAID iSCSI-SAS/SATA InstaHardware Reference Manual
66
SAS and SATA drives come with different capacities. Do not
include drives of different capacities in a logical drive.
Otherwise, some part of the larger drives’ capacity will be
wasted. Our firmware always uses the maximum capacity of
the smallest drive as the standard capacity of all member
drives when composing a logical drive.
SAS WWN addresses
:
SAS expansion links are made via SAS expander chips,
and there are specific WWN addresses for the devices
connected through these chips. When making
expansion, make sure you select a unique ID using the
rotary switch on JBOD.
Enclosure ID Configuration
Please note that the JBOD enclosure ID always starts
from “
1
.” Setting an ID to “
0
” may cause address
conflicts with those already occupied by SAS expander
chips.
Powering On
Once all the components have been installed in the Galaxy
subsystem, the iSCSI ports have been connected to the network,
power on the network devices, the subsystem, and then power on the
servers/iSCSI initiators.
