channels, labeled as channels 3 and 4. Controller B drive port pairs labeled 1 and 2 and 3 and 4 connect
to controller B drive channel 3 and 4, respectively. Each Ethernet port on a controller can have a unique
IP address; however, both Ethernet ports share the same gateway IP address and remote login settings.
The controller in the DS3950 and DS5020 controller module can have up to four host channels with one
port for each channel, up to two drive channels with two ports per channel (for a total of four drive
ports), and up to two Ethernet ports.
For controller A, the host channel identifiers are a1, a2, a3, and a4 (you will need this reference for the
CLI commands and the script commands). For controller B, the host channel identifiers are b1, b2, b3,
and b4. The following illustration shows the HBA host ports.
Controller A has one drive channel with two drive ports, labeled P1 and P2 from right to left. Controller
B has one drive channel with two ports, labeled P1 and P2 from left to right. Each Ethernet port on a
controller can have a unique IP address; however, both Ethernet ports share the same gateway IP address
and remote login settings.
The DS5300 and DS5100 controller modules can have up to eight host channels with two ports for each
channel; up to four drive channels with two ports per channel (for a total of eight drive ports); and, up to
two Ethernet ports.
For controller A, the host channel identifiers are a1, a2, a3, a4, a5, a6. a7, and a8 (you will need this
reference for the CLI commands and the script commands). The controller A host ports are numbered
from the right most port (a1) to the left most port (a8) as shown in Figure 4-10 on page 4-8. For controller
B, the host channel identifiers are b1, b2, b3, b4, b5, b6, b7, and b8. The controller B host ports are
numbered from the left most port (b1) to the right most port (b8) as shown in Figure 4-10 on page 4-8.
Note: The host ports are physically labeled on the host port covers in groups of 4 (1, 2, 3 and 4).
The HBA host ports are labeled as shown in the following figure:
