Figure 1-6 Storwize V5010 node canister
Each Storwize V5010 node canister contains the following hardware:
Battery
Memory: 8 GB
One 12 Gbps SAS port for expansions
Two 10/100/1000 Mbps Ethernet ports
One USB 2.0 port that is used to gather system information
System flash
Host interface card (HIC) slot (different options are possible)
Figure 1-6 shows the following features that are provided by the Storwize V5010 node
canister:
Two 10/100/1000 Mbps Ethernet ports. Port 1 must be used for management, and port 2
can optionally be used for management. Port 2 serves as a technician port (as denoted by
the white box with "T" in it) for system initialization and service.
Note: All three models use a technician port to perform initial setup. The
implementation of the technician port varies between models: On Storwize V5010/20
the second 1 GbE port (labelled T) is initially enabled as a technician port. After cluster
creation, this port is disabled and can then be used for I/O or management.
On Storwize V5030 the onboard 1 GbE port (labelled T) is permanently enabled as a
technician port. Connecting the technician port to the LAN will disable the port. The
Storwize V5010/20 technician port can be re-enabled after initial setup.
The following commands are used to enable or disable the technical port:
satask chserviceip -techport enable -force
satask chserviceip -techport disable
Both ports can be used for iSCSI traffic and IP replication. For more information, see
Chapter 5, "Host configuration" on page 199 and Chapter 10, "Copy services" on
page 485.
One USB port for gathering system information.
System initialization: Unlike the Storwize V5000 Gen1, you must perform the system
initialization of the Storwize V5010 by using the technician port instead of the USB port.
One 12 Gbps serial-attached SCSI (SAS 3.0) port to connect to the optional expansion
enclosures. The Storwize V5010 supports up to 10 expansion enclosures.
