2.
Slide the system into the rack until it snaps into place.
Cabling the system
Learn about the tasks to cable the system.
Connect the Fibre Channel or InfiniBand ports
Connect the Fibre Channel (FC) or InfiniBand (IB) ports on the storage system to your server or to a
switch.
v
A FC controller has two FC ports: A and B, on the left and right respectively. The FC ports are capable
of connecting to Point-to-Point (N-Port), Arbitrated Loop (NL-port), or Switched Fabric (F-Port)
topologies at 2-Gb, 4-Gb, or 8-Gb speeds.
v
An IB controller card has two x4 IB ports: A and B, on the top and bottom respectively. The IB ports
are capable of connecting to Quad Data Rate (QDR), Double Data Rate (DDR) or Single Data Rate
(SDR) HCAs using the SCSI RDMA Protocol (SRP).
Connecting the system to a management network
Your system includes two Gigabit Ethernet management controller port (MCP) connections for remote
management over a network.
Connect both Ethernet MCPs to the network. Do not connect only one MCP.
Attention:
There are known risks to using the FlashSystem if you only connect and configure one MCP:
v
If both MCPs are not connected and configured, an MCP failover could result in loss of system access
through Telnet, SSH or the web management GUI. Front panel access may not be available. If this loss
of access occurs, you must reboot to restore management access to the enclosure.
v
System logs and other management data are sent using the MCPs. If both MCPs are not connected and
configured, and an MCP failover occurs, these logs will not be available to assist in troubleshooting.
Connecting power to the system
A fully configured IBM FlashSystem
™
720 requires approximately 400 watts of power.
Note:
Although the system will operate when only one power supply is connected, this method is not
recommended.
