Table 22. Utility patch panel connections (continued)
Patch panel port Component Description
VPN (remote support) ports Grid controllers 3, 4 These two virtual private network (VPN) ports are used
to connect to the IBM FlashSystem Remote Support
Center.
Note: Use both VPN connections for redundancy to
avoid losing remote support if one of the grid
controllers fails.
Tech (technician) ports Grid controller 1 (For technician use only.) This port is used by the IBM
service representative to connect a notebook computer
to the storage system, for initial configuration and
servicing the system.
A Dynamic Host Configuration Protocol (DHCP) server
is implemented over this port. The DHCP server
automatically assigns IP addresses to the notebook
computer and establishes a connection to the IBM
FlashSystem A9000R system.
Note: There is a second identical technician port on the
front of the rack, next to the power button. This
technician port connects to grid controller 2.
Maint (maintenance
module) ports Maintenance module (For technician use only.) These two ports connect
directly to the maintenance module.
Modem port Modem (For technician use only.) Use this port to connect a
modem for remote support.
Management port requirements
The management ports provide the connectivity required for IBM Hyper-Scale
Manager, IBM FlashSystem A9000R command-line interface (CLI), and other
management tools to monitor and control the IBM FlashSystem A9000R system.
IP configuration
The IBM FlashSystem A9000R storage system has three redundant management
port IP addresses, over Ethernet interfaces, in case of failure.
Each IP address is handled by different grid controllers in the initial grid element
configuration. It is recommended that the IBM Hyper-Scale Manager and CLI be
configured with all three IP addresses that are defined for IBM FlashSystem
A9000R for high availability. For more information about the IBM Hyper-Scale
Manager, see IBM Hyper-Scale Manager User Guide (SC27-8560) on the IBM
FlashSystem A9000R Knowledge Center website (ibm.com/support/
knowledgecenter/STJKN5)
Management functions can be performed through any of the IP addresses. These
addresses can be accessed simultaneously by multiple clients.
For each of the three management ports, the customer or technical assistant must
provide the following information to the IBM service representative before starting
the installation process:
v IP address of the port
v Net mask
