v Default gateway IP
v
Maximum transmission unit (MTU)
Notes:
v
All management IP interfaces must be connected to the same subnet and use the
same network mask, gateway, and MTU.
v MTU configuration is required if the network supports an MTU that is greater
than the default 1536 bytes. The largest possible MTU supported is 9216 bytes.
In addition, the customer or technical assistant must provide the following
system-level IP information:
Note: IPV6 is supported.
v IP address of the primary and secondary DNS servers
v IP addresses or DNS names of the SMTP servers
v IP addresses or DNS names of the NTP server
v IP addresses and port numbers of the Remote Support servers
Protocols
IBM FlashSystem A9000R is managed through dedicated management ports that
are running TCP/IP over an Ethernet connection.
All traffic over these ports are encrypted through the Secure Sockets Layer (SSL)
protocol.
Note: The management ports must be on a different subnet than the VPN ports
that are used for remote access.
Management is carried out through following protocols detailed in Table 23.

Command-line
interface (CLI)
(includes
Hyper-Scale
Manager) Proprietary 7778 Storage system management portal and CLI
act as the client and initiate the connection,
while IBM FlashSystem A9000R acts as the
server.
SNMP requests SNMP 161 Storage system responds to SNMP requests
when sending replies to SNMP managers.
SNMP
traps/notifications SNMP 162 Storage system initiates SNMP messages
when sending traps/notifications to SNMP
managers.
Outbound mail SMTP 25 Storage system initiates SMTP traffic when
sending emails for either event notifications
or for SMS gateways.
Time setting NTP 123 Storage system uses a network time
protocol (NTP) connection.
Connectivity IPSec 1293 Storage system uses IPSec for management
and VPN communication.
