Plan network connections
With your network administrator, determine the IP addresses and network
parameters you plan to use with the storage system. You must have this information
to set up and initialize the system.
You manage the storage system through a dedicated LAN port on each storage
processor. These two ports must share a subnet with the host you use to initialize the
system. After initialization, any host on the same network and with a supported
browser can manage the system through the management ports.
If you plan to connect your storage system to an iSCSI network, you will need to
configure servers and target storage systems in IP networks that use the iSCSI
protocol. EMC supports a variety of configurations, but recommends discrete
networks that are dedicated to iSCSI data traffic.
Each storage processor has four iSCSI ports for connecting the storage system –
either directly or through a network – to network interface cards (NICs) or iSCSI host
bus adapters (HBAs) in a server. The iSCSI data ports on the SPs are often called
targets; ports on NICs and iSCSI HBAs are iSCSI initiators.
In a server with multiple NICs or iSCSI HBAs that are connected directly to the storage
system, or that are on a dedicated iSCSI network, the initiator ports must be on separate subnets.
Record network information for your system on the worksheet on the next page.
Your network administrator should provide most of this information; for more
information, refer to your configuration planning guide.
For your convenience, the worksheet includes fields for username, password, and
storage-system serial number. You can determine and assign these values later.
