## About LAN Names and IP Addresses

The following table shows the system's IP addresses and names, which are predefined and reserved.

| Name | IP Address
--- | --- | ---
Storage Service Processor | `sp` | `192.168.0.2`
Data Services Platform | `dsp00` | `192.1680.10`

The Storage Service Processor has a second IP address. See About Internal System IP Addresses for more information.

The IP address and LAN name for the Data Services Platform resides in the master management interface card (MIC). In the event of a failure, the alternate master MIC assumes the master MIC's IP address and continues its functions.

Each system has at least one array. Up to four arrays can be installed in the base cabinet, and up to six can be installed in an expansion cabinet. Arrays have fixed names and IP addresses based on their locations in the base cabinet and in any expansion cabinets. The following table lists the reserved IP addresses for all possible array configurations in all possible cabinets.

Description | Name | IP Address
--- | --- | ---
Lowest array (base cabinet #0) | `array00` | 192.168.0.40
Second array from the bottom (base cabinet #0) | `array01` | 192.168.0.41
Third array from the bottom (base cabinet #0) | `array02` | 192.168.0.42
Fourth array from the bottom (base cabinet #0) | `array03` | 192.168.0.43
Lowest array (expansion cabinet #1) | `array10` | 192.168.0.50
Second array from the bottom (expansion cabinet #1) | `array11` | 192.168.0.51
Third array from the bottom (expansion cabinet #1) | `array12` | 192.168.0.52
Fourth array from the bottom (expansion cabinet #1) | `array13` | 192.168.0.53
Fifth array from the bottom (expansion cabinet #1) | `array14` | 192.168.0.54
Sixth array from bottom the bottom (expansion cabinet #1) | `array15` | 192.168.0.55
Lowest array (expansion cabinet #2) | `array20` | 192.168.0.60
