In addition, each controller also has an actual, unique IP address. These addresses must be configuredmanually; you cannot use DHCP.SAN NetworkSAN access requirements include:• NAS cluster management IP address—IP address for PS Series group access to the NAS cluster. Must be onthe same subnet as the group IP address.• NAS controller IP addresses for SAN access—IP addresses for PS Series group access to the NAScontroller. Each controller has a real, unique IP address. These addresses must be configured manually; youcannot use DHCP. If you use DNS, you must make sure that the DNS database reflects the IP number bymanually setting the subsystem name and IP address.• Dell recommends four IP addresses for each NAS controller (use Table 9 to plan your initial networkconfiguration). When creating a NAS cluster, in the dialog box that prompts you for the SAN accessinformation, click the Auto fill button to automatically enter four IP addresses for each NAS controller,based on the NAS cluster management IP address.Internal NetworkInternal network requirements include:• Block of IP addresses• Initial IP address for the address blockYou can choose one of the following options:– 256 IP addresses (/24)—Specifies 256 for the IP address block size. Allows one choice for the initial IPaddress (0 for the fourth octet).– 128 IP addresses (/25)—Specifies 128 for the IP address block size. Allows two choices for the initial IPaddress (0 or 128 for the fourth octet).– 64 IP addresses (/26)—Specifies 64 for the IP address block size. Allows four choices for the initial IPaddress (0, 64, 128, or 192 for the fourth octet).The option you choose depends on your network configuration and the number of available IP addresses. In somecases (for example, in a Class C network), selecting the option for 256 IP addresses is the easiest and providesthe most flexibility. However, if you do not want to allocate such a large number of IP addresses, you can selecta different option.The actual size of the IP address block does not affect the NAS cluster performance.After obtaining the NAS cluster information, use it to complete Table 9. You will need this information whenconfiguring the NAS cluster.NAS Configuration Reference TableObtain the information described in Gathering the NAS Cluster Configuration Information on page 23 and fill inTable 9. Obtain IP addresses from your network administrator.25Dell EqualLogic FS7600 Installation and Setup Guide 5 NAS Cluster Configuration
