SAN Network
SAN access requirements include:
•
NAS service management IP address
– IP address for PS Series group access to the NAS service. Must
be on the same subnet as the group IP address.
•
NAS node IP addresses for SAN access
– IP addresses for PS Series group access to the NAS nodes.
Specify one (minimum) or four (recommended) IP addresses for each NAS node. When creating a NAS
service, in the dialog box that prompts you for the SAN access information, click the
Auto fill
button to
automatically enter one or four IP addresses for each NAS node, based on the NAS service management IP
address.
Note:
Dell strongly recommends that you specify
either
one or four IP addresses for each NAS node;
do not
specify two or three IP addresses for each NAS node.
Internal Network
Internal network requirements include:
•
Block of IP addresses
•
Initial IP address for the address block
When you configure or modify the internal network configuration, you 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 IP
address (0 for the fourth octet).
•
128 IP addresses (/25) - Specifies 128 for the IP address block size. Allows two choices for the initial IP
address (0 or 64 for the fourth octet).
•
64 IP addresses (/26) - Specifies 64 for the IP address block size. Allows four choices for the initial IP
address (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 some
cases (for example, in a Class C network), selecting the option for 256 IP addresses is the easiest and provides
the most flexibility. However, if you do not want to allocate such a large number of IP addresses, you can select
a different option.
The actual size of the IP address block does not have any impact on NAS service performance.
