Allocating IP Addresses
ARX Site Planning Guide 1 - 9
chosen server subnet must have enough address space for one proxy IP
address per network processor. The number of network processors varies for
each platform type. The following table shows the number of proxy IP
addresses for each platform type.
In any chassis type, the CLI issues a warning if insufficient proxy IP
addresses have been defined.
Adding Proxy IP Addresses to Domain Name Servers
During an NFS mount, some back-end servers perform domain name server
(DNS) reverse-lookups against remote NFS clients. This is designed as an
authentication mechanism. To prevent such file servers from denying access
to the proxy IP addresses, add the proxy IP addresses to your DNS
configuration.
Adding Virtual IP Addresses
Clients access ARX storage through a unique virtual IP address (VIP) or
VIPs. All VIPs can reside on a single client subnet or they can be divided
among several client subnets. Any client must be able to reach its respective
VIP. The ARX can send responses back to clients through a client subnet, a
static route, or a default route.
