Tip:  Optionally, you can also configure your network from the ProtecTIER Service menu  directly in the ProtecTIER server. Multiple ways exist to set up your networking to ensure that you have an HA configuration,  and that you distribute the load across all available resources. The default setup is a single  virtual interface,  fsi1 , which consists of all four physical 1 Gb ports (Table 5-1). Chapter 5. ProtecTIER File System Interface: General introduction  69
