perm-cache | Enables a permission cache. Specify this option if the server uses ACLs or if your server is configured to map client user IDs. This option enables the SteelHead to optimize traffic without violating the permissions model. |
policy {custom | global-rw} | Specifies one of the following policies: • custom - Enables you to turn on or off the root squash feature for NFS volumes from this server. • global-rw - Specifies a policy that provides a trade-off of performance for data consistency. All of the data can be accessed from any client, including LAN based NFS clients (which do not go through the SteelHeads) and clients using other file protocols like CIFS. This option severely restricts the optimizations that can be applied without introducing consistency problems. This is the default configuration. |
root-squash | Enables root squashing. Root-squashing allows an NFS server to map any incoming user ID 0 or guest ID 0 to another number that does not have super user privileges, often -2 (the nobody user). |
