Control | Description |
Enable NFS Optimization | Enable this control on the client-side SteelHead to optimize NFS where NFS performance over the WAN is impacted by a high-latency environment. By default, this control is enabled. These controls are ignored on server-side SteelHeads. When you enable NFS optimization on a server-side SteelHead, RiOS uploads the NFS configuration information for a connection from the client-side SteelHead to the server-side SteelHead when it establishes the connection. |
NFS v2 and v4 Alarms | Enables an alarm when RiOS detects NFSv2 and NFSv4 traffic. When the alarm triggers, the SteelHead displays the Needs Attention health state. The alarm provides a link to this page and a button to reset the alarm. |
Default Server Policy | Select one of these server policies for NFS servers: • Custom - Specifies a custom policy for the NFS server. • Global Read-Write - Specifies a policy that provides data consistency rather than performance. All of the data can be accessed from any client, including LAN-based NFS clients (which don’t go through the SteelHeads) and clients using other file protocols such as CIFS. This option severely restricts the optimization that can be applied without introducing consistency problems. This is the default configuration. • Read-only - Specifies that the clients can read the data from the NFS server or volume but can’t make changes. The default server policy is used to configure any connection to a server that doesn’t have a policy. |
Default Volume Policy | Select one of these volume policies for NFS volumes: • Custom - Specifies a custom policy for the NFS volume. • Global Read-Write - Specifies a policy that provides data consistency rather than performance. All of the data can be accessed from any client, including LAN-based NFS clients (which don’t go through the SteelHeads) and clients using other file protocols such as CIFS. This option severely restricts the optimization that can be applied without introducing consistency problems. This is the default configuration. • Read-only - Specifies that the clients can read the data from the NFS server or volume but can’t make changes. The default volume policy is used to configure a volume that doesn’t have a policy. |
