The Distributed LAN (Disk Proxy) Networks

 

The SNFS External API might be useful in some scenarios because it

SNFS External API

offers programmatic use of special SNFS performance capabilities such as

 

 

affinities, preallocation, and quality of service. For more information, see

 

the Quality of Service chapter of the StorNext User’s Guide API Guide.

The Distributed LAN (Disk Proxy) Networks

 

As with any client/server protocol, SNFS Distributed LAN performance

 

is subject to the limitations of the underlying network. Therefore, it is

 

strongly recommended that you use Gigabit (1000BaseT) for Distributed

 

LAN traffic. Neither TCP offload nor jumbo frames are required.

 

SNFS Distributed LAN can easily fill several Gigabit Ethernets with data,

so take special care when selecting and configuring the switches used to

 

 

interconnect SNFS Distributed LAN clients and servers. Ensure that your

 

network switches have enough internal bandwidth to handle all of the

 

anticipated traffic between all Distributed LAN clients and servers

 

connected to them.

 

A network switch that is dropping packets will cause TCP

 

retransmissions. This can be easily observed on both Linux and Windows

 

platforms by using the netstat -scommand while Distributed LAN is in

 

progress. Reducing the TCP window size used by Distributed LAN might

 

also help with an oversubscribed network switch. The Windows client

 

Distributed LAN tab and the Linux dpserver file contain the tuning

 

parameter for the TCP window size. Note that Distributed LAN server

 

remounts are required after changing this parameter.

 

It is best practice to have all SNFS Distributed LAN clients and servers

 

directly attached to the same network switch. A router between a

 

Distributed LAN client and server could be easily overwhelmed by the

 

data rates required.

 

It is critical to ensure that speed/duplex settings are correct, as this will

 

severely impact performance. Most of the time auto-detectis the correct

 

setting. Some managed switches allow setting speed/duplex, such as

 

1000Mb/full, which disables auto-detectand requires the host to be set

 

exactly the same. However, performance is severely impacted if the

 

settings do not match between switch and host. For example, if the switch
