Recommendations & Troubleshooting

Recommendations

To reset the settings, install two jumpers on the board (located near the network connector) and turn on the device.

The existing configuration file will be erased.

 

Troubleshooting Guide

AcloudA Troubleshooting-1

The board operates with 1 stream; therefore, the speed is directly proportional to the latency.

We do not guarantee correct operation for channel widths to the server lower than 3 Mbit/s with delays greater than 65ms, as errors can occur when working with the file system and the ATA driver.

Some system administrators can partially or completely block certain packets including ICMP, UDP, TCP and ping.

Different file systems can have different timeout parameters for blocks.

Different implementations of iSCSI servers can have different boundary settings for response time and session creation.

The bandwidth of a channel can dynamically change due to the rebuilding of the routing tables of the network. You can check the route changes using the traceroute or MTR console utilities on Linux, and tracert on Windows.
