ShadowStream System Requirements
Supported Operating Systems for the ShadowStream service and administrator console:
- Windows Server 2003
- Windows Server 2008
- Windows Server 2008 R2
- Windows Server 2012
- Windows Server 2012 R2
|Note: ShadowStream can be installed on a 64-bit or 32-bit version of Windows Server. However, StorageCraft recommends installing on a 64-bit operating system. On a 64-bit OS, the 64-bit version of ShadowStream will be installed. This allows access to more memory and a higher number of concurrent file transfers.|
Source and Destination Ports
Shadowstream replication communicates bi-directionally. This requires that the UDP ports are opened on both the source and destination networks for both the incoming and outgoing direction.
ShadowStream uses these UDP ports by default:
|4366||UDP data connection control port|
|4367||UDP Admin connection port|
Confirm access to these UDP ports through your firewalls to successfully run ShadowStream.
Maximum Transmission Unit (MTU) Size
The Maximum Transmission Unit (MTU) size needs to be a static setting. It also needs to be the same on both the source and destination network.
|Warning: Having different MTU sizes causes packet fragmentation in UDP packets and will cause replication to fail.|
StorageCraft has determined that the default MTU, in many cases is 1500. Some items require a specific MTU (for example PPOE requires an MTU of 1492). StorageCraft recommends analyzing your environment and evaluating what the specific settings for your network should be. This will help you properly select the right MTU.
Customers with Different MTU Size
If you have multiple customers who replicate to your system with different MTU sizes, you need to setup multiple receiving servers to match the MTU size for each specific customer.
