StarWind Software

Hi,

We currently have the StarWind virtual SAN 2-node setup implemented using the following instructions:

https://www.starwindsoftware.com/techni ... luster.pdf

We are planning on replacing/upgrading the NICs in both machines. Would you please point me to, or provide, any documentation on the proper or safe way to go through this process?

Thank you!

Hello InphinitePhractals,
Basic steps are:
1. Open Failover Cluster Manager and move all storage from the second node to the first node.
2. Open StarWind Management console (if exists).
3. Check synchronization status of StarWind devices. In case, your StarWind Management Console is expired you need to run PS script GetHASyncState.ps1 and modify following strings for HAImage name and iqn. 4. If all devices are Synchronized, open the PowerShell as Admin and type "net stop starwindservice" on the second node.
5. Open Services and change startup mode of StarWind VSAN Service from automatic to disabled on the second node.
6. Turn off the second server and replace the NIC.
7. Power it back and specify the same IP for iSCSI and Sync channels.
8. Try to ping iSCSI and SYNC channels between the servers.
9. If communication works fine you can change the startup mode of StarWind VSAN Service from "disabled" to "automatic" and start StarWind service.
10. After above steps please confirm that the sync process completed and check that all targets in iSCSI initiator are connected.
11. Repeat the steps 1-10 for another node

Meanwhile, could you please specify the current NIC throughput (iSCSI and Sync) and throughput of new NIC?
Also, as far as I remember you have the commercial license of StarWind. Please feel free to contact StarWind support directly and our engineers will be more than happy to assist you with this operation.
Thank you.

Ivan-

Great to work with you again, and thank you for the instructions. I thought I'd post to the forum in this case and help expand the knowledge base.

As for throughput, these new NICs have 1GB channels, same as what's currently in there. The new model we got is: http://a.co/8jFE17v

Certainly, 10GB is preferred. Besides cost, we're trying to mimic our production environment as much as possible, which are currently 1GB as well.
