Re: Two nodes HA GUI vs Powershell

Hi, I have encountered this nasty issue - its easily fixed once you know where the problem is. The key is to specify the same device id for both nodes, this has to be forced explicitly: eg. $firstNode.SerialID = "050176c0b535403ba3ce02102e33eac" $secondNode.SerialID = "050176c0b535403...

Re: Performace one big vs several small

Hi, 1] Deduplication is not ideal for virtualization - you should avoid it when deploying virtual machines 2] SSD cache is nearly useless for data storage - I would dedicate it all for virtualization device 3] RAM disk is extremely important if working with RAID6, dedicate most for VM storage - but ...

Re: how does starwind maintain data integrity?

If you have only 1 node then its more difficult. Plase share your configuration. About the nested FS, I think it only matters on the StarWind node itself, the StarWind device FS does not matter, and in fact, nested ReFS might be bad for performance (this might not be true - depends on StarWind imple...

Re: how does starwind maintain data integrity?

Hi, I ve had similar very question: https://forums.starwindsoftware.com/viewtopic.php?f=5&t=4938 It would seem StarWind does not handle this at all - as it is mostly non-existent issue (10-14 is too conservative of an estimate as numerous sources say). Prevention of this issue should be done by ...

Re: 3-Node HA iSCSI - Virtual SAN "Scrubbing"

Thank you very much for the reply. Just to completely clarify: *On URE another node will serve eventually it - this is happening on StarWind fabric level or client level? There will no notice of this error on the connected client except perhaps a longer delay? *The resync process will begin automati...

Re: 3-Node HA iSCSI - Virtual SAN "Scrubbing"

I have done some more research to this topic and found that detection of this kind of errors can be done and managed somehow, but more questions arose: Can StarWind deal with unrecoverable disk error on read? How? Does another node serve the request? Can the data be corrected using information from ...

3-Node HA iSCSI - Virtual SAN "Scrubbing"

Hello, I want to know if theres a possibility to do something similar to RAID scrubbing on the HA device that has 3+ nodes (3 nodes needed for so called "scrubbing quorum"). I plan to deploy low cost 3 node setup with multiple HA devices - basically distributed triple mirror so to say. Doe...
