Does Unity support Windows Server 2025 ? Slow performance on iSCSI but at 2022 works no problem.
Hello., we have Unity 480F v5.1.0.0.5.394 connected to test host via 4x10Gb DAC Fiber via SPA, Raid10 on 15 Flash drives.
WS2022
WS2025
We check 2 DELL Servers and results are the same, a WS2025 seams not proper supported with iSCSI to Unity.
I not use PowerPath bcs this soft will be not longer sell, it need license and not it's not possible on testing get that soft and key.

Hi,
Thanks for your question.
It is on the support matrix. https://elabnavigator.dell.com/vault/pdf/EMC_Unity_ESSM.pdf maybe you need to be on a newer version than 5.1, 5.5 is the current version.
Let us know if you have any additional questions.

Unity is not on testing now but my distributor have it and do additional tests, update drivers of NIC and update firmware of Unity. From 0,7GB/s to ~2GB/s.
Result still weak opposite to WinSrv2012 :( who give us 3GB/s on write out-of-box with R10 on 15xFlash.
Any other suggestion ?

Hello Odyseja,
Is your version been upgraded to 5.5 instead of version 5.1? Also when it comes to performance issues in most cases we need to look at the whole environment to get a better understanding of what is causing the bottle neck. Which type switches is your Unity and your host connected to?
