2 node hyperconverged hyper-v, with single NVMe PCie

[tekach]

Hello,

I am planning a migration to new servers and with that, their specification. Would StarWind VSAN Hyperconverged 2-Node Scenario with Hyper-V be ok with single high-performance NVMe PCIe SSD per node? So, without RAID1 or RAID10.

Performance and capacity wise, this is a no brainer (think Samsung PM1735), what about resilience / data safety?

One school of thought says - no, you really should not rely on a single drive ... but other says yes, it's a drive on a PCIe card and data is synced to other node anyway... Besides, RAID contoller is single point of failure just in the same way as such NVM PCie card is.

What is your view of this?

Any experience with Intel's VROC in case I go down the route of RAID1?

Would iSCSI pose any problems with such setup?

Best regards,
Andrej

Welcome to StarWind Forum. Please note that having no RAID (software or hardware) voids data redundancy within a node.
Going with a single drive that carries a StarWind device(s) mirrored to another server is what often users do and which is acceptable keeping in mind the statement above.
VROC might behave unpredictably when updating drivers, or under CPU loads; please note it to be a software RAID of some sort. Please check StarWind System requirements https://www.starwindsoftware.com/system-requirements.
