We have an OEM storage vendor telling us that it is NOT recommended at this time to use SAS interposers with any SATA drives (regardless of brand or type (HDD or SSD)) and use it with Windows Storage Spaces/Clustered Storage Spaces. This would be for a shared-SAS backend using a JBOD/HBA and Windows Storage Spaces as a scale-out file server solution. This is the setup you see referenced from Microsoft all over the place.
Is anyone seeing any issues? They claim it's an issue with the LSI SAS interposers (LSISS9252) that all storage vendors rebrand or sell. And, apparently LSI is not seeing this as a high priority fix.
They're alleging that Microsoft product development has told them it's an issue with the firmware on the SAS interposers (which is only upgradable by OEMs BTW) and that using these will result in drives dropping off/not showing up.
BTW, this comes from a Windows Storage Spaces certified product...thoughts? I'm just looking for any information so we can make an informed decision.
