1. Re: IRST over 2TB disk support
Mar 14, 2018 11:45 AM (in response to RRadini)This message was posted on behalf of Intel CorporationHello RRadini,
Thank you for contacting us regarding our Intel® Rapid Storage Technology (Intel® RST), it will be more than a pleasure to assist you with this matter.
For this specific case scenario I regret to inform you that you are experiencing a limitation on both, hardware and software.
The Supermicro X8SAX motherboard (X58 chipset) supports Legacy modes, meaning that disks with 2 TB or more cannot be used for RAID volumes, due to a system limitation.
You can still use the disks, add and erase data from them, but this limitation on the RAID will be caused by the OS as well. The reason why is because Windows 7, has issues recognizing hard drives with more than 2 TB due to the fact that the disks need to be initialized in GPT and UEFI, which is not supported by the chipset that you own.
In this case RST can create the RAID volume on Legacy boot for less than 2 TB, however in order to go higher or beyond with the storage capacity, RST will need a UEFI mode motherboard and a newer operating system.
My apologies for the inconvenience that this may cause.
I hope this helps,
Best Regards.

2. Re: IRST over 2TB disk support
RRadini Mar 15, 2018 1:31 AM (in response to Intel Corporation)Hi Diego,
first of all thank you for your help.
AFAIK Windows 7 is able to recognize disk over 2TB(provided that it is initialized as GPT obviously), in fact I can use it as data disk (not OS), but I cannot use this disk as boot since X8SAX has no UEFI support.
Anyway what I would like is to have a 4TB RAID1 volume for data only (again, not for OS) based on two physical 4TB HardDrive initialized GPT, therefore this limitation should not matter in my case, may you confirm?

Thank you for your response.
In this case yes, I regret to inform you that due to the fact that the Supermicro X8SAX motherboard that you own has no UEFI support, our tool cannot communicate appropriately with the chipset, due to the limitation that it has, even if the RAID is not for OS but storage.
Best regards,
