4K Sector Format SAS/SATA Drives Considerations
• You must boot 4K sector format drives in UEFI mode, not legacy mode. See the procedures in this
• Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.
• Operating system support on 4K sector drives is as follows: Windows: Win2012 and Win2012R2; Linux:
