Use of 4kn or 512e drives in iSCSI and FC storage

Jump to solution

Guys, could any one tell if it is possible to use storage with drives which block size is 4k, or 512e  in VMware thrue FC or iSCSI.

According http://kb.vmware.com/kb/2091600 Vmware is not supporting such disks in local storage.

Well in most cases it depends on controller which can or can not create volume/pool with block size 512.

I`am planning to use HPE MSA 2040 on K2Q82A drives (HP MSA 4TB 12G SAS 7.2K LFF (3.5in) 512e Midline 1yr Warranty Hard Drive)

For shared storage it's the HBA (in case of a physical HBA) and the storage system which needs to be supported.

The KB article actually contains the answer to your question.

This article applies to both HDD and SSD Direct attached drives. This does not apply to external storage arrays as long as LUNs presented to ESXi initiators use 512 logical sector size (READ_CAPACITY should report 512 logical block).
