I did some Googling about SAN chunk size and VMFS 5 and found precious little information. In choosing a chunk size for VMFS 5, should the block size, or the sub-block be the primary consideration? I...

There's no standardized meaning for the term. Your 1st, 2nd and 3rd definitions have all been used by various vendors.

are there any negative impacts then to having different multipathing policies in use on different LUNs used by the same HA / DRS cluster?
View ArticleRe: Setting MultiPathing Policies on a per-LUN basis
No, not that I would know of. Basically the best option - if supported by the storage - is Round-Robin for most use cases, except e.g. MSCS as in your case. André

Hi, You need to change the SCSI controller option in each VM, the right option is "physical" for the bus sharing. You need to change this with the VMs power off. Hope this be useful for you Regards
