Hi,
First time post and fairly new to the product.
Does anyone know why the block size option for data storage in the vSphere client defaults to 1MB in size? I see in tutorials and in blogs there were options in the formatting section for up to 8MB?
Thanks for your help.
Hi, Welcome to the Communities.
Here is some background on VMFS block sizes and their restrictions;
VMware KB: Block size limitations of a VMFS datastore
VMware KB: Frequently Asked Questions on VMware vSphere 5.x for VMFS-5
Remember, when upgrading from an earlier VMFS version, the block size is preserved. Newly provisioned VMFS-5 datastores have a unified 1MB block size.
Cheers,
Jon
For VMFS5, the only option now is 1MB block size. In VMFS3, the default block size is 1MB but you can change it to 1MB, 2MB, 4MB and 8MB

That's really kind. Thanks for the help (and the welcome) - much appreciated!
