While looking at OpenStack as the control plane for vSphere it appears there isn’t too much detail and I found it tricky to create my first OpenStack image. Here are the steps I followed.

When designing data ONTAP and the WAFL file system they were the first to look at creating a virtual control plane for data. They also pioneered fully non disruptive upgrades when the introduced clustered data ONTAP. They then introduced ONTAP Edge for providing the really cool features of data ONTAP for non NetApp SANs.

Most file names were not changed when 64-bit versions of the DLLs were created, so 32-bit versions are stored in a different directory. WOW64 hides this difference by using a file system redirector. As such whenever a 32-bit application attempts to access %windir%\System32, the access is redirected to %windir%\SysWOW64.
