I have three questions about Windows clustering.
First question I have is a rather philosophical one:
Having some attached storage device, why would one even bother to use volume
shadowing at the operating system level? Most of us, when talking about
attached storage, think of SAN. There are far better possibilities to mirror
disks, both within and across controllers, while the operation would be more
efficient than shadowing at OS level. Shadowing at the operating system level
would make sense for internal disks, e.g. OpenVMS. In Windows this option is
not, however, available, which leads to the second question:
Why? Would quite interesting to have shadowing of internal disks.
Third question: Is it there a list of attached storage devices that can be
used for volume shadowing for Windows 2003 Enterprise?
Best regards,
Tudor Cristea
