Hi

In EVA sysem Can I Present one Virtual Disk to many Windows servers?

I means only one server can access and read/write. another server need to read only.

Is this possible?

No, not without a real cluster filesystem.

Right.

1. all presentations are either read/write or read/only.

2. As far as I can tell, Windows cannot mount NTFS readonly - at least it hung during boot when I tried it.

3. mounting a disk read-only prevents active file system corruptions, but the readers are not made aware by the writer which part of the file system changes. That is why you need a true shared file system implementation.

Or, present your disk to one server, and use windows share to present it to others.

You can also look into 3rd party products, such as Polyserve.
