We have a situation where we will have multiple customers hosted on a 9513 and sharing a single storage array.
We want to keep the logically seperated in their own VSANs, but of course the storage array will need to be zoned to all the customers hosts.
Now IVR should be the thing to use, but I'm getting resistance from the local team (screams of "Nooooo!!! They're EVILLLLL!!!") ... so I want to find out if there are some best practices around IVR use ?
Should they be used only for light duty stuff ? (though at present we use them with tape backup, which isn't exactly "light")
Do they impact performance to a measurable degree ?
Are they stable ?
What can go wrong with them ? And does it happen often ?
