The closest to MetroCluster functionality you can get on your FAS2000 system, as I already mentioned is a scheme based on SnappMirror technology like SnapMirror SVM.
For example, you can upgrade your both systems to Cluster-Mode, add two 10GB cluster switches, combine them in a single cluster.
Or you can upgrade them but keep them separate.
Then configure DR SVM and mirror data periodically from your primary SVM to DR SVM.
In this configuration (unlike with MC) very important to have application consistent snapshots which you can get with SnapManager/SnapCenter or even with free SnapCreator software.
What protocols are you using?
Do you have additional licenses like SnapMirror, FlexClone, SnapManager in your system?
Is it still on support?
