yes. There are at least some implementations of iSCSI and the accompanying management services (e.g., for redundancy) that do not work well via routed connections. Generally, storage services may be difficult being routed. Further, some aspects of VMware (clusters) including management "need" L2 connectivity, for example when you want to dynamically shift VMs from one hardware node to another transparently and so on and so forth. The same applies to several load balancing and/or redundancy/failover mechanisms. rgds, .m
