I am familiar with the LSI Logic storage and it will depend on two things. 1) What model of RAID controlelrs are you using and 2) How are you wanting to use the storage. LSI did make a system, referred to as the ISH (Intelligent Storage Hub) that was designed to be connected, as a node, anywhere on a LAN. The more traditional storage (disk arrays) are designed to be used with hubs or switches as they posses the ability to support SANs.
Do you have more information on the system that you are running?
