With Cisco Catalyst Intelligent Ethernet switches , Cisco helps companies realize the full benefits of adding intelligent services into their networks . Customers expect their investments to last much longer than ever before . This view is simplistic at best ; a single compromised host has the potential to disrupt other hosts attached to the SAN , access unauthorized data within the SAN , or bypass existing firewalls and intrusion detection systems if IP over Fibre Channel ( RFC 2625 ) is being used . Data management consists of a set of tools designed to ensure the availability of data within a system irregardless of the semantics of the data . The area of scalability should also address the migration of multiple services into the Data Center , which necessitates the tightening of security to secure hosts and applications from external ( and internal ) attacks . Connectivity to the storage is almost as important as the integrity of the storage itself . With Cisco Catalyst Intelligent Ethernet switches , Cisco Systems helps enable companies to realize the full benefits of adding intelligent services into their networks . Through CIR , bandwidth can be guaranteed in increments as small as 1 Mbps .
