Access "iFCP vs. FCIP"
This article is part of the Vol. 4 No. 4 June 2005 issue of Exploring new options for disk-based backup
What switches support which protocol Brocade Communications Systems Inc.: Now supports FCIP, but had relied on Computer Network Technology (CNT) Corp. partnerships to provide distance solutions. Cisco Systems Inc.: Heavily invested in FCIP with a rich but proprietary feature set. CNT: Supports FCIP. McData may support both protocols after its acquisition of the firm. McData: iFCP after buying Nishan Systems. Growth is one of the most difficult challenges facing storage managers with Fibre Channel (FC) SANs because the FC protocol, by design, sacrificed scalability for speed. The Internet Protocol (IP) and the Ethernet network offer scalability that two variations of the FC protocol--iFCP and FCIP--use to connect SAN islands and overcome FC networking limitations. Unfortunately, each switch vendor supports only a proprietary version of iFCP or FCIP (see What switches support which protocol, this page). Storage managers need to understand the high-level differences between these two protocols to make better decisions on which protocol/switch best fits their ... Access >>>
