Free-Online-Exams.com A customer is refreshing server hardware within a data center and plans to upgrade the server edge switches at the same time. When an HP sales professional meets with the customer, the conversation turns to SAN/LAN convergence. The customer currently has SAN switches local to the data center. The old servers connected to these switches using Fiber Channel (FC) NICs (in addition to connecting to LAN switches over Ethernet). The customer definitely wants to eliminate FC NICs on the new servers. However, he is not convinced that the HP products Fiber Channel over Ethernet (FCoE) provides a better solution than Internet Fiber Channel Protocol (iFCP), which other vendors products support as well as the HP products. What are two points that the sales professional should make? (Select two.)
FCoE is easier to implement and adds much less overhead than iFCP.
FCoE supports performance similar to FC with read-write and read data hits taking less than 1 ms.
