The 14 Fibre Channel
p
orts on the McDATA 4314 include 10 internal
p
orts for connection to the 10 server blades in the Dell Modular
Server Enclosure and
f
our external
p
orts
f
or connectivit
y
to the SAN
infrastructure. Because each of the 10 internal ports connects directly
to a server blade via the enclosure’s
p
assive mid

lane, administra-
tors cannot

One key feature of the

is the HotCAT feature, which
provides the mechanism to
