in the 1979 and now employs over 900 people in the
worldwide. We evaluate some points of fibre channel
host bus adapter with other HBA's. We includes some
points like customer availability, model varity, operation
environment support, installation support, multi pathing
support, HBA management and support.


Evaluation summary
Our general finding that HBA product family is more
rich of features and wider breadth of support for server
hardware, operating syatem and path management.
Overall the installation process HBA is very much easier
for emulex. This management software is very much
efficient in the use if large environment. Current emulex
product family is mature, robust and well suited for
large to small fibre channel.


Customer Availability

restore. Firmware BIOS and
Fcode can be updated for one or
more adapters. There is no
reboots. No event log entries are
noted.


HBA performance graph
Vendor makes various
performance claims. A series

system through 4100 fibre
channel switch. Here we
include the MBPS graph.
