A company runs a data center for smaller customers. Someof their customers require
24x7availability. The company infrastructure consists of traditional 1Gb Ethernet and 4Gb
Fibre Channel networks. Their SAN consists of a dual redundant fabric with six HP
StorageWorks 4/32 SAN Switches in each fabric. The fabrics have a full-meshed topology
with two ISls for each mesh link. They have only two available freeports on each switch.
They have 20 VMware-based servers and 7 Windows 2008 servers, which are attached with
redundantpaths to their SAN. They also have three HP EVA 6xxx and two tape libraries with
4 drives of HP Ultrium 4 FC drives in eachtape library. Recently they added two HP 3PAR
StoreServ 10400 Storage Systems. The servers and storage devices are distributed on the
switches. All of the devices are distributed between two data centers that are 1 km apart.
The company has not experienced any performance issues. They plan to acquire additional
customers and are concerned that their infrastructure will not support future growth. The
company wants to make sure that they will be able to accommodate changing I/O traffic
patterns and reduce the complexity for expansion. Which change to the SAN should you
recommend in your presentation to the IT Director of the company?

A.
change to HP SN6000 Stackable Fibre Channel Switches

B.
change to core-edge-topology for each fabric

C.
add the HP B-series SAN Network Advisor Enterprise to each fabric
