HP Virtual Connect: Common Myths, Misperceptions, and Objections, Second Edition

Cisco 3120

#25: VC requires a separate web management window to manage

each VC module

). The use of the IEEE standard version, LLDP, is recommended by HP to ensure

customers are not locked into a proprietary protocol.

Incorrect: A single Web management window or CLI prompt is used to manage all VC modules in

the same VC Domain. If using Virtual Connect Enterprise Manager (VCEM), a single VCEM User

Interface can be used to manage server profile management (creation, deletion, movement, etc.)

across up to 100 VC Domains.

#26: VC doesn’t support IGMP Snooping

Incorrect: VC supports IGMP snooping for IGMP versions 1 and 2.

#27: VC Fibre Channel doesn’t support nested NPIV

Incorrect: This feature is provided in VC version 1.31 and above. Below is a table outlining the

supported maximums and what minimum firmware version required.

#28: Virtualized MAC and WWN (NAT) features on some switches (for

example, Cisco’s FlexAttach

Incorrect: One of the many features provided by Virtual Connect is the ability to “manage” the

server blade MAC addresses. Specifically, Virtual Connect ‘manages’ the server blade MAC &

WWN addresses. Virtual Connect does not “virtualize” the server blade addresses. Many VC

administrators don’t appreciate the difference between ‘virtualized’ addresses and ‘managed’

addresses.

feature) provide the same benefits as VC’s

Managed MAC addresses and WWNs
