VSM, vCenter, VSG, VNMC have to be at the same physical data center?

Hi, I listened to the Webinar "Long Distance vMotion with Nexus 1000V and Virtual Security Gateway" on July 27 2011.

https://communities.cisco.com/servlet/JiveServlet/downloadBody/25927-102-3-45387/Long%20Distance%20vMotion%20with%20Nexus%201000V%20and%20VSG.pdf

Page 48 says as follows.

The following components must be in the same physical data center:

Component

Version

Nexus 1000VVSMHA Pair,including VSM VM storage

  1. 4.2(1)SV1(4) or later

vCenterServerand vCenterServer Heartbeat pair

VMware vSphere4.1

VMwareUpdate Manager

VMwarevSphere4.1

Nexus 1010 HA Pair

  1. 4.2(1)SP1(3)

(Releaseavailability: August 2011)

Virtual Security Gateway

  1. 4.2(1)VSG1(1)

VirtualNetwork Management Center

VNMCrelease 1.0.1

IP Storage, if vmkis on N1KV

Depends on underlying storage technology

I have never seen this limitation on other documents.

Is this limitation old or still valid?

From my perspective, these components don't need to be in the same physical data center if they are reachable via IP.

Are there any reasons that they must be in the same physical data center?
