Virtual Connect Stacking questions regarding module requirements

[chuckk281]

Gaston had a MUlti-Enclosure Stacking (MES) question:

*************

Hello Team, I have a Customer who is planning to cascade 2 C7000 Enclosures. One they have and buy a new one.

In the old Enclosure they have VC Flex-10 Modules in Bay 1 and 2. On the new Enclosure they’re interested in buying the new version Flex-10/10D and configure them in the same Bays. Is cascading supported in this scenario?.

In this document I’ve found that it’s not recommended: http://h20566.www2.hp.com/portal/site/hpsc/template.BINARYPORTLET/public/kb/docDisplay/resource.process/?spf_p.tpst=kbDocDisplay_ws_BI&spf_p.rid_kbDocDisplay=docDisplayResURL&javax.portlet.begCacheTok=com.vignette.cachetoken&spf_p.rst_kbDocDisplay=wsrp-resourceState%3DdocId%253Demr_na-c03801914-2%257CdocLocale%253Den_US&javax.portlet.endCacheTok=com.vignette.cachetoken, in page 16 it says: “All enclosures must have the same HP VC Flex-10/10D module configuration. For example, if bays 1 and 2 of the Primary Enclosure contain HP VC Flex-10/10D modules, then bays 1 and 2 of Remote Enclosures 1, 2, and 3 must also contain HP VC Flex-10/10D modules.”

Do you have another point of view?

The document is correct. The enclosures in a multi-enclosure domain must all have the same module configuration.

Just FYI, the reasoning is that the 10D module, just like FlexFabric, supports FCoE Uplinks.

Anything with FC/FCoE uplinks must be configured identically across all enclosures in a domain.

This rule has been around forever I think in VC.

Suggestions?
