Metro Cluster with two shelves

[alexey_tkachev]

Hi all!

My customer wants to build an asymmetric active-passive MetroCluster with two shelves total only (one shelf on first side and another shelf on second).

See picture.

And we have a questions:

• Is it possible to implement (technically)?
• Is it a supported configuration?

Regards

Alexey

It is possible technically with controllers that support software based disk ownership in Metro Cluster (not supported for older models); best practice is to dedicate the whole shelf to head though.

I let someone from NetApp to comment on supportability of such configuration ☺

This doc is worth reading:

It does refer to software disk ownership, albeit it doesn't explicitly either disapproves or approves the config in question.

Regards,

Radek
