FAS9000 MetroCluster IP - Switch, SFP, & Cable Requirements

[JKW4]

Need Guidance Please...

I am hoping to transition an existing customer from a FAS9K Switchless Fabric MetroCluster to a MetroCluster IP Solution. 

• The existing MetroCluster HA Pairs are switchless(i.e. do not include Cluster Interconnect Switches).

• The new MetroCluster IP will have the following storage attached per side....

  • 2 x DS224C w/24x7.6TB SSDs
  • 1 x DS460C w/30x10TB 7.2K NL-SAS HDDs

I am trying to determine exactly what Parts/Pieces I need to configure to accomplish the transition.

To be quoted...

FAS9000 Internal

• Can HA Pair Cluster Interconnect remain switchless?
  • If not, what internal ports, NICS and SFP's must be included?
• Can I/Should I use the MetroCluster IP Switches as the HA Pair Cluster Interconnect?
  • If so, what SFP's and Cables must be included?

MetroCluster IP

• I believe that I need 4 x Cisco N9336C FTE 36 Port Switches - PN# X190210-FE-PE
• How many 100GbE ISL QSFPs do I need?  What PN#?
  • Cables? PN#

What am I missing? Not thinking of?

Thanks,

Joe W.

The MetroCluster documentation is extensive...

Intra-cluster (e4a/e8a) will go to the MC-IP switches (not switchless).

You'll need the X91146A NIC in Slot 5 for the remote HA/DR traffic.

You'll use this 9336C part number:
