External Connection on VxRail
a Hi all
I have user case where we have Management Pod which host Viper SRM ESRS, Log insite, VCentre etc.
As this going to be quite small environment but is operatailal important
The ask is to connect external Array such as VNX, to a VxRail my understanding is that this can be done via iSCSI
The account is SMS account and the intent is to connect external storage to Vxrail appliance via TOR switch's.
I understand there could be performance issue and FTT would have to be factored in
I have few question
1. Can I connect to Vmax?VnX using iSCSi
2. Any have architecture that I could use or any guidance that could be provide

Yep! You can use externally mounted datastores within VMware via iSCSI or NFS for connectivity Please note that those NFS/iSCSI datastores will need to be managed through the vSphere WebClient and not through VxRail Manager. Also, if VMs need to be created with storage from those external devices, you'll need to create them through the WebClient. This should be treated as a "standard" vSphere cluster with NFS/iSCSI mounted datastores. The VSAN datastore is not extended to external devices.

Its working fine, but you need change default mtu.

Yes, it works the best.
I have multiple environments running VxRails connected to Unity storage arrays connected through dedicated Ethernet switches for Storage connectivity. We have dedicated 2x 25Gbps NIC in the VxRail nodes connected through 2x separate switches to establish 2x separate storage paths between the Initiator and Target.
In the ESXi end, we use standard vSwitch for each path and have a dedicated VLAN in each of them through a VMkernel adapter.
The external iSCSI storage is used as a second primary storage capacity that balances with VSAN capacity. Any availability problem shall still helps to keep the 50% application landscape up and operational.
