SAN Connectivity Best Practices
This section provides general guidelines for physically connecting hosts with PowerStore cluster.
NOTE:
The diagrams throughout this section illustrate possible implementations of these guidelines. Other possible
implementations are not illustrated.
●
A PowerStore appliance contains two nodes.
●
To prevent a host path failure due to a single node failure, ensure that redundancy is maintained (connect each initiator at
minimum to each node).
Direct Attach
●
A host must be connected at minimum with one path to each node for redundancy.
●
See E-Lab for details of supported configuration with Direct Attach:
○
See the E-Lab Interoperability Navigator (
) for supported FC and iSCSI configurations.
○
See the E-Lab
Dell EMC 32G FC-NVMe Simple Support Matrix
for supported NVMe/FC configurations with Direct
Attach.
○
For a host that is directly attached to a PowerStore appliance, disable NVMe/FC support on the HBA. For details
on potential issues when directly connecting a host to PowerStore, see
Dell EMC Knowledge Article 000200588
(PowerStore: After an upgrade...)
and
Dell EMC Knowledge Article 000193380 (PowerStoreOS 2.0: ESXi hosts do not
detect...)
.
○
See the E-Lab
NVMe/TCP Host/Storage Interoperability Simple Support Matrix
for supported NVMe/TCP configurations
with Direct Attach.

NOTE:
Be sure to configure proper zoning for FC and NVMe/FC or proper subnetting with iSCSI and TVMe/TCP.

A host must be connected at minimum with one path to each node for redundancy.
