PowerStore Operating System 2.x and Above - Multi Subnet About this task Use this procedure for configuring the iSCSI adapter on Windows hosts connected to PowerStore with a PowerStore operating system version 2 (or later) in which up to 32 network subnets are supported. For further details, see the Microsoft Windows documentation for the Windows version that is installed on the Windows hosts. Steps 1. Dell recommends creating four target iSCSI IP addresses (two per node), on two different subnets/VLANS. 2. Configure two iSCSI interfaces on the same subnet as the storage cluster iSCSI portals. Example: ● iSCSI-A-port0 1.1.1.1/24 ● iSCSI-A-port1 1.1.2.1/24 ● iSCSI-B-port0 1.1.1.2/24 ● iSCSI-B-port1 1.1.2.2/24 ● NIC0 1.1.1.10/24 ● NIC1 1.1.2.10/24 3. Proceed to configure Microsoft iSCSI adapter. Multipathing Software Configuration This topic introduces Multipathing Software Configuration for Microsoft Windows PowerStore supports native multipathing using Microsoft Native Microsoft Multipath I/O (MPIO) with Windows Server 2012/R2 and above, or multipathing using PowerPath. Configuring Native Multipathing Using Microsoft Multipath I/O (MPIO) This topic describes configuring native multipathing using Microsoft Multipath I/O (MPIO). For optimal operation with PowerStore storage, configure the Round-Robin (RR) policy or the Least Queue Depth policy for MPIO for devices presented from PowerStore. Using these policies, I/O operations are balanced across all available paths. To configure the native multipathing, using Microsoft Multipath I/O (MPIO), see: Enabling MPIO on the Windows Host and Configuring MPIO for PowerStore Volumes Presented to the Host Host Configuration for Microsoft Windows 51

PowerStore Operating System 2.x and Above - Multi Subnet
About this task
Use this procedure for configuring the iSCSI adapter on Windows hosts connected to PowerStore with a PowerStore operating
system version 2 (or later) in which up to 32 network subnets are supported. For further details, see the Microsoft Windows
documentation for the Windows version that is installed on the Windows hosts.
Steps
1.
Dell recommends creating four target iSCSI IP addresses (two per node), on two different subnets/VLANS.
2.
Configure two iSCSI interfaces on the same subnet as the storage cluster iSCSI portals.
Example:
●
iSCSI-A-port0 1.1.1.1/24
●
iSCSI-A-port1 1.1.2.1/24
●
iSCSI-B-port0 1.1.1.2/24
●
iSCSI-B-port1 1.1.2.2/24
●
NIC0 1.1.1.10/24
●
NIC1 1.1.2.10/24
3.
Proceed to configure Microsoft iSCSI adapter.

Configuring Native Multipathing Using Microsoft Multipath I/O
(MPIO)
This topic describes configuring native multipathing using Microsoft Multipath I/O (MPIO).
For optimal operation with PowerStore storage, configure the Round-Robin (RR) policy or the Least Queue Depth policy for
MPIO for devices presented from PowerStore. Using these policies, I/O operations are balanced across all available paths.
