Multipathing I/O (MPIO) enables the use of multiple
iSCSI ports on a Drobo SAN to provide fault tolerance.
MPIO can also boost performance of an application by
load balancing traffic across multiple ports. This guide
describes how to easily configure MPIO to Drobo iSCSI
storage for a Windows server.
Topics
What you will need & Prerequisites
Provisioning Drobo storage volumes
Disabling Drobo Dashboard on cluster member hosts
Enabling Windows clustering and Hyper-V
Configuring the iSCSI initiator
Activating and formatting Drobo volumes
Configuring the Microsoft cluster
Provisioning Hyper-V virtual machines

  • Page 5 Drobo Dashboard typically handles all aspects of provisioning and mapping storage on Windows hosts. During installation it also modifies a number of registry settings to optimize iSCSI performance with the Drobo SAN. In a clustered environment, the Dashboard’s fault monitoring can interfere with disk migration between hosts. To provide the best performance while ensuring disk failover performs seamlessly, the Dashboard must be installed and then disabled on all cluster members.
