2 Using StoreVirtual Multipathing for Windows
The StoreVirtual DSM for Microsoft Windows MPIO is commonly referred to as the StoreVirtual
DSM. This DSM provides advanced multipathing capability for StoreVirtual cluster deployments in
Windows Server environments.
Best practices
•
If the StoreVirtual DSM is not required, then do not install the StoreVirtual DSM or enable the
Microsoft DSM service.
•
If you are currently using the StoreVirtual DSM, then upgrade to the latest version.
•
To avoid issues with active/passive StoreVirtual DSM configurations and disk timeout errors
when the iSCSI initiator detects a failure and reconnects, change the EnableNOPOut registry
setting to 1 as described in the Microsoft iSCSI Initiator Driver Timers section of the Microsoft
iSCSI Software Initiator Version 2.X Users Guide.
•
The StoreVirtual DSM is recommended for the following:
◦
Providing the maximum possible performance for specified configurations.
◦
With Multi-Site SAN storage clusters, the StoreVirtual DSM with site preference is
recommended, particularly if the intersite link is significantly slower than local access.
This configuration will ensure that reads are performed with a local replica when one is
available. This is particularly useful for Microsoft clusters where a Microsoft cluster node
is on each side of the intersite link.
•
The Microsoft DSM is recommended for the following configurations:
◦
For any volumes that are accessed by ESX and Windows initiators (as might be done for
VMware Consolidated backup), do not use the StoreVirtual DSM.
◦
Configurations requiring connections through storage routers.
◦
Large Hyper-V clusters (either large storage clusters or many server NICs).
◦
Large storage clusters with simultaneous access to many volumes using the StoreVirtual
DSM may encounter the Microsoft limit of 255 iSCSI sessions. In this case, use Microsoft
MPIO, which uses fewer sessions. To determine whether the Microsoft MPIO iSCSI session
limit might apply, multiply the expected number of volumes by the number of storage
systems plus the number of server NICs. If you are using Round Robin load balancing,
add an additional session per server NIC per storage system per volume. Active/passive
or vendor-specific load balancing settings use an additional session per storage system
per volume.
◦
Running the DSM on a Windows virtual machine that has VMware ESX Server or VMware
Hyper-V Server installed.
NOTE:
If the storage configuration is not recommended for the StoreVirtual DSM, then uninstall
the StoreVirtual DSM during the upgrade to Version 9.x or later, and use the Microsoft DSM.
Using Microsoft DSM
Beginning with LeftHand OS software Version 9.0, you can use the Microsoft DSM on your
application servers. For additional information about the Microsoft DSM, see the DSM white paper
available from the Microsoft website:
