Recently, we announced Windows Server 2022 preview, which introduces advanced multi-layer security, hybrid capabilities, and enhancements to modernize applications with containers. With feedback from customers, we are continuing to introduce new innovations for Windows Server workloads on Azure, on-premises, and at the edge. Off I go to travel the world and see cities where no PFE has gone before…Īs my lawyer would say… “This posting is provided "AS IS" with no warranties, and confers no rights.Customers trust Windows Server to run their business-critical and mission-critical workloads.

#TEAM OS WINDOWS SERVER 2012 SOFTWARE#
Hope you find this blog enlightening and clears up any doubts you might have heard regarding the ability to use NIC Teaming software with iSCSI. Windows Server 2012 NIC Teaming (LBFO) Deployment and Management documentation. Understanding MPIO Features and Components. When in doubt, you can always search the status of any hardware testing completed on the Windows Server Catalog - Certified for Windows Server 2012. In addition, we will always recommend you consult with your iSCSI storage vendor to confirm the support of iSCSI solutions with their storage. But when iSCSI is used with shared NICs, those shared NICs can be teamed and will be supported as long as it’s being used with Microsoft’s Windows Server 2012 NIC Teaming (LBFO) solution. When iSCSI is used with dedicated NICs, then using any teaming solution is not recommended and MPIO/DSM should be used. So even if the iSCSI initiators aren’t using Microsoft’s NIC Teaming (LBFO) solution (and perhaps not MPIO/DSM either), the iSCSI targets can use teamed NICs however you like. Just to make one point clear, the Microsoft’s Windows Server 2012 NIC Teaming (LBFO) solution is also supported for iSCSI targets (such as Microsoft’s iSCSI target) anytime, not just in the shared NIC scenario.In a native environment where the NICs are shared between iSCSI Initiator and other uses, the following configuration is also supported.If iSCSI Initiator is used in a shared NIC scenario (see figure below) such as in a Hyper-V 2012 environment, then iSCSI Initiator used over the Hyper-V switch (and over NIC Teaming) is supported.If iSCSI Initiator is used with dedicated NICs such as in a stand-alone and/or Failover Clustering environment, then NIC Teaming should not be used (because it adds no benefit over MPIO for dedicated NICs).The Technet statement that basically quotes “ iSCSI + NIC Teaming not supported” is still true for all teaming solutions, with the EXCEPTION of the Windows Server 2012 inbox NIC Teaming solution we provide.Program Manager / Windows Core Networking) who is the authority on this subject and here is the essence of the message he conveyed: So to demystify the question that inspired to write this blog, I consulted with Don Stanwyck ( Sr. You can consider using MPIO software instead.” Is NIC Teaming supported for iSCSI, or not supported for iSCSI?īecause when customers read this TechNet article Failover Clustering Hardware Requirements and Storage Options, it states “ For iSCSI, network adapter teaming (also called load balancing and failover, or LBFO) is not supported. So here’s where the confusion comes in and a lot of customers have been asking us… Now with the release of Windows Server 2012, we include our own version of NIC teaming software also known as Load Balancing/Failover ( LBFO). Even then in those days, neither the vendors nor Microsoft supported teaming iSCSI Initiator and recommended using the vendor’s MPIO (multi-path I/O) solution and/or DSM (device-specific modules). Well in previous releases of the operating system, customers always depended on vendors to provide a support solution for NIC Teaming software.
