Software Requirements for Microsoft Hyper-V - 3.5(x) Releases
The software requirements include verification that you are using compatible versions of Cisco HyperFlex Systems (HX) components and Microsoft Hyper-V (Hyper-V) components.
HyperFlex Software versions
The HX components—Cisco HX Data Platform Installer, Cisco HX Data Platform, and Cisco UCS firmware—are installed on different servers. Verify that each component on each server used with and within the HX Storage Cluster are compatible.

Important |
If your cluster is connected to a Fabric Interconnect 6400 series using VIC 1455/1457 with SFP-H25G-CU3M or SFP-H25G-CU5M cables, only use UCS Release 4.0(4k) and later, or 4.1(2a) and later. Do not use the any other UCS version listed in the table of qualified releases. Using a UCS Release that is not UCS Release 4.0(4k) and later, or 4.1(2a) and later may cause cluster outages. Refer to Release Notes for UCS Manager, Firmware/Drivers, and Blade BIOS for any UCS issues that affect your environment. For more information on the issue, see CSCvu25233 NOTE: If your current server firmware version is 4.0(4k) and later or 4.1(2a) and later, follow the upgrade procedure in the Cisco HyperFlex Systems Upgrade Guide for VMware ESXi, Release 3.5 Known Issues chapter. |
