- Can CUCM 8.5 (x) series be supported on VMware ESXi 4.1 U1 or 4.1 U2 ?
- In other words, can we upgrade ESXi from 4.1 to 4.1 U1 or 4.1 U2 on our UCS server (C210M2)
According to Cisco doc: CUCM 8.5(x) series is supported on VMware vSphere ESXi 4.0, 4.1, 5.0, 5.1 (but this doc doesn't talk about U1 & U2)
Solution: Yes it is supported & works fine
FYI:
:: ESXi Major/Minor Versions, Maintenance Versions and Patches/Updates ::
- Cisco Collaboration apps will explicitly indicate which Major/Minor versions they support (e.g. ESXi 4.0, 4.1, 5.0, 5.1, 5.5). There is no "or later" ... unlisted versions are not tested/supported.
- With a particular supported major/minor version (such as ESXi 5.1)...
- A Cisco Collaboration app will only specifiy a minimum maintenance release (e.g. 5.1 U1) if required by its guest OS or for hardware compatibility.
- A Cisco Collaboration app will only specify a MAXIMUM maintenance release if there are known incompatibilitites. To date this has never been the case, so if the hardware vendor supports it, it is allowed even if unlisted. Cisco recommendation is to use the latest Maintenance release supported by the hardware vendor.
- Cisco Collaboration apps do not prescribe or proscribe individual ESXi patches and updates. Cisco recommendation is to apply the latest patches and updates recommended by VMware and your hardware vendor.
