Amit, I completely understand your point of view, but at the end of the day the decision of upgrading or not, is completely up to you. As I stated before, vSphere 5.1i on B230-m2 blades is supported in UCS firmware 2.0 (4 a or b). However, I am attaching a link to the 2.0 release notes, which should hopefully help: Release Notes for Cisco UCS Software, Release 2.0 http://www.cisco.com/en/US/docs/unified_computing/ucs/release/notes/OL_25363.html#wp333546 As to exact step by step guide of upgrade, what firmware are you currently on? If you are upgrading between 2.0 releases: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/upgrading/from2.0/to2.0MR/b_UpgradingCiscoUCSFrom2.0To2.0MR.html If you are upgrading from 1.4 to 2.0 releases: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/upgrading/from1.4/to2.0/b_UpgradingCiscoUCSFrom1.4To2.0.html Also, these step by step video guides should help as well: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/video/upgrade/14to20/upgrade_20_a.html ...
