ESXi – Use the embedded VNC Server

12 December 2011
Comments off

Reading Time: 3 minutes Some weeks ago I learn a new curios thing in a thread in the VMware Community: also the latest version of ESXi still have a VNC Server for the VM console that can be used with a common VNC connection as described in the old KB1246 (Using a VNC Client to Connect to Virtual Machines) related to the VMware GSX Server product! Note: as written in the KB VMware does not support running virtual machines with a VNC client. The right client to access the VM console is still the vSphere Client (or the Web […]

ESXi Performance Graphs – VM Power

9 December 2011
Comments off

Reading Time: 2 minutes There is an performance monitor at VM level that show always a null value: it’s the VM Power Graph. The same monitor at host level show the power usage of the specific host. But by default, the power usage of the VMs are not calculated. To enable this experimental feature you must change an advanced parameter (Power.ChargeVMs) on each host (by default, as show in the picture, is zero… it must be changed to 1):

ESXi – RDM disks with SAS Storage (local or shared)

29 November 2011
Comments off

Reading Time: 2 minutes The RDM disks are a feature of VMware vSphere (but was present also in Virtual Infrastructure) to make a “mapping” between a LUN (or logical disk) to a VM (is similar to a disk pass-through). This feature can be used in different cases, for example: to support disk larger than 2 TB (only in vSphere 5 with physical RDM) and to implement guest clustering with shared storage (still only with physical RDM). But there is an issue (or a feature :) ) that does not allow to add a RDM disk from the GUI for […]

Upgrading to ESXi 5 vs. doing a Fresh Install

23 November 2011
Comments off

Reading Time: 3 minutes In a vSphere upgrade process, there are two different approach for the host upgrade: a fresh re-install or a in-line upgrade. In the VMware site there is an interesting post about this choice. The differences between an upgraded host and a freshly installed host are:

Hyper-V 3.0 vs. vSphere 5.0

20 November 2011
Comments off

Reading Time: 2 minutes Some days ago, VKernel has release a post (Hyper-V 3.0: Closing the Gap With vSphere 5) that compare the new Hyper-V 3.0 with the existing vSphere 5.0. I don’t know if the post was written before of after the Quest acquisition, but it doesn’t matter: it’s a comparison of two products not homogeneous, because will be released probably next year and and one was released on August of this year. But the data can still be used to see how Microsoft is working to reduce and close the gap with VMware, at least on the […]

Upgrade path to vSphere 5 – Conclusions

18 November 2011
Comments off

Reading Time: 2 minutes To close the series of post on the vSphere upgrade path to version 5 I will make a few final considerations: As written several time, check the hardware and software HCL before start the migration. The HCL may change from the beta release (where, for example, there was’t any SQL Express 2005 support) but also from one week to another (for example, some weeks the Dell PoverVault MD3x00/MD3x00i were not yet included). Actually most additional software are already compliant with vSphere, or with new version (like View 5) or with simple patch. Remember that vSphere […]

Upgrade path to vSphere 5 – The vSphere part

14 November 2011
Comments off

Reading Time: 4 minutes In a vSphere 5 upgrade path, the vSphere part of the upgrade process is the simples part and the order is the same of previous upgrade: first the vCenter Server (that can handle new and old hosts), then VUM (if you want to use it to upgrade the hosts), then the hosts, then the VMware Tools of the VMs and finally, if needed the VMFS5 of the datastores and the virtual hardware of the VMs. vCenter Server The upgrade of the vCenter Server is really simple and if you start from a version 4.1 you […]
