RHEV 3.0 vs vSphere 5.0

21 November 2011
Comments off

Reading Time: 2 minutes Some days ago Red Hat has announced the availability of its Red Hat Enterprise Virtualization (RHEV) 3.0 public beta. The first beta of RHEV 3.0 was announced in August, but was not available to the general public. You needed to have an active RHEV subscription at that time. The evaluation is immediately available to anyone with a Red Hat Network account. About the new features and the improvements there is a specific page on RedHat site. Red Hat Enterprise Virtualization 3.0 includes updates such as: Red Hat Enterprise Virtualization Manager is now a Java application […]

Hyper-V 3.0 vs. vSphere 5.0

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 backup part

17 November 2011
Comments off

Reading Time: 3 minutes When the vSphere infrastructure is upgraded, than also the backup part needs a check (and maybe a refresh). But, in order to avoid big issue, is better check it also before the entire upgrade, just to be sure that all remain supported. I also suggest to use this as a potential review of the the entire backup policies to find how to improve them and/or how to use different solutions (not necessary different products). About the backup programs, most of them could still work with vSphere, because the vStorage APIs for Data Protection (VADP) are […]

Upgrade path to vSphere 5 – The storage part

16 November 2011
Comments off

Reading Time: 3 minutes The storage part of a vSphere 5 upgrade path has two different steps: a firmware upgrade, that may be needed before start the vSphere upgrade (see the hardware part) and a modules/plugins/utilities upgrade, that is applied after the vSphere upgrade. In my case, for an EqualLogic array, the minimum firmware version compatible with ESXi 5 is the 4.3 release (but I’ve tried also with a firmware 4.0.6 and it works), but you will need at least the 5.0 series in order to support VAAI and VASA (see vStorage API). New firmware works also with vSphere […]

Upgrade path to vSphere 5 – The VM part

15 November 2011
Comments off

Reading Time: 2 minutes As written in the previous post, the VM upgrade (after a vSphere upgrade) require first the upgrade of the VMware Tools and then (if needed) the upgrade of virtual hardware. But there are also more considerations to do. Some days ago, I was involved in a upgrade path a little unusual: from VI 3.5 (and also quite old, only U2) to vSphere 5. For hosts and vCenter Server was simple: just a re-installation and re-configuration. But there where more issues  in the VMs upgrade. Here some of my considerations: Seems obvious, but a VM check […]

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 […]
