Reading Time: 2 minutesSome 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 minutesSome 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 minutesTo 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 storage part

16 November 2011
Comments off

Reading Time: 3 minutesThe 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 vSphere part

14 November 2011
Comments off

Reading Time: 4 minutesIn 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 […]

Upgrade path to vSphere 5

8 November 2011
Comments off

Reading Time: 3 minutesThe upgrade path to vSphere 5 is well described in the specific guide (vSphere Upgrade Guide) and in the vSphere Upgrade Best Practices white paper.. In some cases an in-place upgrade can be applied with the advantage to require less time and to keep all (or most) of the settings and configurations. For example, a vCenter Server 4.1 can be updated to the 5.0 version (the requirements of the two versions are quite the same) or an old ESXi can be updated to ESXi 5. But in most cases, also when the in-place upgrade is […]

Reading Time: 2 minutesSource: VMware vSphere 4.1 Update 2 Released The VMware vCenter Server 4.1 Update 2 release offers the following improvements: Support for new processors: vCenter Server 4.1 Update 2 supports hosts with processors on AMD Opteron 6200 series (Interlagos) and AMD Opteron 4200 series (Valencia). Note: For the AMD Opteron 6200 and 4200 series (Family 15h) processors, vCenter Server 4.1 Update 2 treats each core within a compute unit as an independent core, except while applying licenses. For the purpose of licensing, vCenter Server treats each compute unit as a core. For example, although a processor […]
