Convert virtual disk format – VHD to VMDK

Reading Time: < 1 minuteAs you probably already know a VM is incapsulated with a set of files that define VM properties and objects. Some of those files are the virtual disks files and each vendor use its own format: VMware use the VMDK and Microsoft & Citrix use the VHD format. Note that there could be more sub-types (for example for the VMDK files, but we will explain in future posts). To convert between different format you can use some kind of converter to perform a virtual to virtual (V2V) task.

Comments off

Reading Time: 3 minutesIf you want to “play” with Windows 8 Consumer Preview or “Windows Server 8” Beta, then there are several installation options. Destinations Hard disk This the common solution, but mean the needs of a blank partition, or space to build a new partition, or the possibility to erase your disk. If you choose a dual boot configuration, of course, the bootloader must be modified to add the new entry. Physical installation permit to test most of the features and can give better performance (for example you cannot realize how fast is the boot procedure in […]

Virtualization ecosystem is becoming multi-hypervisor

6 February 2012
Comments off

Reading Time: 3 minutesOne trend in the last year(s) is that the virtualization ecosystem is growing outside the boundary where was born: historical partner vendor of VMware now are extending their solution to other hypervisors, and also also new products are designed to managed a more complex virtual environment. This was also called “Hypervisor Agnosticism” in a VKernel post. We do not talk about interoperability across different hypervisors, but simple use same tools, especially for management, monitoring and data protection, for more type of products. Does it make sense? For a single customer maybe not… have multiple environment […]

Reading Time: 3 minutesThe Dell EqualLogic team has officially announced the release of Host Integration Tools for Microsoft (HIT/Microsoft) v4.0, now available for download. The EqualLogic Host Integration Tools for Microsoft (HIT/Microsoft) tightly integrate the EqualLogic PS Series arrays with Microsoft host operating platform and host applications enabling consistent data protection (using snapshots and replicas), performance optimization (with a specific multipath module) and streamlined management and operation (for example to help to connect a host or to initialize an array). I’ve see HIT/Microsoft 4.0 during the last Dell Storage Forum and also during the beta period and it’s […]

Why Dynamic Disks are a bad choice

22 December 2011
Comments off

Reading Time: 3 minutesMicrosoft Windows Dynamic Disks (or Dynamic Volumes) are an abstraction layer (introduced in Windows 2000) over the partitions (similar to the LVM layer on Linux environment) to decoupled the volumes (with their NTFS data) from the disk partitions and have a greater flexibility, like hot-extend a volume by simple add new partitions (but also several other advantages). But in a virtual environment there are other way to handle disk flexibility, like hot-extend a virtual disk at hypervisor level (for VMware this feature was introduced in VI 3.5U2)… so there is no need to use dynamic […]

Hyper-V 3.0 vs. vSphere 5.0

20 November 2011
Comments off

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 […]
