VM /ETC

Archive for the ‘V2V’ Category

Because of the prevalence of virtual infrastructure these days, I’ll make the argument that virtual machine (VM) replication, both for business continuity (BC) and disaster recovery (DR) purposes, is the new P2V (physical to virtual migration) project. Not in the literal migration of physical to virtual, but in the same P2V concepts of infrastructure consolidation and capacity planning. I’m also talking similarity of process and in the frequency in which it is occurring. Simply put, IT shops that performed P2V migrations several years ago are now exploring how they can accomplish their DR site fail over or their BC needs with their virtual machines.

Let’s call these new generation of projects V4DR (virtualization for disaster recovery) or V4BC (virtualization for business continuity).

The comparison

If I rewind 3 to 5 years ago in my career, capacity planning for server consolidation was a weekly project and topic of discussion. Customers were either in the process of converting physical servers to virtual machines or they were exploring the possibility to do so. In both cases, capacity planning scenario spreadsheets and reports were frequent “ground zero documents” to almost every project plan I was involved in.

Just like P2V projects, VM replication today also requires some of the same considerations for job scalability and times to complete – i.e. using multiple hosts as targets and making sure the network can support getting the job done as quick as possible. Not to mention ip addressing, VLAN assignments, and application connectivity after the fact. Thank goodness we no longer have to deal with hardware drivers and other unneeded software a second time. Hopefully, VM alignment is a thing of the past too!

I’m not seeing the same “ground zero documents” for replication projects, however.

Use the same capacity planning tools?

So, I’ll ask the question:  Read the rest of this entry »

At the VMworld 2009 Vizioncore booth I discovered 3 new free tools from Vizioncore that all VI administrators, no matter which popular hypervisor platform you use, should know about. vConverter SC, vControl Multi-Hypervisor Management, and vOptimizer WasteFinder offer unique features that accomplish and automate common virtual environment administrative tasks. These products include tools for P2V and V2V migrations between multiple vendor platforms, a web based multi hypervisor management server, and virtual disk optimization through VMDK alignment and wasted storage scanning.

Vizioncore is banking on creating wider interest and adoption of its full product suite in the virtualization market, but for now administrators definitely come out the winners with these great tools at no cost. The free products mentioned in this post (as well as all of Vizioncore’s software) can be downloaded here.

I’ve summarized these utilities in the rest of this post. Read the rest of this entry »

A large percentage of VMware administrators have already used VMware Converter to conduct physical to virtual (p2v) migrations of their physical servers. For some reason though, VMware Converter always seems to be overlooked as a tool to accomplish virtual to virtual (v2v) conversions to an ESX target. Not only can you accomplish v2v migrations, but you can use VMware Converter to cross multiple vendor or incompatible virtualization host platforms.

For example, any of the following virtualization products running a Windows VM can be v2v -ed to an ESX host  with VMware Converter:

• ESX 2.x
• ESX 3.x / ESXi 3.x
• Virtual Server 1.x or 2.x
• Hyper-V
• XenServer
• any of the hosted desktop products including (but not limited to) VMware Workstation and Fusion, Microsoft Virtual PC, and Sun xVM VirtualBox.

How and why is this possible? Read the rest of this entry »

I stumbled across another interesting Perl script. Paul Gregg – Projects – VMware ESX vmclone.p is a web page that explains the vmclone.pl script which automates cloning a virtual machine. Not a big deal if you have Virtual Center, but for those environments where you have stand alone ESX hosts this script can make life a little easier.

From the web page and the notes of the script: Read the rest of this entry »

From Vizioncore’s web page (linked below):

“vConverter is an enterprise-class conversion solution that significantly reduces the time and effort spent converting servers to the VMware, Microsoft, XenServer or Virtual Iron platforms. vConverter enables lightning fast and easy conversions without disrupting the source physical system during the conversion process. There are never any reboots, no need to visit machines being converted, no software to install on the source and no downtime. A significant R&D effort and focus on conversion reliability and efficiency has resulted in the fine tuning of read/write/transfer algorithms and the creation of several mechanisms which result in impressive speed and conversion completion metrics. Combined with an impressive simultaneous conversion capability, vConverter is ideal for medium to large server consolidation initiatives where hundreds or thousands of physical servers need to be virtualized. vConverter can migrate more servers per conversion window than any other conversion method or technology, dramatically reducing risk, cost and time from start to finish.”
