vtAlpha Alpha virtualization runs Bare Metal (directly on top of the host computer) and on a Virtual Machine (VMware, KVM, Xen, Hyper-V) delivering the broadest choice in host environments. We even deliver the vtAlpha product as a VM appliance that you can easily import in your VM so you can start using vtAlpha without going through installation and configuration. Easy does it.
Virtual Machine products can offer live host migration (e.g. VMware vMotion). It allows to migrate a running Virtual Machine from one host computer to another. This is a feature that we like to support and offer to our (virtual) OpenVMS and Tru64 customers for improved resilience. We were pretty sure we could make vtAlpha survive such a live host transition, but what about OpenVMS and Tru64? These were not designed with such functionality in mind, so how would they survive the time lapse that is involved with such a host transition?
We can report that we managed to mask such an event from these older operating systems so any running vtAlpha can be transitioned from one host to another using this VMware capability. We have posted a short video showing such a transition here: vtAlpha host migration.
This capability enables you to build virtual Alpha installations with a disaster resiliency that can be better than with the original Alpha equipment. OpenVMS and Tru64 enthousiasts thought things couldn’t get better than with these operating systems. Guess what: they just did!
Proof is good, but customer confirmation is better. We have multiple customers using this capability and JCC, USA recently reported their positive experience on Twitter,
Check it out and let us know when you want to hear more about this capability.
On April 3, 2013 AVTware gave birth to vtAlpha v2.7.
Additional characteristics of this brand new vtAlpha family member:
- Support for legacy storage types (MSCP, DSSI, IDE and RAID).
- Network File Storage (NFS) included. Interesting for “on the fly” off-host backups.
- vtAlpha full system partition backup and restore.
- Email alerts to notify system management of critical issues.
- Virtual PBXDA (Serial Line Adapter) enhancements.
- Full VMware Vmotion support (migrate a running OpenVMS/Tru64 system from one host to another)
- Various improvements in the management tool.
With this new version vtAlpha shows its constant growth in functionality, again including many requests we receive from our customers.
We encourage you to keep us on the edge, improving the product by telling our local representatives about your desires and requirements for vtAlpha.
Let us know what you like to see in the next version.
OpenVMS clustering was already included in vtAlpha from the early beginning and with version 2.6 TruCluster support (Tru64 clustering) is added.
vtAlpha TruCluster support allows moving all Tru64 installations to a modern X86 host platform and form a cluster. Modern storage products (e.g. 3PAR) are supported, without your Tru64 based software knowing about it. Upgrade your storage to the latest level!
vtAlpha supports clustering via FibreChannel, SCSI and logical disks. Implementation examples:
- Replacing a hardware Alpha in a running multi-node FibreChannel based cluster. Mixed Cluster of physical and virtual Alphas
- Replacing a Alpha cluster by a virtual equivalent running on HP Proliants.
When you would like to learn more about this we invite you to let us know (contact request page) so we can follow up on your request.
Aside from being a quick and easy way to prolong the life time of your Alpha applications, applying vtAlpha can be a serious contribution to lowering your energy consumption.
We ran a energy consumption measurement between an AlphaServer of average size and its vtAlpha equivalent. The results were significant.
A four CPU Alpha Server consumed 630 Watts. Its vtAlpha equivalent consumed only 230 Watts. 60% less energy consumption by using vtAlpha!
When you combine two of these Alpha’s on a single host, power consumption will drop from 1260 Watt to 290: 75% less!
Also, the energy candle burns on two ends: power consumption results in heat dissipation, which you have to cool down again, so the gain is x 2. When you have Green Goals to achieve vtAlpha will certainly help you.
And there is more.
We have developed the Eco App, allowing vtAlpha to cut energy consumption even further. Eco App shaves another 25% of your energy consumption. It is packaged with vtAlpha, you only have to add it to OpenVMS or activate it in a Tru64 installation. There are no downsides for its use, no performance loss or anything else, so we recommend to always activate it.
Please check your vtAlpha documentation, your vtAlpha support person, or ask us to contact you.
Tractebel in Brussels, Belgium developed Tru64 and OpenVMS applications for which there is demand outside the current installed base. Using refurbished Alpha hardware for these new installations was not an available option.
Hence they looked at Alpha virtualization that enables them to run the existing Tru64 and OpenVMS software on top of regular x86-type host systems. Multiple Alpha virtualization products were investigated and vtAlpha is their preferred choice.
HP provided the brand new OpenVMS / Tru64 licenses for this installation and everything works like a charm
It shows that with the help of vtAlpha it is still possible to expand the Tru64/OpenVMS customer base, using regular x86 equipment as the host platform.
You too can move your existing Alpha installation to x86-based equipment and prolong its life-time with the help of vtAlpha.

Customers who are running multiple virtual Alphas on a single host like to share high speed Ethernet links by multiple virtual Alpha’s. Especially when running on Blade systems that most often only have very few Ethernet connections. For these customers, and the ones with many Ethernet links, we have developed the Virtual Ethernet Switch.
The system manager can create one or more Virtual Ethernet Switches that can serve multiple purposes:
- Allow multiple virtual Ethernet adapters to share a single host adapter
- Assign multiple physical Ethernet adapters to a Virtual Switch for fail-over capability
- Interconnect multiple virtual Alphas in one host without the need for a physical Ethernet link.
Depending on the line load and the capacity of the host links, many virtual Ethernet adapters can share a single host connection.
Creating Virtual Switches, adding/removing host adapters and managing these things can be simply done from the Toolbox/Network tab in vtMonitor.

With version 2.4 vtAlpha gets stronger in two different ways:
– performance increase (appr. 30%)
– the full implementation of virtual FibreChannel support.
You can now connect virtual Alpha’s with a FibreChannel SAN. The principle is simple: first we added support for FibreChannel (hardware) adapters to the vtAlpha host environment (vtAlpha v2.3), allowing you to connect the vtAlpha host to the FibreChannel SAN. As the next step we created the virtual FibreChannel adapter (KGPSA) that you can add to the virtual Alpha configurations you are using.
Image 1 shows the vtAlpha FibreChannel architecture and the capabilities it offers. You have vtAlpha changing your x86 system into an Alpha environment, where in this case you have two virtual Alpha’s running, a virtual ES40 and a virtual AlphaServer 4000. Both virtual Alpha’s have (virtual) KGPSA FibreChannel storage adapters included, like you would have in a hardware Alpha (visualized by the physical DS25 at the right hand side).
vtAlpha includes the drivers that handle the traffic with the FibreChannel adapters (FCA) in the vtAlpha host. Which on their turn are connected to a FibreChannel switch that interconnects all FibreChannel elements in your company storage architecture.
This setup leaves all options open for you, from only using the company SAN as a storage provider up to more complex Clusters based on FibreChannel. The latter you can (continue to) organize from your OpenVMS or Tru64 environment.
Image 1 could present a FibreChannel Cluster between two virtual and one physical Alpha (or Integrity, if you like). Or it could be three independent Alpha’s, connected to the Company SAN. Or anything in between.
With the full virtual FibreChannel adapter implementation vtAlpha stands out from all other solutions in the market. vtAlpha does not require any special (and expensive) hardware for the host computer, or a special precautions at the software side.
This is more work for our developers, but it is easier and better for the customers. And a lot less expensive too.

During the HP event in Vienna I attended a presentation about HP’s project Odyssey and that looked like a very interesting development to me, especially for the owners of Tru64 and the older OpenVMS systems.
In fact this is a blade concept, supporting Itanium and Intel Xeon processor based blade boards that will be seamlessly integrated in one box.
“And what does that bring me?” you might say as owner of one of these retired Alpha or VAX systems.
When you consider the combination with vtAlpha and vtVAX it can bring you a lot. Your current Alpha and VAX-based systems got a more and more isolated position due to the retired status of that hardware, but now they can be brought back in a recent and company wide platform, without changing your software.
vtAlpha and vtVAX are thin layers on top of an x86 based host computer creating an Alpha or VAX environment wherein you can run the virtual equivalent of your hardware Alpha or VAX system.
It are actually Alpha and VAX hypervisors (or Virtual Machine Managers, if you like) creating multiple Alpha and VAX systems on top of the x86 host. And that x86-host can now be part of the Odyssey infrastructure.
This means that with project Odyssey and vtAlpha/vtVAX you can reunite your older OpenVMS and Tru64 systems with your other, more current Itanium-based, HP-UX, Linux, Non-stop and Integrity/VMS systems on the same platform.
Odyssey, Hypervisors, Virtualization, no this is not an episode of Star Trek. It is a real opportunity to update your retired Alpha and VAX installation to a more modern platform and (re-)combine it with the rest of your IT-infrastructure, with little effort.
Time to beam-up your existing Alpha or VAX installation?
We like to hear your opinion about this subject, Contact us.
The idea of replacing an AlphaServer by a virtual Alpha running on a modern and more common host computer is welcomed by most IT managers. The concept of computer virtualization is a functional and financial very attractive solution. The main advantages are that Alpha virtualization is a very quick and inexpensive way to move your existing applications to a newer platform.
It lets you prolong the lifetime of valuable and important applications by replacing the supporting hardware platform. Not having to change your delicate and expensive software is a very important benefit.
The importance of their applications makes people very wary when they hear that potential solutions run on a foreign operating system like Windows or sometimes Linux. The main concerns focus around security and reliability.
Alphas and VAXes are known to run uninterrupted for years in a row, so their successor faces the same expectations. A foreign host operating system is a reliability risk since the virtual Alpha has no control over it. Changes made to the host operating system are outside the scope and influence of the virtual Alpha. Bug-fix or service pack updates of these host operating systems sometimes cause compatibility problems with the execution of the virtual Alpha. This can result in undesired down-time for the virtual Alpha system(s).
vtAlpha addresses these concerns by running the Alpha virtualization native on a standard x86-type host.
Bare Metal Approach
vtAlpha can run directly on the x86 host. The product includes a Host Hardware Manager that supports a broad range of peripheral devices. This ensures the support of most available x86 related peripherals.
It is an x86-based Alpha, a unique proposition.
vtAlpha also runs on virtual machines. Virtual machines are increasingly becoming the IT infrastructure of choice with our potential users, therefore our solution is designed to support that environment.
In fact vtAlpha has the broadest range of host system support available:
- It will run directly on the physical host hardware
- It will run on virtual machines
