CPU and Backplane

vtAlpha-AS virtualizes an AlphaStation backplane with six PCI slots for virtual adapters and one Alpha CPU.

Virtual Alpha memory

vtAlpha-AS supports up to 32 GB of virtual Alpha memory allowing you to expand the memory of your virtual Alpha without additional costs.

Supported Alpha operating systems

  • OpenVMS 6.2-1h3
  • Tru64 3.2C

Clustering is supported (both OpenVMS and Tru64)

Storage subsystem

vtAlpha connects the virtual Alpha with modern storage. This allows to store the Alpha data on devices that were originally not supported by the OpenVMS or Tru64 version you are using.

The Alpha software continues to address its regular storage structure (SCSI disks and tapes, MSA/EVA SAN) despite the fact that the host side may use different technology (like SATA, iSCSI, NFS, or modern SAN (e.g. 3PAR, EMC, etc).
vtAlpha hides the technology differences for your software.

Network subsystem

vtAlpha virtualizes most Ethernet adapter types that were used in the Alpha computers. These virtual adapters can directly connect to a host Ethernet adapter or share a single host Ethernet link via an AVT virtual switch. All Alpha supported protocols will run on vtAlpha (TCP/IP, DECnet, Multinet, LAT, etc.).

vtAlpha offers extra virtual network options like the Virtual Network Switch and Bonding Devices, allowing to combine multiple virtual network links in a single host link.
VLAN connections are supported in our product.

These extra features help you to design the optimal network infrastructure for your virtual Alpha(s).

Serial lines

vtAlpha supports the OPA0 and COM2 serial ports by default. These can be mapped to a serial line or Ethernet port.

vtAlpha also supports virtual PBXDA serial lines adapters, each of which add eight serial lines to the two that are always available.

Host computer recommendations

For vtAlpha-AS, we recommend a X86 Server with a recent Intel CPU and a frequency of at least 2.4 GHz.

See Host Computer Recommendations for more details.

User documentation

User documentation is included in the product and accessible via the Management Interface in HTML and PDF format.

Software license protection

vtAlpha software is available under an End-User License. The license is stored on a physical license key (Smart Card technology) using a USB-connector for reasons of compatibility.

Multiple vtAlpha and vtVAX licenses can be combined on a single license key. The vtAlpha license mechanism is network capable and can be made available across the company network to all virtual Alpha(s) and VAX(es) in the network.
