CPU and memory

vtAlpha-GS can virtualize any AlphaServer GS system from 1 - 32 CPU's. The Base License includes support for one CPU to which additional CPU licenses can be added.
vtAlpha-GS supports up to 256 GB of virtual Alpha memory.

QBB (Quad Building Block)

The AlphaServer GS system architecture consisted of QBBs, each of which supporting up to 4 Alpha CPUs, 32 GB Alpha memory memory and 32 PCI slots. Depending on the GS-model (GS80, GS160, GS320) it could contain 2, 4 or 8 QBBs; this architecture is emulated in vtAlpha-GS.

Emulated GS-models

vtAlpha-GS can virtualize the AlphaServer ES80, GS80, GS160, GS320 models. It also can replace AlphaServer GS1280 models with up to 32 Alpha CPUs. Support for 128 CPU Alphas is not necessary since these systems were hard-partitioned into smaller logical machines with maximum 32 CPUs.

Supported Alpha operating systems

  • OpenVMS 7.2-1h1
  • Tru64 4.0G

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 never originally supported by the OpenVMS or Tru64 operating systems on the AlphaServers.

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 Alpha Ethernet adapter types. Virtual adapters can connect to a host Ethernet adapter or share a single host Ethernet link. 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 is also supported.

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-GS, we recommend a X86 Server with an Intel Xeon E5v4 or E7v3 processor and a CPU frequency of at least 3 GHz.

See Host Computer Recommendations for more details on the sizing of the host system.

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 compatibility reasons.

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.
