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 and 32 PCI slots. Depending on the GS-model (GS80, GS160, GS320) it could contain 2, 4 or 8 QBBs
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)
vtAlpha presents the virtualized Alpha all the hardware interfaces it expects (e.g., KZPBA SCSI and KGPSA FibreChannel) and the storage devices it is used to work with.
Internally the Alpha software continues to address its regular storage structure (SCSI disks and tapes, MSA/EVA SAN) despite the fact that at the host side different technology can be used (e.g. SATA, iSCSI, NFS or modern SAN equipment).
This is all transparent for the Alpha software, which still ‘sees’ the old device types. vtAlpha seamlessly connects the old Alpha world to the modern storage equipment.
Supported Storage Devices
- Physical and Logical Disks
- Physical and Logical Tapes
- CD-ROM (Physical and Logical)
- Direct SCSI-attached devices of unknown origin
All original Alpha disk types and sizes are supported by vtAlpha.
Logical Disks and Tapes appear as regular disks or tapes, attached to one of the virtual storage adapters configured in the virtual Alpha. On the host system these will be files in directories on the host attached storage.
Physical Disks and Tapes provide direct access to physical disks and tapes by assigning a physical host disk to a virtual disk in vtAlpha. Connecting a physical Alpha tape/disk drive is an option.
CD-ROM Physical DVD/CD-ROMs as Virtual DVD/CD-ROMs (ISO images) are supported, which can be connected as CD-ROM to vtAlpha.
Direct SCSI device This allows connecting generic SCSI devices for which a custom peripheral driver is present in the Alpha Operating System.
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).
vtAlpha includes support for the two COM ports that are available on every Alpha system: OPA0 and COM2. These virtual devices can be mapped to:
- A physical VT-like device connected to the host
- Any VT-terminal emulator via telnet/ssh
- Pseudo terminal on the host's console
vtAlpha also includes support for the PBXDA serial lines adapter, that can add 8 serial lines to the two that are already available.
Host Computer Environment
vtAlpha installs directly on the host (X86 hardware, Virtual Machine or Cloud) without the need for a pre-installed operating system like Windows or Linux.
This not only assures the security and availability of your virtual Alpha installation, it also saves you the cost and effort to purchase and maintain such additional operating systems.
Everything that is required to run your virtual Alphas and control the host environment is included in the vtAlpha product. It is often referred to as Bare Metal installation.
See Host Computer Recommendations for more details.
vtAlpha creates a secure environment that can be configured by the system manager to meet the security needs of your company.
- Access roles and configurable security levels
- Secure communication protocols
- Encrypted environment in the Cloud
- Event logging and alerts (configurable)
Software License Protection
vtAlpha is a software product available under End-User License. The licenses are stored on a Smart Card device with USB connector for maximum compatibility/flexibility. This license key is only 3 mm high, limiting the risk of damage or accidental removal when in use.
The License Protection Mechanism can control multiple instances of vtAlpha inside one host computer or in a company network, providing maximum flexibility and fail-over capabilities allowing a low-cost disaster-tolerant installation.
Virtualizes one AlphaServer GS-class system with one CPU, up to 32 GB virtual memory per QBB and all virtualized devices.
Additional CPU option.
Adds one extra virtual CPU to the vtAlpha-GS Base License.
