Storage Adapters
CHARON-AXP/SMA(+) provides emulation of the KZPBA UltraSCSI PCI Adapter, which is based on the QLogic 1040B chipset. This can be used in place of any native SCSI-based controller.
For OpenVMS systems it is possible to install the bypass driver (a special OpenVMS disk driver) which allows emulation of DSSI (DI), IDE (DQ), FibreChannel (DG), MSCP (DU) and RAIDArray (DR) class disk devices.
At this point there is no bypass driver available for Digital UNIX and Tru64 UNIX.
Network Adapters
CHARON-AXP/SMA(+) offers emulation of the following DECchip 21x4x “Tulip” based network cards:
DE435 EtherWORKS Turbo PCI Adapter,
DE450 EtherWORKS Turbo PCI 10 Adapter, and
DE500-BA FastEtherWORKS 10/100 PCI Adapter.
CHARON-AXP/SMA(+) provides a complete emulation of these devices, meaning that any network protocol working on an existing native Alpha system will continue to work under emulation. This includes, but is not limited to DECnet, TCP/IP, LAT. MOP and SCS.
The actual network speed depends on the CHARON-AXP/SMA(+) hosting server network speed and hosting server performance as well as on VMS or Tru64 network stack and applications, and may exceed 100Mbps when working over 1Gbps / 10Gbps network.
Communications Adapters
The CHARON-AXP/SMA(+) emulators are capable of emulating the standard two serial ports present on most Alpha systems as well as the following serial line adapter:
PBXDA-AB Digiboard RJ45 to MMJ 8 pack adapter
CHARON-AXP/SMA is also capable of emulating a parallel port.
It is possible to connect these emulated serial and parallel ports to TCP/IP ports or native serial and parallel adapters attached to the host system.
In situations where the emulation of serial devices is insufficient, it is often possible to replace the directly connected serial ports with a networked DECserver or terminal server.
Graphics Adapters
At this point there is no support for an emulated graphics adapter. Almost all graphical applications used under Tru64 UNIX and OpenVMS are implemented using the X-Windows, CDE and Motif environments. To support graphical environments it is necessary to install an X-Windows server and connect to the guest over a network connection.
Optical Drives
The CHARON-AXP/SMA(+) virtual machine is capable of emulating an RRD47 SCSI CD-ROM. This allows you to connect host attached CD-ROM devices as well as file based containers (or ISOs) to the virtual Alpha system.
Disk Devices
CHARON-AXP/SMA(+) is capable of emulating a generic SCSI disk device. Through the manipulation of various configuration parameters it is possible to modify all details of the disk device presented to the virtual machine. These virtual disk devices can be both container files on the host file system or physical disk devices attached to the host system.
The CHARON-AXP/SMA(+) virtual machine also emulates an RX28 floppy disk drive.
Tape Devices
CHARON-AXP/SMA(+) is capable of emulating a generic SCSI tape device. This virtual tape device can be connected to a file based container, on the host file system. Alternatively, it is also possible to attach a physical SCSI tape drive connected to the host system. This includes DDS, DLT and SDLT devices supported by the guest operating system.
For OpenVMS Alpha guests, CHARON-AXP/SMA(+) ships with an installable Tape Control Utility. This utility makes it possible to create, load, unload and delete virtual tape container files on the host system, from the guest.
