3 Wozu ein VAX Emulator? Hardware ist end-of of-life (insbesondere( Disks) Service-Kosten steigen dramatisch bzw.. Service abgekündigt Portierung der Anwendungen auf Nicht-VMS VMS-Plattformen wird massive Kosten und Ausfallzeiten verursachen Für die Portierung auf Alpha-VMS fehlen oft Quellcode und Experten Automatische Code Konversion (DECmigrate,, VEST) funktioniert nicht immer Weltweit sind noch immer ca VAXen in Betrieb Invenate GmbH 3

22 VAX cluster types Real VAX CI (Computer Interconnect) DSSI (Digital Storage Systems Interconnect) FDDI (Fiber Distributed Data Interface) Ethernet (10/100, Gigabit) CHARON-VAX Ethernet (10/100, Gigabit) MSCP (Mass Storage Control Protocol) Invenate GmbH 22

23 luster interconnects (node to node) Real VAX CI DSSI FDDI Ethernet (10/100, Gigabit) CHARON-VAX Ethernet (10/100, Gigabit) On CHARON-VAX the cluster traffic is done through Ethernet which is the only usable interconnect at this time. Invenate GmbH 23

24 Storage interconnects (node to storage) Real VAX CI DSSI FDDI Ethernet (10/100, Gigabit) CHARON-VAX SCSI iscsi Windows share ATA/SATA Fiber Channel Ethernet (10/100, Gigabit) IEEE 1394 (Fire Wire) USB (Universal Serial Bus) As long as CHARON-VAX can access the storage as a //./Physical_diskx or has access to a container file on a windows file system it is usable. Invenate GmbH 24

27 SCSI The VAX shared storage CI and DSSI cluster can be replaced by a CHARON-VAX shared storage cluster like this. Invenate GmbH 27

28 iscsi The VAX shared storage CI and DSSI Cluster can also be replaced by a CHARON-VAX shared storage cluster using iscsi as a storage interconnect. Invenate GmbH 28

29 Container files A shared storage CI/DSSI replacement using Windows-shared container files. Suitable for testing or very low budget solution. Need to restart CHARON-VAX if it looses physical connection to container file. Invenate GmbH 29
