12. Page 12 Hardware Components Remote I/O Module OS 2200 storage peripherals are attached through the OS 2200 Remote I/O Module

13. Page 13 Hardware Components Remote I/O Module Each of four Storages IOPs supports two native peripheral component interconnect (PCI) slots (8 total) –One PCI slot contains a controller card for the DVD –Remaining SIOP slots contain HBAs or a bridge card to an external PCI Expansion Rack with up to 7 PCI cards

14. Page 14 Architecture The Dorado 400 Series systems have a new software infrastructure layer not present in predecessor systems Internal I/O Cell Procnode Cell Remote I/O Module OS 2200 Applications OS 2200 System Architecture Interface Layer

15. Page 15 Architecture Virtualization On Dorado 400 systems, virtualization is provided in the form of the System Architecture Interface Layer (SAIL) –Includes infrastructure software consisting of Linux programs and applications –Includes Unisys extensions/modifications to Linux packages –Includes the OS 2200 emulation environment –Includes Linux Kernel* software IP EngineI/OComm Native EXEC Support FunctionsConsole Environment Control Hardened Linux Subset Note: Linux Kernel is also referred to as the SAIL Kernel

16. Page 16 Architecture Virtualization The underlying virtualization logic contains many components

17. Page 17 Implementation The Dorado 400 system software is implemented in the form of several different layers –OS 2200 –System Architecture Interface Layer (SAIL) Infrastructure Kernel –External components SAIL OS 2200 External Components

18. Page 18 Software Components SAIL The underlying software in which the OS 2200 environment executes is referred to as the System Architecture Interface Layer (SAIL) –SAIL kernel –System Control –SAIL Control Center SAIL OS 2200 External Components

19. Page 19 Software Components OS 2200 OS 2200 refers to the combination of operating system products that constitute the 2200 Series OS –Integrated Operating Environment products –Including the OS 2200 products and features –Including the 2200 Series EXEC with Dorado 400 specific adaptations SAIL OS 2200 External Components

20. Page 20 Software Components External Components External components include software external to the system cabinet –Operations Sentinel –OS 2200 Server Management Control –Client Interfaces SAIL OS 2200 External Components

21. Page 21 Software Components SAIL - SAIL Kernel The SAIL kernel provides the operational environment supporting core functions of the infrastructure –Interfaces with hardware and allows other layers to be hardware independent –Provides lock down security and other enhancements –Provides APIs For networking (sockets) For peripherals for Server Sentinel hardware APIs

22. Page 22 Software Components SAIL – SAIL Kernel The SAIL kernel includes –true multitasking –virtual memory –shared libraries –demand loading –shared copy-on-write executables –proper memory management –TCP/IP networking

23. Page 23 Administration & Operations The Dorado 400 provides a number of administrator and operator interfaces –Accessible through the Operations Server or Workstation –Associated with different functions and phases of operation –Accessible at a high level through Operations Sentinel (SPO)

24. Page 24 Administration & Operations Each interface is used for a different purpose and operator or administrator role 1.Host operating environment setup and activation 2.Host operating system console 3.Virtualization software installation 4.Virtualization software configuration and diagnosis 5.OS 2200 system setup and activation 6.OS 2200 operations

25. Page 25 Administration & Operations In practice the operator interface remains largely un- changed from the past –Host OS setup is done during installation and after stops –Virtualization software setup is done during installation and after stops –OS 2200 activation and operations are the norm…

26. Page 26 Administration & Operations The interfaces on the Dorado 400 can be compared to those on previous systems –Each is dedicated to a purpose or role –Each is initiated only when needed –Most are rarely used –Each is accessible from a common point – the Operations Sentinel Console

27. Page 27 Considerations Customers that use Exec local code or software that depends on hardware monitor instrumentation may need to change their software to run on Dorado 400

28. Page 28 Considerations Multi-Host The format of the Dorado 400 boot tape is different than on predecessor systems –Dorado boot tapes cannot be used on non-Dorado 400 systems –A Dorado 400 boot tape may be deployed across multiple Dorado 400 systems

29. Page 29 Considerations Operational Interfaces Dorado 400 system has a number of new or different Operational interfaces

30. Page 30 Considerations Communications A new communications control program, Communications Platform for Open Systems (CPCommOS) is introduced to manage OS 2200 networking

31. Page 31 Considerations System Time System time is managed (configured) through the SAIL Control Center (SAIL CC)

32. Page 32 Considerations Memory Management Memory management and allocation in the system has changed

33. Page 33 Considerations Log Data In addition to the OS 2200 log files, SAIL maintains log data in separate files The Dorado 400 system utilizes SLAR for log reduction System Log Analysis and Reports for ClearPath OS 2200 (SLAR) produces reports from ClearPath OS 2200 system log files AND SAIL system log files. System administrators can use these reports to analyze the use of the system.

34. Page 34 Considerations Console Messages Minor changes have been made to utilities and messages to reflect differences between the Dorado 400 and predecessor systems
