I think the OP is aware of that, however what kind of application will use more than million file descriptors ? If those are the requirements of a software that will work on a standalone system, you better think of clusters, unless the application's overhead / footprint is very small.

NAME
bttape - Bootable Tape Creation utility
SYNOPSIS
/usr/sbin/sysman bttape [-ui cui | gui [-display displayname] ]
OPTIONS
Specifies the user interface to be invoked. The choices are: Invokes the command line interface. Invokes the graphical user interface.
Specific command line options that will be used to interact.
DESCRIPTION
The Bootable Tape Creation utility is used by the system administrator to create a bootable system image, that consists of a standalone
kernel and copies of specified file systems. This standalone kernel is known as a miniroot and contains the requirements for a minimal
operating system.
In the event of a crash recovery, the system administrator can boot and restore file systems from the bootable system image by using the
btextract(8) utility.
During the creation of the bootable system image, you are prompted for the kernel name, the tape device, and the type of miniroot file sys-
tem, that is, a memory file system or disk partition to be used for the bootable tape image.
You are also prompted for the pathname of the Miniroot Append file, which lets you specify which additional files or directories should be
included in the miniroot. The size of the Miniroot Append file should not exceed 360KB. You are also prompted for the pathname of the File
System Backup File which defines which file systems are backed up to tape. Each line of this file specifies one file system by its device
name, mount point, and type of file system. The bttape(8) utility provides for the creation and modification of these files.
The bttape command has two user interface options: Graphical user interface (GUI) Command line interface (CUI)
Online help is available for the bttape application. To get help, select any Help button or use the Help pull-down menu.
Running the Graphical User Interface Option:
The bttape application can be invoked from:
The CDE Application Manager Application Group: System_Admin System Admin SubGroup: Storage_Management
To start bttape from the command line, enter: /usr/sbin/sysman bttape -gui
Running the Command Line Interface Option:
To start the bttape command line interface, enter the following command from the terminal: /usr/sbin/sysman bttape -ui cui [cuioptions]
