Examples of Block Structures
Examples of Block Structures
If you want to add two processor enclosures and two I/O enclosures to your system,
you can combine them into four, three, or two blocks.
Four Blocks
You can configure each enclosure as a separate block, and add the blocks one at a
time:
•
Two I/O enclosures become two blocks. You add these blocks to one or two
processor enclosures that already exist on the system.
•
Two processor enclosures become two separate blocks.
Figure 2-1 illustrates how four enclosures can become four blocks:
Note. In the examples in this section, an I/O enclosure could instead be an IOAM enclosure.
An IOAM enclosure is considered a group and can take the place of an I/O enclosure in the
topology. To determine the supported group numbers for IOAM enclosures, see the NonStop
S-series Planning and Configuration Guide or have your service provider see the Modular I/O
Installation and Configuration Guide (in the NTL Hardware Service and Maintenance
collection).

Note. Your enclosure doors might look slightly different.
