For sake of completeness, the hypergrid is a concept both at the
logical and physical levels.<br>
<br>
At the logical level, it's a web of maps. As someone put it this
morning, it's "Mr. Spock's weird chess game" :-)<br>

At the physical level, it performs a mashup of servers; region servers
end up interacting with a plurality of glue servers, instead of just
one of each type of service.<br>

Your division of logical vs physical space is right on. But I think
this is closer to reality, though:<br>
<br>
1 Logical Space<br>
1.1 A region is 65,536 sq. meters and infinite Z space, which provides
a 3D space *service*<br>
1.2 A Map (logical grid, matrix) contains one or more regions. <br>
1.3 A collection of *services* glue the regions together. Those
services are: <br>
grid service, user service, asset service, inventory service, and
others.<br>
<br>
2 Physical space<br>
The different *services* mentioned above are implemented by *servers*.
Servers can run one or more of those services.<br>
2.1 In the simplest case, there is only one server running all the
services. This is known as "standalone".<br>
2.2 In another common configuration, one or more servers run the 3D
space service (1 or more regions per server) and independent servers
run the glue services. This common configuration is known as "grid".<br>

<pre wrap="">Here is a suggested rewrite. Hopefully, I have
not confused matters:
1. Logical Space (map) is defined as follows:
1.1 A Grid contains one or more Regions,
where each region is managed by
a different Region Server. A Grid map
is indexed by Grid coordinates.
[Example: OSGrid]
1.2 A Sim contains one or more Regions,
where each region is managed by
the same Region Server. A Sim map is
indexed by Sim coordinates.
1.3 A Region is 65,536 sq. meters, and
contains one or more Parcels
2. Physical space (architecture) is defined as follows:
2.1 StandAlone Mode is one computer running
one Sim (one instance of OpenSim).
2.2 Grid Mode is one or more computers in the
following configurations:
2.2.1 Region Server: Region servers are
defined by an instance of OpenSim, and
they are clients of the Grid Server.
[Example: a region that connects to OSGrid]
2.2.2 Grid Server: Grid servers (UGAIM) connect
the Region Servers together to form a Grid.
[Example: OSGrid servers]
2.3 Hypergrid Mode is a hyperlinked configuration
involving Sims and Grids

<pre wrap="">Rightly or wrongly, I've been making a distinction between those two
terms since using Opensim, although they're pretty much equivalent in
SL:
- A Region is a 64K area
- A Sim is an instance of OpenSim.exe
A single Sim can host several Regions; Linden tend to run each Region
in a separate Sim, so they can be split in hardware terms, but I
prefer to run my four Regions with just one Sim, and this is normal
for Opensim.
