SUMMARY
=======
 
This article lists SNA Server capacity limits related to the number of
concurrent users, logical units (LUs), and connections (PUs).
 
MORE INFORMATION
================
 
A single SNA Server supports up to:
 
 - 250 concurrent LAN-based users
 
   There are three versions of SNA Server available: 10-user, 64-user,
   and 250-user. These versions are licensed according to concurrent
   LAN-based client usage, which include any combination of named pipe
   clients (for LAN Manager-based workstations) or IPX clients (for
   NetWare-based workstations) connecting to SNA Server. Regardless of
   the version being used, these clients can use any combination of LU
   sessions and over any connection, up to the capacity limits that
   follow.
 
 - 500 concurrent dependent Logical Unit (LU) sessions
 
   This includes concurrent 3270 (LU1, LU2, LU3), LUA (LU0-3), and
   dependent APPC LU6.2 sessions (that is, those that use a non-zero
   local address in the Local APPC LU configuration).
 
   -and-
 
 - 500 concurrent independent LU6.2 sessions (that is, those that use
   parallel sessions, or any Local APPC LU that includes an LU number
   of 0).
 
   This includes concurrent 5250 sessions as well as any other APPC and
   CPIC applications which use independent APPC LU6.2 sessions.
 
 - 250 SNA connections
 
   A connection is defined to be a Physical Unit (PU). SNA Server
   supports three types of connections:
 
    - Connections to host systems (such as IBM ES/9000 and S/370 class
      machines).
 
    - Connections to peer-to-peer devices (such as AS/400s).
 
    - Connections to downstream PUs to SNA Server. In this case,
      SNA Server maps upstream LUs to a downstream SNA connection (PU/LUs)
      used by an SNA product emulating a PU 2.0 device.
