# SNA Server and Client RAM and Disk Requirements

ID: Q107120

###

The information in this article applies to:

- Microsoft SNA Server for Windows NT, version 2.0

## SUMMARY

### Minimum Total RAM Requirement - Server

SNA Server on Windows NT...........................16 MB SNA Server on Windows NT Advanced Server...........20 MB

The above numbers are 4 MB above the required minimums for Windows NT and Windows NT Advanced Server. Microsoft highly recommends that the server be equipped with enough RAM for optimum performance. 32 MB total system RAM has proven to be sufficient for all uses in our testing.

### Minimum Total RAM Requirement - Client

Windows NT.........................................14 MB

This is 2 MB above the required minimum for Windows NT.

### Actual RAM Occupancy - MS-DOS and Windows Version 3.x Clients

SNA Server client running MS-DOS:

- Base support for IBM PC Support functions........100K
- Base support for ISV 3270 emulator................50K
- Base support for APPC/LUA-RUI/CSV application.....50K

  SNA Server client running Windows version 3.x:

- 3270 Applet......................................525K
- 5250 Applet......................................490K
- 3270 and 5250 Applet loaded at the same time.....830K
- Base support for ISV 5250 emulator...............185K
- Base support for ISV 3270 emulator...............185K
- Base support for APPC/CPIC/LUA/CSV application...185K

The above numbers represent actual RAM used when loaded. The base support does not include the application itself (such as the IBM PC Support components) or the SNA Server API DLLs loaded by the application.

Downstream clients require no SNA Server client components; the RAM requirement is the actual memory taken by the 3270 emulator or other downstream application.

### Hard Disk Requirements

SNA Server server only............................8.0 MB SNA Server including clients.....................18.0 MB

       (for over-the-network client setup)

SNA Server client running Windows NT..............7.5 MB SNA Server client running Windows.................2.0 MB SNA Server client running MS-DOS..................1.0 MB SNA Server client running OS/2....................1.5 MB
