- The UNIX platform for Lan Manager is fine. The reason to choose to
- run the UNIX version of Lan Manager (IMHO) is for the comfort of the
- administrator, and availability of hardware. If the Lan Manager adminstrator
- feels most comfortable working in a UNIX environment, then asking that person
- to run a PC based LAN may be asking for problems with motivation, interest
- level, etc. for the adminstrator. As I discuss below, performance is NOT
- a significant factor. If you have an older workstation available that is not
- being heavily utilized (because it is slower), and you can get Lan Manager
- for UNIX for that workstation's processor and OS, then no additional money
- will need to be spent to acquire a platform (you still need disk space,
- printers, and plotters).

- I am running Lan Manager 2.0 on an Intel 386-16MHZ platform. There are
- about 100 PCs in my organization and the others outside my area that want or
- need access to my server swell the user accounts list to about 150. The
- server has 10MB of RAM with 2.9GB of disks to manage. With session timeout
- set to 2 hours, a typical day will see 40-50 active simultaneous sessions,
- 30-60 open files, with server response time running sub 20ms. Swapfile size
- is initialized in CONFIG.SYS to 1MB, and it does not grow. Based on this,
- I would say that a SystemPro may be overkill, i.e. too much money. Something
- like an AST 486SE may be more appropriate. 16MB RAM will be fine, in a pinch,
- 12MB would do.
-
- In my environment, the UNIX workstations are more of a threat to the server
- than the number of PCs that it has to service. The UNIX workstations can and
- regularly do chew up so much network bandwidth that PCs and servers cannot
- get a packet onto Ethernet. We have a similar number of UNIX boxes on our
- network (compared to you). Based on our experiences, a sub-net for the UNIX
- world (with a router) would be advisable to keep network through-put up for
- both classes of users.

- Lan Manager ships with a revised edition of OS/2 1.3. Another poster has
- suggested ways to get Lan Manager running under OS/2 2.0 (i.e. install OS/2
- 1.3, install Lan Manager, detach Lan Manager using its Setup program, install
- OS/2 2.0, attach Lan Manager), but I have not tried this, so I cannot verify
- that it will work.
