Conﬁguring Kernel Parameters for HP CIFS

The ﬁrst step in conﬁguring HPUX to be able to support a large number

of clients on a HP CIFS server is to adjust the maxusers kernel

parameter.

The second step involves adjusting nproc, nﬁle, nﬂocks and ninode

individually so as to allow a large number of users to be connected

simultaneously.

1. Conﬁguring maxusers

Determine the maximum number of simultaneous clients that will be

connected and add this number to the current value of maxusers.For

example, if 2048 clients are to be supported, simply add 2048 to the

current value of maxusers. Note that, unless the parameters have

been manually changed, adjusting maxusers automatically adjusts

the corresponding values for nproc, nﬁle and ninodes.

For example, if the default maxusers value of 32 is adjusted to

32+2048 or 2080 to support the maximum allowable clients of 2048,

the other parameters will be adjusted as follows on a typical system:

nproc will be increased to 8,468

nﬁle will be increased to 15,656

ninode will be increased to 9,692

If these values are found to be too large or too small for that matter,

then the individual kernel parameters can be adjusted as described

below.

2. Conﬁguring nproc, nﬁle and ninode.

• nproc: since each client will be handled by one unique smbd

process, and each process will take up one entry in the process

table, this parameter has to be at least equal to the maximum

number of simultaneously connected clients. This is a necessary

condition, but it will obviously not be sufﬁcient since there will be

others processes, including system processes beyond your

control, that will take up proc table entries. In practice then, this

parameter needs to be set to the anticipated maximum number

of clients plus the number of the other processes that will also be

running concurrent with HP CIFS.
