HP CIFS Server Requirements and
Limitations
Prior to installing the HP CIFS product, check that your system can
accommodate the following product requirements and limitations.
HP-UX 11.0 Memory and Disc Requirements
Although an 11.x 32-bit and 64-bit HP-UX system can boot with as little
as 64MB RAM and 1GB of disc space, the performance of such a
configuration would be prohibitive. The HP recommended minimums are
as follows
• 11.x 32-bit: 128MB RAM, 1-2GB disc
• 11.x 64-bit: 512MB RAM, 2-3GB disc
Updated HP CIFS Server Memory Requirements for versions A.01.05
and later.
As of version A.01.05, the HP CIFS Server processes increased their base
use of system memory by 20 percent. This represents an increase of
approximately 100KB per smbd process over and above a base of 500KB.
The increased memory footprint is the result of new caching mechanisms
to improve performance.
In addition to the base memory increase, the smbd process may now also
allocate memory for specialized caching requirements as needed. The
size and timing of these memory allocations vary widely depending on
the client type and the resources being accessed. A single smbd process
may temporarily use up to 2.5MB of memory. However, most client access
patterns will not trigger such specialized caching. System administrators
should routinely monitor memory utilization in order to evaluate this
new dynamic memory behavior.
You may need to adjust HP-UX server memory configurations to
accommodate these changes when upgrading from previous versions
