General Operating Guidelines and Limitations
StorNext User’s Guide 342
Windows On Windows systems, StorNext may log error messages after reboot if it tries
to start before some other services. For example, if the network is not yet
available, a StorNext client cannot contact a StorNext server and posts an
error in the logs. (The client will continue to retry the connection until it is
successful.)
To prevent this from occurring, make the startup of StorNext services
dependant on another Windows service (for example, the Workstation
service). For more information, see the Microsoft Knowledge Base article
Q193888, “How to delay loading of specific services.”
Windows-based SNFS clients do not support symbolic links that point to a
file system outside of SNFS. Symbolic links are created either by a UNIX/
Linux client or by a Windows client (and are referred to as junctions).
Virus-checking software can severely degrade the performance of any file
system, including SNFS. If you have anti-virus software running on a
Windows Server 2003 or Windows machine, Quantum recommends
configuring the software so that it does NOT check SNFS.
For best performance and reliability, Quantum recommends running
Distributed LAN Servers on 64-bit versions of Windows (or on Linux).
Memory management limitations in 32-bit versions of Windows affect
Distributed LAN Server performance. Due to these limitations, Distributed
LAN Servers running on 32-bit versions of Windows are limited to 16
connections.
(Each file system and network interface represents a connection. For example,
if a Distributed LAN Server with 2 NICs serves 4 file systems to 4 Distributed
LAN Clients, it has a total of 32 connections.)
Do not use Windows Backup (the application included with Windows
operating systems) to back up the directory on which a StorNext file system
is mounted.
As of StorNext release 3.5 the Authentication tab has been removed from the
Windows Configuration utility. (For several previous StorNext releases a
messaged warned that this tab would be removed in an upcoming release:
“WARNING: Active Directory will be the only mapping method supported
in a future release. This dialog will be deprecated.”)
