Quantum 3.5.2 manual StorNext User’s Guide 342

	General Operating Guidelines and Limitations
Operating System /
Affected Component	Description
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.”)
