You are on a WAN. What's the min/max/avg latency between these sites at the
time that you experiencing these delays?

Great question. Wish I knew how to troubleshoot it. Our storage guy says
there are no issues on the NetApp NAS (Unix based I think) so I have to believe
him. Ive run some perfmon stats on my citrix server and have high readings for
Redirector\Current Commands
Citrix Server
MaxMpxCt is set to 1024
MaxWork Items is set to 4096
NAS
CIFS MPX is set to 1124
Perfmon results
Redirector\Current Commands: Min 155, Max 246. Average 170
Server\Work Item Shortages: 0
Server Work Queues\Available Work Items: Min 30, Max 30, Average 30
Any suggestions on how to tweak server would be muchly appreciated
Regards
Angela

Depends what your root cause of "SMB bottleneck" if its "back end file server"
its unlikely this configuration is going to help.

Hi
We currently have 30 XenApp 5 Servers split between 2 Sites. Sites are
connected by Gig Links. At present we use Zone Preference and Failover and
Site A is Active only. Site B is for Disaster Recovery only. Site A is
running at around 75% utilisation according to Citrix Load Evaluator. As per
my previous emails we are having issues with SMB bottleneck. I am considering
removing Zone Pref and Failover and making Site B active also. Therefore all
XenApp servers get utilised which will half the resource requirements on my
servers and hopefully remove any bottlenecks.
Can anyone see an issue with running with such a config. XenApp Servers in
site B will need to cross the Gig link to connect to File Server/Web interface
but on a gig link I think should be OK. Any pro's/con's with this approach?
Thanks
Ang
