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 AngelaFrom: andrew.wood@xxxxxxxxxxxxxxxx To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Citrix Farm performance over WAN Date: Tue, 5 Jul 2011 17:27:16 +0100Depends what your root cause of “SMB bottleneck” if its “back end file server” its unlikely this configuration is going to help. From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Angela Smith Sent: 03 July 2011 07:17 To: thin@xxxxxxxxxxxxx Subject: [THIN] Citrix Farm performance over WAN 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
