Hello all, I would like to throw out some questions about running financial real-time stuff on a virtual machine. We are running a VM with Solaris 10 (64-bit) and Thomson Reuters DTS application. The VM is running in a vSphere 5 Update 1 cluster. Extremely simplified the DTS receives real-time market data via Thomson Reuters leased line, crunches stuff and delivering custom made data out to clients on our corp network. It has separate vNICs for realtime data and to our corporate network. Workload is low on RAM and CPU, more load on NIC. Thomson Reuters themselves does not support running their servers in VMware environment at all, so they don't have any advice or best practices at all any than that running in VMware is very scary. We did do some on vSphere 4 and we did have problems with real time data. The DTS server was the only one that made it into production. The Whitepaper Best Practices for Performance Tuning of Latency-Sensitive Workloads in vSphere VMsBest Practices for Performance Tuning of Latency-Sensitive Workloads in vSphere VMs do contain some valuable info on network settings. So my questions: Anyone successfully runs Thomson Reuters infrastructure in VMware? Any particular settings, OS version etc? Thanks /Björn

Please note that an online update will probably affect your environment. I did ran the update with manual reboot and activation. It is correct in the blog post that you will only lose one ping, that happend in my environment too. But when I reseted the backup Flex-10 module all VMs lost their network connection causing some minor problems. Users had to reconnect their applications. Also, we have NFS storage so all VMs issued a time out on disk. No reports on crashed VMs though. I will activate the other module off hours. Until then I have one module with 3.15 and one on 3.51. Not optimal but I don't want to disrupt any work.

Thanks for the links. I will plan an upgrade ASAP, will post here if hang issue is resolved with new firmware. Might take some time though, I must also remove some old VC-FC modules/HBAs before upgrading. Want to remove possible factors that might genereate problems. Anyone has any experience with firmware version 3.51? Buggy or stable as a rock? Thanks,

Ok, the VLAN problem - did you have problem with BL620c not booting? Hangning when loading be2net? I double checked server profile. We acutally had non active FC HBA connections (no iSCSI though) but I deleted those. Unassingned the profile, assigned it again and booted. Still hangs when loading be2net... longshot that did'nt work. So it's probably VC upgrade that remains I guess. Can you upgrade VC modules without disruptions on NICs (NFS and network)? Thanks

Hello, Sorry forgot to mention that we use NFS only on storage and a trunk to regular network of course. No iscsi adapters defined. After reading blogs etc I get a bit hesistant to go for the new firmware, seems that some new versions contained many bugs. How is 3.30 working for you? Thanks

Hello all, I have a problem with all of the six new BL620c G7 we recently bought. My problem is that ESXi 5 hangs during reboot while loading be2net driver. This problem occurs randomly during reboot only and it hangs when loading screen says "Loading module be2net..." The problems fits into http://kb.vmware.com/kb/1033314 except that the KB only is about 4.1. No other problems, never looses contact with vSphere Client as some KB suggests. I have updated be2net driver to HP latest version and firmware. Blades are up to date according to the latest Smart Update Firmware DVD 9.30 except for NICs who are upgraded to: Driver version: 4.0.355.1 Firmware version: 4.0.360.15 Onboard Administrator: 3.32 HP VC Flex-10 3.15 (a bit old, I know) Anyone seen this? Any suggestions? Thanks. /B
Strange, it seems just to be working now. With some delay, but witin the minute. Earlier tests went several minutes after schedule. Well, thanks for you help!

Thanks, but vCenter (via Active Directory) and all the ESXi 4.1 hosts are syncing against the same NTP server. And since we only have ESXi hosts time zone cannot be set, it's converted from UTC in the vSphere Client. Any other suggesions on why scheduled tasks does not start automatically? thanks /Björn

Hello all, Stuck with Scheduled tasks. Googled, RTFM'd, searched forums - nothing. Tested on vCenter 4.1 and on a 5.0. Logged on as Administrator, vSphere Client runs as administrator etc. This happens: - Create scheduled task (tested both power on VM and storage vMotion) - Set task to run once, at a time - Nothing happens at that time If I click run it properly executes the task. One thing that struck med was that ESXi 4.1 has UTC time, vCenter and my client is two hours ahead. But I cannot schedule a time in the past. I must be able to schedule tasks in a shorter time window than 2 hours. So no luck there. I also went through vCenter settings, client settings without finding anything. Any suggestions? Thanks /B

Hello, I'm currently building powercli scripts for configuring my esxi hosts. It has been a very positive experience so far! The hosts are installed with a kickstart script where serial, ip, dns and hostname are configured. The problem is that i must edit ks.cfg or make an unique version for each host. It would be much better with a very simple scripted setup where the host is assigned a random name and a dhcp settings. Then my powercli script configure ip, dns and host name. I cannot find out how to configure the "dns and routing" settings with powercli. Is that possible? Or am I stiil forced to use kickstart or vcli for some settings? Thanks! /björn
