Theese are MS SQL VM's and we have done alot of testing with both HammerDB and also replays of our own workload and setting the VM's to latency sensitivity High gave us the most performance. We will not overcommit the hosts, every SQL VM will have "their own" cores.

Hi, We have a couple Dell R730 hosts with 2xE5-2699 CPU in them. Base frequency is 2.3Ghz and Max Turbo is 3.6 according to specs. Intel turbo boost is enabled and we are currently running 1 VM on theese hosts with 4vCPU, the VM is configured as High Latency sensitive. When the cores are maxxing out on the VM we are seeing a max Mhz usage of 11250 which is 2812,5Mhz per core which is 2.8Ghz. I was expecting to see 3.6Ghz since the host is only running 1VM with 4cores and the host has 18Cores (per CPU). Anyone has had any experience with this CPU and turbo boost? Is there perhaps some configuration we are missing? Regards Jonas

Hello Ghab, Thank you for your reply! The environment is way beyond 75VM's, however we do not see the need to SRM-protect more than 75VM's in any near future. What im upset about is that we are beeing force to take the Enterprise license and no option to downgrade or receive 2xStandard packs.
Hi Linjo, My information is coming from my local VMware Sales-team.. The question went from Sweden->EMEA office->US Office What we got back is what i typed in my original post. /Jonas

Hi, We have been using SRM since 1.5 years, and this was prior the Standard and Enterprise licensing packages was available. At that time we bought a 25-pack of licenses, the price we paid was equivalent to todays Enterprise licenses listprice. To my knowledge sometime during the summer VMware changed the licensing for SRM and created a Standard and a Enterprise option, with the only difference between them beeing that Enterprise is for 75+VM protected. Enterprise is 2x the cost also. The company im working with is not seeing any need to protect more than 75 vm's in any close future so we are quite happy with Standard-license and thought that we could save some money there. What we find out is chocking though, our licenses has been converted to Enterprise (without any word from VMware) and we are not allowed to downgrade them. We can't mix Standard + Enterprise in the same installation. One would think that when VMware changed licensing for SRM they would contact current customers and give them the choice to either take 2xStandard or 1xEnterprise per 25-pack licenses allready purchased. Or at the very least give the customers the choice to go either 1xStandard or 1xEnterprise.

Hello, Sadly I never found a solution. I did not have time to reg case so I did a workaround. I added a "netdom"-script which runs via vmware customization instead. Not the nicest solution but it works for us until this problem is fixxed. /Jonas

Hello, VC Version 2.5.0 Build 147633 (which is 2.5U4) I'm having some problem with my customization of Windows 2008 templates, the sysprep is running without any errors but the server never joins the domain. When I look at guestcust.log I can see that it does not even try to join the domain, no errors or anything! My 2K3 are working like a charm and joining the domain (different customization though of course). I've tried tons of stuff but nothing have worked so far. I am 100% positive that our DHCP is configured correctly and that the machine has an IP during customization. I've attached guest-log here, I also attached a 2k3_guestcust.log for reference. In that log you clearly see the domain-join step after "Deleted file C:\WINDOWS\system32\sysprepDecrypter.exe"-step. Anyone has any idea?
The SQL-instace we run in active/passive, The disk's are also active/passive, however they share the same disk controller. In the /var/log/vmkernel I see no SCSI warnings at all.

Hello, We have a MS-cluster setup in vmware on 1 physical box. It consits of 2 VM's, 1 database and 1 application server. The OS is W2K server and SQL version is SQL 2005 Standard Edition. We've had this cluster in production for over a year, last week however we updated the ESX-host with the machine on. We booted the VM's and the cluster came up fine, no problems or error messages at all.We took an extra backup of the databases and there was no problems with it so everything looked fine. Next day we noticed however that when we get high I/O on the server the SQL-server log error 170 (which is "Requested resource is in use"), SQL Error 9001. The server also log in the eventvwr "{Lost Delayed-Write Data}" error. When I google on the error's moste of the answers say that it's possible some kind of h/w error on the disk. The disks in the MS-cluster is setup with .vmdk files on our iSCSI-vmfs. The scsi-controller used is buslogic (since its W2K-servers). Has anyone ran in to something similar? Or anyone has any idea what we can do about this?

I had the exactly same problem. Upgraded a host from 3.0.2 to 3.5. Migrated a SLES10 machine with floppy device and it was set to "host". Could not power it on. After i read your thread i changed to "client device" and then it powered on. Cheers for entering an answer to your thread when you figured it out yourself! /Jonas

Hello, In virtual center on every virtual machine you can view performance charts and plot uptime there. I've plotted uptime for a virtual machine from 2008-01-01 - 2008-04-01. I export it to excel and get a graph there with all the values in the A and B column. It has one value per day and the value seems to be in seconds. The strange thing is that the number of uptime-seconds every day differ alot. Below you see an example from my export: 2008-03-04 01:00 429862 2008-03-05 01:00 503961 2008-03-06 01:00 597559 2008-03-07 01:00 689357 Betweeb 03/04 01:00 - 03/05 01:00 the uptime is 74099 seconds. Which is 20,5830 hours. Between 03/05 01:00 - 03/06 01:00 the uptime is 93598 seconds. Which is 25,9994 hours. Between 03/06 01:00 - 03/07 01:00 the uptime is 91798 seconds. Which is 25,4994 hours. During theese days the server has been online at all time. So why does the uptime have such different values? Anyone seen anything like this?

A question I have thats kind on topic regarding vCPU's and pCPU's: Are there any numbers of recommended vCPU's per pCPU in a production enviremont. Of course the number vary depeding on how CPU-intensive the VM's are. What I've noticed in our enviroment was that when one of our hosts (8 physical cores) had around 40 VM's on it (mostly single-core vms but there may have been 1 or 2 dual-core) we had alot of slowdowns on the VM's. And the VM's was not that CPU-intensive.

Hello, I'm woundering if anyone else has seen the same thing that we saw when we had DRS turned on in our cluster (now it's turned on and we use only HA). We have 3 ESX hosts and what we saw initially was that some machines was slow/unresponsive. The machines that was slow/unresponsive all was on the same host and we then noticed that we had like 40 machines on that host. compared to 25 on anohter and 15 on the last one. CPU/memory-usage was well distributed in the cluster but not machines per host. The cluster had placed all our cpu-intensive machines on the same host (the one with 15 machines). I know you can setup rules for machines that you dont want on the same host and so on but is there any other way to tweak DRS so it both distribute the CPU/memory-usage and machines per host? And also has anyone else seen this behaviour?
