Sharing physical storage with windows-server
Hello
I got this configuration:
5 ESX 3.5 servers connected to a HP EVA 5000 zFCP SAN.
1 physical SQL Server with 4 LUNs
1 virtual Failover SQL-server with the same 4 LUNs as Raw Device Mapping
It works fine, with one major flaw:

When I look in/vmfs/devices/disks, I see that these vml files are the LUNS for the SQL cluster. I guessthe physical windows-server reserved LUNS.
The problem is that a new analysis of the host bus adapters takes to always (5 minutes), but works.
The major problem is that I can not add new storage VMFS to the esx cluster. I get this message when you click "Add storage...". » :
The query failed because the remote server has taken too long to respond
Are there best practices available for LUNS between ESX and other sharing systems, or best practices to not do? (It works of course..)

ProLiant DL320e with Windows Server 2012 Bluescreen
Hello
I installed Windows Server R2 with smart supply a Proliant DL320e Server 2012 R2 and it bluescreens much. The blue screen message is a pretty no description "KERNEL_SECURITY_CHECK_FAILURE".
I installed a second Proliant DL320e server and it shows the same behavior, so I conclude that this isn't a defective hardware.
I found some knowledge which mentions screens blue and with the driver for Smart Array
http://h20628.www2.HP.com/km-ext/content-webapp/document?docid=emr_na-c03793656 & DTD = default & local = d...
But the update and version numbers do not match.Drivers, software and firmware for the HP DL320e Gen8 ProLinat Server Page did not all downloads for my OS-, but it displays a warning that it is experiencing problems.
I tried to fill in the HP Support Assistant, but I got an email in response, telling me that they are currently unable to help with e-Mail support.
The servers are offline on a clients site in a restricted environment so that they lack updates online.
During this time, I downloaded the SPP Service Pack for Windows Server
FTP://FTP.HP.com/pub/softlib2/software1/CD-generic/p652182553/v84427/SPPMDSLWIN2013090.2013_0830.7.i... and today, I'll try if it corrects the blue screens.
Does anyone have pointers?Take care
Martin
Thank you, I have not found this forum. If an admin could move it which would be best.
Just in case anyone else has this problem is this question:
I contacted HP by telephone support and the solution is:
Do not use smart supply when you configure your server, it is not supported and it will be randomly bluescreen with Windows Server R2 2012. You must install windows directly, so take your storage driver and copy it to a usb key and load the driver during the installation of windows. In my case I needed to use the mass storage drivers for Windows Server 2008 R2 from http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=5293151 & spf_p.tpst = swdMain & spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253DMTX_9b5424c852a54e49b501e280e5%257CswEnvOID%253D4064%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument & javax.portlet.begCacheTok = com.vignette.cachetoken & javax.portlet.endCacheTok = com.vignette.cachetoken

ACS any Version with Windows Server 2008 R2 64-bit domain controller
Hi all
Is there any version of ACS is currently working with Windows Server 2008 R2 domain controllers?
Our server controls has recently upgraded domain controllers to 2008r2 and off 2003 servers. This did not our ACS 4.1.4 really happy.
I read now serveral messages about problems with the ACS and Server 2008r2 and hope to find a solution (not to mention that switching to LDAP, yukk).
Thank you
Pato
ACS currently cannot be installed on a server running Windows 2008 R2.
As an alternative, you can install ACS on a member server. Authentication
ACS uses the local machine net API authentication both compared to a 2008
R2 domain will work. The Remote Agent can also be installed on a 2008 R2
Server if you use devices.
If you install ACS on a member instead server here is how to configure services
to authenticate properly with the domain:

CHM compatibility with Windows Server 2003
I just finished creating the first version of a help with RoboHelp HTML CHM file, and it works fine on the machine, I used to write, as well as several others. When I tried the consultation on our production machine, running Windows Server 2003, I received the good Table of contents and Index, but all pages display the error "cannot display Page"standard. Right click on the page and selecting Properties said it had res://ieframe.dll/dnserrordiagoff_webOC.htm.
I checked the specifications of RoboHelp, and indeed, the standard version of RoboHelp is not compatible with Windows Server 2003. However, I had assumed that this meant that I couldn't run the program on a Windows Server 2003-based computer, not that I couldn't run to the exit.
This error is caused by a compatibility problem? It would help to upgrade to Server edition, or resign myself to use separate HTML files? Or is it another problem?Hi, Sydney, and welcome to the forum,
The problem you described usually occurs when you view the contents of a file .chm remotely over a network and are due to security restrictions that Microsoft introduced in 2005. See this article for more information and workarounds:
http://www.Grainge.org/pages/authoring/chm_mspatch/896358.htm
So the solution is either to move files .chm on a local drive or to implement the registry changes that are described in the article (on your local computer and not on the Windows 2003 Server). The best way to make these registry changes is to use the free HHReg utility, which is available here:
http://www.EC-software.com/products_hhreg.html
To answer your question, however, I do not think that there is a difference between Windows Server 2003 and other versions of Windows as .chm files are concerned.

Performance issues with Windows Server 2008 host
Hi all
If I use a Windows Server 2008 host on my ESXi 4 installation. I've recently upgraded to version 4 and had previously experienced similar problems and 3.5. I also improved the hardware in the virtual computer to version 7 on all my guest OS. The host in question is a file server. Essentially what happens is sometimes that if a user opens a document (for most of the audio and/or video documents), the media file will take a minute or two to load then jump during playback. If it's something like a file PDF/Word/Excel, the respective program crashes when the file loads or changes are saved, taking about a minute to respond to the user to enter again. This problem is also very sparadic. I even had this problem occurs when I'm the only user accessing the file server. The specification of my VMware host is 3.2 GHz Xeon dual processor and 7 GB of RAM. Two data warehouses are hosted on internal SATA hard drives. ESXi is on the build 219382. VMware tools is installed and update on all guest OS so far. With regard to the use of the resources on the computer host, the memory usage with all my virtual machines running is almost always around 5.2 GB on the 7 available and the CPU usage is usually around 2 GHz.
Looking at the logs performance monitor, I noticed an increase in the use of the disc during the shutdowns. Are there utilities built to test the internal hard drives to find errors? If this isn't the case, anyone recommend a utility that I can use to do this?
Other ideas are also welcome.
As mentioned disk SATA performance is less than ideal, or even acceptable by many people. The SATA drives in a configuration having non-RAID which makes it doubly Yes. If they were at least in a RAID 0, 0 + 1 or 5 configuration you would have best performance among readers (would be loath to 0 though, since there is no parity involved).
Using the means on board mode SATA drive controller (or not RAID) of the SATA it runs the performance as low as possible.
I wouldn't have even thought to have a server, or a system, used as a server that does not use RAID functions at least for redundancy. Couple that with discs that aren't going to cause bottlenecks as a standard too. Who used to refer to SCSI drives high speed, but also means using SAS drives these days (since they are replacing older parallel SCSI drives). The most difficult configurations for ESX, are performed on the server class hardware, which has access to a shared storage (which is high performance) on a fast network (Go to our days, or fiber) or a RAID array internally, which will not cause performance problems.
You can try setting the server configuration, you have now, but that will only take you so far. You will need to the major weak links in the system. A (a major) is the SATA storage as stand-alone drives. The other is a network of 100 MB, which isn't too bad, but is still a performance hit when you share all traffic with these two ports. Moving to a GB switch could help the part of the question, but you will still have to solve problems of disk performance. If there is a decent amount of shared storage attached network where you are, see if they can give you a reasonable amount for the servers you are running on the host computer. Of course, you'll want to also be on the fastest possible network/connection of this storage.
