• Virtualization of servers of very large files

  Hello world

  As the subjects that I found on this topic are quite old and advanced capabilities of ESX, I create a new.

  We are now virtualize most IS infrastructure, on ESXi servers connected to the SAN storage with Enterprise Plus licenses.

  In the list of servers, we have 5 major plysical Windows file servers, with millions on the files for 2 to 5 terabytes of data according to the server.

  Technically, we could create several large 2 TB vmdk files and use the Disk Manager Windows agregate volumes.

  Backup of all servers is accomplished using Veeam Backup and replication, to quickly perform a full backup and restore of servers (current solution is TSM, and a complete restoration of the largest server is estimated at one week that we use only redundant backups of files).

  However, if it is technically possible, we have not any idea of stability and performance.

  Someone knows the server virtualization?

  Even if VMware support this virtualization, it's a recommended solution?

  You will encounter some limitations to us?

  We have other alternatives to replace physical servers (for example before boxes NAS connected to SAN one allowing the equivalent functionality to windows, such as advertisements and VSS integration for users), but if possible, we would prefer to keep VMware solutions to virtualize servers.

  Thanks for any information on your experience.

  Andrew M says:

  If you really need a volume is greater than 2 TB disks dynamic comments is so in your case, the only solution.

  Don't forget to take the vmdk of LUNS in the same RAID Group (just to not add physical dependence).

  André

  I agree, however, an alternative is to mount points can be used to "Extend" the file system by mounting a file that points to another logic unit number in the file existing within the OS System.

• DMZ virtualization and network design. UCS + VMWARE

  Until now, we had a network physically segmented with internal and external vtp different areas/zones. Keys "inner area" hear a VLAN and keys "outer zone" along a VLAN different. VLANs are not propagated between different areas for security reasons, are isolated.

  Currently, we started to work with UCS + VMWARE, and we are facing difficulties. According to the previous model, if virtualize us servers within the internal battery of the UCS area, we cannot not virtualize servers within the outer external in the same UCS, since I wish to propagate VLAN switches area internal as well as for the farm of the UCS, mix. As a result, the isolation would be lost.

  I'm reviewing my network base, in order to adapt current infrastructure to the new with UCS + VMWARE, without missing any point security.

  My main point, is whether it is possible to virtualize external virtual machines and internal area in the same UCS, without compromising the security of my network.

  Could you give me some advice or design guide?

  Kind regards

  Hello-

  You are right that upward through UCS 1.4 all them VLAN should be available on the switches upstream.  However, UCS 2.x introduced a feature named "Disjoint L2."  By using this feature, you will be able to connect interconnect fabric to your internal network and the DMZ, then configure the VLANs to blades.

• VM with memory amount-> VMotion whitout interruption?

  We want to virtualize our big servers like a SQL servers with 16 and 32 GB of memory.

  My VLAN dedicated VMotion has only a bandwidth of 1 GB, is there a break on my connection on my big servers or can I VMotion like them small virtual machines?

  Is there some documents from VMware?

  Thanks in advance

  A correction to the sequence of the Dragon of vmotion events - now with the changes recorded in the bitmap are reduced during the period of the virtual machine is suspended

• Workspace of HP: HP Workspace eliminates the need for a customer to have a VPN?

  Hey everybody,

  HP workspace eliminates the need for a customer to have a VPN?

  Thank you

  Bill

  If a customer is already using a VPN infrastructure, HP workspace does not eliminate the need for a virtual private network, since HP Workspace application virtualization Server servers might need access through the VPN. HP offer a service added to a VPN integration for HP customers workspace which may require it. For purchase details, please contact your authorized HP or HP account.

• Fast food: repository shows Replication is complete - but it is not full.

  I have problems with my quick recovery of replication for a single machine.  It is a failure with the error 'Repository is full' - but no repository is full.

  The total size of the recovery points of the machine is 800 GB.  The local repository is 1.11 TB size (343 GB free).  The remote kernel has a repository that is 950 GB in size and still has no data stored in it.

  Specific symptoms:

  • The machine is protected locally and has the successful base image and perhaps other checkpoints so
  • The machine is added to the replication without use of seeds by car (done successfully many times with other big servers)
  • Replication starts, but fails - usually within a minute or two, but sometimes more
  • Error: The repository is full. Adjust your retention policy, or delete old recovery point channels to free up space or add a new storage location in the existing repository. The call to the service [servername/remote address] POST method: the repository is full. Adjust your retention policy or delete old recovery point channels to free up space or add a new storage location in the existing repository

  Other details:

  There is a connection of 100 Mbps between the sites, so we replicate generally devoid of seed readers and it takes about 24 hours.  I have it set up to have a repository by machine, and other larger machines are replicated successfully without problem.

  Things I've tried:

  • Giving the remote repository in addition to space (at one point, he was bigger than the local repository)
  • The local repository of the giving more space
  • Recreate the two repositories the remote using new names and
  • Remove and re - protect the machine using the local database
  • Deletion/recreation of replication

  I'm out of ideas.  I give another try now and he is working on the replication and has been for about 30 minutes, but just earlier today, he worked on the replication for about 50 minutes, before reporting that the repository was full.

  Version of fast food: 6.0.2.144

  Using the option of seeds fixed the problem drive.

  Specifically, what I've done:

  -Created a seed disk (in my case, I just used a file on a USB drive connected to the backup server main)

  -Says the target of replication to use the reader of seeds to start replication.  In my case, I never moved the drive, I just had the target server access information on our site to site 100 Mbps connection

  * wait 5 days for replication server to consume seed information reader *.

  -Once completed, replication off-site for this particular machine started working normally.

  As a note to anyone else find this information later: I have a strong suspicion that there is other hardware/software issues on the main backup server.  There's even a journal entry noting long access time to the backup information (15 minutes).  This may have contributed to the false errors do not have enough space on the remote repository.  I suggest check your newspaper for similar issues and addressing the people first to ensure reliable backups.

• How can I check the immutable flag using VCM?

  So the VCM is patching our Oracle Linux big servers now (thanks 5.7.2) However there is a problem.

  On some of our servers, the immutable flag is set on grub.conf.  It's simple to fix.  Just do a 'chattr /boot/grub.conf-i"and we're on our way.

  I am looking for a way to automate this...

  How can I create a compliance model to run a lsattr command to verify if the immutable flag is set on/boot/grub.conf, and can deal with a remote control?

  Appreciate the help.

  Steve

  Hi Steve,.

  First of all, it not there no easy way in VCM (using the default file structure data class) to get the little extended as immutable properties file. VCM now collects information may be collected using the command ls only.

  But, something known as a Type of custom information that can be exploited to run system commands and parse the output of the command to use the compliance data facilitate the VCM. However, please note that these data would *NOT* be available for automated remediation. If you're ok, read more:

  I guess that's for file /boot/grub/grub.conf only. I also assume you're on VCM 5.7.2.

  This would require steps below:

  (1) create a kind of personalized information (CIT)

  (2) collection of data using information on file /boot/grub/grub.conf personalized data class

  (3) check the data collection in the VCM console | UNIX | Custom information node

  (4) write the compliance rule and run the model

  (5) verify the results

  These steps are described in the attachment. Please let me know if you need further information.

  Thank you and best regards,

• A new doubt on the license - VMware vSphere Essential Kit

  Hi guys,.

  I play virtualize physical servers in the company I work (about 10 smaller servers).

  To start some tests, I bought a Dell r.620 server with two processors and 64 GB of RAM.

  I think buy just one license of VMware vSphere Essential Kit, just to test some features, management, and support provided by VMware.

  My doubt is: to support all the RAM (64 GB), I have purchase a license of the vSphere Essential Kit, or I need TWO?

  I'm a little confused on how much physical RAM memory on a single server, the vShpere Essential Kit can handle.

  OK, I know I can use a free version. But this test server will be transformed into a production server, and that the price of the vSphere Essential Kit is very good, I would buy it and start my test as a test of "production"...

  Guys, sorry for my bad English, it is not my mother tongue. =(

  Thanks much for any help.

  Hi Alex,

  Since you are doing a test on a single server so a Kit should be good at this point. In addition to Essential Kit do not fully support 64 GB of RAM so no need to buy two. Only the free versions have limits in support of only 32 GB of RAM.

  Diagram below will give you a good idea on the different Kits.

  Also, you can read about licensing and prices here: http://www.vmware.com/files/pdf/products/vsphere/VMware-vSphere-Pricing-Whitepaper.pdf

• Question about conversion Oracle in vSphere

  Hello!

  I'm new to VMware and tried to find the answer before posting here, but no luck yet.

  We have a customer who is going to be to virtualize their servers on an ESXi 5.  Current customer server running Windows 2003 R2 and includes an Oracle database.  I read the Oracle databases to work very well with the ESX, but I have not found any documents explaining the process of conversion of a physical machine.  I guess, he returned to interrupt and then oracle services by making the conversion, but wanting to be thorough, I decided to ask here.  Thank you, everyone!

  Truman

  Oracle is not different from any other database that VMware is concerned. There are many documents on virtualization Microsoft SQL so you can easily keep them high.

  But it sounds like you have things developed already - stop database services so that you know that it is consistent and let the P2V software do its thing.

  Personally, I would look for an excuse migrate to an operating system and more modern

• ESXi host does not recognize DVD-ROM USB

  The server we use as our ESXi server has no cdrom drive.  We connected to a dvd - rom usb to the server drive, but when we try to add to a virtual server, we get a message saying:

  

  Do we do anything to the server so that it recognizes the USB is attached?

  I have attached a 60 day trial that you can use.

  It appear another issue however.  We have two pieces of software running on physical hardware that use "license dongles."  These dongles hold some informaton for the software licenses and are necessary for the software to work.  How can we virtualize these servers if we permanently attached dongles?

  Are these USB dongles?

  4.1 ESXi/ESX and ESXi 5.0 supports USB device passthrough for a host ESX ESXi on a virtual machine.

• MS ISA/TMG on a security platform VMware ESXi?

  Hello

  I started last year virtualize our servers to VMware ESXi 4.1 and all running perfect.

  The only server that I've not virtualized was Microsoft Forefront threat Management Gateway 2010 (TMG server).

  But Friday our server collapsed, and I have no choice but to restore a backup of TMG on an ESXi server.

  Who then got connected to the internet to work as a gateway/firewall in 1 hour approximately, that this has been done.

  But I've always had this idea that he not great security wise to put a firewall/gateway server on an ESXi host with direct connection to the internet.

  Ofcouse the NETWORK card is attached to only this guest (TMG server),

  But my concern is really ok? or is there no direct safety problem to have my ESXi directly connected to the ISP?

  If there is no problem of security, it will be easy to simply continue to use this host and toll-free addictional on hardware.

• Storage after P2V performance bottleneck

  I recently P2Ved Windows 2000 advanced server running SQL 2000 to ESXi 4.1 U1. After P2V, the database server does not work as it should. Query that was running in 20-25 seconds on the source server takes more than 60 secods of execution and the application times out. KMOY and LVAD values are not very high around 3-5. Queue is showing 100% and he has another 80-100 applications pending. When I check from within the guest operating system, it shows high disk read queue length.

  When we check the performance on the source server, it has values queue disk high length thus but request does not meet the deadline. The source database server files on SAN LUN and VM, we use the original LUN as RDM copy. The disc has 42 percent file fragmentation. The database in question file has the size of about 35 GB and 168 k fragments. Can anyone suggest a way to solve this problem?

  PS: We have already tried the defrag, but OS cannot run the same DB file defragmentation when SQL server services are stopped.

  So here's what happened... during migration we chose HW version 7, but after the migration, it was 4. After the migration, no one noticed this (sad). But when we HW version improved to 7 lag time has been reduced. However, the length of the queue was very high but performance TSQL is ok now.

  So why the HW version changed to 4? Our hypothesis, it was to virtualize these servers using P2V 2 years back. But she didn't and when they drove back vmware tools were not deleted properly... we can see vmware tools service (automatic but not started) on the physical server, but the installation directory is missing. Thus, when we migrated it automatically changed hardware version 4. Weird conclusion but that's what I think. Or is that when you migrate win2k, converter automatically assigns hardware version 4?

  Any ideas anyone?

• ESXi and projects

  Hello

  I am an intern in a business and they have a project is to virtualize 4 servers (IIS 2 servers and 2 SQL servers)

  Pour it, they planned to buy a physical server not here are the features:

  Dell PowerEdge T710 chassis

  with a processor Xeon E55006 4 c 2.13 GHz 4 MB cache DD3 - 800

  16 GB (8 * 2) for two CPU of ram DDR3 1333 Mhz

  So, I wanted to know if it is possible to do this, only with the version of vSphere Hypervisor (free).

  Thanks in advance,

  Yvalf

  Hi Yvalf,

  Welcome to the forums.

  Pour have an order of quantities, we must compare the power currently consumed by your four servers with the capacity of your new machine.

  If your servers to virtualize are all recent machines, multi-hearts, with the gigabytes of memory and they are always saturated, your hair T710 Court will be UN. On the other hand, if you have an old Pentium with a few hundreds of mega and they do nothing most of the time, then it's royal.

  We must also look at security. By concentrating these servers on a single machine, cut off from any system failure. If applications are critical, please allow a solution of type cluster. And here at this time, the free version of vSphere is not sufficient.

  Good luck.

  A +.

• Windows licensing for vSphere Essentials all Linux virtual machines running

  We offer vSphere Essentials and Essentials Plus of application virtualization on a company that currently has 4 servers that run multiple applications under CentOS. The two products are very good values, providing important functionality at a reasonable cost. Yet, society of the end-user has some resistance to the required cost of Windows Server licenses. There is no Windows servers on this network. Even a minimal vSphere Essentials requires usually 3 Windows Server licenses (for the domain controller, vCenter server, and database server) and a SQL server license. Even when using standard licenses, the total cost of these is higher than the cost of the essential elements of vSphere. Other people deploying vSphere Essentials on Linux-oriented networks are finding ways to use a lower number of Windows Server licenses?

  vCenter Linux would be an alternative in such cases, but this project seems to be stalled.

  Thank you.

  Welcome to the community,

  If you're only going to do the virtualization of servers (not VMware View) the vCenter Server does not need to be a member of the domain, or you need a separate SQL Server for a small environment. The edition of SQL SERVER 2005 Express (included in the vCenter Server installation) is sufficient.

  While a single license of Windows (more CALs) would do.

• 51 in VM system error?

  Hi all

  Not sure if this is corect forum but I'm sure someone will put me right.

  I have a Windows Server 2003 SP2 running on a San connected to my very small ESX3.5 server supporting six virtual servers. Two of the servers have been moved on the SAN while the other remain on the local storage of the ESX host.

  One of these servers is configured as follows: Server 2003 SP2 32-bit, 2048 RAM with 2 GB SCSI disks 50 mg hard confgiured Basic versus dynamic inside Windows.le server disks host several small SourceSafe databases, but also a new software used by our QA department. This software contains a large number of small files stored in its own local database format. I'm not sure if this software is the culprit in my scenario.

  What I see is a small number of system error 51 s generated in the event log system on this server at random times during the day. Googling this error against VMs comes with questions and answers from 2005 to 2008 to virtualize SQL servers with a large amount of disk i/o. I wonder if I see the same thing, if it's really a question or if I can do some other configuration changes to help solve the problem?

  Kind regards

  Hello

  In regard to the remark of MS and not performing VM enough, it is interesting to note that MS has this kind of comments so that their own product (Hyper-V et al.) are powerful enough to properly support the MS SQL in a virtual environment. I would chalk up to MS FUD.

  in any case, I guess it of mud slinging and not very relevant to the discussion.

  For a more relevant counterargument, take a look at this article from VMware performance group:

  http://blogs.VMware.com/performance/2008/05/100000-IO-Opera.html

  Or for a report of no vmware, take a look at this study of Brocade:

  http://www.Brocade.com/downloads/documents/white_papers/WP_VMWareSQLServerBenchmark-00.PDF

  Using virtualization and bays of external storage, you can stagger out better as simply assigning the entire machine to SQL Server, and assuming that you get the same scaling performance upward. So by applying good configuration you can actually get more performance from your hardware in the VMS as using physical hardware.

  With regard to SQL2000, SQL2005 vs. I do not know your application and SQL 2005 is if I remember correctly - that's all right now-backward compatibility with SQL 2000 almost everything. I'm a database developer, but use about any server SQL, not only the products of Ms.

  The reason why I mentioned, it's that I don't think that even Microsoft still supports SQL 2000, so if you can improve it, would be nice. With respect to the resolution of the 51 system error report, I also don't think that this will solve, but don't really know. I can't test/check here because I have no more SQL 2000 configurations.

  Now, back to your syslog error event. Personally, I doubt it is a serious mistake and that a report of an absence of cache, but for now, I'm having trouble to back up this statement. If it's a mistake that occurs every day, then you might be able to set up some performance counters to check if the host is trading at the time of such a report.

  If I look at the log of my current VM system, I also see an error 51 error, but it's for my floppy drive.

  An error was detected on device \Device\Floppy1 during a paging operation.

  Consider that your report is for the physical hard drive? He also has the part "paging operation"?

  You have only a single mounting of hard disk with this virtual machine?
