Allocation of resources for ESXi v5.1 host host-level default system?

• Allocation of resources for clients... a necessary model response.

  I do not do this for work, I'm just messing around with ESXi for fun at home.

  So I tried to read all supply vCPUs for customers. But I don't really get it. Are there any simple directions, cheatsheets, etc for the supply?

  In fact, my questions are:

  During the introduction of vCPUs? Bad idea?

  Must I leave 1 free kernel for the hypervisor?

  Must I leave any free RAM for the hypervisor?

  Sorry if these are stupid questsions. It is the first time I play with hypervisors from type 1, so there is a huge gap in my knowledge.

  Thank you!

  Welcome to the community,

  If it was that simple, you'd probably find a lot of blogs etc. covering essentially overcommitting resources (CPU, memory) is a great feature that allows to use resources effectively. The majority the VM do not need all the power of the processor, nor do they always have the entire memory that was. ESXi is a very good job on the management of scheduduling and the CPU memory. According to the actual workload of the virtual machines, you will need to know how far you can go with overcommitting resources.

• vMA for ESXi on each host?

  Can I install the unit of MAS (and all other management devices associated with) on EACH host ESXi?

  I did find something that explains it... or I looked in all the wrong places so far

  Thank you, Tom

  Hello.

  You have a cluster DRS, HA and several guests or simple hosts?  If you have a cluster, then simply set up a vMA and let HA and DRS take care of it.  Otherwise, it would be wise to have several deployed, where you lose a single host.

  Good luck!

• Creating a second resource for messed up AD right to target AD system

  Hello

  I'm running on IOM 11gr2ps2.  I have a need to run that the announcement of trust reconciliation source and AD target reconciliation system pointing to the same instance of AD, on a daily basis.

  A team member creates a new resource IT (AD target recon system) and set the search so that the resource would be used for the reconciliation of the target system.  Although the idea was good, but the execution did not correctly because unit testing was not performed.  I later discovered that target reconciliation for a given user will no longer display payments (for ad groups).  Reconciliation data shows the ad groups reconciled.  The database displays the correct ad groups.  However, the right tab in the user record was empty.

  When I opened the Application instance, I noticed there were 2 instances of the application to AD.  Instance of the reliable source AD app has a tab named 'Entitlement' with all the values.  However, the application system AD target, right tab instance showed no value.

  How can this be repaired?

  Thank you

  Khanh

  You want to fix the search that has ad groups.  You can clear the list, and then run the task of reconciliation of Group research.  In the scheduled task, use the resource your Recon target is configured for.  Once done, run the scheduled task from the eligibility list and that will also trigger the catalog synchronization task execution and until it is enabled for updates, which will correct.

• Correct allocation of resources to VM CPU with hyperthreading VCPU ESXI 5.5

  Hello

  I've read various articles on trying to size of the allocation of CPU for virtual machines and performance of subjects with overcommitting, but still can't seem to find a definitive answer with hyper threading involved for this particular configuration and hoped that someone could clarify for me.

  Example 1 - Exchange Server 2010

  1 x 6 Core Processor (12 logic with hyper threading)

  There are currently 1 socket and 6 hearts are attributed to him on a possible 12.

  There is only 1 virtual machine running on the server. I would benefit from an increase in the nuclei of one of the following:

  1 outlet, 12 hearts

  6 sockets, 1 core

  12 Sockets, 1 core

  any other configuration?

  Example 2 - server has 2 x 6 Core processors with Hyper threading enabled. (12 cores, 24 logic)

  I want to attribute 2 physical cores to VM1, VM2 4 physical hearts and 6 physical cores to VM3

  Who would do the following:

  VM1 - 1 taken, 2 hearts VM2 - 1 socket, 4 cores VM3 - carrots 1 Socket 6

  VM1 - 1 socket, 4 core VM2 - 1 socket, 8 cores VM3 - 12 hearts 1 socket

  VM1 - 2 taken, 1 core VM2 - 2 Sockets, Sockets 4 hearts 2 VM3, 6 cores

  VM1 - 2 taken, 2 hearts VM2 - 2 taken, 8 cores VM3 - 2 taken, 12 hearts

  VM1 - 2 taken, 1 taken VM2 - 4 kernel, 1 core VM3 - 6 sockets, 1 core

  VM1 - 4 taken, 1 core VM2 - 8 Sockets, 1 core VM3 - 12 Sockets, 1 core

  any other configuration?

  No, you can allocate more vCPU you have. what you said it is fine. I usually go for a ratio of 6: 1. for example, with 12 cores, we have up to 72 vCPUS (it's all compared to the workload type and the size of the virtual machine through)

  I said that you never allocate a unique virtual machine more than the physical cores as the guest on the virtual machine OS think there full hearts to play with no hyper threaded no carrots...

  But hyper threading can give use better ability to commit the resources of the processor because it intelligently uses the additional threads when the performance will not be affected. as long as all virtual machines will not work 100%, then you can add more with no real impact. If you have listed these 3 VMs had to use 100% each you'd be using 100% CPU host not 50%. never use logical cores when it comes to calculations of ability only physical cores

• Create notification of a particular hardware for ESXi host problem?

  Hello

  One of our 5.1 ESXi hosts is constantly a hardware problem (with hardware alert status).

  We would like to ask for your opinion

  (1) if we create a notification, should we use 'host' alarm?

  (2) is it possible to send a notification to the staff for this particular host with error alarm "host" other than other ESXi hosts (i.e. send to Tony and Stephen for ESXi host A Harware problem BUT only sent to Tony for another hardware ESXi hosts problem)?

  Your opinion is requested.

  Hello

  No, there is no option to select specific host in a cluster. When you set the alarm, it is fixed for the whole army in the cluster.

• BackupExec 2012 Agent for ESXi 5 host?

  We just move from ESX to ESXi 5 4.1.  We find that the BackupExec Agent of Linux is no longer talking to ESXi host 5.

  Just would like to ask you if there are any 2012 BackupExec for ESXi 5 Host Agent?

  Thank you

  As far as I know, we don't have Backup Exec for ESXi host agent. If you want to take a backup of the configuration files to can do this through the vCLI l command vicfg - cfgbackup.p

• Allocation of memory in ESXi 3.5 problem

  Hello

  Before I switched to using ESXi 3.5 to host my VM guest, I used VMware Server 1.0.6 to the guest virtual machines. However, I think that

  the VMServer could not allocate correct memory that I specified in the virtual machine settings, for example, I put 3 GB of memory to a guest

  OS, but I found that only 1200 MB of memory was allocated in the ohter handler.

  So I now use ESXi 3.5 to host 3 VMs, ESXi 3.5 host has 8 GB of memory, two of these VMs have the allocation of memory 1 800 MB and 4 GB.

  However, on ESXi console, I found that me, the 'use of memory of comments' are only 450MB and 778 MB only.

  It's really out of my expectation, it seems that the memory on the VMware product management is the same.

  Does anyone know how fix memory use such as ESXi comments will not control the dynamic memory allocation?

  In our case, it is not necessary to adjust the consumption of memory intelligently by ESXi from time to time.

  I have attached some screenshots for your reference to screen and hope that the screens are useful to explain the problem.

  Thank you for your kind attention,

  Raymond

  It is possble to use memory locking of operating system invited in a fixed allowance?

  Is called memory reserve.

  You can do this under settings of the computer virtual (tab "resources") or by using the list of resources.

• Migrate to ESXi 4.1 hosts to VCenter again

  Hey volks!

  Today, I finished with the installation of a new server VCenter 5. There is another VCenter 4 Installation that actually manages our ESXi 4.1 hosts. Now I would like to move the hosts to VCenter 4.1 environment to the new (5) a.

  Is there a way without having to move the hosts in Maintenance Mode?

  What I read on the web - can I just uninstall the agent, but no guide step by step has been found and I would prevent mistakes when doing. Also, I think that this is not a good way to do it, or?

  I'm sure someone did it in the past and can enlighten us on this.

  Thanks in advance,

  Matthias

  NAAA it should be simple. Cluster resources can be a problem, but I don't see it as a big deal,

  1. Disconnect host VC4
  2. Remove the host of VC4
  3. Add a host to VC5
  4. and repeat step 1-3 for all remaining army.

  vCenter and HA agent will be installed automatically when add you the host to the VC5

• New cluster or new pool of resources for tier 1 applications?

  Hello

  I have an existing cluster 5 node blade Esxi HP that I put in place for resource pools containing loads of pre-production and production work.  Now, we want to welcome applications from level 1 (Oracle DBs, Weblogic and middleware VMs servers).  Is there a best practice in the establishment of tier 1 workloads?  Should I add additional nodes to the cluster (until 8) and create a separate pool of resources for tier 1 applications, or should I implement a cluster 3 separate node (and generation) devoted entirely to the only level 1 workloads?  What are the advantages/disadvantages of each method?

  Thanks for your comments.

  M

  It depends on.

  (1) that you're going to develop this group even more tomorrow, or after you have added the hosts you have in mind who will be the end of the work?

  (2) how the negative risk is your boss or your client?

  (3) do you run your environment oversubscribed?

  (4) you understand the fundamentals of Resource Pools?

  Since I'm pretty risk adverse, I am tempted to create a new cluster with 4 nodes, where each node spans at least 2 or 4 chassis. Resource pools can resolve the problem of conflict of resources, but adds an extra layer of complexity to an environment that is not always welcome, and can make the diagnosis of difficult performance.

  Since you mention that you run ESXi on blades, please see the following article. I found it very informative regarding the problems of redundant N + 1 with blade configurations;

• Necessary for ESXi 5.0 RAID?

  Hi all

  I am quite new to this VMware and it's our first test of society on the implementation of the VM solution to our test environment.

  So please be generous if my question is redundant or I'm a bad advice.

  Our server is HP Proliant DL380 G5 server, and we bought the license VMware Essential Kit.  (installing ESXi 5.0 planning)

  As most of you already know, HP servers have this thing SmartStart which helps the user RAID disks before installing so that cases of dysfunction of a disk, the mirror will do its job until the fix.

  But when I was reading the other articles, it is said that esxi will not recognize software RAID?

  Also, no ESXi have some type of built in resources distribution system that allows virtual machines to function even if one or two hosts readers a malfunction?

  Corrections, suggestions and questions are welcome.

  Moreover, since it is the test environment, HP box is the only host (about 3.8 TB) and we intend to run about 4 ~ 5 VMs.

  Thank you

  Welcome to the community,

  most of the DL380 G5 models come with a built in P400 SmartArray RAID controller, which is a hardware RAID controller supported. The RAID functionality is completely transparent for ESXi in this case (for example, rebuilding after a fialure). So nothing to worry about this controller

  Regarding the size of disk/RAID you mentioned, you may need to divide the RAID in several logical volumes using the ACU (Array Configuration Utility) as a result of a problem with the currently used driver (see http://kb.vmware.com/kb/2006942). I would recommend that you create a logical volume of 10 GB for ESXi and divide the disc space remaining in two logical volumes for use VMFS data warehouses.

  BTW. the controller has BBWC (battery backed write cache)? This is very important and makes a HUGE difference in the performance of the disk.

• You want some advice on configuring NPIV for ESXi Vsphere 4.1

  Salvation; HP EVA8000 SAN/FC switches, Win2k8 servers, HBA Qlogic - environment. I have my VMware Setup and ready to go.  I have test virtual servers on the SAN and want to connect to the virtual disks of data users. I made copies of the VD data user and copies connected to the virtual machine as LUN mapped Raw. They seem to work ok, but I don't know what I have to configure for NPIV? If I do, how can I change the settings for the HBA on the ESXi host? is there a resource for the syntax and parameters? I will follow my own, but if anyone has any experience in this area (NPIV), it would be greatly appreciated. Thank you. Gregg

  There is no need of NPIV for the scenario you describe. In fact, I don't see a case of usage with the current implementation for NPIV (technically), since in addition to NPIV you must always present the LUNS to the ESXi hosts and map in the RDM.

• Installation Partition problem (allocated too expensive for the Service Console?)

  Installation Partition problem (allocated too expensive for the Service Console?)

  RAID1 (15K 146 GB SAS) on Dell R710 and VMFS is on table EQL.

  What I did during the ESX4.1 excavation, it's that I have used ALL the space in 146 GB (mainly for / and / var), after adding this ESX host to vCenter, VC and EQL ASM/VE started to complain about the following points:

  1 VC: health check of localstorage warning (only has 245 MB left on 146SAS localstorage)

  2 EQL ASM/VE: warning rootFolder folder (due to the above)

  I thought that he is authorized to use all the space for / (50 GB) and / var (50 GB) in my case for only 146 GB, I don't think I need to leave any space on the installation disc.

  Could someone share some lights here?

  Thank you

  As you can see SDS use all the SDC VMFS partition space.

  This create the alarm.

  The thing really confused me why I have to leave a space on the disk at all?

  Technically there is no reason to let the space... but also no reason to have a big service console

  Usually, you need 10 to 20% free space for each snapshot data store and Exchange files... but in your case, you will not have these files.

  If you have any problems, but you receive the alarm until you do not disable them on this specific data store.

  PS: I suggest you switch to ESXi, is quite simple and it doesn't have this strange vmdk for the "console".

• Help Setup RAID SATA for ESXi 4.1

  Hello

  It is the first time that you try to use vmware.  Any help is greatly appreciate!

  I just built a server around the Intel s5500hcvr mother. I have 6 SATA HDD I want to set up in a RAID. The integrated RAID controller seems to be very limited and does not seem to be supported by ESXi 4.1 (when I run ESXi 4.1 installation and it asks for a location for installation, all my discs are individually listed instead of virtual drives that I created with the RAID controller)

  My questions:

  (1) what is the suggested configuration of HDD (RAID levels / number of berries) for ESXi 4.1?  Can I create 1 RAID 10 array and set everything up to that?  or take one of my disks and install esxi 4.1 on it and then create a RAID with the rest of my discs and use it to store data?

  (2) anyone can provide links to some SATA RAID controllers that are known to work with ESXi 4.1 (and is the supposed to recognize virtual readers created by the RAID controller setup ESXi 4.1)

  Your motherboard has a RAID controller software which, as you have discovered, is completely not taken in charge by ESX/ESXi... You will need to get a RAID controller that is on the HCL for SAS and SATA hard drives (not one with battery backup write cache) so you can use any type of RAID configuration.

  My preference for Internal RAID configurations (on the host) are two drives mirrored for ESX/ESXi to reside (preferably being SAS 10 k or 15 k RPM, 73 GB or 146 GB in size) and then another table for the data store. You'll want to keep the data slot store table 2 TB-512 b size in order to present to ESX/ESXi as a LUN. Or you will need to get a RAID card this split of the support to the top of the table in the smaller of the virtual drives that can be presented for ESX/ESXi and LUNS.

  Search for controllers using the LSI MegaRAID chip as a good first lap. Some Adaptec cards should work, but I've seen people post questions on those recent (more recent than in the past). MANY manufacturers rebrand/efficiency the LSI MegaRAID Controllers server, such as the Dell PERC 6 series cards.

  For the use of 4 disks SATA, RAID 10 (on a BBWC, fully supported, controller) will give you the best performance. It will compare with SAS drives however. IF you do not plan on any virtual machine running with anything beyond light IOPS / s then you should be ok (or with very light loads)... If this is going to be a production server, then get the SAS drives all around.

• ESXi 3.5 host to be used as a Client?

  Hi all

  Please forgive the questioning of basic, I'm quite new on the concept and the technology!

  I installed ESxi 3.5 on a Dell T810 32-bit Tower Server, I P2V converted to a virtual machine on the same server, I can access the server via the Client assuming VI and get "on line" with VM, etc. using remote desktop etc from my laptop. However, we want to deploy this tower as a Desktop Server effectively. Is it possible to configure ESXi "Host?" as a customer, thet Gets the behavior of a normal workstation?, IE turns in this case, or at least with a few clicks, I have a monitor and Kepboard etc attached, when the server is restarted, etc. it initializes and powers up to the configuration screen.

  Thanks much for any help you may offer.

  Myles

  ESX/ESXi is virtualization "bare metal". To keep the ESX/ESXi on the host server, you will not have a 'normal' windows environment to begin directly. Even with ESXi, there is only a very limited "gui" that is displayed for the management of the essential elements/aspects of the hypervisor. The ESX/ESXi hosts are designed to reside in data centers and server rooms. Not on the desktop of an end user.

  So, no, you will not be able to deploy the ESXi HOST server as a workstation. If you want to deploy as a workstation, you need to install a workstation OS on it, destroying ESXi in the process.

  My own ESXi 4 server is probably the most powerful system in my environment. I wouldn't dream of trying to do a 'normal' job He will remain an ESXi host until I have newer, faster, more powerful servers to support ESXi features. At this point, I could convert it to a workstation (it's a Dell Precision Workstation T7400 after all).

  If you want people to have access to the server you have converted, give them the URL that is for THAT VM. Or install the client to vCenter on their desktop/workstation computer and give them access to this VM (no admin, just run/use the VM permissions right).
