• Best practices... VCenter

  Buenos dias,

  Llevo UN my intentando realize the best practica para el stage as voy a comentar, read y releido documentation y foros, y aun no me claros some basic concepts like that Creo. A worm if alguien me los you can row.

  Tengo 2 Servidores Proliant essential vmware con. Cada uno tiene 44GB RAM y 6 red cards.

  The tests we are doing crazy cabinas office. Estamos con probando P4000 VSA (left) y Stormagic. (OL me will an aconsejar cabinas are physical I designed). Pero este're mi laboratorio.

  Y estas son put dudas:

  1 - if alguien conoce estas 2 cabinas. Cual how you look? El precio creo that are similar.

  2 - Instalo los ESXi 5 en memorias PEN. I have 2 por equipo. Las puedo clonar y comprobe than injerto works perfectly. Lo hago para no disco malgastar is para tener una copia del fair rapida. Is buena opcion?

  3 - where instalar Vcenter? This is one of the set large dudas. If instalo stormagic, be replaced by Recomiendan that part of los 2 servidores tenga a failover donde instale Vcenter haga PC y Stormagic.

  Para esto El otro windows 2008. Instalarlo como sin if instalo Vcenter for windows, no soy capaz configurar solapa LDAP, AD. ¿Pero para that voy a instalar en AD a PC if el driver del dominio goes a ser una las VM than instalare in los servidores?

  Y las VM not las puedo instalar hasta as tenga las cabinas office. (El pez that muerde cola). If lo instalo con el device of suse. El instalarlo como una VM for example el Vmware Workstation en PC, porque luego tambien el instalar el software stormagic en este windows y corre.

  A mi me gustaria instalar todas las VM, in las cabinas office. Pero me is the duda el TR VCenter instalarlo directly in el servidor, y luego clonarlo al otro servidor sin ser virtual cabina, instalarlo en PC...

  Algo parecido me pasa con el Lefthand VSA.

  3 - ¿Mejor VCenter para windows o linux device? Salvando problems than waiting antes con LDAP. ¿Mejor en los servidores o los servidores dentro fuera PC? Case of ser fuera. ¿Cuanta RAM?

  Gracias y saludos.

• Best practices ESXI 4 DRS

  DRS allows guests to get to very high processor use before moving the virtual machines. The question is, customer MANAGER has read only access to vcenter. He sees that some ESX hosts are constantly, getting CPU usage up to 98% with a warning on the host. He wondered about this.

  I'm not aware of the harmful effects on the production environment, but it's a bit noticeable when displaying the cluster on the hosts tab. Sometimes four of the sixteen hosts have a caveat during production hours. The attached picture shows a typical morning, with some hosts to 98% and 50%.

  The cluster has a capacity of 11 guests on the 16 failover, but we have very busy periods.

  Is there anything that can be done to configure things differently from the DRS? We could use Affinity rules to keep busy VMs on different hosts?

  Among the DRS Best practice:

  (1) in deciding which hosts in a DRS cluster, try to choose hosts that are as homogeneous as possible in the processor and memory. This ensures the stability and predictability of performance higher. VMotion is not supported on hosts with incompatible processors. So with heterogeneous systems that have incompatible processors, DRS is limited in the number of opportunities to improve the balance of the load on the cluster.

  (2) where multiple ESX hosts in a DRS cluster are compatible VMotion, DRS has more choices to better balance the load on the cluster

  (3) do not specify affinity rules unless you have a specific need to do so. In some cases, however, specifying the rules of affinity can improve performance

  (4) allocate resources to virtual machines and pools of resources with care. Be aware of the impact of the limits, reserves and overload of virtual machine memory

  (5) virtual machines with smaller sizes of memory or CPU virtual less offer more possibilities for DRS to migrate them to improve the balance on the cluster. Virtual machines with larger memory or virtual CPU add more constraints in the migration of virtual machines. Therefore, you must configure only as many virtual processors and memory for a virtual machine as needed.

• Best practices for the reader to 'Data' between VM?

  Hello

  So on my box ESXI, I have a 250 GB drive. I was wondering what the best practice is to have a 'data' drive shared between VM? I'm pretty new to virtualization so would like to view

  I would basically following drive configuration...

  Win 2008 R2 - 60 gb

  Win 2008 R2 - 60 gb

  Ubuntu 10.10 - 20 GB

  (Shared between the two areas of 2008) DATA - 100 GB

  Thank you.

  The only way to do this is to assign the drive to a virtual machine and create a network share. Unless you use a file system that supports concurrent access to files, an attempt to present the disk to several systems would probably end by the corruption of data.

• What is the best practice for the double management interfaces?

  Hello community!

  I'm upgrading to a few host ESX to ESXi 4.1U1 4.0 in the coming weeks. My question is about how to configure the management networks. Obviously in ESX 4.0 Classic I have a Service Console port (on vSwitch0) group and a group of ports VMkernel (also on vSwitch0) which provides my host with SC and vmotion capabilities, as we all know. Note: my vSwitch0 has two vmnic attached to it, is pending and is active. That's just how we have our double installation of switches, so it must be active / standby.

  I got to thinking (book the great from HA and DRS deepdive Duncap Epping and Frank Denneman), that I should consider carefully when my network mangement I improve these hosts to ESXi 4.1 - which of course done away with the Service Console and use the vmkernel instead.

  The question is, in which best practices and account with my setup: I have two vmkernel ports? If so, how should I configure each for traffic management and vmotion vmkernel?

  I think it will be a good discussion to have.

  Thank you all,

  Matt

  The NIC vSwitch0 value active/active, the vswif (and future vmkernel management) team of NIC Active vmnic6 and vmnic1 ensures and leaves the vMotion vmkernel NIC team as is.

  This will allow you to use two physical network interface cards at the same time while having a failover plan and keep your physically separate management and vMotion traffic.

  In the end:

  vSwitch: vmnic1 vmnic6 active, active.

  VMK (Mgt): active eve of vmnic1 vmnic6.

  VMK (vMotion): active standby, vmnic6 vmnic1.

• Best practices for managing strategies of path

  Hello

  I get conflicting advice on best practices for managed paths.

  We are on version 4.0 of ESXi connection to a HP EVA8000. Best practices guide HP recommends setting the strategy of railways handle on Round Robin.

  This seems to give two active paths to the optimized controller. See: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA1-2185ENW.pdf

  We used certain consultants and they say that the best practices of Vmware for this solution is to use the MRU policy which translates a single path to the optimized controller.

  So, any idea what good practice is best practice? Does make a difference?

  TIA

  Rob.

  Always go with the recommendation of the storage provider.  VMware recommendation is based on the characteristics of the generic array (controller, capable ALUA failover methods, etc.).  The storage provider's recommendation is based on their performance and compatibility testing.  You may want to review their recommendations carefully, however, to ensure that each point is what you want.

  With the 8000, I ran with Round-Robin.  This is the option of creating more robust paths available to you from a failover and performance point of view and can provide performance more even through the ports on the storage controller.

  While I did of the specific tests/validation, the last time that I looked at the docs, the configuration of HP recommends that you configure each IO to the ports in the switch configuration.  This adds the charge to the ESX host, the switch to other ports, but HP claims that their tests showed that it is the optimal configuration.  It was the only parameter I wondered in their recommendation.

  If you haven't done so already, be sure to download the HP doc on configuring ESX and EVA bays.  There are several parameters that you must configure the policy path, as well as a few scripts to help make the changes.

• The best practices with only 4 cards network network

  I'm used to esx with fiber channel without configuration.  This will be my first experience connecting esx to an iscsi san.

  I just have 4 network cards on the server and wonder what is the best practice.

  I think that 2 of the 4 network cards will be dedicated to the San for HA.

  But the other 2 types of throw me a loop for.

  I know I want to console, vmotion and trunk for VLANs, but I don't think I can have all 3 on the same vswitch?

  Am I stuck with having the console and vmotion on a network card and the trunk of the other?  IE - no failover?

  Is there anyway to get console, vmotion and trunk at all exist together?

  Thank you in advance.

  If it were an election, I vote for Josh26

  Just a few additions to his recommendation:

  vSwitch0:

  2 natachasery connected to the ports of the trunk on the pSwitch (vmnic0, vmnic1)

  Service - VLANxxx - Portgroup (vmnic0, vmnic1 active standby) Console

  VMkernel Portgroup for vMotion - VLANyyy - (vmnic0 vmnic1 standby, active)

  Machine Virtual Network - VLANzzz - (vmnic0, vmnic1 active standby)

  vSwitch1:

  2 natachasery (vmnic2, vmnic3)

  VMkKernel Portgroup for iSCSI

  With the above configuration you separate iSCSI traffic, what is most important.

  SC and the VM network share a teddy and vMotion has its dedicated Teddy.

  Everything is redundant.

• Best practices for iscsi - esx4

  I am trying to determine what a good or best practice would be for this situation.  We have a Server Blade esx4 so in vmware, it is already connected to our system of back-end storage.  I want to know is this:

  Can I install the iscsi initiator on the side of the OS (software) to connect and make a second drive (d:\) in this way I can push the disc, etc.  and also still available for failover, etc...

  Or is there a different way or advised to do this.

  Thank you

  Yes, you are right.

  Create a new data store (if that's what you want to do). Present this data store for all your hosts in your Cluster. Add a new disk to the virtual machine, specify the size of the drive, and then choose where you want the VMDK to be stored. You want to store this particular VMDK on the new data store that you just introduced.

  Your .vmx file will know where to find this VMDK at startup.

  Once the data store is visible to all the hosts, then he will be protected by HA (if you have HA as a feature under license)

• Best practices Apple ID

  I help the family members and others with their Apple products. Probably the problem number one revolves around Apple ID I saw users follow these steps:

  (1) share IDs among the members of the family, but then wonder why messages/contacts/calendar entries etc are all shared.

  (2) have several Apple IDs willy-nilly associated with seemingly random devices. The Apple ID is not used for anything.

  (3) forget passwords. They always forget passwords.

  (4) is that I don't really understand. They use an e-mail from another system (gmail.com, hotmail.com, etc) as their Apple ID. Invariably, they will use a different password for their Apple ID than the one they used for other email, so that they are constantly confused about which account to connect to.

  I have looked around for an article on best practices for creating and using Apple ID, but could not find such a position. So I thought I would throw a few suggestions. If anyone knows of a list or wants to suggest changes/additions please feel free. Here are the best practices for normal circumstances, i.e. not cooperate accounts etc.

  1. every person has exactly 1 Apple ID.

  2. do not share Apple ID - share content.

  3. do not use an email address of another counts as your Apple ID.

  4. When you create a new Apple ID, don't forget to complete the secondary information to https://appleid.apple.com/account/manage. It is EXTREMELY important questions your email of relief and security.

  5. the last step is to collect the information that you entered in a document and save to your computer AND print and store it somewhere safe.

  Suggestions?

  I agree with no. 3, it is no problem with using a addressed no iCloud as the primary ID, indeed, depending on where you set up your ID, you may have no choice but to.

• Best practices Upgrade Path - Server 3 to 5?

  Hello

  I am trying a migration and upgrade of a server in the Profile Manager. I currently run an older mac mini Server 10.9.5 and Server 3 with a vast installation of Profile Manager. I recently successfully migrated the server itself out of the old mac mini on a Xserve end 2009 of cloning the drive. Still of double controls everything, but it seems that the transition between the mini and the Xserve was successful and everything works as it should (just with improved performance).

  My main question is now that I want to get this software-wise at day and pass to the Server 5 and 10.11. I see a lot of documentation (still officially Apple) best practices for the upgrade of the Server 3 to 4 and Yosemite, but can't find much on the Server 5 and El captain, a fortiori from 3 to 5. I understand that I'll probably have to buy.app even once and that's fine... but should I be this staging with 10.9 to 10.10 and Server 4... Make sure that all is well... and the jump off 10.11 and Server 5... Or is it 'safe' (or ok) to jump 3 to 5 Server (and 10.9.5 to 10.11.x)? Obviously, the AppStore is pleased to make the jump from 10.9 to 10.11, but once again, looking for best practices here.

  I will of course ensure that all backups are up-to-date and make another clone just before any which way that take... but I was wondering if someone has made the leap from 3-5... and had things (like the Profile Manager) still work correctly on the other side?

  Thanks for any info and/or management.

  In your post I keep the Mini running Server 3, El Capitan and Server 5 install the Xserve and walk through setting up Server 5 by hand. Things that need to be 'migrated' as Open directory must be handled by exporting the mini and reimport on Xserve.

  According to my experience, OS X Server facilities that were "migrated" always seem to end up with esoteric problems that are difficult to correct, and it's easier to adopt the procedure above that to lose one day try.

  YMMV

• What is the best practice to move an image from one library to another library

  What is the best practice to move an image from a photo library to another library of Photos ?

  Right now, I just export an image on the desktop, then remove the image from Photos. Then, I open the other library and import these images from the office in Photos.

  Is there a better way?

  Yes -PowerPhotos is a better way to move images

• Code/sequence TestStand sharing best practices?

  I am the architect for a project that uses TestStand, Switch Executive and LabVIEW code modules to control automated on a certain number of USE that we do.

  It's my first time using TestStand and I want to adopt the best practices of software allowing sharing between my other software engineers who each will be responsible to create scripts of TestStand for one of the DUT single a lot of code.  I've identified some 'functions' which will be common across all UUT like connecting two points on our switching matrix and then take a measure of tension with our EMS to check if it meets the limits.

  The gist of my question is which is the version of TestStand to a LabVIEW library for sequence calls?

  Right now what I did is to create these sequences Commons/generic settings and placed in their own sequence called "Functions.seq" common file as a pseduo library.   This "Common Functions.seq" file is never intended to be run as a script itself, rather the sequences inside are put in by another top-level sequence that is unique to one of our DUT.

  Is this a good practice or is there a better way to compartmentalize the calls of common sequence?

  It seems that you are doing it correctly.  I always remove MainSequence out there too, it will trigger an error if they try to run it with a model.  You can also access the properties of file sequence and disassociate from any model.

  I always equate a sequence on a vi and a sequence for a lvlib file.  In this case, a step is a node in the diagram and local variables are son.

  They just need to include this library of sequence files in their construction (and all of its dependencies).

  Hope this helps,

• TDMS & Diadem best practices: what happens if my mark has breaks/cuts?

  I created a LV2011 datalogging application that stores a lot of data to TDMS files.  The basic architecture is like this:

  Each channel has these properties:

  To = start time

  DT = sampling interval

  Channel values:

  Table 1 d of the DBL values

  After the start of datalogging, I still just by adding the string values.  And if the size of the file the PDM goes beyond 1 GB, I create a new file and try again.  The application runs continuously for days/weeks, so I get a lot of TDMS files.

  It works very well.  But now I need to change my system to allow the acquisition of data for pause/resume.  In other words, there will be breaks in the signal (probably from 30 seconds to 10 minutes).  I had originally considered two values for each point of registration as a XY Chart (value & timestamp) data.  But I am opposed to this principal in because according to me, it fills your hard drive unnecessarily (twice us much disk footprint for the same data?).

  Also, I've never used a tiara, but I want to ensure that my data can be easily opened and analyzed using DIAdem.

  My question: are there some best practices for the storage of signals that break/break like that?  I would just start a new record with a new time of departure (To) and tiara somehow "bind" these signals... for example, I know that it is a continuation of the same signal.

  Of course, I should install Diadem and play with him.  But I thought I would ask the experts on best practices, first of all, as I have no knowledge of DIAdem.

  Hi josborne;

  Do you plan to create a new PDM file whenever the acquisition stops and starts, or you were missing fewer sections store multiple power the same TDMS file?  The best way to manage the shift of date / time is to store a waveform per channel per section of power and use the channel property who hails from waveform TDMS data - if you are wiring table of orange floating point or a waveform Brown to the TDMS Write.vi "wf_start_time".  Tiara 2011 has the ability to easily access the time offset when it is stored in this property of channel (assuming that it is stored as a date/time and not as a DBL or a string).  If you have only one section of power by PDM file, I would certainly also add a 'DateTime' property at the file level.  If you want to store several sections of power in a single file, PDM, I would recommend using a separate group for each section of power.  Make sure that you store the following properties of the string in the TDMS file if you want information to flow naturally to DIAdem:

  'wf_xname '.
  
  'wf_xunit_string '.
  
  'wf_start_time '.
  
  'wf_start_offset '.
  
  'wf_increment '.
