• Best practices for dealing with Exceptions on members of storage

  We recently encountered a problem where one of our DistributedCaches was closing himself and restart due to a RuntimeException is thrown from our code (see below). As usual, it's our own code and we have updated to not throw a RuntimeException in all circumstances.
  
  I would like to know if there are some best practices for Exception handling, other than catching Exceptions and their record. We should always catch the Exceptions and ensure that they do not spread back to code that is running from the pot of consistency? Is it possible to configure consistency so that our DistributedCaches are not completed even when filters custom and other throw RuntimeExceptions?
  
  
  Thank you, Aidan

  We have reproduced you problem in the House and it looks like a global filtering does not
  the correct thing (i.e. having caught a processed) when moving from a runtime exception.
  In general runtime exceptions should simply be exploited and returned to the application
  without compromising the cache server, so we will be solving it.

• Best practices of timing with Windows on ESXi4

  Is there a de facto standard for indication the configuration under Windows in a VMware environment? The traditional method of a synchronized domain controller against an external source and all other servers/clients internal synchronized on this domain controller the preferred method? Or is it better to keep the hosts synchronized to an external source with NTP and configure all the virtual machines to synchronize against the host with VMware Tools?

  What are your thoughts on that?

  If you have joined to a domain VMs, you wish that they stay in sync on your domain controllers and therefore would fail to sync via Vmware Tools.

  So:

  • ESX hosts and vCenter sync to an external source

  • synchronization of virtual domain to the host or the external source controllers

  • synchronization of vms that are joined to a domain to via the normal methods of Windows domain controllers

• Best practices in VMWare ESXi 3.5 installation and deployment of VMDK u3?

  Hi all

  I'm about to implement virtualization on my business technology

  I've got these resources to be used by VMWare ESXi 3.5

  Dell PowerEDGE 2950 III

  • 32 GB DDR - II 667 MHz

  • internal 4 x 500 GB SATA 7200 RPM HDD (RAID 5) - I know that it's slow to host the VMDK

  • Internal USB slot on the motherboard (but not USB flashdisk?)

  Dell PowerVault MD3000

  • 10 x 300 GB SAS 15 k RPM

  • 2 x Dual port Gigabit Ethernet NIC (x 4 in total)

  • iSCSI - 2 x Gigabit Ethernet for the switch (mute not to VLAN)

  I wonder where I should install the VMWare ESXi? for the VMDK, I believe that the deployment in the SAN is the right place.

  and any suggestion for the use of the SATA HARD drive internal?

  any comments would be greatly appreciated.

  Thank you.

  You mean Deployment.jpg diagram?

  In this case, there is an error.

  You need a network 2, not 4.

  Each controller and each NIC (on ESX) must have an IP in a net and another IP in the second NET.

  ESX guests 4 targets, 2 in a net, 2 in the other.

• Work with several sequences-best practices

  Hello.

  I ve just started using Adobe Premiere CS6. My goal is to create a long movie, which is based on 30 hours of footage in raw gopro recorded on a recent trip of 2 hours.

  Now my question is, what is the best practice for working with many sequences/clips?

  You have a single file of heavy project, with all the clips?

  Or make you small chapters that contains number of sequences x/x minutes long and ultimately combine all these?

  Or how would you do it the best way, so its easier to work with?

  Thanks a lot for your help.

  Kind regards

  Lars

  I make a primary sequence in your project and then modify the individual scenes in the form of separate sequences, and then nest them in the primary sequence.

  That way, you would have a single file of project heavy with all the media files (raw video, music, etc.).

  I find it easier to work with. With the help of several project files would get too complex and fragmented throughout the of your computer.

  I work with a lot of video GoPro, so I wonder what your Setup looks like. What device you have, and how your computer/Premiere Pro is configured?

• NetApp Best Practice and independent labels

  Hi, Best practices for VMware NetApp recommends, transitional and temporary data such as comments

  pagefile operating system, temporary files and swap files, must be moved to another disk virtual one

  different data store as snapshots of this type of data can consume a large amount of storage in a very short time

  
  
  

  high time due to the rate of change (that is, to create a data store dedicated to transitional and temporary for all VMS data without other types of data or VMDK residing on it).

  NetApp recommends also configure the VMDK residing in these stores data as "Independent persistent" disks in vCenter. Once configured, the transitional and temporary data VMDK will be excluded from the VMware vCenter snapshot and copy snapshot of NetApp initiated by SnapManager for Virtual Infrastructure.

  I would like to understand the impact of this best practice - can anyone advise on the following:

  • If the above is implemented:
    
    
    • Snapshots will work via vcenter?
      
      
    • Snapshots will work via the Netapp Snapmanager tool?
      
      
    • The snapsot includes all of VM disks? If this is not the case, what is the consequence of not having the whole picture of the VM?
      
      
    • The snapshot of vcenter can restore ok?
      
      
    • Netapp snapshot can restore ok?
      
      
  • What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology?
    
    

  Thank you

  
  
  
  
  
  

  Hi Joe

  These recommendations is purely to save storage space when the replication or backup.

  For example, you can move your *.vswap (VM swap file) file to a different data store. NetBackup can do instant IVMS of the warehouses of data and with this configuration, you can exclude this particular data store

  This is also true if you create a data store dedicated for OS Swap files, mark independent so that vCenter not relieve these VMDK.

  I did a project with NetApp on boxes of SAP production

  We moved all the files in *.vswap to warehouses of data created and dedicated RDM for the OS Swap locations

  We actually used the SnapDrive one NetApp technology to suspend the DB SQL on the ROW before the ROW is broken, but I won't go into too much detail

  To answer your questions (see the comments in the quote)

  • If the above is implemented:

    • The snapsot includes all of VM disks? If this is not the case, what is the consequence of not having the whole picture of the VM? -No. - *.vswap file is created when the VM is started (no need to backup)

  -OS Swap VMDK of location must be re-created in the case of restoration. WIndows will be

  always Prime if the Swap disk is missing, and you specify the new location of swap.

  • What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology? -These backup products use vCenter snapshots and because the vCenter snapshots works 100% it shouldn't be a problem.

• 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.

• / var/log is full. Best practices?

  One of the score of the newspaper of our host is 100% full. I'm not the practice administrator for this host, but manage/deploy the virtual machines it for others to use.

  I was wondering what's the best practice to deal with a more complete log partition? I found an article that mentioned editing the file /etc/logrotate.d/vmkernel/ so that files

  be compressed more often and saved for less often, but there was no real clear instructions on what to change and how.

  Is the only way to investigate on the console itself or the directory/var/log via putty? No there is no way to see VIC?

  Thank you

  Hello

  To solve the immediate problem, I would transfer to any newspaper in/var/log with a number at the end is dire.1,.2, etc. to a temporary storage outside the ESX host location. You could run something similar to the following command of the scp to do:

  scp /var/log/*.[0-9]* /var/log/*/*.[0-9]* host:TemporaryDir
  

  Or you can use winscp to transfer of the ESX host in a windows box. A you get the files from existing logs from the system for later playback, use the following to clear the space:

  cd /var/log; rm *.[0-9]* */*.[0-9]*
  

  I would therefore consist logrotation thus directed by hardening for VMware ESX.

• Implementation of best practices

  We have a budget tight but would like to be considered for implementation, as many best practices of VMware as possible. We realize that, with our budget, we will not be able to implement many of them but I would like to get the most, most critics made. What do you consider the ABSOLUTE MUST have best practices to an environment that includes the following:

  6 hosts ESX3.5 and 1 VC2.5 with the license server Center. Each host has 6 physical network interface cards. We have licenses for vMotion, DRS, and HA. Our current setup is:

  vSwitch0 is home to a group of virtual computer and Console of Service ports with 2 network cards

  vSwitch1 is home port for VM group

  vSwitch3 is home to port VM group

  vSwitch4 is a dedicated vMotion network

  Physically, our hosts are connected to a single physical Nortel SwitchStack affected ports to the VLAN

  We have our virtual machines on different subnets 3

  This infrastructure is inside our firewall. We have a demilitarized zone, but it is not virtual.

  Looking for candid suggestions.

  The vSwitch is an object that exists in the memory of an ESX server.  Therefore, the exchanges on this vSwitch belong within this memory object.  This vSwitch keeps his stats, the mac entity table.  With the help of a 2nd vSwitch creates a 2nd object that does not interact/interface with the first.  Then, it adds another layer of separation between the information.  Gaps are a good thing for this reason.

• 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.
