• VCA mode disabled / vmotion work?

  We have 2 groups of ESXi at our facility for vSphere, vSphere is version build 5.5U1, currently most recent available.

  Group 1 has Intel Xeon E7540 UC.

  Group 2 is brand new and uses recently published processors Intel Xeon E7-4860 v2.

  VCA is currently disabled on the two groups.

  Athe's systems are listed in the VMware compatibility guide for our latest version of vSphere.

  I expect this Setup to be able to live vMotion of virtual machines from the old to the new cluster without the use of CVS on either, but I assumed that the migration back to group 1 would require cluster 2 to affect the level of reference Intel EVC appropriate (Nehalem in this case).

  It turns out that I am able to migrate VM direct in both directions with no apparent problems (so far), with EVC mode disabled on both groups.

  Is an expected behavior or if ESXi/vCenter is somehow misreading? CPU compatibility (perhaps because the E7-4860v2 are a very recent model) or some other issue that could lead to problems with these migrations?

  This is normal unless you have turned to bike the VM on the new hosts.

  If a virtual machine has been powered - on on a former host and is migrated to the new cluster, it does not change the current features of the virtual machine CPU runlevel. He will continue to work with the old CPU features on the new host and is therefore able to migrate the old new host without problems, or additional AIDS such as CVS.

  However, if stop you now migrated virtual machine and power it on again on new hosts, the virtual material will apply the new host CPU capabilities (or the level of EVC of cluster, but you do not apply any) and you will not be able to migrate the computer virtual return to the armies of the former cluster.

• VCA mode - vm vmotion level lower than the level when turned on?

  Hi all, trying to get a definitive answer on this one there...

  Assuming that ESXi 5.1 u2, if you have two clusters, a set to VCA = Westmere and a game to Haswell, could you vmotion a powered on virtual machine cluster (Westmere) at a lower level to the upper level (Haswell) cluster, or must it be turned off?  I realize that, to take advantage of the latest processor have together, the virtual machine power cycle is required, but I didn't understand if you can vmotion it when turned on?

  Thank you! ~

  Yes, you can vMotion as a virtual computer to a host of generation more recent CPU very well provided that it contains of identical CPU instructions sets that older CPU's (the host has them enabled in BIOS too). You can vMotion that their return to guests because as long as you do not have virtual machines powered bike, they will continue to work with the old base EVC.

  I also vMotioned VMs hosts generation Nehalem to new hosts of Sandy Bridge earlier without problem.

• feature vMotion, vSphere Standard 4.0 and 4.1

  Dear forum,

  I would like to ask a simple question...

  A customer to lay mines on vMotion in vSphere Standard edition.

  How they get this vMotion functionality. They are currently serving vsphere 4.0 U1.

  They need to upgrade the engine first (4.0 U1 to 4.1)?

  Thank you...

  PS:

  vSphere 4.0 Standard, the vMotion feature edition is not available.

• Disable mode full screen in El Capitan?

  After much resistance, I have finally upgraded to El Capitan... Call me old school, but I'm not in love that when I maximize a window in El Capitan, which makes full-screen or that whenever I pass apps that I am treated to an iPhone like swipe animation. Despite a lot of research, I'm not finding a way to disable this behavior, so I thought I would ask the community if there is a way to disable the mode feature full screen in all areas or if I just need to restore my OS?

  You cannot change the behavior of Apple has changed for the Zoom button. I asked, they said, 'no '.

  You can hold down option by clicking on the green dot and it zooms, once again.

  You can also set the double click in title bar Zooms in system of Dock preferences.

  I'm not sure that understand the second part. You can disable the gestures of sweeping in the Trackpad System Prefs, but Cmd - Tab Switching is not slipping through the apps for me.

• Generation of data and acquisition of high frequency problem

  The fitting requires a fishing signal (32,764 KHz) saw tooth (0.3 Hz) signal output to drive the laser and acquires the signal from the output of the detector. I use the NI USB-6356 data acquisition with the speed limit of 1.25 MECH. / s.

  I put the generation mode like "Samples continues", samples of writing/reading of 1.2 M and 500K (Hz) frequency in the DAQ Assistant. I also tried 500K and 500K.

  The scheme of vi is illustrated in the following figure.

  

  Of the front plate, the generation of signal is normal, which may be seen in the left side of the following figure. But signals a lot of periodic fluctuations that will appear if the right side of the figure. In addition, the siganl acquist go all the time.

  

  I think it's maybe a few errors with my setting of the sampling frequency, I tried a lot of time for a change of pace, but it seems unnecessary.

  These fluctuations exist not only in the growing period but alos can be seen in the declining period, which is shown in the following figure:

  

  I tried to solve this problem for almost a week and try a lot of different rate, but all fail.

  Could someone give me any suggestions please? Thank you very much!!

  Thanks SOSOSO much for your reply immediately every time!

  This is my first time to write the Labview program with data acquisition

  The attachment is the field of Vi.

  I'll read the Web page that you offer, thank you very much once again!

• HP Pavilion g6 has a problem with the driver (s) interfering with Windows mode 'sleep'

  Hello all;

  I have a HP Pavilion g6 (about 4 years) gave me when my daughter bought a new. I had problems with it being slow to start and slow to close (a couple of times that it has initialized to me on the Web). I am running Windows 7 Home Premium 64 - bit SP1. Today, I ran a check on my system in advanced tools, I got this message: "Drivers interfere with Windows out of sleep mode" and this one: "a device driver for a device on your computer is cause of performance degradation. I checked the logs and he suggested I have uninstall these drivers, there are two listed, but they are the same driver. I don't know what to do here. Here are the details that were given:

  ID: 351

  Name: Several vendors AMD Miniport driver

  Publisher: Advanced Micro Devices, Inc.

  Feature: AMD M880G with ATI Mobility Radeon HD 4250

  Date reported: Monday, July 9, 2012 22:20

  Setting time: 1.9 seconds

  Next on the list is EXACTLY the same, except, reported Date: Thursday, June 20, 2013 22:32

  Setting time: 1.8 seconds

  The driver (s) is/is up-to-date. I'm so confused at this point. I think that I need this driver, but that does not mean I have two? Can someone enlighten me? These icons next to them warning, I would try to solve this problem before that I have to keep the PC doctor. Thanks to you all.

  Graphics card drivers are needed for the sleep mode feature. Based on the parameters of the driver, the availability of the mode 'sleep' is decided in Windows. Try reinstalling the drivers, then check: uninstall the drivers, reboot the PC, install the drivers, reboot the PC and then check. If this also fails to solve the problem, try to use a lower version of the drivers, by uninstalling the current version of drivers, restart the PC, install the lower version drivers, reboot the PC and then check.

  Please note that the beta versions are not stable, test rlease only. Beta version of the drivers will always have the latest version, but it's not recommended to use the drivers because it is still in development/testing.

• Add new ID/Primary Key column with custom ID generation

  I use Hibernate as ORM to interact with Oracle.

  This issue is no longer on the side of SQL to emulate the generator ID seqHiLo

  that we use to generate the primary key for tables, the column ID i.e.

  Now I want to add a new column to the ID of an already created table, and this table has data.

  I have a procedure to add the ID column in a table:

  For example:

  ALTER table TableName add (columnName NUMBER);

  Then create the sequence

  CREATE SEQUENCE SEQ_ID

  START WITH 1

  INCREMENT BY 1

  MAXVALUE 99999999

  MINVALUE 1

  NOCYCLE;

  and after that he use the UPDATE statement to insert some values into the column like this

  UPDATE tableName SET columnName is seq_test_id. NEXTVAL

  Here I intend to use hibernate_sequence, to be in harmony with the hibernation of generation mode the ID's

  The question is:

  UPDATE tableName SET columnName = hibernate_sequence. NEXTVAL, generates the ID in the order.

  However, I need identifiers according to the algorithm of seqHiLo.

  Is there a way to do this in pure SQL?

  In short, can we have a personalized way to generate IDS to use in the new column, rather than a sequential,

  as stated above?

  If you update every row of a session, it won't make any difference if you select from a sequence and use this value immediately (as in your example) or if you go through the algorithm of HiLo: be it you will end up with sequentially numbered lines without leaving space. Then after the update block of existing lines, you will need to create the sequence to be used by your Hibernate application with an initial value of your current value divided by the low value.

  If you really want to implement the algorithm of HiLo for the bulk loading, you can of course do so. But it is not necessary: the effect will be the same.

• Mulitple-NIC vs. CASL for VMotion

  Hello

  TNX for reading

  I use Vsphere 6

  My Switch have Nexus (2Port 10Gbs for Vmotion)! and I don't know which one is better!

  Mulitple-NIC or CASL (LAG and Active Mode) for VMotion?

  and another Q is for an optimal speed to migrate Vmition. better MTU (Jumbo frames).

  tnxxxxxxxxxxxx

  It's actually the answer to your question "Mulitple-NIC or CASL (LAG and Active Mode) for VMotion?", i.e. to use Multi-NIC vMotion rather than LACP.

• Using enhaced vMotion with ESX4.1

  Hello

  I was wondering if it is possible to use the new improved features vMotion (migrate virtual machines without shared storage) with just the upgrade 5.1 vCenter.

  I have an environment where I have a vCenter 4.1 virtual and multiple ESX 4.1 classics that are not connected to a shared storage.

  To update the environment 5.1 I need a downtime of the virtual machines since I stop them, move them to another server, reinstall the ESX and ESXi 5.1.

  My question is, can I update the vCenter 5.1, the enhanced vMotion allows to move virtual machines from one ESX to another or I must have reinforced version 5.1 on the Hypersivor as well as for vMotion to work?

  Thanks in advance.

  Hello

  Don't know if I'm clear with your query

  "I didn't want to VCA feature, but the new feature of 5.1 through the VMs of unshared data warehouses and hosts without any downtime.

  This feature implemented in vCenter or is it tied host? »

  Rule of thumb: VC should always be equal to or greater than the version of esx/esxi

  To make use of the functionality of Migration without shared storage, we have need of ESX and VC in version 5.1.

• Maintenance Mode settings

  Hello

  quick question - if Update Manager attempts to a host address and there is a virtual machine on the host connected to a physical scsi device on the host (eg. a tape drive) the host will not be able to enter in service mode using vmotion to move the virtual machine to another host. If there are other virtual machines on this host which can be moved to other hosts using vmotion, they automatically migrates the vm remaining with the physical scsi connection be suspeneded (if this option is chosen as the failure of maintenance mode response)?

  Thank you

  Steve

  the only way that a task remidiation will inaugurate an automated DRS event is if you have a fully automated value DRS.  If this is the case, all the guests who can vMotion.  The other must be powered off or suspended.

• No import Windows XP Mode VM-option in the file menu?

  Hello

  in this forum I read that there should be an "import Windows XP Mode VM" - option in the file menu if the Windows XP Mode is installed.

  But I installed XP Mode W AFTER VMw Player. Later, I tried a repair of VMw Player and later a de - and reinstall to see if the option appeared then - but no.

  Does anyone have a suggestion on how to get the option to appear - or should I just create a virtual machine from a XP pro CD?

  Host system is a Windows 7 pro with no hw virt

  Thank you in advance!

  Concerning

  Holst

  I found the problem. You must install the Windows XP Mode feature in Windows 7 to option to appear.

• vCenter Trial - add free ESXi existing Datacenter

  I've been running three hosts with the free version of ESXi. We try to evaluate licenses paid to get additional features (vMotion, etc.). I imported the virtual appliance for the server vCenter without any problem. Now I try to add my existing hosts in the data center, which I created in vCenter. When I do this, I get an error "download the file 10.161.30.3 to vCenter License Server failed because the exception: vim.fault.HostConnectFault". Is it not possible to add existing free ESXi hosts to vCenter trial?

  Cannot add ESXi hosts permitted by the hypervisor free license to vCenter Server. If the hosts 60-day evaluation period have not been achieved, we can use it in trial mode. Apart from this you can ask for the keys to the assessment of your VMware reseller representative.

• VCA - Westmere Vs Sandybridge

  Does anyone know if there is a case to daydream using EVC combining a Sandybridge cluster (new HP BLC460 G8s) with the slightly older G7s who use the Westmere? I have

  would not have to use EVC and loose some of the features on the new chipsets, but that said, Im not totally aware if there is a conflict and we use EVC, how much it affects performance.

  
  Thank you

  You need to use CVS for migration between Westmere and Sandy Bridge CPUs. See http://kb.vmware.com/kb/1003212 for a list of changes:

  Intel 'Sandy Bridge' generation

  Applies the basic features of the processors of the generation game 'Sandy Bridge' Intel® to all hosts in the cluster.  Compared to the Intel 'Westmere' generation mode, this EVC mode exposes additional CPU including AVX and XSAVE features.

  Note: Intel 'Sandy Bridge' processors that do not support AESNI and PCLMULQDQ is not admitted to the EVC modes higher than the generation mode 'Nehalem' Intel®.

  If you will not be able to benefit of AVX and XSAVE instructions games.

  It all comes down to a compromise, you should consider: If you want the flexibility to mix of clusters/migrate virtual machines between hosts of different generations of CPU, select CVS by using the lowest common denominator, which in this case is Westmere.

  The question you ask yourself now is how refraining from some new instructions results in the loss of real world performance, and this question is impossible to answer. There are some very specific as things AES-NI (already included in Westmere) which could bring you significant gains in some synthetic benchmarks. But unless you can identify and assess whether your applications really enjoy them, and you might as well an of to get your answer.

  At least, you can be sure, that he should not be worse than your current Westmeres, assuming that the #core frequency and similar caches. Given the optimizations internal, transparent in the architechture of CPU, it should even be faster out of the box.

  So much for today's software behave as processors of today are still basically " 386 overclocked at their base.

  I think I would sacrifice some obscure new CPU instruction on the flexibility gained any day. Unless I could really benefit from these new guidelines, or it didn't need as much flexibility. In my opinion, the last really significant change side of Intel which warranted a sacrificing exceptionally high flexibility, has been the introduction of Intel's Nehalem architecture. More than 3 years ago.
