Change resources for VMS FT

I admit, I haven't done much research on FT yet, so this may be a RTFM response...

I understand that FT works in a HA cluster, you set a specific VM to run FT and it creates a synchronization would clone on another host in the cluster it can switch on (not sure if the timing is correct?) milliseconds.  In this case it is a primary/slave relationship?  If so, the question I have is if you want to get the main host of change resource settings (i.e. increase memory), the slave will take over when you change these settings?  If the slave back, what happens when you turn back on the primary with the new resource settings?  The slave takes over as principal when get you to the bottom of the original virtual machine?  If so it swap back roles after she knows the original VM is back online?  If so they will see the new changes?

As I said, the primary and backup VMs are still the same. You cannot modify the primary virtual machine settings

(including the size of the memory) without affecting the secondary image. When you have stopped the primary for the parameters

change, the secondary will be also stopped automatically. The two do not work independently. They are always

in sync - perform exactly the same instructions, see exactly the same State of memory, etc. You can think

as a single system image - all operations of maintenance on the primary (parameter changes, patch installs)

spread to secondary education.

In short, you cannot use FT to protect any configuration changes that require a stop the virtual machine.

  • Rules for VMS oversized and too small

    When I change a strategy and look at the page "bulky or VMs undersized", I am surprised about the 1%, value for "is more than 1% for the whole range."

    How to read this? The way I read it now is: when you use the default settings, this means that when a virtual computer uses less than 30% CPU for a period of 1% of the time (= 1% 30 days = 7.2hrs), he has too many resources. Me 7.2hrs is very low, in fact I would be rather calm the resources of virtual machines when it is less than 30% to 90% of the time.

    How do you work with these values? You mostly use the default values for the default policy or adjust?

    Gabrié

    Hi g, I tried to get an answer to why the default value for most models of policy is 1% - but really you need to assign that everything that makes sense for your environment.

    For example, you may not care as much about the production system being oversized jack so that up to 90% (or even 100% if you want to just ignore oversized all together).  For non-produits you can be more careful, so maybe 30% or less, using your ranges.

    I always recommend to check the recommendations oversized against a metric graph of 30 days to use CPU or memory validate the pic and the duration before changing assignment of VMs.

  • is this setting for VMs cpu limitation cause performance hit for ESX server?

    We had recently come vmware consultant do a health check.  One of the things he mentioned briefly that we should change is that we should remove the limitations of cpu that we fixed for VMS.  His reasoning is that it causes needless overhead on the ESX servers.

    I was wondering what were the thoughts of everyone on this, I thought that the limitation of the cpu was a good thing because he stopped to a virtual machine in addition to cpu utilization... All opinions are appreciated.

    I agree with shishir08 here, the limits should be carefully thoughtover and only be implemented for specific vm:s.

    Why limit a machine if there are resources available for this purpose to consume?

    However, I think that the actions and reservations always should be applied.

  • 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;

  • Battle of pool of resources for production

    So the company I'm with now uses VMware test and dev for the

    last year. They had a small number of machines dedicated to a particular

    App on two production areas, but nothing else has mixed with these comments

    servers. The company has opted for the purchase of three Dell R900 (proc s fully

    populated) and 64 GB of RAM in each. Here are the companies licensed.

    Here's my dilemma. My boss has heard of resource pools and has some

    know how they work. But he heard other companies completely

    sabotage their production environment (no doubt to configure) resource

    pools. I worked with ESX for the past three years and my experiences

    tells me to start at least with a resource of high, medium and low

    pool for our environment. The company plans to put a great mix of

    servers in production. Some require a lot of resources and some require

    little. Is there a material that I can use ammunition that will eventually

    convince my superiors that it's the right thing to do? I'm really a bit

    stuck right now with just shot back by saying management emails

    that it is a very bad idea to roll out production VMware without resource

    pools.

    Here's my dilemma. My boss heard on resource pools, and has some knowledge of their operation. But he heard other companies totally sabotage their production environment (probably to set up) with pools of resources. I have worked with ESX for the past three years and all my experience tells me we must start at least with a pool of high, medium and low resources for our environment.

    Opinions are like the feet, there are always 2.  No one will ever agree.  your boss 'heard' but has no experience.  YOU have the experience, then I'd go with this approach.  If he hired I YOU to do the job, then it should allow you to do.  Period.

    Resource pools are also an option, but I use them mainly for management (assign permissions at the level of the pool and the Group VM by Department).  We manage the CPU / memory.

    They can also get you in trouble if you don't configure them correctly.  I agree, you should not just stick a bunch of VMS there without SOME level of control, rather means high medium or low, it is subjective.  These resources 'shares' only (unless you have reservations) will apply when the ESX host resources are low, then when everything is good, high medium or low, will not a difference.  They will all receive an equal share of the resource.

    Your boss must give up being a micro Manager.

  • Error of groups based on MAC "it has no resources for this range.

    Hello

    I have a SG300-52. My goal is a facility, where a client can connect to all ports and is automatically placed in a vlan are dependent on its MAC address.

    For this I put up some VLAN.

    Ports created by virtual local network name

    ---- ----------------- --------------------------- ----------------

    1 1 article gi1-46, gi48-52, Po1-8 D

    10 10 article gi1-46, gi48, gi51 S

    20 20 section gi1-46, gi48, gi51 S

    30 30 article gi1-46, gi48, gi51 S

    All ports where customers can connect the VLAN configured as unmarked.

    I have about 40 MACs, I want to put in the VLANs dynamically. So I've set up a group of Mac mapping vlan:

    conf t

    Serial section gi1-46

    switchport mode general

    switchport map General Mac-group vlan 5 5

    switchport map General Mac-group vlan 10 10

    switchport map General Mac-group vlan 20 20

    switchport map General Mac-group vlan 30 30

    Now, I want to add addresses MAC Mac-groups:

    mac 0000.0000.2222 Mac host card - group 10

    But after a few Mac added, I get an error "there are no resources for that interval.

    Is there a limitation on the number of MAC addresses in a group of Mac?

    Please advice how to proceed or if there is another way to achieve the goal.

    Tobias

    Hello Tobias,.

    There is a limitation on the number of MAC addresses could be added to the mac group and applied to interfaces. Each entry/MAC interface contains a single configurable AAGR resource (max allowed is around 500 I think). So, if you have addresses MAC 10 applied through 48 ports, it's 480 entries AAGR. This assumes you have no any other rule (ACL, MAC ACL etc.) configured. If you have a large number of MAC addresses that need assignment of VLAN static, the best approach would be to use the dot1x base assignment authentication vlan. It would be an evolutionary approach.

    I hope this helps.
