  Hello.

  I was looking at the solution of vmware fault tolerance and have I have a question:

  You can store the primary and secondary VMs on databases of dirffent? If you can, provide this storage redundancy as well?

• SAN multisite and VMware Fault Tolerance

  Hello

  My apologies if this is in the wrong section.

  I have a requirement for the two main rooms, with SAN and ESX hosts in each room.

  In total I have, for the sake of arguments, 200 VMS, with a split 50-50, so 100 in each room Basic.

  I want to use VMware of fault tolerance for machines remain operational in the event of a major failure or the other room Basic.

  I think I can use Multisite SAN to do.

  Please see attached diagram fo what I want to do, I know that the diagram is not correct but I drew it fast just to try to explain the scenario.

  What I want to know (or have help on) is:

  Is it possible to use fault tolerance in this way have no downtime in the result of a failure of basic room? (basic rooms are not very remote and use the same networks)

  How does multi-site SAN work, are there articles I can read to help me understand this?

  Multisite perhaps SAN iSCSI or fibrechannel?

  Thank you.

  SAN should resemble a single San for all ESXes. It doesn't matter how you do it.

  > If I my synchronous SAN mirror, might simply use FT for the vcenter as well?

  It is possible for the small environment. In general, vCenter requires 2 vCPU, while FT works for uniprocessor VMs only. But do not overestimate FT, it is not a universal solution and the universal answer.

  > Also with FT, can you specify the server host in the cluster to act as the secondary?

  Directly - no. The only way - to create link VM to any resource that is available for 2 ESXes only.

• SAN replication for fault tolerance

  Hello world

  I hope that someone could point me in the right direction - it seems that I do not have enough review in the subject and the deadlines are too tight for me to explore different scenarios in depth...

  We have two data centers a few miles of each other connected by 100 Mbps link. Each datacenter will have 5 blades BL490 with ESX Standard accommodation about 50 VMs. ABC message a HP eva4400 SAN with SAN replication implemented. VC will be the first data center and the two data center are networked.

  SAN replication is block-level, so it seems that I can not just replicate changes, but all entries will have to be replicated. This should not be a problem because the link can support about 1.8 TB a jouret of data can be buffered.

  I am not however a vision how recovery would work in this case. We don't need instant recovery, I would say that 4 hours of recovery time is accepted if SRM fancy Automatic as DR scenario would not easily be accepted financial reasons, but your comments are welcome.

  Current idea is the following: replicate LUNS of primary site to the secondary. When disaster strikes, personal COMPUTER turns on the ESX host on the remote side and connects replicated LUNS, and then registered VMs and change my IP address.

  I understand that this seems horribly manual process and I'm pretty sure I missed some obvious pitfalls here.

  Could someone let me know which direction should I go? An article on the subject?

  This is a new installation and we prefer to put in place the basic recovery process and resize it later. I just need to have a good direction to allow this scalability.

  I thank very you much in advance!

  I think you have a good understanding of how it should work it is something I would like to implement, but use Veeam as support for replication. Here's what I would do for the IP addresses of the virtual machine. I like to keep the same IP addresses because I know that not every simple VM uses DNS for all of its applications, databases, etc. So unless you are POSITIVE you covered all the basics of your DNS, I'll try to use the same IP addresses. You just work on the part of this routing before start you your virtual machines. So make sure that when switch you or test your virtual machine failover, you make sure that if you have a virtual machine with the IP 10.10.10.10 with two Datacenters A & B, the routing would ensure that all your customers cannot talk to the datacenter B until you do this active way. In this way, you can test your failover

• Deployment of Exchange Server 2013 on VMware Fault Tolerance

  Hi people,

  Instead of using the DAG have on the Exchange Server 2013, which is warnings for the stand-alone Exchange 2013 Server deployment and then implementation of the Vmware FT or at least HA to the availability at the hypervisor level?

  With HA no problem - with FT under vSphere 5.1, you are limited to a single vCPU VM-

• Little doubt about VMware Fault Tolerance

  I would like to know, in case if the Virtual Machine goes down or get corrupted, the setting of Virtual Machine replica on the secondary host is going live?

  Else FT is applicable only when the broken material / host, please provide details?

  Both machines use the same storage and the second machine is basically running the same instructions as the first. If the first has been tampered on disk or a memory error, it appears in the second. FT is realtime protection against hardware failures.

• Windows for the issue of fault tolerance

  I counted on 4 virtual machines running in a fault-tolerant environment.

  I'm reading that I should get 2, Windows server 2008 R2 Ent. licenses because they are counted as separate servers (even if they are just redundent).

  Is this true?

  Do you mean 4 virtual machines protected with VMware Fault tolerance (FT) or using HA to protect an ESXi host failure?

  Windows Enterprise gets you 4 total licenses for virtual machines but it is authorized by the ESXi host. So if you have two hosts of ESXi, you would need two copies of Windows Enterprise to protect the 4. VMs data center total is something much better, if you plan to have more than 4 VMs.

• "Support clustering features such as fault tolerance" option greyed out (unavailable)

  Hello

  For a customer, we try to simulate a SQL using MSCS failover.

  I found a lot of information on the configuration, using only the virtual machines.

  However, for some reason, we cannot select the option 'support clustering features such as fault tolerance', when trying to create the quorum disk in Vsphere.  (See the image)

  We have deployed 1 DC (W2K3 - x 86) and 2 servers SQL 2005 on a W2k3 x 64 environment.

  We use Vsphere 4.0 and ESX 3.5

  I am relatively new to this configuration and I couldn't find any document appropriate, pointing in the right direction.

  Thanks in advance.

  Armand

  Looking again at your attachment, the processor is on the list supported for FT, but upgrade to / with ESX 4 is also a requirement.

  Its interesting to look at the limits of the feet as well. The big one for us, it's that it currently works only on Virtual Machines with 1 vCPU and no more.

  Good luck!

• Cannot access the fault tolerance Mode

  Dear all,

  I have a problem, which allows VMware ft. I have 2 IBM eServer HS12 blade with IntelCore 2 Duo E6305 CPU @ 1.86 GHz

  When I turn on the machine virtual of FT it gives the following error.

  Recording/playback is supported for VMS 64-bit only on some processors. Abandonment of record/replay. Unable to access the mode for fault tolerance.

  Are there settings that I need to do on the host VMware ESX or VM.

  Kind regards

  Rahiz

  Rahiz,

  According to the Knowledge Base the CPU is not supported for the fault tolerance

  .

  Take a look at the Article KB 1008027 - processors and operating systems that support VMware Fault Tolerance

• API to enable Fault Tolerance

  My BR request, I have to turn off FT in order to take a snapshot of the virtual machine. I found API TurnOffFaultToleranceForVM_Task to disable FT for a virtual machine. But I see no API to turn back on again. Why is there not an API to turn FT.? Is it possible that I can do this?

  Thank you

  Parag

  For the management of fault tolerance, you will use the following methods:

  CreateSecondaryVM_Task() (for a virtual machine to configure FT)

  EnableSecondaryVM_Task() (turn ON FT for a virtual machine)

  DisableSecondaryVM_Task() (disable FT for a virtual machine)

  TurnOffFaultToleranceForVM_Task() (turn OFF FT for a virtual machine)

  You can take a look at this script that I wrote to manage the IP: ftCLI.pl - VMware Fault Tolerant Managment

• Protect both virtual machines with features of ESXI fault tolerant clustered disk

  Hello world

  I read the following:

  VMware vSphere with operations management: fault tolerance | United States

  The line that interests me is:

  "VMware vSphere® fault tolerance (FT) ensures the continued availability of the applications in the event of server failure by creating an instance of live snapshots of a virtual machine that is always up to date with the first virtual machine. In the event of hardware failure, vSphere FT triggers automatically failover - ensure no interruption of service and prevent data loss. »

  Question:

  FT can protect both virtual machines that share disks in a cluster configuration? (A cluster SQL instance for example)

  FT can protect both virtual machines that share disks in a cluster configuration? (A cluster SQL instance for example)

  No, you can't, because there is an incompatibility with FT.

  Refer to the documentation for all requirements and interoperability: interoperability of fault tolerance

• Local storage is a viable option with VMware?

  At this point, I have concluded the following: 1) good shared storage is very expensive compared to good local storage. (2) good shared storage is much more subject to complex failures as local storage. Because live storage migration exists, I think I'll empty the shared storage to reduce complexity, increase availability and * performance *.  I've added emphasis to the latter, because my anecdotal experience has not been good to achieve this: my MegaRAID cards that perform very well under linux regularly perform like absolute garbage under ESXi 5.x. Can someone help me out here?  Is there a good RAID card which allow the performance of local data store in ESXi?  LSI cards are cursed?  I have to sacrifice a goat or a kind of singing and dancing for the gods of EMC? Because of the HUGE General fresh price on the shared storage, I intend on executing all SSD (the new Samsung 850 s will be 150TBW, which is great for my purposes) for the local data store. Any guidance would be appreciated.

  For posterity, the solution was to create a San with Windows Server 2012 and export "Storage space" on iSCSI.  It is a very affordable way to serve the high performance shared storage because they make the SSD caching. At this point, we will probably go through Hyper-V, since VMware offers no compelling storage solutions (I understand no - EMC holds a majority - no need to explain).
