Regarding vSphere VCA and vMotion

• VCA and VMotion compatibility

  I am looking for a few new ESX boxes to expand our data center of VSphere 4 current U1.

  Ideally, I would buy Intel E7540 series servers because they can FT and adapt the specifications I need.

  I currently have a mix of X 5355 and E7330 ESX boxes.

  DELL sales tell me that E7540 processors are not compatible with the existing X 5355 vmotion and processors E7330 (even with active CVS).

  VCA and flexmigration enable me to vmotion (hot) between theses processors and processor E7540? I have the impression that the seller DELL is perhaps wrong as I thought VCA and flexmigration should mitigate the differences between these processors (obviously within reason)? Surely at least between the E7330 and the E7540?

  I had a look to many documents, including the KB Article: 1003212 but still trying to find a definitive answer?

  Forget DELL sales. They should be compatible under VCA VMotion (VCA's enhanced VMotion compatibility). But they are obviously not compatible FT.

• HA Cluster and vMotion CPU compatibility

  Will be the following servers and work of the processor all in a HA Cluster with ESXi embedded 4.1 with vCenter 4.1 vSphere?

  Reference Dell 2950 III Xeon E5410 @ 2.33 GHz

  Reference Dell R610 Xeon X 5550 @ 2.67 GHz

  Reference Dell R710 Xeon X 5650 @ 2.67 GHz

  Or will I have to activate the VCA Mode on the Cluster?

  Is there a chart that shows you what processor works in a HA Cluster and vMotion?

  You need a CPU mask on the VM vCenter migrating to the EVC cluster and adding one would require a reboot.  You can do instead.

  (1) create new cluster with appropriate VCA setting.

  (2) (2) migrer migrate virtual machines from one host, put it in maintenance mode and then move it to the new cluster.

  (3) stop vCenter.

  (4) connect to the host that was running with the vSphere client vCenter.  Unregister the virtual machine.

  (5) connect to the host in the new cluster, to save the VM vCenter and turn on.

• Port-groups, vSphere 5 and Jumbo (iSCSI) frames

  We will implement a UCS system with EMC iSCSI storage. Since this is my first time, I'm a little insecure in design, although I have acquired a lot of knowledge to read in this forum and meanders.

  We will use the 1000V.

  1. is it allowed to use only a GROUP of ports uplink with the following exchanges: mgmt, vmotion, iscsi, vm network, external network?

  My confusion here is what jumboframes? Should we not separate for this connection? In this design all executives are using jumboframes (or are this set by portgroup?)

  I read something about the use of the class of frames extended Service. Maybe it's the idea here.

  2. I read in a thread do not include mgmt and VMotion in the 1000V and put it on a vs. Is this correct?

  In this case, the design of uplink would be:

  1: Mgmt + vMotion (2 vNIC, VSS)

  2: iSCSi (2 vNIC, 1000v)

  3 data VM, external traffic (2 vNIC, 1000v)

  All network cards for parameter as active, Virtual port id teaming

  I have 2 follow-up questions:
  1. What is the reason I cannot use a 1000V uplink profile for the vMotion and management? Is it just for simplicity people do it that way? Or can I do it if I want? What do you do?
  [Robert] There is no reason.  Many customers run all their virtual networking on the 1000v.  This way they don't need vmware admins to manage virtual switches - keeps it all in the hands of the networking team where it belongs.  Management Port profiles should be set as "system vlans" to ensure access to manage your hosts is always forwarding.  With the 1000v you can also leverage CBWFQ which can auto-classify traffic types such as "Management", "Vmotion", "1000v Control", "IP Storage" etc.
  2. Shouldn't I use MTU size 9216?
  [Robert] UCS supports up to 9000 then assumed overhead.  Depending on the switch you'll want to set it at either 9000 or 9216 (whichever it supports).
  3. How do I do this step: "
  Ensure the switch north of the UCS Interconnects are marking the iSCSI target return traffic with the same CoS marking as UCS has configured for jumbo MTU.  You can use one of the other available classes on UCS for this - Bronze, Silver, Gold, Platinum."
  Does the Cisco switch also use the same terms "Bronze", Silver", "Gold" or "Platimum" for the classes? Should I configure the trunk with the same CoSes?
  [Robert] The Plat, Gold, Silver, Bronze are user friendly words used in UCS Classes of Service to represent a defineable CoS value between 0 to 7 (where 0 is the lowest value and 6 is  highest value). COS 7 is reserved for internal traffic. COS value "any"  equals to best effort.  Weight values range from 1 to 10. The bandwidth percentage can be  determined by adding the channel weights for all channels then divide  the channel weight you wish to calculate the percentage for by the sum  of all weights.
  Example.  You have UCS and an upstream N5K with your iSCSI target directly connected to an N5K interface. If your vNICs were assigne a QoS policy using "Silver" (which has a default CoS 2 value), then you would want to do the same upstream by a) configuring the N5K system MTU of 9216 and tag all traffic from the iSCSI Array target's interface with a CoS 2.  The specifics for configuring the switch are specific to the model and SW version.  N5K is different than N7K and different than IOS.  Configuring Jumbo frames and CoS marking is pretty well documented all over.
  Once UCS receives the traffic with the appropriate CoS marking it will honor the QoS and dump the traffic back into the Silver queue. This is the "best" way to configure it but I find most people just end up changing the "Best Effort" class to 9000 MTU for simplicity sake - which doesn't require any upstream tinkering with CoS marking.  Just have to enable Jumbo MTU support upstream.
  
  4. Concerning Nk1: Jason Nash has said to include vMotion in the System VLANs. You do not recommend this in previous threads. Why?
  [Robert] You have to understand what a system vlan is first.  I've tirelessly explained this on vaiours posts .  System VLANs allow an interface to always be forwarding.  You can't shut down a system vlan interface.  Also, when a VEM is reboot, a system vlan interface will be FWDing before the VEM attaches to the VSM to securely retrieve it's programming.  Think of the Chicken & Egg scenario.  You have to be able to FWD some traffic in order to reach the VSM in the first place - so we allow a very small subnet of interfaces to FWD before the VSM send the VEM's programming - Management, IP Storage and Control/Packet only.  All other non-system VLANs are rightfully BLKing until the VSM passes the VEM its policy.  This secures interfaces from sending traffic in the event any port profiles or policies have changed since last reboot or module insertion.  Now keeping all this in mind, can you tell me the instance where you've just reboot your ESX and need the VMotion interface fowarding traffic BEFORE communicating with the VSM?  If the VSM was not reachable (or both VSMs down) the VMs virtual interface would not even be able to be created on the receiving VEM.  Any virtual ports moved or created require VSM & VEM communication.  So no, the vMotion interface vlans do NOT need to be set as system VLANs.  There's also a max of 16 port profiles that can have system vlans defined, so why chew up one unnecessarily?
  5. Do I have to set spanning-tree commands and to enable global BPDU Filter/Guard on both the 1000V side and the uplink switch?
  [Robert] The VSM doesn't participate in STP so it will never send BPDU's.  However, since VMs can act like bridges & routers these days, we advise to add two commands to your upstream VEM uplinks - PortFast and BPDUFilter.  PortFast so the interface is FWD faster (since there's no STP on the VSM anyway) and BPDUFilter to ignore any received BPDU's from VMs.  I prefer to ignore them then using BPDU Gaurd - which will shutdown the interface if BPDU's are received.
  Thanks,
  Atle, Norway
  Edit:
  Do you have some recommendations on the weigting of the CoS?
  [Robert] I don't personally.  Others customer can chime in on their suggestions, but each environement is different.  VMotion is very bursty so I wouldn't set that too high.  IP storage is critical so I would bump that up a bit.  The rest is up to you.  See how it works, check your QoS & CoS verification commands to monitor and adjust your settings as required.
  E.g:
  IP storage: 35
  Vmotion: 35
  Vmdata: 30
  and I can then assign management VM-kernels to the Vmdata Cos.

• To work with a SAN and vMotion virtual servers configuration

  Hi all:

  I apologize in advance if this discussion is too much like another.

  I intend to use the following configuration (not yet deployed) and would appreciate your comments and input:

  2 physical host servers running VMware ESXi

  1 SAN Fiber Channel

  high availability and vMotion

  I just have a few questions:

  (1) then I keep all the VHD on the SAN files?  (I intend to have VHD files separate OS disk and DATA drive for each virtual computer).

  (2) is it recommended that I have all the hard drives the on host computers physical (to run virtual machines or anything else like swap files)?

  (3) how much space I have on the SAN?  I guess too much for the readers of the OS and DATA readers of all virtual machines... it's any additional space recommended for anything?

  (4) everyone would be able to direct me towards guides describing how to set up?

  Sincerely,

  Kahn

  (1) then I keep all the VHD on the SAN files?  (I intend to have VHD files separate OS disk and DATA drive for each virtual computer).

  Yes you can, and just a tip, on VMware world the virtual disk is called VMDK :-)

  (2) is it recommended that I have all the hard drives the on host computers physical (to run virtual machines or anything else like swap files)?

  You can use the same physical host computers without the hard drive, because you can boot from SAN, or use features such as automatic deployment, but it is the facility for the virtual machine, my recommendation is to use disks (volumes) of your San and share this volumes between your hosts to be able to configure High Availability (HA). Without shared storage, you can not HA.

  (3) how much space I have on the SAN?  I guess too much for the readers of the OS and DATA readers of all virtual machines... it's any additional space recommended for anything?

  Space on SAN depends on the size of your virtual machines and little extra space to make room for Exchange and snapshot files.

  (4) everyone would be able to direct me towards guides describing how to set up?

  The documentation will have everything you need: VSphere 6.0 Documentation Center , but if you want some guide step by step and with video/screen, see this one: BackToBasics | Mike Landry...

• Can we have different default gateway for MGMT and vMotion?

  Hello

  We run vSphere 5.1 update 3 Enterprise Edition. VLAN is implemented in our site recently.

  Network administrator assigns 3 VLAN to MGMT and vMotion VLAN10.  It also gives me different for these 2 DG VLAN (there is another local network VIRTUAL for VM).

  When I set up the IP address of vMotion, can I change to a different DG of the vSwitch MGMT?

  Thank you

  vSphere 5.1, no, you can't.

  vSphere 6, yes you can, here vmware now gave us separate stack TCP/IP for vMotion and contributes to the vCenter vMotion cross too.

• VSphere 5 and P2V

  Hi all

  I spent a few days trying to get answers regarding Vsphere 5.

  My company to buy the kit shortly and I have to impliment this weekend.

  One of the questions that I can't find here on the chatter or for millions of documents that are there:

  Vsphere 5 has its own converter: P2V?

  Or should I use the "VMware vCenter Converter Standalone 5.0?

  I install the version independent and done a conversion 'live '.

  but in the drop of choice on the place to settle, I saw no information for vsphere.

  I saw 'VMware Infrastructure Virtual machine' <-vsphere?

  so I created vmware server 2.0 and stored on a remote share.

  So to confirm, I essentially have to use the standalone version then?

  Yes!

  also if I buy the vsphere SDK 5.0, (for the 3 servers), makes or do not include vCenter? (don't know always what it is).

  The Essentials Kits as well as acceleration Kits include vCenter Server. It is just the converter that is not integrated in vCenter more.

• Possibility of setting up new vSphere 4 and pass the ESX 3.5 hosts?

  The upgrade path makes me nervous (am I too paranoid?).

  In any case, I have enough material and storage SAN to configure a new vSphere environment.

  Is it possible to install a new enviornemnt and separate vSphere 4 and then migrate the 3.5 environment hosts? The doc has always start with VC upgrade to version 4 and be careful not to break stuff...

  I actually finished a project a few days ago in this respect. I deleted the machine virtual old inventory, moved with the former VM of the LUN to the storage for the new environment group and added to the inventory again. Of course, if you do not use the same storage, it will be more in depth, but it certainly can be done. The plan was to do what weinstein said in his post, regarding the old host to the new Victoria Cross add, but I move the first LUN and had to finish like I did. It went well and I don't have problems with the virtual machine again.

• Change the subnet for VMkernel and Vmotion

  Our current configuration has Vmotion on the same subnet as our production machines, which I am not happy, encourage, that is causing our 3com troubled when past we vmotion virtual machine.

  We have dedicated a subnet of vmotion and want to change the port on the new subnet vmkernel.

  Our current vmkernel port has physical NIC 2, 1 in standby mode.

  My plan is to create another port vmkernel on the same switch and the standby card. I enable vmotion on that one, then disable vmotion on the original.

  Then, I would delete the original vmkernel port.

  This plan won't work and if so, what type of network on the age I will consider.

  Finally, is there a better way that I can do?

  Evening,

  It's actually how we run our Console Service with VMotion. We have the Service Console and VMotion on a vSwitch. The Port Console of Service Group is configured with 1 adapter active network and 1 in standby mode. The Group of ports VMotion is configured in reverse. It separates traffic while giving you still a level of redundancy in case a cable/adapter network breaks down.

  As you add VMotion for a vSwitch existing (vswif0), then will be without interruption, unless as it displays other says you have IP storage.

  Kind regards

• COS backup and VMotion networks

  I am trying to create an additional vswif to act as a backup to vswif0 used to COS and VMotion traffic.  Once the vswif has been added in place, if something happens to vswif0, as the cable car, traffic passes automatically to vswif1 or should I use the two vswifs at the same time?

  ________________________________

  Jason D. Langdon

  Hello

  No you will not get redundancy the way you describe. A second vSwif will not suddenly take over the primary vswif, routing automatically will not change. Redundancy is built into the vSwitch using grouping of NETWORK cards. You don't need 2 vSwifs, only 2 natachasery attached to the same vSwitch to the SC or to which he gives the portgroup SC.

• This virtual machine to become protected vsphere HA and HA can not try to restart after a power failure

  I got a 5.1 cluster with some problems HA.

  a few virtual machines are showing this

  This virtual machine to become protected vsphere HA and HA can not try to restart after a power failure.

  When I try to reconfigure HA on the host. It times out and fails.

  any idea?

  Instead of reconfiguring HA on the concerned host, have you tried to disable HA on the cluster and enable again? See: VMware KB: State of the virtual machine changes from protected to Unprotected

• VMware vSphere: optimize and [5.5] course is worth doing or not advice to scale

  Hi all

  Need some advice, as I am preparing to take the exam of the VCAP-DCA 5.5 in April.

  Will makes VMware vSphere: optimize and adapt training aid [5.5] or would be using the DCA official study guide book suffice?

  Just take peoples opinons, before I decide to spend money on the course.

  Thank you all very much.

  JIT

  Personally, I think that if you have below you don't take it out not before, then follow the course (unless you miss the VCP and the requirement of course)

  1 watch the video of Pluralsight VCP and VCAP

  2 buy the VCAP-DCA-5 study study guide bonus ebook on the VMware press - practical site reviews includes in the book

  3. go on the official and unofficial study guide CLI guide study

  4. do you have a host laboratory and practice and practice and make sure you only go on all the (MOST important) action plan.

  Enjoy autolab

  5. If you really need to take the course... you can do the lab connect version of the course which is $ 300 to $ 500.

  If the course if the company paid for the course, and he is not from your Pocket then of course the course.  But your hard-earned income is better spend in

  buy yourself gear lab, subscription VMUG and VMware books.

• vSphere replication and RDM

  Hello

  I have a site that I put in place which has Windows 2012 R2 invited with RDM in physical compatibility mode.  When I go through the wizard of replication vSphere for these servers I can configure replication for the comments and as expected I can not set up for the RDM (which is fine, I have those covered by the SRA) but on the last stage it errors with the following:

  Physical RDM mode is not supported by vSphere replication and there is a known issue, you cannot configure replication for VM with RDM physical mode even if you exclude this record of replication.

  Check the release notes: VMware vSphere replication 5.5.1 Release Notes

  Cannot configure a virtual machine with disc RDM in physical mode even if the disk is excluded from replication.

  If you configure a replication of a virtual machine with the physical mode, the following error message may appear:

  VRM Server generic error. Check the documentation for any troubleshooting information. The detailed exception is: HMS can not set disk UUID for disks of VM : MoRef: type = VirtualMachine, value = , serverGuid = null'.
  

  Workaround: No.

• Management and vMotion have the same IP address

  Being quite new to ESXi I have spent hours to deceive and reading and do not understand why my management and vMotion interfaces have the same IP.

  The configuration is the following:

  Cisco UCS blades

  8 cards per blade

  vmnic0 and 1 - management

  vmnic2 and 3 - vmotion

  vmnic4 and 5 - IP storage

  given the VM vmnic6 and 7-

  I installed and the management network has migrated to a DVS without issues.

  Now when I create the DVS/port group for vmotion and assign the IP address I met 2 problems as you can see in the screenshot attached the blade/network.

  Thanks for any info.

  P.S., Management and vMotion are on different networks.

  Yes, the ESXi host may have a default gateway. It is used only when a vmkernel must be routed traffic.

  In the case of vMotion - as long as your vMotion enabled vmkernels are all on the same subnet and VLAN, the default gateway will never serve.
