• Best practices of ESXi.

  I'm trying to find out if I implement best practices correctly on ESXi 4.1 U1. Our facility has two on-board NICs and a quad card NETWORK to use for data and management networks. We have fiber for the side storage. If I understand the latest practices should I trunk 6-port then use port groups to manage traffic VLAN where going.

  My question is this does not put excessive pressure on the network card that is used for the traffic of vmotion/vmkernel? If I put the switchport in one VLAN specific datagrams wouldn't get inspected and abandoned by the switch asics as opposed to the ESXi host to have to deal with them? I don't know if traffic would have a significant impact, so be it, but wanted to check before the implementation...

  Thank you

  I guess that you are concerned about air on the ESXi host performance, because it must deal with VLAN tags.

  Don't worry about this. The overhead is minimal and modern NICS also have material unloading of functions for VLAN that will be used by ESX in many cases of handling.

  However, remember that you have no safe the uplinks on the physical switch! Just create a virtual switch and add all the rising physical their. ESXi them then use all function of the active/standby/unused attribute that you can set by group of virtual ports.

• Best practices of ESXi 4.1 installation

  Since esxi a sc removed no matter if I create different data stores, one for vkernel and another for virtual machines?

  Also for networking is important to create the management network on the separate vswitch from VM network?

  What is best practice?

  traffic will pass by vmkernel and distributed. environment like yours, that separates the vmkernel makes no difference because there isn't any iscsi or vmotion traffic.

• Best practices for ESXi system saves location

  Hi all

  What is the recommendation of VMWare for the storage location of the ESXi logs? Of course, if a VMFS path is not configured under software > advanced settings, then the papers will not be stored on a persistent storage. We have installed 5.5 ESXi hypervisor on a 16 GB USB, newspapers can be stored there?

  Thank you!

  You must configure partitions on the USB key, which is a bit complicated. One for ESXi and the other for logging. If the host has local storage (our not, that is why we are doing the extra work) it may be better to just write logs in the data store.

• Best Practice network for 6 uplinks

  Can someone help me and tell me recommended for segregation with 6 uplinks. Ideally, I would like to have 2 management, 2 VMotion, 2 for Production and 2 for iSCSI (software). However I have only 6 natachasery. Recommend that people would be here when you use HA and DRS clusters?

  I would also use the iSCSI team balancing, but do not know how to set up. The SAN has two NETWORK adapters and is trucked by using 802.1ad. How to configure the load balancing across the vSwitch iSCSI to take advantage of the trunk to the SAN?

  Any help or pointers to good white papers or documentation would be really appreciated.

  Thank you

  Tony

  Hello

  I would use:

  Load Balancing: route based on the Port ID of source

  Network failover detection: State of the link only

  Notify the switches: Yes

  BACKSPACE: Yes

  Of course, it's just my opinion that's all that's right for you. You can use the probe if you want a constant pulse of your links.

• Best practices for vsphere 5.1

  where can I find the doc more up-to-date about berries EQL configuration / best practices with vmware vsphere 5.1

  Hello

  Here is a link to a PDF file that covers best practices for ESXi and EQL.

  Best EqualLogic practices ESX

  en.Community.Dell.com/.../20434601.aspx

  This doc mentions specifically that the storage Heartbeat VMKernel port is no longer necessary with ESXi v5.1.  VMware has corrected the problem that made it necessary.

  If you add it to a 5.1 system it will not hurt.  It will take an IP address for each node.

  If you upgrade 5.0 to 5.1, you can delete it later.

  Here is a link to VMware which addresses this issue and has links to other Dell documents which confirm also that it is fixed in 5.1.

• New to ESXi ESXi installation USB or local disks operation best practices?

  I'm new to Vmware and run a small store, what is the best practice or best method to install the OS ESXi.  I currently have a few that I have installed on the usb stick on the server Board.  After some research it would be better to have two small drives SSD that I can raid with the operating system, then another RAID for the VM data store.  USB is a single source of failure.

  Thank you

  Mike

  Hello

  Having the internal hard drives in RAID1 for the o/s will certainly to avoid a single point of failure, as you pointed out correctly. At present the death of your USB key, your host problems quite quickly, and you will need to get a new one and re-install again. You could save your good host configuration and realistically - it does take too long to rebuild a crowd if he dies. Lose other stuff like network configurations and others would however be a pain!

  I think I have two SSD internal drives in RAID1 for the o/s is probably overkill. You will have an advantage any speed of startup, but realistically most of the servers restart everything often and once that ESXi is in place and operational it is very little activity on the disks, a config updates every so often and so on. I'd be inclined to use a SSD to create a Cache of the host for the swap drive, like that you can actually use the SSD and get more performance for your money.

  Many manufacturers (like Dell) use internal SD cards in RAID1. While SD cards are not known to be very robust, because of the congestion of ESXi and the minimum number of necessary paperwork once installed initially, it makes a less expensive alternative to business class for the o/s disks.

  In regards to your data warehouses, having an internal RAID your local disks is best if you use a stand-alone host with no storage attached to the network. You always have the problem of failure of the host if.

  See you soon,.

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• The ESXi 4.1.0 to 6.0 upgrade. -upgarde and best practices

  Hi guys,.

  We are a small business with a single physical server, ESXi 4.1.0 installed with approx. 8 VMs. We plan on buying Essential Kit 6.0 ESXi because that's all we need right now. However, as VMWare says that 4.1.0 to 6.0 upgrade is NOT supported (matrices of the interoperability of products VMware), how we improve our host and VMS?

  I guess the correct way will be upgraded from 4.0. 5.5 U3 first, then to 6.0. However, if we buy the 6.0 license essential Kit, that we will be able to always download and install and upgrade of the host and all VMs to U3 5.5, and 6.0. Essentials?

  In addition, what are the best practices to upgrade a single host with multiple virtual machines? What I did research, we should back up important files from virtual machine, all critical data, etc. All recommendations are welcome. My understanding is that the upgrade also virtual machines will be upgraded automatically, that's correct - methods of upgrade to ESXi 5.5 (2058352) | VMware KB

  Best regards

  Hello

  As you said, you cannot upgrade host ESXi 4.x to 6.x, you must first upgrade 4.x to 5.x and then switch to 6.x

  Before moving to 5 or 6, make sure you ESXi host is compatible with ESXi 6.

  Check cheque and VMware hardware compatibility list if your server is listed.

  Although you'll have a 6 ESXi license kit, you can download ESXi 5.x and use it to upgrade process.

  Only if you need to use 5.x permanently, then you need to get your license keys downgraded to 5.x, otherwise once you upgrade host to 5.x, go ahead and level to ESXi 6.x

  Backup-

  Before you begin the upgrade, make sure that you have backup of all VMs critics.

  Either you can download/export all VMs as OVF, or you can use Veeam's free edition to make the backup of virtual machines

  -Update

  You can join the server ESXi ISO Installer and boot server form ISO and update.

  During the Installation process make sure to select ' PRESERVER VMFS and upgrade ESXi host '

  If you do not keep vmfs, all virtual machines will get deleted during the installation/upgrade process.

  Once you get ESXi Host upgrade to Upgrade VMFS 5.x version so that it can support 6.

  Then finally the ESXi host to 6.x upgrade, yet once make sure PRESERVE you VMFS during installation.

  If you have vCenter Update manager, use update reach the average upgrade easy it is to upgrade.

  Thank you

• Best practices for backup of vCenter device and ESXi hosts?

  Hello

  I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

  • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
  • It's recommended to backup the ESXi host or is it easier to any re - install failure?

  Best regards

  Hello

  You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

  I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

• Best practices for storing the Logs of the system for all newly improved ESXi hosts?

  Hi people,

  What are the options and best practices for the Logs of the system for all newly improved 5.1u1 ESXi hosts?

  Do I need to have the Syslog server or it can be safely ignored?

  Thank you

  Evening,

  Syslog is preferred, but VMware has provided a collector of syslog on the vcenter installation disc can be installed on any windows host or your vcenter. I can't count the number of times where I had guests CMTF or newspapers lost... Fortunately for the syslog which collects up to the accident.  It is not necessary, but it's really a good idea without any real cost since you can use your vcenter host.

  Here is an article on how to install it:
