Figure 1 — vSphere Editions features set Source: However, if cost is a pressing issue, the lesser of the vSphere Essential Kits is the least costly of them all. Both prices exclude support and subscription costs. Figure 2 — vSphere Essentials Kits license and support costs Source: It enables consolidation and management of applications to reduce hardware and operating costs—all with a low upfront investment.

Essentials must be purchased along with a one-year subscription to software patches and updates. Support is optional and available on a per-incident basis. Essentials Plus is ideal for small businesses that, in addition to hardware and operation cost savings, are looking for maximization of application availability and business continuity with a low upfront investment.

SnS for Essentials Plus is sold separately. A minimum of one year of SnS is required. Together with Essentials Plus, you also have to purchase a 1-year minimum of SnS support. The main issue with Essentials is one of scalability which can only be addressed by upgrading to one of the Acceleration Kits mentioned below.

Figure 3 — vSphere Essentials Kits feature set Source: They offer the same features as the Enterprise editions of vSphere but each is locked to a maximum of 3 ESXi hosts min. For an embedded deployment, disable SSLv3 in the server. For a deployment with an external Platform Services Controller, determine whether any legacy vCenter Server systems are connected, and upgrade those vCenter Server systems. Disable SSLv3. Open the server. Error when cloning an encrypted virtual machine with one or more unencrypted hard disks When you clone an encrypted virtual machine, the following error results if one or more of the hard disks of the virtual machine is not encrypted.

The operation is not supported on the object. The clone process fails. Even if you do not make changes to the advanced settings, the clone process succeeds. A specified parameter was not correct: Network becomes unavailable with full passthrough devices If a native ntg3 driver is used on a passthrough Broadcom Gigabit Ethernet Adapter, the network connection will become unavailable.

Run the ntg3 driver in legacy mode: Reboot the host. Use the tg3 vmklinux driver as the default driver, instead of the native ntg3 driver. Any work requests that are enqueued on the queue pairs are removed and not completed. At reboot, the legacy USB driver loads. Guest kernel applications receive unexpected completion entries for non-signaled fast-register work requests RDMA communication between two virtual machines that reside on a host with an active RDMA uplink sometimes triggers spurious completion entries in the guest kernel applications.

This can cause completion queue overflows in the kernel ULP. To avoid triggering extraneous completions, place on separate hosts the virtual machines that will use fast-register work requests. As a result, the virtual machine becomes inaccessible during a snapshot operation or migration, if at the same time the RDMA application is still running. The action is performed successfully, but the Netdump transfer is much faster with other NICs. As a result, the kernel modules fail to load.

The NIC is up with some delay. You must re-join Active Directory so that the system keytab is updated. Intel LM or I vmnic might encounter an unrecoverable hang A problem is triggered on Intel LM or I vmnic with heavy traffic, such as 4 pairs of virtual machines running netperf and repeatedly disabling and re-enabling VMKernel software emulation of hardware offload capability. With some cycles of disabling and re-enabling, the hardware runs into a hang state. If you encounter this hang you must reboot the host.

Intel i NIC might hang and lose networking connectivity The Intel i family NICs, displayed as "Intel Corporation Ethernet Connection ILM" sometimes with a "V" suffix , might experience a hardware hang state that can cause the system to lose networking connectivity on the port. This issue is triggered by disruptive operations while traffic is going through the NIC. For example, you might encounter this error if you bring down a link using the command esxcli network nic down vmnixX while copying a file over the i port.

This problem might also be triggered with heavy traffic, such as 4 pairs of virtual machines running netperf and repeatedly disabling and re-enabling VMKernel software emulation of hardware offload capability. The NIC is not functional until you reboot the host. Avoid using i NIC port in critical jobs. Avoid doing disruptive operations on i ports. Avoid disabling and re-enabling VMKernel software emulation of hardware offload capabilities on Intel I adapter.

No matter what configuration you set up on this end of the connection, it is not applied on the ESXi side. The auto-negotiate support causes a duplex mismatch issue if a physical switch is set manually to a full-duplex mode.

Perform either of the workarounds: On the physical switch port, set the speed and duplex mode to auto before an upgrade or fresh installation.

You can switch to the igb driver by running the commands: Use async driver. Perform these steps: Run the vmkfstools --growfs command on one of the hosts connected to the volume. Perform the rescan-vmfs operation on all host connected to the volume. VMFS6 datastore does not support combining n and e devices in the same datastore You can expand a VMFS6 datastore only with the devices of the same type. If the VMFS6 datastore is backed by a n device, expand the datastore with the n devices.

If the datastore is created on a e device, expand the datastore with e devices. ESXi does not support the automatic space reclamation on arrays with unmap granularity greater than 1 MB If the unmap granularity of the backing storage is greater than 1 MB, the unmap requests from the ESXi host are not processed. You can see the Unmap not supported message in the vmkernel.

Using storage rescan in environments with the large number of LUNs might cause unpredictable problems Storage rescan is an IO intensive operation.

If you run it while performing other datastore management operation, such as creating or extending a datastore, you might experience delays and other problems. Problems are likely to occur in environments with the large number of LUNs, up to , that are supported in the vSphere 6. Typically, storage rescans that your hosts periodically perform are sufficient.

You are not required to rescan storage when you perform the general datastore management tasks. Run storage rescans only when absolutely necessary, especially when your deployments include a large set of LUNs.

When this issue occurs, the vmwarning. Perform the following steps: Unmount the affected NFS 4. If no files are open when you unmount, this operation succeeds and the NFS 4.

You can then remount the datastores that were unmounted and resume normal operation. Keep the NICs disabled for as long as it is required for the server lease times to expire, and then bring the NICs back up. Normal operations should resume. If the preceding steps fail, reboot the ESXi host. As a result, any existing NFS 4. Wait for the lease time of 90 seconds to expire and manually remount the volume. Mounting the same NFS datastore with different labels might trigger failures when you attempt to mount another datastore later The problem occurs when you use the esxcli command to mount the same NFS datastore on different ESXi hosts.

If you use different labels, for example A and B, vCenter Server renames B to A, so that the datastore has consistent labels across the hosts. If you later attempt to mount a new datastore and use the B label, your ESXi host fails. This problem occurs only when you mount the NFS datastore with the esxcli command.

It does not affect mounting through the vSphere Web Client. When mounting the same NFS datastore with the esxcli commands, make sure to use consistent labels across the hosts.

An NFS 4. This issue occurs if the VNX server unexpectedly changes its major number. However, the NFS 4. Remove all datastores exported by the server and then remount them. Virtual Volumes Issues After upgrade from vSphere 6. Log out of the vSphere Web Client, and then log in again.

The vSphere Web Client fails to display information about the default profile of a Virtual Volumes datastore Typically, you can check information about the default profile associated with the Virtual Volumes datastore. However, the vSphere Web Client is unable to report the default profiles when their IDs, configured at the storage side, are not unique across all the datastores reported by the same Virtual Volumes provider.

This change affects any scripts that use hard-coded values for the name of the adapter. Because VMware does not guarantee that the adapter name remains the same across releases, you should not hard code the name in the scripts.

Buy and comparison VMware 6.5 versions Why upgrade to VMware vSphere 6.7 (or why not)

I hope this article helps us best suited for environments where there Buy and comparison VMware 6.5 versions workstation pro and VMware workstation vSphere ESXi hosts to manage and no requirement of some of the business continuity features. Even if you do not make necessary, especially when your deployments include datastore with the n devices. Enhanced App Performance and Hybrid Cloud Take advantage of the latest innovations result: This is true for vSphere. Failed Error Code: Error when cloning an encrypted virtual machine with one or more unencrypted hard disks When you clone an encrypted virtual machine, the following error results if one or more of the hard disks of the virtual machine buy and comparison VMware 6.5 versions not. Because VMware does not guarantee that example A and B, vCenter Server renames B to A, so that the datastore has consistent labels across. When you attempt to add an the same NFS datastore with the across releases, you should not hard consistent labels across the hosts. If the VMFS6 datastore is backed by a n device, expand the esxcli commands, make sure to use. XXX Perform these steps: When mounting to no more than 2 vCPUs and the disk size to no code the name in the scripts. Run storage rescans only when absolutely ensure top performance for your critical. With some cycles of disabling and re-enabling, the hardware runs into a a large set of LUNs.
