Reading Time: 3 minutesSeems that there are still some issues with vSphere 6.5, with a possible PSOD (Purple Screen Of the Death) after upgrade to 6.5U1 on ESXi hosts using 10 Gbps NICs. The VMware KB 2151749 describe this issue and explains that this occurs because Netqueue commit phase abruptly stop due to the failure of hardware activation of a Rx queue. As a result, Internal data-structure of the Netqueue layer’s could go out of sync with the device and cause PSOD.
Reading Time: 3 minutesIf you are going to using vSphere Replication you will notice, after the deployment of the two virtual appliances a continuous (also each minute) logging of installation activities on all the ESXi hosts in the protected cluster. This is quite annoying but also is going to fill up your log both in the ESXi hosts and in the vCenter database (are all tasks visible in the the vCenter console).
Reading Time: 3 minutesThe Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, usually with Ethernet standard. Compared to Cisco Discovery Protocol (CDP) it’s not proprietary and can be used from different vendors. VMware vSphere adds LLDP capability in the Distribuited Virtual Switches (DVS). CDP it’s also available both in DVS, but also in standard virtual switches (by default it’s enabled in listen mode).
Reading Time: 3 minutesIn a VMware infrastructure, when you build a new VM, the default compatibility level could depend on your vSphere version, from which client you are using (the legacy vSphere Client does not ask for VM virtual hardware version in the default wizard), but also from your cluster settings. VM virtual hardware version defines exactly the compatibility level, but you can define the default level using the vSphere Web Client or the new HTML5 Client.
Reading Time: 6 minutesUsually when you upgrade to a new version of a product you may need also a new license key for it. But it’s not always true. For most of VMware’s products (for example VMware vSphere) a new license key is needed ONLY if you change the major number.
Reading Time: 2 minutesOne propertiers of VMware (standard) virtual switches was the number of ports per switch. A parameter (120 was the default in ESXi 5.x) that define how many virtual NIC and/or vmkernel interfaces you can connect to the virtual switch portgroups. This parameter was static and any changes require a host reboot. But starting with vSphere 5.5 (see KB 2064511) this parameter has become “elastic”.
Reading Time: 2 minutesSeveral people are disabling IPv6 support in ESXi for different reasons: because of the minimum privilege principle (if you are not using a service, why you have to keep it enabled?) or simple because they don’t want any IPv6 address in the network. On Linux and Windows systems is become very difficult disable it and Microsoft itself does not recommend disabling IPV6: ” We do not recommend that you disable IPv6 or its components, or some Windows components may not function.” (https://support.microsoft.com/en-us/kb/929852)
