Reading Time: 4 minutes VMware has just officially announced that their certifications will change the names with something different and no more related to the product version. New certification names will be identified by the year they are earned. Potentially this will make easier to immediately identify how current a certification is.

There are other NSX products, but VMware has just announced a new minor version for the vSphere related product: NSX Data Center for vSphere v6.4.2 it’s out.

Reading Time: 3 minutes If you still are using the Windows based vCenter Server with a SQL Server database you may have some login issues, due to a recent Windows update (released on July 10, 2018). You will have some errors in the SQL Server part with SQL startup issues due to “TCP port is already in use” errors. This is caused by a regression in the TCP/IP functions that manages the TCP port pool introduced in the July 10, 2018 Windows updates for Windows 7/Server 2008 R2 and Windows 8.1/Server 2012 R2.

Reading Time: 4 minutes Two years ago, VMware has started new vExpert (sub)programs on different technologies. One of those sub-programs was the vExpert NSX and I was honored to part of the first list. After the renewal of last year (VMware vExpert NSX 2017), I found that I’ve been renewed also for this year! VMware has just announced the list of vExperts NSX 2018.

Reading Time: 3 minutes Dell EMC OpenManage Server Administrator (OMSA) is a complementary tool that provides a comprehensive, one-to-one systems management solution in two ways: from an integrated, web browser-based graphical user interface (GUI) and from a command line interface (CLI) through the operating system. Usually, you should add it to each bare metal system, unless you are using other management tools. But also if you are using Open Manage Essential (OME) or similar, OMSA provide some unique and powerful features, like the access to the BIOS settings.

Reading Time: 3 minutes In the last Veeam Community Forums Digest newsletter there is an interesting note about possible performance issues in VMware vSphere backup based on hot-add transport mode. VMware has confirmed that the increased Hot Add times experienced by some Veeam customers who have installed Veeam Backup & Replication Update 3a and the reason is the latest Virtual Disk Development Kit (VDDK) 6.5 version used in U3a to support also vSphere 6.5 Update 2.

Reading Time: 3 minutes One common way to backup the VMware vCenter Server Appliance (VCSA) is to manage as a common VM and use a backup solution to backup (and restore) the entire VM. But it’s approach does not always work, for example in the case of a database corruption the VM restore could be not working. Starting with vSphere 6.5 and the new VCSA 6.5 was possible to use also a native backup solution integrated with the vCenter Server Appliance Management Interface (VAMI). But it was a manual operation (some scripts are available to automate and schedule it).

Reading Time: 7 minutes Note that this post becomes obsolete with the vSphere 6.7 Update 1 release where the client it’s finally complete. Some months ago I’ve written a post (Is the HTML5-based vSphere Client ready to replace the vSphere Web Client?) on the limitation of the new vSphere Client, but this was before the vSphere 6.7 and vSphere 6.5U2 releases. VMware vSphere, during its history and the different versions, has got several types of Graphical User Interface (GUI) client. One of the most used (not the first, but the standard one since Virtual Infrastructure 3.0) was the vSphere […]

Reading Time: 2 minutes VM Explorer is another backup (and replication) tool with native support for virtualized platforms (vSphere and Hyper-V) with a good success in the SMB segment. Initially was build by a Swiss company (Trilead), acquired later by HP(E) and recently acquired by Microfocus. Lot of changes in the name, but not in the substance and with a good development and release cycles. Now Microfocus has released a new VM Explorer release (v7.1) compatible with the latest version of VMware vSphere 6.7.

Reading Time: 3 minutes VMware vSphere provides a different way to copy the VM data during a backup operation: those modes are called transport modes. There are at least three major transport mode: network mode (or NBD), hot-add mode (or VM proxy mode), SAN mode (of storage offload mode). Most of the backup products can use those different transport modes depending on the configured infrastructure and the requirements.
