Capacity planning with vRops
Posted by Michael Ryom on January 18, 2017
5/5 (2)

Capacity planning is one of the tasks that every IT organization need to do, but most do very poorly. This is not out of bad will or lack of skills. Most often, it is because they lack a good way of dealing with all the changes, past, present and future. Most of them are also done reactively. Statistics may be pulled from vCenter and put into word or excel where graphs of past data points from a historical trend. This is then used to predict the future growth and based there of cluster sizing and purchasing decisions are made. Alternatively, the all too familiar, “we are out of resources. Hurry we need to buy more”, scenario comes into play. None of these capacity technics are very good. There is most properly a need to do things smarter.

Exploring VMWare’s VPID Technology
Posted by Gary Williams on January 11, 2017
5/5 (1)

I’ve been using VMWare’s VPID (Virtual Port ID) technology for some time now both in work and in the home lab but I was curious to see just how VMWare handled a NIC going down and then coming back up and it turned out to be a lot more powerful and smooth than I first though.

In my lab, I’ve got several HP Microservers and a mix of TP-Link and Netgear switches.
I’ve found the TP-Link switches to be perfect for a lab as they have 48 1GBit ports and 4 1GBit FC ports. They haven’t cheapened out like Netgear have with the link between the last two Ethernet and the first two FC. With Netgear, you can only use last two Ethernet OR the first two FC ports.
You cannot use all of the ports on the switch. With TP-Link, all the ports are available and I find the web GUI a little more initiative although I did experience a bug on the TP-Link where the SNMP Engine kept crashing. This was fixed in a firmware upgrade so it wasn’t a major issue.

Anyway back to VMWare and VPID!

5/5 (1)

As is well-known, VMware has released a new version of virtual VMware vCenter Server Appliance 6.5 in the new version of vSphere 6.5 platform. Now vCSA is Photon OS-based. It works faster; it is provided with built-in high availability tools and has a ready-to-use vCenter Update Manager (VUM).

Due to the numerous changes, many familiar features don’t work anymore, and the information below will help you to get back to the normal use of vCSA.

VMware’s vRealize Log Insight – The easy way to get datacenter insight
Posted by Michael Ryom on December 21, 2016
5/5 (2)

For those of you who do not know vRealize Log Insight. It is a log collector and analyzer, with a pretty, simple and intuitive GUI. An easy way of managing logs and messages from all your datacenter devices. Best of all, it is not a VMware only product! In that sense that as long as the message is in syslog format it can be ingest by Log Insight. Wait, that is not all. If the device does not support syslog, like a Windows server. The Log Insight agent you can install on the OS in question. The Log Insight agent can handle Windows event viewer messages and log files of any kind. So even applications that do not adhere to any of the normal ways of logging messages (like syslog or windows event viewer), can still be collected, by specifying the location and format of the log file(s).

VMware vSphere 6.5 – What to be aware of before upgrade?
Posted by Vladan Seget on December 6, 2016
4.5/5 (4)

VMware vSphere 6.5 has been released few weeks back and many users would like to hit the upgrade button. Not so fast. In this post I’ll talk a little bit about what to consider before upgrading to vSphere 6.5. One of the good news is that there are no new license keys needed for vSphere 6.5 so if you’re currently on vSphere 6.0 you don’t need to enter new license keys.

Planning is a pain, but it is necessary step. Also, playing with Firmware on your physical NIC cards and applying proper firmware-driver combination is a hard reality before even thinking going further…. I have experienced that recently when upgrading my pNICs to proper firmware/driver combination (Those were the x710-da2 Intel Hyper converged 10GbE adapters).

Below you’ll find few points which are essentials to every IT admin.

vCenter Server High Availability Review – Part 1
Posted by Askar Kopbayev on November 24, 2016
5/5 (5)

VCHA overview

High Availability for vCenter Server has never been as important as today when there are so many products dependant on vCenter, e.g. VMware NSX, vSAN, Horizon View, etc.

VMware tried different approaches to bring HA to the vCenter.

There has been vSphere HA for a long time. Although it can protect vCenter Server from hardware failure it doesn’t provide protection on the Guest OS level. So, if Postgres DB in vCenter Server Appliance gets corrupted you would have to restore vCSA from a backup copy or rebuild it from the scratch.

VMware Clarity – Why should you care

Vmware Clariy logo

I the mist of all the software VMware has released as of late, one has missed the radar of most people. I must admit, that this might not be as exciting as a new vSphere release, to most people. To me it is a tale of what is to come and it is a harbinger of new and exciting times where UI, UX and API are first class citizens of VMware’s software stack.
