vSphere 6.5: HA & DRS improvements. Part I
Posted by Askar Kopbayev on March 2, 2017
5/5 (3)

A number of improvements that have been introduced in vSphere HA and DRS in the last several years are impressive. vSphere 6.5 continues this tradition by bringing new features into HA Admission Control, by adding flexibility with HA Orchestrated Restart and by enabling DRS to make more intelligent balancing.

I will be trying a new format today. First, I will be explaining the challenges you might have had in previous vSphere releases and then I will show you how the new vSphere 6.5 HA & DRS features address those challenges.

PowerShell ROBO

Picture this – you are a systems administrator working at a major banking institution.   The security team walks into your office and lets you know that a major update needs to be applied to all of the servers within the institution – not a problem for most organizations, but in the case of a bank, you could have hundreds if not thousands of remote and branch offices.  Sure, we can write scripts to copy out the update files and even execute them remotely from our head office – but the problem most ROBO scenarios are ever-changing – with new offices being created and others closing down all the time.  Keeping track of server names, IP schemes, etc. can be quite a time-consuming process.  Naturally, we want the same updates, patches, and fixes to be deployed everywhere, in the same manner, in order to provide consistency – so having this up to date list available when we need it is key to driving success within our environment.

Exploring VMWare’s VPID Technology
Posted by Gary Williams on January 11, 2017

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!
