HPE PDU Powershell module

As a follow-up of my exploration of the HPE PDU REST API I wanted to create a Powershell module as a wrapper for the API. I’ve previously written a post on how to create a Powershell module as a wrapper for an API here. The PDU module will be built in the same way where there will be a private function that handles the actual API requests

Automating two-node vSAN cluster setup

In a previous post I described how we are setting up remote offices for a customer with two-node vSAN clusters. I meant to get this post out right after that previous one, but things happened… Anyways, here’s how we automated those two-node vSAN clusters. Currently we have 7 of these racks ready with more to come. As these will be installed at distant locations we are extra keen on knowing that they are all configured as they should, and that the configuration is the same cross these multiple locations.

Slides and script from VMUG session in December

I had the pleasure of giving a talk about how to do monitoring of the vCenter Server during the VMUG Oslo meeting in December. The session was an extension of what I presented during the VMUG meetings in May and the vBrownbag session during VMworld Europe. The demos showed how we can get health status and metrics from a vCenter Server Appliance utilizing the new REST APIs shipped in 6.5 and 6.

vSphere Performance - vCenter Server Appliance (VCSA) monitoring

This post is a (late) follow-up on a previous post I did about exploring the monitoring endpoints of the vCenter Server Appliance (VCSA), and an addition to the vSphere Performance blog series. Now we will add performance metrics and health status of the VCSA to our monitoring solution. We’ll utilize the REST APIs in vCenter and feed the data into our Influx database and visualize it in Grafana. In vCenter we have the Appliance Management page also refered to as the VAMI.

Exploring the HPE G2 PDU REST API

Lately I’ve been playing around with the Redfish based REST API in the HPE G2 Metered and Switched Power Distribution Units. Through the API you are able to pull some details about the PDU as well as different utilization data. Based on your PDUs capabilities you should also be able to control different outlets. My focus has been to pull some details about the PDUs, and to pull the load on the different segments.

Automate disabling of IPMI over LAN access on HPE iLO

This article will describe how you can disable the IPMI over LAN access on HPE iLO. The IPMI protocol can present a security vulnerability where the authentication process for IPMI requires a server to send a hash of a user password to the client before authentication. This is not a new vulnerability and since this is a part of the specification of the protocol there is no fix for it besides disabling it or accepting it.

Extending the firmware repository in HPE OneView

This is a short post on how to extend the internal firmware repository in HPE OneView. The procedure is documented in the installation guide for 3.0, but if you are like me chances are that you don’t have that lying around so I thought I’d write up a short post on it for future reference. The process is pretty straight forward: Shut down the appliance Extend the hard disk to 275GB*

Slides from my VMworld session

Last week I did a session about Performance monitoring at VMworld Europe in Barcelona. The session was part of the VMTN Techtalks with vBrownBag. The slides (without the video demos) and the script used in the demo is available at Github. The session was recorded and can be seen on Youtube. Thanks to all that attended the session and to those watched it live on Twitch or have seen the recording afterwards.
