Runecast Analyzer – Getting started Guide part 1

Part 1 – Deployment and Setup

Runecast Analyzer is a very useful tool to locate configuration issues within a vSphere cluster. It compares your installation against security hardening guides, best practices guides and the VMware Knowledge-Base (KB). Once you’ve set up your cluster everything might have been ok. Since then new issues might arise, problems get discovered and security guidelines can change. But your setup is still the same. It’s hard to read through VMware KB on a weekly or daily base. I would say it’s almost impossible. Some issues only occur in certain combinations of hardware, patch-level and firmware-level. That’s where Runecast kicks in. They check your setup against most recent information in the KB and hardening guides and present you a filtered subset of information with potential issues in your environment. So you can concentrate on fixing issues and don’t waste time in reading hundreds of new KB articles.

I’ve written a hands-on  introduction earlier this year. This time I’d like to focus on the product from an administrative point of view.

Licensing

Runecast offers a 15 day trial license without buying anything. But you’ll see only a limited subset of results.

As a vExpert there’s a special offer by Runecast. You’ll get a one year NFR license for up to 3 hosts without limitation. That’s the one I will use in the following sections. But even the 15 day trial will give a very good impression about the quality and usability of the product. Continue reading “Runecast Analyzer – Getting started Guide part 1”

Why you should replicate your vCenter Appliance

In the old days of virtualization a vCenter used to be a nice-to-have commodity. But these times are long gone (at least from an IT point of view). In today’s datacenter many services and applications rely heavily on vCenter. Some of the most common use-cases are VDI-environments, cluster balancing mechanisms like DRS or Storage-DRS and even backup software needs vCenter.

The last one is a crucial point. It’s good to have your vCenter Server Appliance (VCSA) backed up regularly and most of you and your customers will likely do so. But think of what would happen if you’d loose your vCenter for like 10 minutes or even an hour.

It’s not just important to have a backup of it – you also need to return to operation fast and minimize your Recovery-Time-Objective (RTO). Continue reading “Why you should replicate your vCenter Appliance”

Runecast-Analyzer 1.5 – Hands-on

VMware veröffentlich in regelmäßigen Abständen neue Artikel in der VMware-Knowledgebase. Darüber hinaus gibt es Hardening-Guides und Best-Practises Guides, deren Inhalt immer wieder aktualisiert und angepasst wird. Hier verliert man schon einmal den Überblick, welcher der ESXi-Hosts noch im Einklang mit den Guides, oder den KB-Artikeln ist. Er war es vielleicht zum Zeitpunkt der Installation, aber inzwischen können sich viele Dinge geändert haben.

Auftritt Runecast-Analyzer

Hier kann der Runecast-Analyzer ein wertvolles Hilfsmittel sein. Er analysiert automatisch vCenter und ESXi-Server, vergleicht die Installation gegen aktuelle KB-Artikel, Hardening-Guides und Best-Practises Guides.

Die Installation ist recht einfach. Die Runecast-Appliance wird im Cluster bereitgestellt und mit dem vCenter verbunden. Soviel zur Konfiguration. Seit der Version 1.5 können auch mehrere vCenter mit der Runecast-Appliance verbunden werden.

Die Analyse erfolgt nicht in der Cloud, sondern im eigenen Datacenter. Es werden also keine vertraulichen Daten an Dritte weitergegeben. Continue reading “Runecast-Analyzer 1.5 – Hands-on”
