Howto become a Cisco CCSI ?

November 13, 2020December 16, 2016 by Joost van der Made

I am CCSI #35056

When you got a Cisco CCSI number, you are an official Cisco Certified Systems Instructor. Several years ago I passed my CCSI exam and now I am CCSI #35056. I know the journey howto become a CCSI. The big question is, how do you get there ? During my 2 days of presenting and doing the lab, there was one attendee that failed on both topics ! Don’t think it’s easy. In the Netherlands there are about the same amount of CCIE as CCSI persons. There is a reason that the CCSI isn’t way higher then the amount of CCIE’ers.

Start

First of all you will have to pass CCNA. In the early days the instructors did have to pass at a higher rate. Nowadays passing is enough. This is the easy part. Now comes the challenge if you’re not working for a learning partner.

Really ? 37 minutes to install Cisco Hyperflex ?

November 13, 2020September 16, 2016 by Joost van der Made

Configuring the FI / UCS Manager

This week I went to a customer to install Hyperflex HX240 cluster with 4 nodes. Everything was already racked and stacked.

The first step is to configure the FI’s with ip addresses and a password. Just connect a console cable to the FI and your laptop. It’s easier to setup the FI-A and when the setup is finished then power on the FI-B. The procedure to setup a FI-B is already described at : http://dcccie.joostvandermade.com/?p=25

You should have the correct Firmware for the FI’s. Via the CLI or GUI you can upgrade the FI to the correct firmware. I prefer GUI although via CLI is also very easy. You can find the Dependencies int the Release Notes of Hyperflex

Storage is Dead! Long live Storage.

November 13, 2020December 19, 2015 by Joost van der Made

We all need storage and we need a lot!

Back in the early days I started with WordPerfect 4.0 (1984). If you typed “Hello World!” it was about 80 bytes. If you now a days type “Hello World!” in Word 2016, it’s 12 Kb. This seems not much, but there is way more overhead in the file then 20+ years ago.

Files are getting bigger and bigger, 4K video is around the corner and we want to have data of every device we connect to the internet. Loads of Storage is also used for the visualized servers.
SAN, NAS are “old” technologies which a lot of companies are using for ages. Sometimes it can be complicated and that’s why there are “Storage Experts“.

Converged Infrastructure was the first step into a new direction. Compute, Network, Storage and hyper-visors have good adhesion between the vendors and most of the time it’s automated.

Hyper-convergence is not only a buzz-word since last year, it’s growing.

Here are 5 reasons to choose for a Hyper Converged Infrastructure :
