UCSM 2.1.3a - Login Error: java.io.IOException: Server returned HTTP response code: 400

Recently I have run into an issue in a customer PoC and encountered a weird issue.  Everything looks fine except I cannot login UCSM.  The UCSM code I am running is 2.1.3a, and I have got the error message:

"Login Error: java.io.IOException: Server returned HTTP response code: 400 for URL: http://ucsm_ip:443/nuova"

Eventually I've found out the JRE 7u45 update breaks this, after lowering the version it works fine now.

Hadoop + Cisco SocialMiner = ?

What I am trying to do is to marry BigData Hadoop with Cisco SocialMiner, to collect the latest 1000 tweets on Twitter about Cisco, and analysis what is the most common words that people are using.

One of the beauty of SocialMiner is the API of it is very simple, just a HTTP request then you can get all your tweets in XML format.  You don't need to learn Twitter and Facebook API in order to collect the social contacts that you want.  This is how it works:


Several steps involved:
1. Setup Campaign in SocialMiner to collect Twitter stream with keywords Cisco, #Cisco and @Cisco
2. Write a little script on my Linux machine to get the XML file, and extracted the content of the tweets.
3. Copy it to the Hadoop HDFS, run the word count program.
4. Use Apache Pig, an abstracted level of Hadoop which allows you to use statement similar to SQL, to do the sorting.
5. Format the output in another XML file for graph plotting.  Done!


Looks like WebEx Meeting Server (on-premises WebEx) is the hottest topic now!

Cisco UCS Manager - Stateless Computing demo (English)

In my previous post I have created a UCS manager demo video about stateless computing in Cantonese.  Now I have updated another version of video with English voice over and hopefully can cover more people, enjoy and let me know what you think!

Cisco UCS Manager - Stateless computing demo


I have created a video to illustrate several demo scenario on how Cisco UCS achieve stateless computing, target to give you all a brief overview on our UCS manageability and how service profiles help to streamline the daily operations.

The video is voice over with Cantonese, sorry for those non-Cantonese speakers.  Will voice over in English when I have time.


Several configuration example has been touched on including:
- Pool creation (UUID, WWNN, WWPN, MAC)
- vNIC and vHBA template creation
- Service Profile template
- Create service profile from service profile template
- Associate Service Profile template with Server Pool to achieve service profile failover
- Rapid Server provisioning
- Server migration

UCS Manager + VM-FEX - Not compatible with VMWare vCenter appliance

Just come across an issue during the VM-FEX proof of concept test with customer, I am using UCSM 2.0 and trying to configure VM-FEX with VMWare ESXi 5.0 and vCenter 5.0.  We are using vCenter appliance 5.0, not installing the vCenter on Windows, for this test.  The result is after the integration, all VM can't be powered up.

After a quick search and found this KB:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2004079

UCS Manager with VM-FEX does not support the vCenter Server Appliance in any available release.


After we build a new vCenter on Windows (not appliance), everything is working fine.  :)

Ask the cloud

This is something I have created around 1.5 years ago.  Just found this video on my hard drive when I tried to free up some space of my hard drive.  This is a demonstration on how to control Cisco UCS Manager using voice recognition technology.

Cisco UCM + UCCX + VXML + DMS + UCS Manager + Nuance

At that time there is no Siri, yet, LOL
