Cisco UCS East-West Traffic Performance.

The worst thing you can do in tech is claim something positive or negative about some technology without anything to back it up.  Ever since UCS was first brought to market, other blade vendors have been quick to point out any flaw they can find.  This is mostly because their market share of the x86…

Hacking UCS Manager to get pictures

I was reading the API for UCS manager the other day (hey, everybody has a hobby right?) and I found out a pretty cool place where the Java UCS Manager downloads the picture files.  I still haven’t found all the files (like the Fabric Interconnects and the Chassis, and IOMs) but most of the server…

VIFS in a UCS environment

First of all you may be asking if you stumbled upon this page:  “What is a VIF?”.  A VIF is a Virtual interface.  In UCS, its a virtual NIC. Let’s first examine a standard rack server.  Usually you have 2 ethernet ports on the mother board itself.  Now days, the recent servers like the C240…

Cisco @ SC’12

originally posted on November 16th, 2012.  Restored from Backup I just got back from SC’12 in Salt Lake City and it was as usual a fantastic event.  One of my favorite times of the year.  Most of this has to do with the fact that I’ve been going to this conference for almost 10 years so I’ve met…

Comparing HP blades to UCS in a 10 rack config

I really like infographics, so I thought I’d try to make my own.  I looked at a paper I wrote comparing 10 racks of UCS to 10 racks of HP blades.  The most astonishing numbers are the management.  My graphics can still use some work, but hey, you have to start somewhere, right?  Let me…

UCS Monitoring Part 2: Alerts for Bandwidth

This part 2 in my two part series on monitoring UCS.  Part one dealt with analyzing data and making sense of what UCS Manager already collects and displays for you.  This part will focus on alerting.  In particular, our objective is to give us a warning when the bandwidth utilization goes above 80% and a…

UCS Monitoring Part 1: Collecting and Analyzing UCSM Data

Usually its two related definitions:  Monitoring on one hand means looking at data, gaining visibility into what is happening on the system and being able to analyze it.  Monitoring also means alerting:  Let me know when something happens….

UCS: Rainbows, 6500s, and the Soul of a Server

My day job is to be an advocate for Cisco UCS in my customer’s data center.  Its a great gig.  Its much easier to back a product when you actually believe in it.  I thought I’d write down some of the ideas that I talk about with my customers on this blog. Rainbows In the…

Cisco UCS Role Based Access Control

One of the cool things that UCS allows you to do is create a place where different users of different organizations can go to to configure their pools of resources.  Its a common goal for many organizations to reduce duplication and allow agility and flexibility.  A multi-tenant solution that has been talked about can actually…
