UCS Performance Manager

Today I deployed UCS Performance Manager.  At first glance It appears to be a customized version of Zenoss with all the UCS goodies built into it so you can graph and trend over time the different metrics made available by the UCS API.  Therefore there is no agents that need to be installed.  I’m a […]

UCS Invicta iSCSI to VMware ESX

I have a 12TB UCS Invicta appliance in my lab I thought I’d try out.  The interface wasn’t as intuitive as I would have preferred, but the nice thing about it is that its simple and pretty easy to use once you get the feel of it. Invicta Configuration Create a LUN Navigate to the […]

Cisco, Cluster on Die, and the E5-2600v3

I was in a meeting where someone noted that VMware does not support the Cluster on Die feature of the new Intel Haswell E5-2600v3 processors.  The question came: “What performance degradation do we get by not having this supported?  And would it be better to instead use the M3 servers” This information they got from […]

Unauthorized UCS Invicta usage

I had a UCS Invicta that I needed to change from a scaling appliance (where more than one invicta node is managed by several others) to a stand alone appliance.  I thought this could be done in the field but at this point I don’t think its an option still.  The below info is just […]

FCoE with UCS C-Series

I have in my lab a C210 that I want to turn into an FCoE target storage.  I’ll write more on that in another post.  The first challenge was to get it up with FCoE.  Its attached to a pair of Nexus 5548s.  I installed RedHat Linux 6.5 on the C210 and booted up.  The […]

Changing UCS IP addresses

I have a UCS lab machine that I sometimes take to different locations for proof of concept work.  One of the things I regularly have to do is change the password and hostname.  Here’s how you do it on the command line: KCTest-A# scope fabric-interconnect a KCTest-A /fabric-interconnect # set out-of-band ip 10.1.1.23 netmask 255.255.255.0 […]

Cloud Computing: How Do I Get There?

This post comes from a talk that I’ll be presenting on at the Pacific Northwest Digital Government Summit Conference on October 2nd, 2013. History shows us that those that embrace technology and change survive while those that resist and stick with “business as usual” get left behind.  If we have the technology and we don’t use it […]

UCS Reverse Path Forwarding and Deja-Vu checks

UCS Fabric Interconnects are usually always run in end-host mode.  At this point in the story there really isn’t that many reasons to use switch-mode on the Fabric Interconnects. Two checks, or features that make End Host Mode possible are Reverse Path Forwarding (RPF) checks and Deja-Vu checks. Reverse Path Forwarding Checks Each server in […]

Backing up UCS

Backing up UCS can be a little confusing especially since it presents you a few options.  What you may be expecting is something simple like a one button easy “Back it up” button.  But in fact, that is not the case.  And the nice thing about it is there are lots of different things you […]

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 […]
