Ran into a situation where I needed to log into vCenter Operations 5 without having to go through HTTPS. Fortunately, the UI VM seems to be running a modified version of SE Linux and thus I just had to alter the vCops Apache config to disable their HTTP redirect to SSL. It should also be […](image)

Passed my VCP5rshughes

Sun, 12 Feb 2012 16:20:37 +0000

So I’m one of the many who had until the end of the month to pass the VCP 5 without having to take the class. Honestly, I think VMware did a very fair job of making this exam relevant to implementation without focusing on limits that will change with every release. Granted, a lot has […](image)

Well, it’s almost that time of year again for VMware’s Partner Exchange hosted in Las Vegas. This year I’ll be attending and focusing mostly on End User Compute and Cloud Management. I’ve recently had some exposure to vCenter Operations 5 and have been really impressed at how they’ve executed the integration of Capacity IQ while […](image)

Cisco VIC Boot from SAN troubleshootingrshughesBoot from SAN Policy

Thu, 05 Jan 2012 21:28:00 +0000

Boot from SAN is not necessarily one of the easiest things in the world; however, Cisco UCS does take away a lot of the complexity with its Service Profiles and associated Boot Policies. I’m not going to get into an exhaustive post around booting from SAN on Cisco UCS as I think most people have […](image)

In the NX-OS 5.1(3)N1 release for the Nexus 5000 family of switches, Encapsulated Remote Switch Port Analyzer (ERSPAN) was finally added.

A couple of weeks back, NX-OS 5.2.3 was released for the Nexus 7000 platform. This was the first maintenance release for the long running train of the NXOS 5.2 software train.

Nexus 7000 Secret Decoder RingrshughesNexus 7k LC Features

Wed, 28 Dec 2011 20:46:36 +0000

A common problem in designing Nexus 7000 installations is identifying what features are supported with which linecard. Many people are accustomed to the Catalyst 6500 where all of the features are primarily driven from the supervisor while the linecards have limitations of scale. With the Nexus 7000, the features are heavily dependent upon the linecard as the […](image)
