CCNA Data Center

reloaded

Anybody thinking about going after this guy? I have been looking into it a bit, though there isn't any "official" study material out there for it. Lammle is releasing a book in June for the 1st test, but I guess the UCS stuff can be covered through some of the older Cisco Press material. Since I've been thrown into our team's Cloud Architecture team, I figured I'd take a break from my current cert studies to rock it out, since it would be directly applicable. Thoughts?

I know a guy pursuing this track, but he already has his 'IE for R/S, so more than likely he'd go towards the 'IE for Data Center.

Since I'm not sure of what you mean by "current studies" I don't know what to tell you.

However, I do know that certifying in what you're doing kind of just "makes sense".

Hope this helps.

From what I can tell the first test is a basic network rehash but the second test is where the meat is. FC zoning is a big deal in the datacenter, our SAN admin is a $100,000 a year employee. I would recommend some books on storage networking and looking into some materials from the Brocade track since they are the 'cisco' of the FC world.

My boss and I have already discussed the possible purchase of a UCS chassis for our lab later this year. Since we're already running Nexus in our Core, this is definitely on the radar.

Try these books in the meantime:

It is important to understand what is actually happening in the Nexus line of switches. In essence, they forked the operating system out of the MDS line of FC switches and put it atop a familiar ethernet chassis. The Nexus is more like a traditional FC switch than an ethernet switch. This allows the "convergence" of FC technology (in this case TRILL) on top of regular ethernet. When I design a network like this instead of rSTP or regular LACP trunks I get a SAN style of networking using ISLs - which is superior than traditional ethernet when you are sending traffic that needs ultra low latency and zero possibility of going down [storage] even something as quick at rSTP re-convergence is too slow.

UCS stuff is cool but most of the datacenters I know actually use their MDS/Nexus stuff with Dell or HP chassis since they are so much less expensive. The converged mezzanine cards for the UCS chassis are rebranded Emulex's which pop up in Dell and HP stuff so you are able to do the exact same thing through other providers that UCS offers. I only say this because I encourage you to learn the real meat of the technology instead of just say, the UCS platform, since the former will be much more useful.

I will be sitting the CCNA DC (both exams) sometime in the next month if work allows. My work has asked that I get it, and since I've done nothing but data center work for the last 6 months, it shouldn't be too bad.

I plan on using a lot of Cisco docs, the UCS simulator, hands-on experience (40 hours a week of nexus), and a couple of older cisco press books. I'm also using Cisco Unified Computing System by Silvano Gai/Tommi Salli and Roger Anderson (printed in 2010).

A colleague of mine who passed both exams said the first exam was very similar to the CCNA, and the second really dove into detail, FWIW.

For the purposes of my work, we sell a boatload of UCS (and install/configure it), although I haven't had my hand in that portion yet.
