The VCE Model : Yes, it is different

This post comes out of a slide deck I authored last week for a partner event. I decided I was going to try and illustrate why the VCE model really is such a different approach to other datacenter and private cloud models.

Normally my blog is light on vendor specific commentary. I see myself more as a virtualization geek who just happens to work for an awesome company (EMC) than a hardcore analysis/blogger. But I have seen so much messaging lately that distorts the VCE message, I really felt the need to offer my own perspective. [Read more...]

Between a Rock & OSPFv3 : My Cisco CCNP Test

Cisco Systems Logo

will make your head hurt

Hard to believe but I have been a CCNA for almost three years now. October is the three year anniversary which also makes it the month my CCNA expires. I had planned on moving on to my CCNP tests well before the three year deadline but I got distracted by becoming a manager, having two more kids, and fall head over heels into virtualization with VMware.

Even with all the distractions I still studied when I could. The plan was to take the tests one by one and whittle them down. A new problem arose when Cisco decided to update the tests. They put a firm July, 31st 2010 deadline on the tests I had been studying for.

So now I had two deadlines. I had one deadline for having to start all over (October) and another one to get at least the two big tests or the bigger composite test out of the way.

Well, time has a way of sneaking up on you and in the beginning of this month I realized I had 31 days to pass either both Building Scalable Cisco Internetworks (BSCI) and Building Cisco Managed Switched Networks (BCMSN) tests or risk it all by taking the composite test which combines both. On top of this I was booked for at least two weeks of customer calls and side projects for my team.

About two weeks before the deadline I booked the test. July 31st @ 11:00am. Only one shot because by the time I walked out, the test would be retired.

I locked myself in my office that whole week beforehand. And with a steady supply of coffee, Reese’s pieces, Dr. Pepper, bottle of water, and stress I proceeded to find everything I didn’t know and beat it into my head.

I used a combination of Cisco official material, a TON of the Cisco configuration guides, and a big GNS3 setup on my workstation. I did everything: OSPF, IS-IS, EIGRP, BGP, IGMP, PIM DM/SM/DM&SM, etc, etc. I forced myself to sit for hours and build an entire set of autonomous networks and then integrate them without looking at the book. If I did have to look at a guide or book, I would do it again until I didn’t. I focused mainly on the big routing protocols that I don’t touch on a day to day basis.

I did this for at least twelve hours a day that week. No video games, no beer, no fun, and not much family time. Brutal but I couldn’t risk missing the test on Saturday.

So the test day came. I had gone to bed at 2:00am and woke up at 7:00am to start reviewing OSPFv3 and IPv6 stuff before the test. When the time came I drove down and lined up along with about seven or eight other Cisco procrastinators. It took 30 minutes before my testing workstation would work and about 11:30am I got started.

I have taken some hard tests before. This one was no joke. They threw stuff at me I didn’t expect would be as big a part. The questions were rough and many require that intimate knowledge you only get by doing. By far my lab work was answering most of the questions for me.

After waiting for eight long minutes the testing machine informed me that I had passed. I almost dropped out of my chair. While I was sitting there two other exam takers had finished and from their frustrated curses and storming out I was sure my fate was the same.

The surprising thing is, I did much better on the stuff I had not used. I actually got dinged on some things I know and have done, i.e.VLAN hopping, QoS tagging, etc. I actually scored 100% on several categories including BGP, OSPF, and ISIS.

I am still not officially a CCNP yet. I have to take the TSHOOT exam which I am much more relaxed about. I have however held off the Cisco expiration monster for another three years from my precious CCNA :)

My next goal after TSHOOT? Don’t know 100%… I need to upgrade my MCSE2k3, start my VCDX, continue my EMC path, and start my RHCE path. Good to have goals I guess… But first, maybe another swim in the pool with the kids…

Geek week : How to build an empire in 6 days

[printprofile]

15 EMEA based vSpecialists, too much caffeine, the smell of last night’s pizza, and a seemingly impossible list of tasks to accomplish – that was Geek Week Q2 2010.

EMEA vSpecialists

As a vSpecialist at EMC, we attend a lab construction week as part of the on-boarding and initiation ritual. The instructions are simple: take this list of applications and infrastructure configurations, and work as a team to install and configure them all with the kit we provide to you before the week ends. There are multiple objectives for Geek Week, the main ones being; get the team working together, learn about integrating EMC, VMware, and Cisco technologies, and develop a good understanding of technologies that are not yet released, so we are best able to support our customers at product launch time.

To kick off the week, Scott Lowe and Chris Horn dive into the details of what they expect from us:

With the equipment you have been given, please deliver the following by COB Friday:

  • Rack, stack, cable all equipment (build a Vblock 1, and connect the non-Vblock components into their own environment)
  • Upgrade EMC CLARiiON CX4 platform to FLARE 30 (prerelease)
  • Upgrade EMC Celerra platform to DART 6 (prerelease)
  • Upgrade Cisco UCS firmware, and UCS Manager to the latest release
  • Install VMware vSphere 4.1 including vCenter Server 4.1 instances deployed as VMs (prerelease), and configure NFS, and VMFS datastores
  • Configure hosts to use Cisco Nexus 1000V and PowerPath/VE
  • Use Unisphere to configure storage and present the storage.
  • Configure sub-LUN auto-tiering on the CX4(s) to move data automatically between the FLASH, FC, and SATA drives
  • Connect VMware ESX 4.1 hosts to the CX4 array and enable VAAI support storage hardware offload (prerelease)
  • Set up 3 Atmos VMs and configure Atmos clients to use its storage
  • Deploy VMware View 4.5 including a regular View Manager connection server as well as a Security Server
  • Set up RSA enVision and configure it to monitor and correlate events from the VMware ESXi 4.1, vCenter 4.1, and VMware View 4.5
  • Install Active Directory, Exchange 2007 and Replication Manager 5.2.3
  • Configure Ionix UIM V2 to discover the Vblock 1 infrastructure (prerelease)
  • Install two Celerra VSAs, and configure Celerra Replicator
  • Install VMware SRM 4.0.1 using NFS, configure failover scenarios, invoke failover and failback with the agent for Celerra
  • Install Avamar Virtual Edition and setup a backup schedule to protect all VMs, either through agents inside VMs, or through integration with VADP
  • Install VMwares Redwood Software (prerelease)

So how did we go? We started by mapping top down requirements of all of the applications, and their dependencies. We created some naming conventions and standard usernames/passwords. We drew up an infrastructure schematic that we could follow, and we took volunteers to lead each of the first round of tasks.

Once we felt like we had a plan, we walked into the data center to look at our equipment. It then went a bit silly for a while, like kids in a candy store :-) . Everyone started grabbing at cables, connecting systems, opening terminal sessions to devices, and just geeked out. We all got so excited it is actually quite funny looking back at it now.

Nonetheless, we stuck to the plan and ended up closing off all of the tasks within the allotted time period. A pretty big accomplishment given there were only a few of us that have been with EMC for longer than 2 months. Well done EMEA vSpecialists, it’s a pleasure to work along side you all!

The technology highlight for me…

One of my favorite tasks was configuring the Vblock 1 storage (CLARiiON CX4-480). After deploying FLARE 30 I had to configure sub-LUN auto-tiering (Fully Automated Storage Tiering / FAST). The idea of FAST is that the system watches the access profile of information stored inside FAST storage pools and automatically promotes or demotes 1GB chunks of data between tiers based on the real application usage pattern requirements. In this particular array I had the following drives available for use:

  • 5 x 400GB FLASH
  • 4 x 200GB FLASH
  • 15 x 300GB 15K FC
  • 15 x 1TB 7.2K SATA

I left aside 4 x 200GB FLASH drives for FAST Cache (might write something about FAST Cache later) and created a new RAID 5 FAST storage pool with 5 x FLASH, 10 x FC, and 10 x SATA. This configuration should theoretically deliver a total of 12,600 back end IOPS (10.000 FLASH + 1,800 FC + 800 SATA) with a desirable response time, while also delivering a little over 10TB of usable capacity.

FAST Storage Pool

The interesting thing about this whole process was how easy it was to create this pool of storage with auto-tiering. I neglected to record myself creating this particular pool but I created another pool yesterday out of FC and SATA so that I could create a demo the simplicity – check it out:

YouTube: Create FAST Storage Pool

Next I created LUNs (All Thin provisioned) and allocated them to the ESX hosts. Once we started using the storage for our various projects we were working on, the CX4 started auto-tiering. I guess it was inevitable that almost all of the storage would end up on FLASH as we had enough FLASH in this pool to store all of the written blocks. Here is the tiering status of the storage pool which shows how much data is about to be moved, where it’s moving from and to, and how long it will take.

Pool Tiering Status

All in all, I’m extremely impressed with what the EMC engineers have come up with here with sub-LUN FAST, it’s yet another score for storage administrators, allowing them to spend less time optimizing and more time innovating. Which of your applications would you allow FAST to automatically optimize?

Cisco Live 2010 : Things to do in Vegas

Eric Hollis & Chris Horn discussing VCE

Ok, if you are at Cisco Live 2010 and have any interest in the new Private Cloud innovations or in Virtualization, I have a who’s who of EMC vSpecialists onsite that you must meet.

1. We have in one location two of the masters of the VCE SST team. These guys eat, sleep, and breath Vblocks all day. Chris Horn, and Eric Hollis are the busiest vSpecialists and other than maybe Chad Sakac or Wade O’Harrow, have more face time with customers looking at private clouds than anyone. I highly recommend swinging by booth 1671 and asking to meet them. Tell them Nick (@lynxbat) sent you.

2. There are people who are in the know at EMC, and then there is Stephen Spellicy. This guy is involved in helping with product development, testing, and demo building across all parts of EMC. Have a question on Redwood UIM? Where EMC is going with Cisco and VMware? No other guy at EMC that I know of (I admit, not a long list…) is working the technology in the trenches like Stephen. He is also working the booths for VCE and EMC Journey to the cloud.

3. But, I am not done. We also have my step-brother (by employment) David Robertson. Storage guru, FCoE master, Nexus 5k experienced geek and a half. Have a difficult storage/FCoE/VMware question? I bet $10 Dave will have it answered for you in a very short and intense conversation.

4. Alongside the above we have John Avery (VMware, Cisco master), Jeff Thomas (Godfather of the West Coast & Virtualization for EMC), and Rick Scherer who just may be the only VCDX at Cisco Live (or at least that I have run into…).

EMC also has a great RSA booth, is a part of the Datacenter of the Future demo with Cisco, and great video demos of new Infrastructure as a Service (IaaS) technologies.

I am also wandering around so if you want to meet up and talk about anything hit me up on twitter(@lynxbat). I will be at the Mandalay Starbucks today @ 9:30am for an EMC tweetup also.

The point being that EMC has sent their best and brightest (myself not included) so you can approach and ask the difficult questions about where you want to go with your datacenter. Take advantage before the conference ends. Even John Chambers had to drop by and see (see below).

Cisco Live 2010 : It’s all about the Milk & Cookies

DAVOS/SWITZERLAND, 30JAN10 - John T. Chambers,...

Watching John Chambers, CEO of Cisco, give the keynote presentation today at Cisco Live 2010 I was struck by two important things:

  1. The focus on changing the way the consumer / business users utilizes technology
  2. The strong emphasis on the demand for a new model for business operations.

Both of these appear on the surface to be great marketing statements. But, what makes these different is the timing with the evolution of technology today.

I think the value proposition of the video on every business/consumer device is obvious. I know the Cisco Cius brings the capability to change the way interactions occur and collaberation begins. But, what affected me most was a simple statement that Mr. Chambers made:

“Today, change starts from the consumer and moves to the datacenter”

It just clicked for me with this statement. The drive for the private cloud, for infrastructure that is flexible, agile, and easily consumable is based on demand. It isn’t based on just the energy savings, cost efficiency, or enabling of new technology.

The consumers want more. They want their milk with their cookies. They want to do things quickly with lots of choice and a multitude of interaction. This trend is obvious with devices like iPhones, iPads, Flip Video, even mobile hotspots like Sprint Overdrive.

And because the consumers want more and the competition to fill that need accelerates; business development is demanding more from the way it interfaces with technology. The point being, that the acceleration of technology is imposing an demand on the way business is done today.

John Chambers illustrated this by pointing out the massive changes Cisco has done itself to the way it does business. The amount of patents, new products, and different markets Cisco is participating in is incredible. Their success is strongly tied to the speed with which they deliver new technology and business development.

The big two pillars that were built for this were Operational Excellence and Innovation. And John made strong statements around the VCE coalition (VMware, Cisco, EMC) and how important virtualization implementation from the consumer to the datacenter has become.

The idea of a business model where technology is a consumable that is distributed, flexible; and most importantly fast to deliver, is compelling. Another powerful statement was that the greatest obstacles are the culture and process and not the technology architecture itself. The strong focus is on modernizing the business architecture to be able to fully utilize the new technology innovations around the private cloud.

In the end, demand for interaction in our hands and between each other has created the demand for collaboration in the datacenter.

Having seen the focus at EMCWorld 2010 and now the strong alignment at Cisco Live 2010 I am excited to see what lays in store for VMworld 2010.

What happens in Vegas… : Cisco Live 2010!

Seems like I somehow get myself involved in everything lately… This week I am headed to Cisco Live 2010 although for this one, I was begging to go.

While a true blue EMC guy and VMware lover. I am also secretly a big fan of Cisco stuff. I love how they are always on the cusp of new technology. I also love networking and I am a huge fan of the new movements into Data Center Networking 2.0. My VMworld session this year is on virtualization and how it affects the way we look at networking.

I will spend my time this week tweeting and blogging about what I see and hear at Cisco Live. I will also spend some time at the great EMC booths including our Journey to the Private Cloud booth. Feel free to drop by and say hi. Also, EMC is hosting a TweetUp at the Mandalay Starbucks Wednesday @ 9:30am. Come out to meet all the killer Cisco competent vSpecialists and EMC peeps.

I am also going to take my CCNP composite test this week so if you run into me and I look like I have been studying all night; you will understand.

If you have something you would like me to look into and blog about, please post a request in the comments. I will try and respond to each and everyone I can.

See you there,
