EMC WORLD – Day 3 – The Casino, Legos and EMC Elect

Sorry for Day 3 being late.  Too bad it isn’t because I won so much money gambling that I’m driving my new Ferrari back to Raleigh.  Lots of stuff did go down on Wednesday at EMCworld and the night before.

The first thing I would like to mention is a HUGE shoutout to our awesome Varrow customers that I got to spend time with Tuesday night at Sushi Samba and subsequent other places on Las Vegas Blvd.  We had a great time eating sushi, and cooking Kobe Beef slices on a huge rock.  It was a nice time.  Here are some shots I took:

.

So Wednesday I had a chance to hit up the blogger’s lounge and invade the EMCElect Space.  I had a great conversation with @colinmcnamara and @mjbrender around what it takes to be EMC Elect and why I was rummaging through their Polo shirts (I ninja skilled my way in to retrieve these for our very own @thejasonnash and @virtualtacit).

I learned a bit more about EMC Elect and how it would be really cool to be a member.  If you would like to learn more and nominate someone (or yourself!) go to: https://docs.google.com/forms/d/1Msk1obeUw1v-VwvRDEo3m3wOVGLZ0IvTlYEErnWhewQ/viewform

You have until November to submit.  It’s really cool.

I got some really sweet Legos from the VCE booth.  ”No Assembly Required” at least for the VBLOCK part.

I also attended VMAX best practices and the VMAX birds of a feather session…  That I will have to save for another post!

EMC WORLD 2013 – Day 2 – No Tigers, Just Awards and Superheros

Hello!!!!  I did not end up stealing Mike Tyson’s tiger last night… unfortunately.

I did however witness my company Varrow winning…for the 5 consecutive year the EMC Services Quality Award.

Pictured are a bunch of folks from Varrow and I managed to sneak a picture.  Here is the banner of the recipients.  (BTW, 1 7 year, 2 six year and 3 five year award winners).

I managed to talk with some VMAX folks during a session about the new VCOPs plugin’s for VMware, and have a deep dive discussion around FAST technologies and how they are used in customer environments.  It’s real nice to talk with engineers that actually work on the products day to day and less marketing stuff (no offense to my marketing friends!!! I’m just a geek).

…and finally.  There is this superhero theme going on.  Still not sure about that but managed to get a shot with some X-men.

EMC World 2013 – Day 1 – Vegas!

I have arrived in Vegas for EMC’s annual conference.  After fighting my way through Raleigh to Charlotte, and a “Taxi Line from Hell” at LAS it is very good to be here.

This is my first time in a few years since I presented in Boston back when I was an EMC Customer.  Lots of things have changed and lots of things remain the same.

First, it still is a very cloudy cloudy world.  What surprised me is that there doesn’t happen to be clouds hanging all over the place as in previous years, however I would say that the buzzword is still there and still flows through presentations and key notes freely.  The one thing to note though is that “Cloud” is a bit more defined than years of past and perhaps we’ve gone beyond buzz to something that is actually quantifiable.  Which makes people sound WAY more intelligent than back in 2009.

I also am enjoying Las Vegas and what it has to offer.  This place is a bit crazy, smoky and outright strange sometimes but with a bunch of IT professionals, 174,480 cups of coffee served [from the Jeremy Burton's @jburton keynote] it is bound to be a great time.

Looking forward to the solutions pavilion, networking with fellow EMC fans and partner awards tonight!!!

The Mechanic

Early last week my commuter car suffered a catastrophic failure in its ability to cool itself properly. This led to a bit of smoke coming out of the back of the car and left me stranded on the side of the road. As cool as it was to experience smoke coming out of the back of the car, I wasn’t driving the Bat Mobile trying to escape from the Joker. As I reached for my Bat-Phone (woops sorry…iPhone) I quickly turned to my USAA App and a tow truck was dispatched.

As I was waiting for the tow truck I was thinking to myself, “Self, how could I have prevented this?” One I could have listened to my wife when she said, “Hey the car was sounding weird, why don’t you take it to the mechanic before you start driving it?” but of course being a warm blooded male of the human race, I kindly dismissed the idea and kept driving…until I ended up in the current situation I was in.

God Made an IT Worker

I know it’s been a couple weeks since the Super Bowl, but during halftime I saw that advertisement about farmers…you know the one…  It’s a very good ad.  Filled with emotion, triumph, hardship and otherwise really cool stuff.

Then, I thought to myself, “Self”…”How come Farmers have all the fun?”… ”Us IT Folks have fun too!”.

So whilst the inspiration for this next video comes from eating way too much Super Bowl Chili with bacon in it…I present to you, in my own words and possibly other geeks like me, “God Made an IT Worker“.  @sangeek

Barry Sanders beats Michael Schumacher: VMworld Call for Papers Voting 2012!

This year it is my honor to be able to submit to present at VMworld 2012.  Public voting is a great way for VMware to gauge what’s hot and what’s not and choose sessions that people would be attending during the event.  I would guess that buy doing this it increases attendance, awareness and overall geekery during the conference.

While I’ve been a little silent on the scene since my presentation at EMC World 2010 and this year’s Varrow Madness I can tell you it is not from lack of interest in presenting!  I’m never very good at tooting my own horn, but hopefully this years session is a blast.

Here is my abstract:

Session: #2239 Deciphering the Mystical World of Storage Performance

Abstract:  An introduction to SAN and NAS attached volume types within VMware. The purpose of this presentation is to help VMware and Storage administrators that are new to the virtualization scene to appreciate the implications of RAID types, drive performance, throughput and bandwidth in an easy to understand and fun way.

This session will break down the differences between Network (iSCSI, NFS), and Fiber Channel storage but not be vendor specific. In addition the usage of certain drive types, what they are good for and what they are not good for will be discussed. Example production environments will be shown to include VM and Storage as a Service, archival, and application delivery.

Cool huh?  I hope it will be.  I don’t want to get crazy on specific vendors feeds and speeds, how much cache they have or that twenty thousand EFD’s in an array beats Michael Schumacher and Barry Sanders in a game of horseshoes. I want to get down and dirty into the science of it all.  As my Physics teacher once told me Physics is Phun!

If you could please vote for me, I would really appreciate it.

You can clicky here

Also while you’re at it, please consider voting for my other co-worker colleagues and here are their session abstracts:

Joe Kelly (blog:  http://blog.virtualtacit.com/) and Michael Bailess from American National Bank are submitting:

Session: #1883 – Deploying an Active/Active Datacenter with SRM 5

Abstract:  In this session we will discuss the challenges that face a single physical datacenter as well as how these challenges can be resolved with SRM 5. We will explain the design that we deployed at American National Bank which did not include more expensive technologies that would have been needed to run a stretched cluster environment. American National Bank has implemented their own private cloud that is not linked to any physical site. This solution saved American National Bank from long late night maintenance windows to correct facility issues, spread the load between to geographic regions, and created a DR plan that can be fully tested daily.

Tom Cornwell (blog: http://blog.piratesjade.com/) submitted:

Session: #2848 Cloud Continuity: How Does the Cloud Fit into Your Business Continuity Plan?

Abstract:  Today cloud is becoming ubiquitous. However, it can be utilized in many different was. Whether you utilize cloud for your production environments or not, cloud can play a part in your business continuity plan. This session describes different business continuity strategies utilizing cloud. Topics include: cloud as a source, cloud as a target, and cloud to cloud DR. In addition, we will discuss mixed strategies and different types of cloud implementations including Platform-as-a-Service, Infrastructure-as-a-Service, Storage-as-a-Service, and DR-as-a-Service.

Jason Nash (blog:  http://jasonnash.com) submitted four sessions focused on networking:

Session: #2181 – Cisco Nexus 1000v: Architecture, Deployment, and Management

Abstract:  This session will walk attendees through the architecture, deployment, and management of the Cisco Nexus 1000v virtual distributed switch. The information in this session is based on experience with numerous production deployments of the Nexus 1000v and the audience will benefit from many lessons learned from the field. The session begins with a high-level overview of the 1000v’s design and components followed by several considerations and preparations that anyone looking to deploy this new distributed switch should consider. This includes items such as network design, existing network infrastructure, and overall integration in to the organization’s IT processes. Next, the focus will shift to technical details of the configuration process and several examples will be shown covering many of the common scenarios seen in the field. Day-to-day operations and management of the switch will be covered in detail and include routine items such as adds, moves, and changes, as well as upgrades and maintenance. Finally, a section on troubleshooting processes and information will give attendees the tools they need to support their new virtual switch.

Session:  #2197 - A Deep Dive on Virtual Distributed Switching & Cisco Nexus 1000v

Abstract:  This session will provide an in-depth look at the distributed virtual switching technologies available in VMware vSphere. The discussion will start with an overview of both the integrated Distributed Virtual Switch as well as Cisco’s Nexus 1000v. We will compare and contrast the options highlighting features, functionality, management, complexity, and operational considerations. Each available option provides its own set of features, functions, challenges, and design and deployment considerations. During the session the components, design and implementation considerations, as well as troubleshooting recommendations will be covered in depth. Attendees should expect to walk away with the knowledge they need to decide which of these technologies fit the requirements for their environment as well as the understanding to deploy them.

Session:  #2207 - vSphere Distributed Switch – Technical Deep Dive

Abstract:  While the vSphere Distributed Switch (vDS) has been around since vSphere 4, vSphere 4.1 and 5.0 have added a number of enhancements. This session will provide a technical deep dive in to the vSphere Distributed Switch. This includes design and deployment considerations, configuration, migration steps, tuning, and troubleshooting. Special attention will be paid to migrating an existing production environment from the standard vSwitch to the vDS with no or very minimal disruption. Extended features such as Network I/O Control (NIOC), Network Resource Pools, and Load-Based Teaming (LBT) will be discussed in depth with use cases and recommendations given. Finally, methods and tools for troubleshooting network connectivity and performance problems will also be highlighted. The inclusion of accessing a live lab environment will make for a very interactive session.

Session:  #2463 - vSphere Physical Connectivity – Deep Dive & Best Practices

Abstract:  This session will provide an in-depth look at your options for physically connecting vSphere hosts to the network. The discussion will center around common question areas that come up during knowledge workshops and customer design sessions. Throughout the session videos and animations will be used to help attendees easily see the expected result from many of these configuration options. The presentation will focus heavily on the different hashing types and traffic control, especially the more advanced options such as Load-Based Teaming and Network I/O Control. Other areas of focus include physical separation of traffic, networks of differing security requirements such as DMZs, and suggested NIC configurations for both 1Gb and 10Gb environments. Finally, recommendations for physical switch configurations will also be covered. Throughout the session best practices, recommendations, and lessons learned from many production deployments will be shared. Attendees should expect to walk away with a deep understanding of the physical connectivity options available with vSphere, how they can be utilized in their environment, and the best methods for deploying them.

Thank you for your support!  We greatly appreciate it. Oh and yes, I’m a Detroit Lions and F1 Fan.

EMC VNX Fast Cache and Application Performance ; It’s not all Pancakes and Banana Sandwiches.

The issue we face as storage professionals is always going to be the age old question. “What I/O demand or pattern exists in your application?” This is a question that should always be asked. Sometimes application owners just don’t know what it is, sometimes we have to run with wild guesses and sometimes we can rely on our experience to determine the correct amount of drives, spindles, widgets and software to throw at an application to make it run correctly. Sometimes we get this wrong.

As my coworker, friend and colleague Joe Kelly @virtualtacit says:

It’s not all pancakes and banana sandwiches!

Varrow Madness Flashmob Video!

Shout out to Dance District for releasing this video from Varrow Madness a couple weeks back. We had a blast!

VMAX, vSphere 5.x and Zombie Space Reclamation!

We have quite the group of customers that are currently using vSphere 5.x, VMAX and Fast VP. In previous versions of ESXi we saw some weirdness when it came to dead space reclamation, movement of data and general misbehaving in vSphere 4.1 + Thin luns + FAST VP and a variety of other variables to include VAAI, Recoverpoint SAN Tap from a VMAX to an offsite CX3-80… Like I said a lot of variables.

After looking at FAST VP with our customer for almost a year now, a multitude of conversations with the best people at EMC and probably a few conversations w/ VMware our customer who prefers to remain nameless would like to share his ‘formulas’ with the greater good. You know who you are and next time I see you I owe both you and your boss a beer!

In short, vSphere + Dead Space reclamation is wierd. How VMAX and FAST VP presents it is also very difficult to report and see what is going on. This is why I call it Zombie Space Reclamation because you don’t really know if it is dead!

FAST VP (on Enginuity 5875.198 or higher) will work with VMware 5.x datastores that are defined as a tdev and not fully allocated. It will release space from the anchored tier when it is moved to another tier, but one must understand what values DO and DO NOT change.

1) Current Subscription percent value will NOT change in the anchored tier.
2) Allocated capacity will change in the anchored tier.
3) Total written capacity will NOT match Allocated capacity on the anchored tier.
4) Allocated capacity will be correct on the destination tier.

To correctly determine if FAST VP is working properly and if you have space available in the anchored tier (if you don’t want to oversubscribe), one can use the following formulas:

A person could use this formula to validate FAST VP is releasing space from the anchored tier, if Allocated Capacity equals what the VMAX is saying.
(Capacity of Anchored tier * Current Subscription % of Anchored tier) – Allocated Capacity of Destination tier related to devices using FAST VP and not anchored in the destination tier = Allocated Capacity of Anchored tier.

Capacity of Anchored tier – Allocated Capacity of Anchored tier = Available space on Anchored tier

And here is the biggest issue that we still see going on… in regards to VMAX +VMware ESXi and Storage Vmotion…

A dead space reclamation issue is only related to Storage vMotion when a virtual disk is deleted or migrated to a different datastore…and not releasing it’s space.

This is why I like to call it Zombie Space Reclamation…because you think the space is gone and possibly dead…but it still is there existing on a TDEV someplace and not being reclaimed.

Perhaps there should be a different way vMotion should be working?  Or how it reports back to the VMAX that it should be Zeros?  Time will tell.

**Disclaimer #1 VMAX FAST VP is still very much working well in customer’s environment but the strangeness in regards to how it behaves with VMware is an interesting topic.

**Disclaimer #2  This is not VNX FAST VP.

Madness, VMAX’s and a year’s gone by. Oh My.

It has been a year since the last time I posted about Varrow Madness back in 2011.  Since then quite a lot has changed in the form of my personal growth as an Engineer, growth of Varrow and all around ‘feel good goodness’.

Before I get into a few details, here are some highlights from last year that I like to brag about…in somewhat chronological order both personal and professional and what I feel like changed the direction my life took.

The most important thing is “Making a list and Checking it Twice”.  Normally reserved for Santa Claus, Continue reading
