Sometimes You Just Need New Equipment
For many years, I ran one of very modifiable LinkSys how routers w/wifi. I can’t remember the model number, but it’s the one that everyone loved to mod the firmware. It died sometime in 2011 (or early 2012) so I replaced it with a Netgear WNDR3700. It worked very well in the house I owned at the time. About the only quirk was I would have to power cycle it every few months. Things just stopped working and power cycling resolved the issue.
Fast forward to 2017 and I find myself in a new house. This one is single story so all my devices are further apart. The home office is towards the front of the house so signal strength to the back of the house is lackluster. Symptoms vary, but many apps on my phone or iPad would give me errors indicating that there is no internet connection even though there really is. To get around the issue, I bought one of those extenders. It works, but it is not ideal. It requires connecting to a different SSID as I move from the front of the house to the back (and vice-versa). If I forget to make the change, I quickly notice it because performance is very poor.
One day while cruising my local Costco, I noticed that they carried some of the newer Netgear routers so I decided to give it a try. After all, what’s the worst thing that can happen? Performance couldn’t get worse. To my surprise, it works great. Even when I forget to change SSID, performance is acceptable for most apps.
Setup is exactly the same as far as I can tell from the Advanced settings on both routers. Biggest difference is the updated processing capabilities of the new router. Even with a wired connection, everything just seems faster. I am going to guess processing WPA/WPA2, and the various other types of wireless encryption taxes many of the older processors and this newer router just handles it better.
If I go by the wifi strength indicators on my devices, nothing has improved. I still get the one bar (or two) if I don’t change to the appropriate SSID, but like I said earlier, performance is acceptable to most apps.
As the title of this post says, sometime you just need newer equipment.
How I Spent My Summer Vacation
OK, so I wasn’t really on vacation. But it sure felt like it at times. By some quirk of fate, I was able to attend both Cisco Live and VMworld this summer. And I had a blast at both of them.
I was at Cisco Live solely to work in VCE’s booth. For four days, I spent open to close talking to folks as they wandered the expo near the VCE booth. I got to meet existing customers, potential customers, co-workers, past co-workers from other places where I’ve worked, and more.
Since I work on the Product Management team, I tried to get people to tell me their stories. I wanted to know what their daily IT life was like, how was their infrastructure working for them, what were their plans for the near & long-terms. I heard some doozies in regards to plans, but I am not sure they are appropriate for a technology blog 😉
Anyway….I heard a lot of recurring themes: need to do more with less, need better management tools, need to learn about cloud, need to learn how to operate (or operate better) in a virtual world. Excuse me? The last one threw me a bit, but after a little more digging I found that some folks thought virtualization would solve their operational issues.
/soapbox on/
Folks, you’ve read this before on numerous other blogs but I am going to repeat it: if you have bad operational practices in the physical world and you don’t change them when you enter the virtual world, then you still have bad operational practices. Fix your bad practices before virtualizing. It will save you a lot of heartache and finger pointing. /soapbox off/
What I heard a lot of was, “Please help me”. There is just so much change going on in our industry now that it can be quite daunting to know what to do and where to go. Do I go cloud? Do I not go cloud? What is cloud? Can I have my own infrastructure? Can I just get my feet wet? All good questions and all that have the same answer: It depends. It’s usually at this point I would bring in one of our vArchitects to help me. I can answer most of the questions, but when someone asks me how many switches will I need, or how much capacity needs to be reserved for sparing, it’s best to leave it to the more knowledgeable folks.
My highlight of Cisco Live was when a customer came to the VCE booth with a friend and then proceeded to try to sell his friend a Vblock. It got so far as whiteboarding, drawing designs, and then some. A few vArchitects were listening in to clarify statements when needed, but pretty much just left them alone. The customer was doing an amazing job and was so enthusiastic about his Vblock he just had to get his friend to buy one (or at least into the concept).
It’s one thing for an employee to sell and be enthusiastic about products, it something else when a customer does it.
VMworld was a different story. I got to go as a mighty ATTENDEE (cue angels singing). I spent most of my time either in sessions or on the expo floor checking out all the other products. There is a lot of interesting work going on out there. I was surprised a few companies were still around from last year given that VMware entered their niche with some of the new features in vSphere 5.0. But after talking to them, the surprise went away. Some of these niche products do one thing, but they do it very well compared to VMware’s implementation and that keeps the customers coming to them.
As for sessions, I focused on vCloud Director and storage. I hit about 10 sessions covering the two topics. A lot for me to learn there. I was decently versed in the storage side of vSphere, but wanted a primer on the new storage features of vSphere 5.1. When it came to vCloud Director, I was fairly ignorant. I’m still ignorant on this topic, just less so. It’s definitely an area I want to learn more about. Time to cozy up with a book or two….
While at VMworld, I decided to run an experiment and wear my official VCE logoed shirt during the sessions. I wanted to see if people would stop me to ask questions. You now what? They did. In almost all the sessions I attended, at least one person came up to me with questions about VCE and Vblocks. There was one session where I had four people (non-related) stop me to answer questions.
So what did I come away with? 2 Kindle Fires, an Apple TV, and the VMworld plague. Been sick almost a week now. Awful stuff.
What else did I come away with? Some knowledge of vCD, some new friends, and a change in perspective on how VCE and Vblocks are viewed. Good times indeed.
My Friend Needs a Product From VCE
Disclosure: I work for VCE so make of it what you will.
I had lunch this weekend with a friend of mine that manages the server infrastructure for a local government entity. During the usual banter regarding business, he mentioned that a recent storage project (1+yr and still going) had suffered a series of setbacks due to outages, product compatibility issues, and other minor odds & ends.
The entity he worked at released an RFP that detailed quite a bit of what they were looking to accomplish, which in retrospect may have to been too ambitious given the budget available. After going through all the proposals, the list was narrowed down to two. On paper, both were excellent. All vendors were either Tier1 or Tier2 (defined by sales). Both proposals were heavily vetted with on-site visits to existing customers, reference phone calls, etc. Both proposals consisted of a storage back-end with copious amounts of software for replication, snapshotting, provisioning, heterogeneous storage virtualization, and more.
While each component vendor of the winning proposal was highly respected, the two together did not have a large installed base that mimicked the proposed configuration (combo of hardware & software). In hindsight, this should have been a big RED flag. What looked good on paper did not pan out in reality.
Procurement went smoothly and the equipment arrived on time. Installation went smoothly. It was during integration with the existing environment that things started to break down. The heterogeneous virtualization layer wasn’t quite as transparent as listed on paper. Turns out all the servers needed to have the storage unpresented and presented back. (Hmmm…first outage, albeit not a crash.)
Then servers starting having BSODs. A review by the vendors determined that new HBAs were needed. This was quite the surprise to my friend since the he provided all the tech info on the server & storage environment as part of the proposal and was told that all existing equipment was compatible with the proposal. (2nd, 3rd, 4th+ outages…crashes this time).
So HBAs were updated, drivers installed, and hopefully goodness would ensue. (planned outages galore).
Unfortunately, goodness would not last. Performance issues, random outages, and more. This is where it started to get nasty and the finger pointing began. My friend runs servers from Cisco (UCS) and HP. The storage software vendor started pointing at the server vendors. Then problems were attributed to both VMware and Microsoft. (more unplanned outages).
Then the two component vendors started pointing fingers at each other. Talk about partnership breakdown.
So what is my friend’s shop doing? They are buying some EMC and NetApp storage for their Tier 1 apps. Tier 2 and Tier 3 apps will remain on the problematic storage. They are also scaling back their ambitious goals since they can’t afford all the bells & whistles from either vendor. The reason they didn’t purchase EMC or NetApp in the first place was due to fiscal constraints. Those constraints still exist.
As I listened to the details, I realized that he really needed one of the Vblock ™ Infrastructure Platforms from VCE.
First, his shop already has the constituent products that make up the majority of a Vblock – Cisco UCS, EMC Storage (small amount), and vSphere. This makes transitioning to a Vblock ™ easier since less training is needed and a comfort level already exists for those products.
Second, the hardware and software components in the winning proposal were not widely deployed in the proposed configuration. At the time my friend’s shop put out the RFP, there were more Vblocks in production use in the United States than there were of the winning proposal’s configuration world-wide.
Third, at VCE, all the hardware/software components in a Vblock ™ are thoroughly tested together. It’s VCE’s job to find any problems so a customer doesn’t. People think that if you take three items listed on an HCL somewhere and put them together, then everything will work fine. It just isn’t true. In fact, a number of patches put out by the parent companies are the result of testing by VCE’s engineering and quality assurance teams.
And finally, probably the biggest reason why my friend needs a product from VCE is to get rid of all the finger pointing. When VCE sells a product, every component is supported by VCE. There is no saying “It’s not our problem, call the server vendor”, or “call the storage vendor”, or “call the software vendor”. I’m not saying that all vendors finger point. Also, your mileage with a set of particular vendors will vary, but if you are CIO/Manager/whatever, you have to admit that “one call, that’s all” is quite compelling. You can either have your staff spend time managing vendors or you can have your staff spend time moving your business forward.
I’ve put the bug in the ear of my friend about going Vblock in the future. It won’t happen any time soon since his procurement cycle isn’t conducive to purchasing all his infrastructure components in one fiscal year. It usually takes five years to get through all three major components. But who knows? Maybe his recent experiences will accelerate the cycle.

Book Review: Administering VMware Site Recovery Manager 5.0 by Mike Laverick
I’ve decided that I am going to review at least one book per quarter. Four book reviews per year are not that much when you consider that I probably read four books (various subjects) per month
.
So for my first book review of 2012, I am going to start with Administering VMware Site Recovery Manager 5.0 by Mike Laverick. Many of you already know Mike (the guy is everywhere) or are at least familiar with his blog (RTFM-ed).
Let me start out by saying that I did not like this book after first reading it. I felt that it was missing something; something that I couldn’t quite put my finger on. Then it hit me. Concepts are not necessarily discussed as concepts. Yes, there are one/two page discussions on concepts, but most often they are discussed as working knowledge. This should not have been a surprise to me because Mike clearly states (multiple times) that he expects his readers to have read the various manuals for detailed concept and background info on vSphere, Site Recovery Manager (SRM), your storage array, etc. He can’t teach everything needed to get SRM working so you have do some work on your own. In other words, RTFM. Once I came to grips with this, I re-evaluated the book in a new light and have decided that I like it.
As for the book itself, it has an interesting layout. You get a little bit of history concerning vSphere’s DR and HA features and what SRM is, and is not. Then comes a little detour into setting up a number of different storage arrays from Dell, EMC, HP, and NetApp. This detour does serve a purpose in that it sets a baseline storage configuration for installing and configuring SRM, albeit in the most simple configuration possible. It’s actually a smart move on his part because he is able to show how he setup his lab. It also prompts the reader to go check various items in order to ensure a successful install of SRM.
Then you get to the good stuff: installing, configuring, and using SRM. There are plenty of screenshots and step-by-step instructions for doing a lot of the configuration tasks. In fact, you could think of this book along the lines of a cookbook. Follow along and you should end up with a usable (in a lab) install of SRM.
It’s clear that after reading this book, Mike knows SRM. Peppered throughout the chapters are the various problems and errors he encountered as well as what he did to fix them. In a few cases, he does a mea culpa for not following his own advice of RTFM. If he had, a few problems would have been avoided.
Mike also hits home on a few simple truths. For those involved with Active Directory in the early days, there was a truth that went something like this: “The question is irrelevant, the answer is DNS”. In the case of SRM, substitute “Network and storage configuration” for “DNS”. So many problems that may be encountered are the result of a network or storage configuration issue. vSwitches need to be setup correctly, hosts need to see storage, vCenter needs to see hosts, etc.
I especially liked the bits of wisdom that he shares in regards to doing what I call “rookie maneuvers” (others call them stupid mistakes). For example, once you have SRM up and running, it’s too easy to hit the button without realizing what it all really entails. Mike warns you about this many times and prompts you to think about your actions ahead of time.
The later chapters of the book introduce customizations, scripting, more complex configurations, and how to reverse a failover. There is a lot going on here and worth re-reading a few times. A surprising amount of this info can be applied to basic disaster recovery principals regardless of whether or not SRM is in the picture.
Lastly, Mike walks you through upgrading from vSphere 4.1 to vSphere 5 and from SRM 4.1 to SRM 5. Upgrading vSphere may sound a bit odd, but not when you take into account that it’s required in order to upgrade SRM.
All-in-all, this book is a worthy read and should be in your library if your shop uses (or plans to use) SRM.
