Dr. Brain's - Gadgets of The Year for 2015

Hi Friends,

As the year winds down it's been another awesome year for gadget nuts like myself.  I thought I would share my thoughts on what I thought was cool for 2015.

The Apple Watch

Love it, hate it, confused by it, you've got to admit it, Apple did an awesome job promoting, advertising and building a really slick watch.  I'm an oddity, I actually like wearing a watch and always have, but most folks now-a-days see a watch as antiquated tech from a long gone era.  Bravo Apple for bringing back the watch!  I'm still amazed how many folks I see wearing these.

The Sphero BB-8 App Enabled Droid

The latest Star Wars movie comes out on Friday and this little guy is already a star!  Anything BB-8 seems to touch turns to gold!  You've got to hand it to Sphero, they did an AWESOME job on this little guy.  You control him from an application on your smart phone, so no need for an extra controller to put batteries in, lose, etc.


The iPhone 6S

Come on, are you really surprised?  Apple makes some of the sexiest phones on the planet!  Remember phones were just, well phones before the the iPhone.  Like the iPod before it, Apple turned a phone into something everybody has to have.  Let's be honest, how many people do you see with their heads down at a stoplight these days?  They may not be all on iPhones, but I bet a lot of them are!


Nintendo New 3DS XL

It's true, this came out before 2015 for Asia/Pacific, but the folks in America didn't get it until this year and if you could even get it!  People bought them up and cranked up the prices on for sale sites.  Yes it's pretty similar to the original 3DS, but with a faster processor, more RAM and that awesome second control stick, Nintendo released a real winner!


The  Patek Philippe Supercomplication or the $24,000,000 Pocket Watch

No, that's not a typo, that's 24 Million Dollars!!!  Yes it was made in 1933, but it sold at a Sotheby's auction in November of 2014 and it's SO cool, it HAD to make the list!!  This is NOT your Grandfather's pocket watch!  I took this part from Wiki:  "The timepiece contains 920 individual parts, with 430 screws, 110 wheels, 120 removable parts, and 70 jewels, all of them handcrafted on a tiny scale."  920 parts!!!


Fitbit Surge

Yep, another electronic watch thingy.  I really love this watch, I even got one for myself!  It's got the time, heart rate, GPS, timer/stopwatch, pedometer, rechargeable battery just to name a few options.  Yep, I'm still wearing mine and I still love it!


Hendo Hoverboard

This thing is SOOOOOOOO freaking cool!  Ever since I saw Michael J. Fox riding a hoverboard in Back To The Future Part 2 I wanted one of these.  You can't tell me you didn't want one of these!!

This was a Kickstarter project that got it's funding in December of 2014.  One of these days maybe we'll get one like Marty had.



Disney Tsum-Tsum

You've got to hand it to Disney, they know how to market their products!  My wife and sister love the Tsum-Tsum game and now there are stuffed and plastic animals, and all kinds of merchandise.  You can download the app from the iTunes and Google store.



Baby Dancing Groot

We first got a glimpse of dancing baby Groot in the Guardians of The Galaxy film and shortly after Funko released this awesome version!  I know it's not an electronic gadget, but I still think it's cool and I'm the one writing this article.  :-)


$50 Amazon Fire

A $50 dollar color tablet?!?!?  Okay, so it's not an Apple iPad Pro, but $50!!  A 7'' display, rear and front facing cameras and a quad-core processor.  I don't know about you, but that is pretty darn amazing!  Way to go Amazon!

Telsa Model S P85D

Yes, it's a car, but what a car!!!   Elon Musk and Tesla have truly built a technical marvel!  0-60 in 2.8 seconds, in Ludicrous mode no less!!!  But that speed doesn't compromise comfort or technology.  A HUGE bravo Telsa!


Amazon Locker

Absolutely brilliant!  According to wiki these were introduced around 2011, but my wife and I just started using these and I think they are AWESOME!  We've had a package taken from outside of our house before and it totally sucks.  Why people have to be such jerks I have no idea.  If you select a locker and your package fits at the specific location, the delivery folks will put it in the locker for you to pick up.  You get an email telling you your package is ready to be picked up and where.  You go to that location, put in your information and POOF the door opens and there's your package!!  Another Way to go Amazon!!


Did I forget anything that you thought was a super cool gizmo for 2015?  Disagree with my choices?  Let me know!!

Until Next Time

Nimble Storage - So Easy Even I Can Do It - Part Deux - Volumes, Initiators and Performance Policies

Hi Friends,

So last we left our array it was setup and ready to login.  Okay, great, now what?  The great thing is creating a volume and getting it visible to your consumers is super simple!

After you log into your Nimble array you'll be at the Home screen.  Lots of cool stuff there, but let's focus on creating our volume first.  Click on Manage > Volumes.
 

Now that we're in the Volume area, let's click on New Volume.  Yep, there's cool stuff on the left side too, I'll talk about that later as well.

Lots of new goodies!!  First we name our volume, give it a performance policy, choose if the data is encrypted, what iSCSI Initiator Group can access the data and if we're going to use CHAP or not.

Let's start with Performance Policy.  Applications are interesting things.  They tend to vary a lot, not just in what they do, but how they read and write data to disk.  The cool thing about the Nimble is you can select from a pre-defined list of popular applications or you can create your own performance policy!

Here's a list of the pre-defined policies and if you don't see your application here, you can either select "default" or you can create a policy to best match the performance characteristics of your application.

Here I've clicked on the New Performance Policy button.  Fist you name your new policy, select the block size your application best utilizes and whether or not you want to use compression and caching.  Compression and caching are usually on by default to give you great space savings and performance, but there are times when you don't need or want those features enabled.  More on that in another blog post.

Here I've called my volume "vol-creation1", given it a Performance Policy of "VMware ESX", Data Encryption is "Disabled", my iSCSI Initiator Group is set to group I've already created and I'm not using CHAP.  More on Encryption later!

Next we tell our Nimble what size our volume is going to be.  Here I'm selecting 2TB.  How about SPACE?  This is all about volume reserves, quotas, warnings, etc.  I'm going to take the defaults because they are pretty good as is.  If there's something you want to change, you can.

Lot's of good stuff here, so I'm going to break this up into two images.  First of all we're going to choose how we protect the volume.  You've got a lot of choices, none, use a pre-existing collection, create a new volume collection or protect the volume as standalone.  So what is a volume collection?  Basically you're creating a protection template that tells Nimble how you're going to protect the volume.  And the cool thing is you can re-use the template after you create it for other volumes.

The next step is to choose your synchronization.  You can select None, Microsoft VSS or VMware vCenter.  This is really cool because with Microsoft VSS you can have Nimble talk to your Microsoft application that supports VSS to do application consistent snapshots.  If you're using VMware, you can have vCenter create a VM consistent snapshot before you create your Nimble snapshot.

Now we're going to create a schedule for our template.  We can choose how often, when to start, on what days, how many snapshots to keep and if we want to replicate to another Nimble array.  Pretty neat huh?  More on replication later.

Okay, something new for our seasoned Nimble admins.  Notice the Performance piece in the workflow?  And notice we can click Next or Finish?  If you don't want to mess with advanced performance just click Finish, but I'm adventurous, so let's click Next!

Now this is really cool!  If you want Nimble to make the caching decisions, just leave this at Normal(default), BUT, if you're daring like me, you can choose to pin this volume.  So what does pinning do?  Say you want a particular volume to behave like a flash array.  You can select Pinned and the volume will not be evicted from cache when the data gets cold.

Remember, you've got a finite amount of cache in your array, so the more volumes you pin, the less cache you have for "regular" volumes.  CASL does a fantastic job swapping data in and out of cache, but sometimes you just need a bigger hammer!

So when would you need this?  One scenario I've been working on is putting your VDI gold image and replica on a single volume and pinning that to cache.  Create a small volume ~50g and pin the sucker!  It's a small size so it won't use a lot of cache, plus when you do a refresh or recompose, you're reading the two images directly from cache!

After you decide whether to pin or not, click Finish and you're done!!

Until Next Time!
