Converged Infrastructures (CIs) and Reference Architectures like vBlock from VCE, VSPEX from EMC and FlexPod from NetApp have seen a lot of growth in the last few years. The growth did not come as a surprise to anyone given the perception around CIs solving some of the big IT pain points around Sizing, Architecting, Standardizing and Faster time to market.
The big benefit that Vendors promised with CIs was that it would reduce time required for making infrastructure ready to provide service by reducing or eliminating the time needed in various phases like Architect & Size, Detail Design, Deployment and Test.
But what was the real need for CIs and reference architectures?
Yes, you read it right – With Tintri you can reduce the number of Storage Best Practices to be followed for your Applications by 99%. Don’t believe me? Refer our Citrix XenDesktop Best practices documents as an example. There are five papers written by Rob Girard, an ex-Tintri customer who jumped over to Tintri to be a Tintri TME. He knows exactly what it means to be on both sides of the fence (give him a shout on Twitter).
Perhaps not and you don’t wear running shoes with your dress suit as well, unless you are a Justin Timberlake fan.
Usually we have at least 2-3 types of shoes (could be more and one may have more than one of each type). Each for what it is meant for and based on what type of foot we have. There is no shoe that works for all type of feet, one that we can use for running, for wearing with suits and for our casual wear. If at all there were one, it would compromise on all fronts and risk your health.
Well, this is not a fashion or health related blog. So you know where I am going from here….
Right from the day it was introduced by VMware at VMworld 2012, VSAN has attracted me with at least one thing – Simplicity. At that time, it was amazing to see the storage getting enabled in vCenter by just clicking a couple of check boxes. VSAN has seen its supporters and detractors but one thing that everyone agrees on is its simplicity.
This comes up a lot in my conversations with Customers, Prospects and Partners. Delivering 99% of the IO from Flash is one of the biggest differentiators for Tintri that allows us to maximize the value of Flash, delivering sub millisecond latencies to workloads.
One of the toughest jobs for any product that has both spinning disks and Flash is to keep the Flash filled with meaningful data in order to maximize the IO from Flash. This is something that the engineering teams really struggle with, resulting in products that deliver less than 50% IO from Flash in real life situations.
Tintri delivers this with the help of four key technologies –
Yes, we have been waiting for it for a long time now and we are still unsure about its whereabouts.
For those of you who want to understand why there is a need for VM awareness, there are a lot of blogs on this topic by some of the best in the industry. Stephen Foskett covered it in three parts – Part1, Part2, Part 3. Tintri has a great infographic explaining it on a page here and in a blog post here .
VVols is bringing in a new type of model which basically helps one define policies and data services at a VM level, getting granular than the current model used by traditional storage devices, which is at a Volume/LUN level and at the same time preventing the IO Blender situation to an extent.
In my opinion, adding VVols to vSphere is a great step by VMware but it is definitely only a small part of the solution. In fact, I think it is just an enabler and there is a lot that is needed at the underlying storage level to make it an ideal VM aware storage. Let’s dig more into this.
Yes, I have taken the plunge and I am on to a new challenge. I had a great ride at NetApp and I will cherish every moment I spent there, learning a lot which helped me grow both personally and professionally.
I think it is important to take on new challenges and adapt to changes because nothing ever stays the same, which means unless you can adapt and change too, you will be stuck doing the same things, which could then make your life a lot harder than it needs to be.
