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.
