Hybrid or All-flash?

spinning-flash-hybridI’ve been seeing a lot of commentary of late (actually it’s been happening for a while, but now that we’re approaching VMworld, I guess I’m more conscious of it) about the value provided by hybrid storage systems from a cost perspective, while at the same time, the all-flash vendors out there are touting the storage efficiency features (they have to!) of their platforms, to get to a price point that run-of-the-mill customers can stomach, while providing very high performance.

There’s been lots of FUD about how the economics of hybrid systems will always be more cost effective when compared to all-flash systems. By contrast, the all-flash vendors will say that now, with the announcement of a flash device that is larger than the biggest hard disk, that all-flash will win out, once prices come down. Finally, a select few vendors are also saying that because they provide both hybrid and flash systems that they are (falsely) offering customer choice. I beg to differ.

How about a third option all-together, or if you will, no option at all.

What exactly do I mean by this???

Well, since the announcement of our 2.x release, Coho has been able to host both hybrid AND all-flash nodes within a single cluster, in a single namespace. Not only is this easier for the customer to set-up and manage, but a much better story from an economic perspective as well.

Consider the fact that, because we leverage software-defined networking together with software-defined storage, that we can firstly, start with a single 2-node cluster, unlike any of our competitors in scale-out, that must start with 4 or more. Second, the fact that we can place data in the appropriate tier of storage based on a per-workload view (we present as NFS today) of the flash utilization over time, and we make even more efficient use of the performance and capacity in the system, while simplifying it’s deployment for the customer. This means that if our analytical data indicates that you are running out of high performance flash, you can expand your system with an all-flash node OR if the analytical data says that you’ll run out of capacity while still maintaining the same level of performance, you can expand with a hybrid system. We take a data-centric view of the customers’ workloads, so that they are freed from making these choices; and we’ve found that the message of simplicity is resonating quite well, thank you!

Expand this to next generation flash media types such as NVDIMM, PCM, RRAM, MRAM, etc. and you can imagine why having MANY different types of flash memory in a single cluster, single namespace will become a must have feature.

Coho Data is on the path to deliver this today. Our platform was built with this in mind from the word “Go”.

It’s time to upgrade your thinking!

vExpert Webinar

It was great presenting last week’s vExpert Webinar along with my colleague Forbes Guthrie.

We did an overview of our scale-out technology, a deep dive on our integration with SDN and then spoke about the innovations we revealed at VMworld a couple months back.

For those of you who were not able to attend the webinar, you can watch it here. Enjoy!

TWiET #100 – Coho Data

If you missed Andy on today’s episode of TWiET (This Week in Enterprise Tech) you missed a lot. As promised, here’s an embed of the recording. Geek out with Andy on Web-scale, Flash, Horizontal scaling, Shared-nothing architecture, Software-defined, Cloud and on and on. It was a lot of fun listening live, but it’s always a treat when Andy’s on-stage!

Coho’s Andy Warfield on TWiT!

twit_logo

Andy Warfield, Coho Data‘s illustrious CTO and Co-Founder, will be appearing on the TWiT network’s This Week in Enterprise Tech (TWiET) podcast (episode #100… wow!) this coming Monday, July 21st at 2:30PM PST.

I have been an avid listener of TWiT since the very beginning so this is an especially big deal for not only me, but allows us to speak to a unique audience about how we’re defining the world of SDS and SDN.

Catch the live stream here on Mon or, you can find the playback here (once posted).

Thanks!
