Startup intro: Reduxio

Duncan Epping · Sep 23, 2016 ·

About a year ago my attention was drawn to a storage startup called Reduxio, not because of what they were selling (they weren’t sharing much at that point though even) but because two friends joined them, Fred Nix and Wade O’Harrow (EMC / vSpecialist fame). I tried to set up a meeting back then and it didn’t happen for whatever reason and it slipped my mind completely. Before VMworld Fred asked me if I was interested in meeting up and we ended up having an hour long conversation at VMworld with Reduxio’s CTO Nir Peleg and Jacob Cherian who is the VP of Product. This week we followed up that conversation with a demo, we had an hour scheduled but the demo was done in 20 minutes… not because it wasn’t interesting, but because it was that simple and intuitive. So who is Reduxio and what do they have to offer?

Reduxio is a storage company which was founded in 2012 and backed by Seagate Technology, Intel Capital, JVP and Carmel Ventures. I probably shouldn’t say storage company as they are more positioning themselves as a data management company, which makes sense if you know their roadmap. For those who care, Reduxio has a head office in San Francisco and an R&D site in Israel. Today Reduxio offers a hybrid storage system. The system is called HX550 and is a dual controller (active/standby) solution which comes in a 2U form factor with 8 SSDs and 16 HDDs, of course connected over 10GbE, dual power supply which also includes a cache protection unit for power failures. Everything you would expect from a storage system I guess.

But the hardware specs are not what interested me. The features offered by the platform, or Reduxio’s TIME OS (as they call it) is what sets them apart from others. First of all, not surprisingly, the architecture revolves around flash. It is a tiering based architecture which provides in-memory deduplication and compression, this means that dedupe and compressions happens before data is stored on SSD or HDD. What I found interesting as well is that Reduxio expects IO to be random and all IO will go to SSD, however if it does detect sequential streams then the SSD is bypassed and the IO stream will go directly to HDD. This goes for both  reads and writes by the way. Also, they take proximity of the data in to account when IO moves between SSD and HDD, very smart as that ensures data moves efficiently. All of this by the way, is shown in the UI of course, including dedupe/compression results etc.

Now the interesting part is the “BackDating” feature Reduxio offers. Basically in their UI you can specify the retention time of data and automatically all volumes with the created policy will adhere to those retention times. You could compare it to snapshots, but Reduxio solved it differently. They asked themselves first what the outcome was a customer expected and then looked at how they could solve the problem, without taking existing implementations like snapshots in to account. In this case they added time as an attribute to a stored block. The screenshot below by the way shows how you can create BackDating policies and what you can set in terms of granularity. So “seconds” need to be saved for 6 hours in this example, hourly for 7 days and so on.

Big benefit is that as a result you can go to a volume and go back to a point in time and simply revert the volume to that point in time or create a clone from that volume for that point in time. This is also how the volume will be presented back to vSphere by the way, so you will have to re-signature it before you can access it. The screenshot below shows what the UI looks like, very straight forward, select a date / time or just use the slide if you need to go back seconds/minutes/hours.

What struck me when they demoed this by the way was how fast these volume clones were created. Jacob, who was driving the demo, explained that you need to look at their system as a database. They are not creating an actual volume, the cloned volume seen by the host is more the result of a query where the data set consists of volume, offset, reference and time. Just a virtual construct that points to data.

Oh and before I forget, just to keep things simple the UI also allows you to set a bookmark for a certain point in time so that it is easier to go back to that point using your own naming scheme. Talking about the UI, I think this is the thing that impressed me most, it is a simple concept, but allowing you to drag and drop widgets in to your front page dashboard is something I appreciate a lot. I may want to see different info on the frontpage than someone else, having the ability to change this is very welcome. The other thing about their UI, it doesn’t feel crammed. In most cases with enterprise systems we seem to have the habit of cramming as much as we can on a single page which then usually results in users not knowing where to start. Reduxio took a clean slate approach, what do we need and what don’t we need?

One other thing I liked was a feature they call StorSense. This is basically a SaaS based support infrastructure where analytics and an event database can help you prevent issues from occurring. When there is an error for instance the UI will inform you about the issue and also tells you how to mitigate it. Something which I felt was very useful as you don’t need to search an external KB system to figure out what is going on. Of course they also still offer traditional logging etc for those who prefer that.

That sounds cool right? So what’s the catch you may ask? Well there is one thing I feel is missing right now and that is replication. Or I should rather say the ability to sync data to different locations. Whether that is traditional sync replication or async replication or something in a different shape or form is to be seen. I am hoping they take a different approach again, as that is what Reduxio seems to be good at, coming up with interesting alternative ways for solving the same problem.

All in all they impressed me with what they have so far, and I didn’t even mention it, but they also have a vSphere plugin which allows for VM Level recovery. Hopefully we can expect support for VVols soon and some form of replication, just imagine how powerful that combination can be. Great work guys, and looking forward to hearing more in the future!

If you want to know more about them I encourage you to fill out their contact form so they can get back to you and give you a demo as I am sure you will appreciate it. (Or simply hit up someone like Fred Nix on twitter) Thanks Fred, Jacob and Nir for taking the time to have a chat!

Running your VSAN witness for a 2 node cluster on a 2 node cluster

Duncan Epping · Sep 20, 2016 ·

A week ago we had a discussion on twitter about a scenario which was talked about at VMworld. The scenario is one where you have two 2-node clusters and for each 2-node cluster the required Witness VM is running on the other. Let me show you what I mean to make it clear:

The Witness VM on Cluster A is the witness for Cluster B, and the Witness VM on Cluster B is the witness for Cluster A. As it stands today this is not a supported configuration out of the box. For ongoing support, it is required that users go through the RPQ process so VMware can validate the design. Please contact your VMware representative for more details.

A knowledge base article should be published on this topic soon, if and when it is published I will update this post and point to it.

@DuncanYB’s recommended reads part 5

Duncan Epping · Sep 18, 2016 ·

What a crazy week, VMworld. Many announcements by many different vendors and of course a kazillion blog posts. I picked a few which stood out to me and which are worth reading.

  • VMworld VMare Code hackathon to hit Barcelona 2016 by Alan Renouf
    The US version of the hackathon was a big success, and I expect nothing less in EMEA to be honest. Read Alan’s article to get a feeling / idea around what it was like and make sure to sign up if you have a good idea, or want to join an existing team!
  • VMware Virtual SAN 6.2 All NVMe Flash Array with Intel® SSD P3520 Sets New Record
    I just like reading these types of posts, what can a config like this lead to. Sometimes people say ‘well how realistic is the config?’ I actually have a customer deploying this exact configuration today.
  • Dell Technologies = Facemeltingly Awesome, but shall we talk frankly? by Chad Sakac
    A lengthy post on the Dell/EMC merger by Chad. He is in the middle of it and I always enjoy reading his thoughts.
  • VMware PowerCLI for Mac OS X, Linux & More? Yes, please! by William Lam
    Quick post on something very interesting, availability of PowerCLI on other operating systems then Microsoft. Leave a comment on his post if you are interested…
  • VMware ESXi Claimrules Unleashed by Guido Hagemann
    Want to know what a claimrule is all about? Guido broke it down in a nice way. Some good stuff in there.
  • Have got a couple of spare hours and want to watch some VMworld sessions, William Lam dumped everything in a long list, makes your life easier!
  • Julian Wood’s VMworld Day 1, Day 2, Day 3, Day 4 series.
    One of the best “personal takes” on VMworld US if you ask me. I know how much work it is to keep articles like these up to date. Some interesting thoughts, and I like how Julian included the parties, receptions but also a chat he had with PernixData’s Satyam Vaghani.
  • VSAN Availability series part 1, part 2 and part 3 by Jeff Hunter
    If you want to know more about VSAN and the availability aspects, this is a great series to read…

Going to VMworld and want to #GiveBack? Buy a shirt!

Duncan Epping · Sep 15, 2016 ·

Joe Baguley pointed me to something cool this week. An intern team in the UK has joined the Million Makers entrepreneurial fundraising challenge and will be selling cool shirts at VMworld of which proceeds will go to the Prince’s Trust.

The Prince’s Trust is a charity in the United Kingdom founded in 1976 by Charles, Prince of Wales to help young people aged 13 to 30 get into jobs, education and training. Many of the young people they help are in, or leaving, care, facing issues such as homelessness or mental health problems, or have been in trouble with the law. Their free programmes give young people the practical and financial support they need to stabilise their lives.

About the challenge, the Million Makers is an entrepreneurial fundraising challenge set by the trust which sees teams of employees from companies across the UK competing to raise at least £10,000 or more over a period of six months. The competition is a learning and development tool proven to build essential business skills and motivate your employees. Teams are invited to pitch their business plan in a Dragons’ Den-style panel of senior business leaders. Presentation skills are put to the test in order to secure £1,500 seed funding from The Prince’s Trust (this has already been secured).

How can you help? Below is the design of the shirt that will be sold through the VMworld store. The cost is going to be 20 Euro and there will only be 120 available at VMworld, so make sure you get one on day 1 as I suspect these will sell out fast, this is how you can GiveBack! I’ve been told that they will also be made available somehow online soon, so for those who are not going to VMworld there will be an option soon to buy one, I will let you folks know where I hear how/where/what. For now, make a mental note and pick one up!
