Coho Site-to-Site Replication


Anyone that knows me well, knows that I have a unique history with Business Continuity and Disaster Recovery software as well as its practical use in business. In case you didn’t know, I used VMware SRM along with NetApp to recover from the 2011 Tōhoku earthquake and tsunami in Japan. In areas with natural disasters, it is becoming increasingly imperative but now also relatively common for companies to require or even demand their storage products support remote replication. Companies will use it either for a simple reason, such as shipping backups off-site or the more complex use case of disaster recovery, or both. It’s extremely convenient and easy to use when implemented properly.

That said, a common ask of us from customers here at Coho has been some form of site-to-site replication. We definitely didn’t design this as a “me too” feature. The technology has been built into the product since day one. We use synchronous replication instead of technologies like RAID to store redundant copies of data across the independent backend storage nodes. We leverage an asynchronous version of this for the remote replication feature. There was a lot of thought that went into the other components of our implementation to make it easy to use and enterprise fully-featured from the get-go.

Here are some of the key features of our replication release:

  • Asynchronous, periodic, snapshot-based replication
  • Active – Active site support
  • Virtual Machine granularity
  • Encryption
  • Compression
  • Bandwidth throttling
  • Simple UI with one-time setup and very easy configuration
  • Flexible replication schedule

* I’ll also add to this list that we’ll be introducing support for VMware’s SRM via a SRA (Storage Replication Adapter) in the very near future, so be on the lookout for information here and elsewhere on that.

If you’d like to read more details about the release, head over to the official Coho blog and read Doug Fallstrom’s (Sr. Director of Product Management) post on this topic.

Speaking from experience, site-to-site replication gives us another must-have enterprise grade feature, further solidifying Coho’s place at the cutting edge of new storage technologies… and this is only just the beginning!

Coho Data at Storage Field Day 6!


I am pleased to announce that Coho Data is participating in Storage Field Day 6 this Thursday morning 11/6 (from 8-10AM PST). Tech Field Day has special meaning for me, as it harkens back to the beginnings of my involvement in the greater technical influencer community. Leading up to my attendance at my first VMworld (2010), where I first met Stephen, and John Troyer, I started blogging and helped jump start what has become the Tokyo VMware User Group. Shortly following that, in early 2011 I got invited to attend Tech Field Day 5 in Silicon Valley as a delegate. I also attended Tech Field Day 6 in Boston. That was the 1st unofficial “virtualization” focused event which was a lot of fun. I have met many people and made good friends with several individuals from the Tech Field Day community, among others. That experience also helped open up the opportunity to present at VMworld regarding my experience during the 2011 Great Tohoku Earthquake and my 1st technical marketing job at NetApp (and my current position, for that matter).

I owe a lot to Stephen for the opportunity and am very much looking forward to helping Coho to host the delegates for the event later this week. I learned much of what I knew (at the time; before I joined the company) about Coho from the various events that they have done in the past, and I look forward to helping educate more and more influencers on what Coho has to offer with our market-differentiating, high- performance, web-scale storage solutions. I look forward to seeing you there as well!

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!
