Synerway promotes Enterprise CDP

Synerway (www.synerway.com), one of the top french backup vendors, continues to promote enterprise data protection with advanced CDP. I wrote 10 years ago a short blog post about them (blog post in French July 2006) and also in 2010 as the product was clearly oriented in the CDP direction at that time (blog post in French May 2010). The company, founded in France in 2002 by former Quadratec leaders, well known for Time Navigator, has shipped so far 15000+ appliances via a pure 100% channel model.



Synerway Enterprise CDP is a block based solution that captures in real-time data changes and ships them to a disk attached to a dedicated appliance. An agent must be installed to make this capture and of course, a first copy is needed that serves as a reference. The granularity is excellent as the capture can work from 512 bytes which is also a key optimization feature different from competitions who capture data from 1kB to 128kB. The product can manage up to 1000 snapshots, so 1000 versions possible, largely enough to control all data critical environments. There is no catalog and the agent fee is capacity based without any limits on the number of instances deployed. In the Windows environment, the agent is compatible with VSS. On the target, the product controls data and storage with thin provisioning, compression and encryption. There is a stress point as Synerway must develop, validate and follow various OSes with long matrices. Synerway also offered FileSafe and DiskSafe, 2 options from FalconStor.
It exists 3 approaches - In-Band, Out-of-Band and Side-Band - and this approach reminds me 2 Side-Band approach blog posts I wrote in Dec. 2005 (2 posts in French available here and here). In the classic Side-Band mode, it is used without any intrusive agent with just a logical volume manager and a dedicated path with an appliance that stores and versions data. For people who work in this industry for more than 10 years, this approach seems similar to what Revivio did, then the company got acquired by Symantec and offered the feature via NetBackup RealTime. You can check also a pretty blog post I made in January 2006, still in French.
Synerway seems to position Enterprise CDP in front of DeDuplication but these 2 technologies are more extension and not alternatives. Even with Compression on the Synerway side, users can perfectly use DeDup in target mode coupled with CDP. CDP targets RPO - Recovery Point Objectives - needs and its mission it's not to reduce storage space and DeDup is chosen for the storage capacity economy it can generate, or capability to use low network bandwidth for remote backup for instance. However, Synerway has a pretty interesting approach to both satisfy RPO requirements and storage space and their success proves that the solution has a real value.

Cohesity + Pure Storage, a clever couple

Cohesity (www.cohesity.com) and Pure Storage (www.purestorage.com | NYSE:PSTG), 2 leaders and innovators in data storage, just announced a partnership. In 2 words, Pure Storage with All-Flash Array line serves as primary storage of course and Cohesity C2000 harmonizes the secondary data landscape. One of the value users understand when they think about adopting these 2 solutions reside in the choice of something really new and not an extension or addition or something existent with classic vendors or at least classic product with new capabilities. Both of them use Flash + deduplication and contribute drastically to a low TCO by reducing footprint and energy while serving and protecting data better.


The solution is composed by 2 elements: a 3U Pure Storage FlashArray and a 2U Cohesity C2000 appliance and si pretty simple to integrate via VMware API, so finally each VM protection policy triggers a data flow towards the Cohesity device. Next step seems to be an integration based on Pure Storage snapshots mechanism to be stored directly on C2000 appliances. Both companies organizes a joint webcast soon to explain this deployment, you can easily register here.

Hortonworks introduces CDP

Hortonworks (www.hortonworks.com | NASD:HDP), leader in Hadoop and Big Data processing platform, continues to shake the market with a major announcement made yesterday in San Francisco. Hortonworks promotes its Connected Data Platforms aka CDP (not Continuous Data Protection) to offer best-in-class Data-at-Rest and Data-In-Motion processing. To deliver this promise, the company unveiled 2 new iterations:
  • Hortonworks Data Platform aka HDP, the historical product, today under release 2.4 which includes Apache Spark 1.6, Apache Ambari 2.2 and SmartSense 1.2. This is also the perfect opportunity to announce a new release approach with Core Apache Hadoop components (HDFS, MapReduce and YARN) and Apache Zookeeper to be updated annually and aligned with ODPi consortium and the Extended Services (Spark, Hive, HBase, Ambari....), running on top of the Core, top be released in a continuous manner.
  • and Hortonworks Data Flow aka HDF today in 1.2, leading real-time streaming data platform, key for IoT, now includes Apache Kafka and Apache Storm. HDF 1.2 will be available in Q1 2016.


Last key point of this major announcement, a strategic partnership with HPE to boost and optimize enterprise Spark performance. HPE makes a clear move in favor of Hortonworks as the preferred partner and solution for all big data environments and needs.
For the 4th time, Hortonworks will participate to the IT Press Tour in 2 weeks now and we'll learn more about these news. Great.

CDP v2, new iteration from Cohesity

Cohesity (www.cohesity.com), leader in the new Converged Secondary Storage landscape, moves fast and just announced a second generation of its CDP solution. This iteration targets data protection of course but also test/dev, file services and analytics. Thanks to its SnapTree technology, Cohesity enhances OASIS, the heart of the system, with some new capabilities:
  • Data throttling, QoS, Encryption AES 256 for data at-rest,
  • Site-to-site replication with 1-1, 1-N and N-1 modes,
  • A more comprehensive cloud archive function now supporting Amazon Glacier, Microsoft Azure and Google Nearline in addition to Amazon S3 and S3-based object storage system but also a tape extension,
  • SMB 2.x and 3.0
  • and AWB - Analytics WorkBench - to gain insights with pre-built AWB applications and possibility to build your own applications.
At the same tine, Cohesity adjusts the pricing of the solution now starting at $90k. The company accelerates and continues to promote a unified secondary storage platform with data processing and not a passive platform to just store data. Again, vendors who are just doing this will have rapid difficulties...

New Data Protection approach with Rubrik

Rubrik (www.rubrik.com), innovative startup dedicated to data protection, is one of the few vendors that recognizes that the secondary storage didn't really progress for at least a decade. In other words, does the industry really invent something since the Data Reduction wave with DeDuplication and Compression ? For sure we all remember some famous examples such Ocarina Networks (acquired by Dell in 2010), Data Domain (acq. by EMC in 2009 for $2.4B), Diligent (acq. by IBM in 2008 for $210M), Avamar (acq. by EMC in 2006 for $165M), Alacritus (acq. by NetApp in 2005 for $11M) or DataCenter Technologies (acq. by Veritas in 2005). But after that, nothing or just the dedup integrated a a feature to classic backup software or appliance. Done. I share Rubrik's view, classic products still exist but infrastructures now store more data with many different flavors of production environments, bare-metal or hypervisors based, and in many cases, use a legacy backup software is obsolete. You start a backup job but it can't finish because data sets are too big, too distributed, or application consistency is super tough to implement... in a few words, data protection need a new approach and Rubrik plays its role in that adventure.
Back to the genesis of Rubrik, the company was founded in 2014 by top engineers and leaders from Google, Facebook, VMware or Data Domain - Arvind Jain, Soham Mazumdar, Arvind Nithrakashyap - and Bipul Sinha, CEO and founder as well from Lightspeed Venture Partner. They have all in common that they understand the need, are motivated to change that landscape and know, a priori, how to build it. The company raised 2 rounds of money for a total of $51M, Series A was $10M by LSVP in March 2015 and Series B was $41M from LSVP and Greylock Ventures in May 2015. It's interesting to see also Mark Leslie, former CEO of Veritas Software, Frank Slootman, former CEO of Data Domain, and John W. Thompson former CEO of Symantec, who have made some significant investments to bootstrap the company. Rubrik is on a mission: To take out Backup software from the Enterprise. But to be serious, it's more than that, Backup is just a flavor of data protection and users, enterprises... don't really care about the product or the technology, in fact, what they need is an answer to their Data Protection challenge, just that. Historically, protect data was solved by backup software, but we all know that snapshot, versioning, cloning, replication, archival... are all data protection modes or flavors that all belong to the category. So now, you get the point, it's not about Backup, it's about Data Protection whatever is the (above) method used, users don't car, they care about their data. That's it. The notion always associated with data protection, at least it should be, is relates to RPO - Recovery Point Objectives - and RTO - Recovery Time Objectives - and to be serious, seen by users and applications not from the IT guy. RPO is essentially the quantity of data you accept to loose and this term refers to things before an event such a failure... This is perfectly illustrated with a daily backup job running everyday at 10pm, between jobs, nothing happens so IT accepts, if it doesn't do other things, to loose maximum 10 hours of work if we consider a failure just before the start a second job. RPO is key but for different applications and needs, you can consider different RPOs. A static web site backuped once a month or when changes occur is largely enough so in that case a RPO could be measured in days, weeks or months. For source code and development stuff, the company doesn't want to loose any good code written by its team, so a strict RPO is often in place. And finally imagine an activity with revenue, the RPO is also very strict. Now the RTO is different, if we reconsider these examples, we can imagine 3 different RTOs. As soon as you discover that your web site is down, you wish to recover and restart the site somewhere so in that case the RTO should be short. For development with no associated revenue, you can consider a flexible RTO in days or weeks and for the business transaction, of course the service must be protected with a very short RTO in mind. This RPO/RTO approach help everyone to map needs, requirements and the solution you need in each identified case.
So what is Rubrik about ? in a nutshell, Rubrik is about Converged Data Management, gathering together all flavors of data protection techniques in ONE product sold as an appliance to be easy to sell, to deploy, to use, to scale and to maintain. The expertise of Rubrik is in software but again to facilitate sales and the channel, an appliance model is perfect. The philosophy is to be non intrusive, there is no agent installed on VM or at the hypervisor level, the scalability is automatic, plug a new node and it will join the cluster. You receive a box and after 15 minutes the solution is running in production. To protection information just define a policy with SLA and run it.
The 2U appliance itself exists in 2 models, the R344 and the R348, with great resources in CPU, RAM, SSD, Network... and finally differ from the HDD capacity they offer: 48TB for the R344 and 96TB for the R348. Rubrik is an hybrid storage device as it includes SSD and HDD and you understand that each 2U chassis has 4 servers in it, it's the reason why things work by 4 in the spec sheet. The appliance exposes its storage via NFS or iSCSI and is managed through a REST API. In term of functions, Compression, Deduplication, Replication, Indexing, Snapshot, Encryption, Reporting, Super Granular Recovery... and a super easy and fast search mechanism (of course when we say indexing we implicitly associate search capability) are delivered by the system. For instance, a model like the R348 can easily managed 300 to 400 VMs. For long term data preservation, Rubrik relies on Amazon today and in the future Azure and Google but they don't offer by themselves a cold storage approach, Cold is Cloud for them. But you can also connected Rubrik to external object storage via S3 and even write to a NFS store. Also today the product is limited to VMware (vSphere 5.1, 5.5 and 6.0) but the market is so large that the limitation is more an advantage to stay focus. The model is 100% channel and start at $100k. The solution is superb, honestly, it's good to see people who have designed a radical new solution and solved the problem differently in favor of simplification. Success will come naturally when you have such product, it's just a term of execution but leaders pay attention to that. The product will flood the market, no doubt. Interesting to see that Cohesity and Rubrik share some ideas and participate to the revolution of secondary storage.

Cohesity to change storage positions

Cohesity (www.cohesity.com), leader in the new wave of unification of secondary storage, announced recently their first product iteration. The session during The IT Press Tour last week helped all of us to dig and understand better the strategy and the product while feeling the atmosphere in their office. And we had the privilege to speak with Mohit Aron the CEO and founder of the company, who already founded Nutanix, an other famous shop. In term of company finance situation, Cohesity closed 2 rounds - A at $15M led by Sequoia and Wing Venture Capital in November 2013 and B at $55M led by Artis Ventures and Qualcomm Ventures with Accel, Battery, Google and Trinity in June 2015. Wow, all this to accelerate the development and the market penetration. The total raised is now $70M but it's interesting to see the number of VC "motivated" by this project. Cohesity seems to be Hyper Compelling.
I already covered Cohesity very shortly as we didn't have lot of infos, it was in September 2014, just a few months after they got created, and you can read the short blog post here. You can even discover the previous logo.


So what is Cohesity all about ? What are the challenges they wish to solve and how the solution works ?
The first element is to consider that the biggest volume of data are stored on secondary storage, meaning by storage not operating for the business directly such backup images, archive data sets, copies (replication, snapshots, clones...) for DR... but all this, again, represents the largest bulk of data. These data that represent the business at a moment of time - pretty frequent for snapshot and less frequent with classic copies - are also not at all mined or analyzed but everything is there. Again, around 80% of corporate data sit in secondary storage. So the idea of Mohit Aron was and is still to offer in one data platform all the data workflows associated with data protection - backup, archive, snapshot, clones, replication, DR... - but also development and analytics. They call it the Cohesity Data Platform, perfect on this blog that historically was started at the age of CDP (Continuous Data Protection).
In term of product, Cohesity develops software but sells appliance, the C2000 line, to continue in the idea of simplicity. Physically the CDP is a 2U chassis with 4 nodes and users can start with 3 nodes. 2 models exist: C2300 and C2500 with respectively 48TB HDD and 3.2TB PCIe SSD and 96TB HDD and 6.4TB PCIe SSD and both have 8 10GbE ports - 2 ports per node. Cohesity builds 3 software layers: OASIS (Open Architecture for Scalable Intelligent Storage), Storage Services and an Application Environment. The product is managed via a very intuitive GUI and CLI and can be integrated with a REST API. With a strong DNA in distributed software and in particular file system, the team develops SnapFS, a shared-nothing strongly consistent distributed file system that span every node, that represents the core of the solution.

For data services, Cohesity provides snapshots & clones, global deduplication (inline and post with 8-16KB granularity), replication (tunable but by default 2 copies), auto-tiering in both directions (SSD <-> HDD) and non disruptive operations. Erasure Coding will be ready in 2016. Analytics is one of the key value of the platform and things like indexed backups, search capabilities and reports complete the picture. Above, Cohesity expose SnapFS via different protocols such distributed NFSv3, a RESTful API and of course the ability to connect to VMware instances via VADP. SMB, iSCSI and HDFS will be offered laer. The solution is of course infinitely scalable, will receive more and more features soon, and is today positioned as a mid-market environment with VMware and is priced below $100K. In fact many primary storage vendor could dream about these features set. Cohesity really changes the landscape of Data Protection and participate to the new adventure of Converged Secondary Storage with players like Rubrik. It's no more just storing data it's about storing and processing data on the same platform.
