New VMware Virtual SAN and Cohesity DataPlatform White Paper

CH-VSAN-LogoHot off of the press!: New VMware Virtual SAN and Cohesity white paper.

I got the opportunity to collaborate with my pals Gaetan Castelein and Sai Mukundan from Cohesity and co-author a white paper based on Virtual SAN and Cohesity DataPlaform. Download it and learn about the undeniable cost effective value hyper-convergence delivers to the modernization of data centers with Virtual SAN and Cohesity as primary and secondary storage solutions.

Here is a brief summary of the topics covered in the paper:

Capabilities offered by Virtual SAN and Cohesity DataPlatform


  • Pay as You Grow Scaling – Modular growth capabilities enable easy scaling on both Virtual SAN and Cohesity solutions so you only buy what you need when you need it. Simply add more storage when you need more high-performance primary storage, and add a single node or 2U block of 4 nodes to the Cohesity cluster when you need additional secondary storage capacity.
  • Plug and Play Installation & Policy driven Management – Both Virtual SAN and Cohesity are designed to be turnkey, eliminating the need for timely and expensive professional services. Both solutions leverage intuitive management consoles and offer non-disruptive upgrades. Once primary workloads are running on Virtual SAN, policies can be set up in minutes on the Cohesity Data Platform that leverages VMware native VADP APIs for data protection. The Cohesity solution dramatically lowers RPOs and RTOs.
  • App-Specific storage class of Service – While Virtual SAN is tuned to focus the fastest flash resources on your top tier applications, Cohesity follows up with application specific QoS policies for the backup services in your secondary storage. Combined, you are ensured that you are getting the best bang for your flash investment across your entire data center.
  • Fast RPOs and instantaneous RTOs – Cohesity provides sub-15 minute RPOs and instantaneous RTOs leveraging SnapTree zero-cost snapshots and clones. Cohesity also provides cluster-wide VM, file and object-level search for rapidly identifying recovery targets.
  • Data Reduction – Virtual SAN implements inline and post-process data reduction to enable effective storage reduction across a wide range of mixed workloads. Cohesity also o ers both inline and post-process dedupe and compression, configurable on a per workload basis.
  • Consolidation & Cost Savings – With intelligent use of flash in Virtual SAN and Cohesity, you can eliminate storage sprawl and consolidate your data onto the best in class all-flash tier and the most efficient hyperconverged secondary storage platform. The consolidation enabled by Virtual SAN and Cohesity’s approach will reduce datacenter footprint to achieve lower total cost of ownership. In addition, Cohesity offers native integration with all the leading cloud providers for data tiering and archival.
  • Support for backups, files, and test/dev copies – Cohesity complements Virtual SAN with support for backups, files, and test/dev copies. This further eliminates storage sprawl by eliminating NAS appliances specifically used for le serving or test/dev environments.
  • Accelerate application time to market – Cohesity makes secondary data productive. An instant, zero cost clone can be taken from a backup image, and presented to any Virtual SAN cluster for rapidly spinning up test/dev environments. Developers gain instant access for dynamic development, QA, and staging of their applications.
  • Built-in analytics – Cohesity automatically indexes all the content ingested into the system, enabling Google-like search to rapidly identify individual VMs or files. In addition, Cohesity provides detailed reporting on capacity and data utilization. Finally, the platform supports running MapReduce jobs directly on the platform for in-place, custom analytics on the data.

Hyper-Converged Primary & Secondary Storage: The Best of Both Worlds – Virtual SAN + Cohesity

CH-VSAN-LogoHyper-Convergence continues to push the evolution of the data center. The benefits and values introduced are undeniable as the results are visible on all spectrums of data center ranging from cost, operational efficiency, simplicity, risk reduction, performance, resiliency, scalability, and more.

The momentum and growth of Virtual SAN as a primary storage solution in the Hyper-Converged market is another undeniable fact. As the preferred primary Hyper-Converged storage solution for vSphere, Virtual SAN provides vSphere costumers a primary storage platform capable of satisfying the most demanding performance and availability requirements of any virtualized business critical application.

The principal values of Hyper-Convergence are now being expanded beyond primary storage solutions and onto secondary storage solution. Primary storage solutions are design to deliver data services and capabilities suitable for active applications and frequently accessible data. Whereas secondary storage solutions typically design to focus on cold/dark data.

The data services and capabilities of secondary platforms are focused around data management capabilities such as data archival, data protection, space efficiency, etc. Cohesity, a VMware eco-system partner has developed a Hyper-Converged secondary storage platform which complements the principals of Hyper-Convergence and Virtual SAN. Don’t miss an opportunity to learn all about it and see for yourself.

vSphere Virtual Volumes : Introducing SolidFire


Screen Shot 2016-06-02 at 9.03.45 AMSince the onset of Virtual Volumes the goal has been for storage providers to bring to life capabilities, automation and an evolution of storage consumption. Now it’s time for VVols Done Right.

Today during the company’s analyst day event, SolidFire announced their official support for Virtual Volumes with the release of their ElementOS (Version 9.0.0 Fluorine).

While working closely with some of the members of the SolidFire team such Keith Norbie, Josh Atwell, Andy Banta, Aaron Patten, Jeramiah Dooley and others, I got a chance to learn about the details of the SolidFire Virtual Volumes implementation.

From an implementation perspective, I think SolidFire has done a great job by not only by complying with all of the core implementation requirements of the Virtual Volumes framework. SolidFire is able to expand beyond the traditional capabilities used and found in the framework today and introduce a set of unique functions that has not been seen in current Virtual Volumes implementations until now!

SolidFire brings support for Virtual Volumes to vSphere customers with their Fluorine release:

Control Plane Compliance – Compliance with vSphere’s universal storage control plane and policy management framework. SolidFire/vSphere customers have the opportunity to transform their adverse storage management operations. Through the use of vSphere’s Storage Policy Based Management (SPBM), SolidFire allows customers to take legacy storage operating procedures and transform them into standardized and systematic procedures that are dynamically defined by the storage administrator for vSphere administrators.

Virtual SAN Availability Features and Capabilities in 20 Minutes

VSAN-AVAIL-LogoAs a follow-up to the Virtual SAN 6.2 space efficiency features and capabilities presentation, I shared last week from the “Virtual SAN Take 20 Webcast Series”, here is the second episode where I focused on the overall availability and capabilities features of Virtual SAN.

Remember that the information covered and demonstrated as part of these webcast series, applies to all Virtual SAN Ready Nodes, and the EMC/VCE VXRAIL engineered appliances that are powered by VMware’s Hyper-Converged software stack with Virtual SAN.

As a storage platform, Virtual SAN delivers enterprise-class availability that covers several areas of potential failures including software, hardware, and other potential infrastructure failures to satisfy the availability requirements of the most demanding business-critical applications.

In this episode, I cover the majority of the availability mechanisms in Virtual SAN including built-in and tunable failure tolerance, rack awareness, stretched cluster and replication capabilities. read more…
