It was with pride and pleasure – and with a delay of a week – that I read Wikibon’s announcement today: Wikibon is initiating ServerSAN as a new category, and defines ServerSAN along the lines of ScaleIO’s original design points from 2010.
As the only ServerSAN vendor with both software-only and bundled/appliance solutions in the market, we sure welcome some competition. Of course I second Stu’s view that competition increases both awareness and adoption.
The only part that I am really missing in Wikibon’s ServerSAN requirements is scalability. Nobody expects any “big bang” deployments – many customers like to start relatively small and then to grow big. However, one of the Dirty Little Secrets of ServerSAN (and any other tech) solutions is that if the product was not designed for scale from scratch, i.e. from day one, it will never really scale.
Enterprises have been consolidating their local datacenters into huge mega-datacenters. Service Providers host a rapidly increasing customer base, each with ever larger number of environments, in their datacenters.
Both enterprises and Service Providers today manage many tens of thousands of servers in their datacenters. Therefore, ServerSAN solutions that only scale to a few tens of nodes may be applicable for small businesses (if those small businesses prefer to manage their own computer-room over hosting their IT at a Service Provider), but cannot be regarded as serious alternatives for any Enterprise or Service Provider datacenter purposes.
After all, nobody expects any datacenter operators that manage thousands of servers to deploy multiple instances of a ServerSan product that scales to ten or twenty nodes only. The management overhead of such an exercise would defeat any potential operational or other gains… Hence Scalability is a big deal. Starting small is fine, and all products support that. Growing big, that is where the challenges lie.
There are several other Dirty Little Secrets of ServerSAN that customers should be aware of besides Scalability. Ensuring true Elasticity, achieving high Performance, Hardware Agnosticism, and the ability to run in hyper-converged architectures are examples of other core functionality that any self-respecting ServerSAN vendor should deliver. ScaleIO is providing today what Wikibon defines as Server SAN Phase 3.
Wikibon’s definition of ServerSAN as a category is an important step in enabling the growth of this space. I am sure, and hopeful, that many new vendors will enter our market in the coming years – offering customers more freedom and choice. ScaleIO’s customers have been enjoying the benefits of the ServerSAN category for the past 24 months. And we are not stopping here. We will continue to build on our strong technology, partner, and customer bases – as well as leverage EMC’s range of storage technologies and unmatched R&D budgets – to further increase our market lead, and to serve even more 100% satisfied customers worldwide.
