What is Protocols Engineering?

Our teams build the network interfaces our customers use to reach their data.   We are delivering future capabilities for new workloads such as Hadoop as well as scaling existing NAS workloads to huge levels and with non-disruptive operations to keep businesses running 24x7x365.  Our identity management technologies ensure that we can work in almost any environment and provide our customers with seamless integration to both directory services and storage protocols.

What is happening in Protocols Engineering?

Our customers have grown to expect success from Isilon, and now they want more – more scale, more storage, more uptime, more performance, more workloads – all to enable their business.

How do you build the Data Lake of tomorrow?   How to you integrate file and big data access without compromising the fidelity of the client protocols and APIs?   How do you actively balance new and existing client requests across an entire cluster to provide the highest level of service?  How do you build a single pool of storage that can meet all of the storage needs of a business?  These are the questions we answer daily, and to provide the solutions as quickly as possible, we are pursuing new ways accelerate the rate at which we can deliver value to our customers.

If software is eating the world, applications are ruling the world.  Our solutions integrate the OneFS infrastructure with the application ecosystems built on top of it.

How do we do our work?

We create a pipeline of work based on input from our customers, internal engineering needs, our product managers, and our strategic bets.  Our organization is “multi-threaded” in how we manage our engineering capacity and the throughput at which we deliver.   We aim to run a

lean organization to build the right things the right way at the right time.

What technologies do we use and build?

We strive to use the best tool for the job at hand.   We build our core infrastructure and network code in a combination of C and C++ with control functions leveraging the flexibility and rapid development provided by Python.  We use git as our source control system and leverage GitHub Enterprise based workflows for building and testing our code in a continuous integration model.  Creating internal clusters for testing and development is smooth and easy using on our automated builds and virtual deployments.

What kind of developer enjoys working in Protocols Engineering the most?

Our best engineers demonstrate curiosity and intellectual flexibility as they approach new problems.  Our engineering teams work in highly collaborative manners. We esteem developers that can help us ship product, are eager to learn and are willing to share that new knowledge with peers.   We listen to our customers and help them solve the problems that are ahead.
