Your Storage Career With EMC Certs
EMC offers certifications in enterprise storage, including tracks for data scientists, cloud (data center) architects, cloud administrators, as well as vendor-neutral options. Learn more about EMC's certifications and career paths for IT professionals.
EMC has been a market leader in the storage space for more than two decades. With such tenure comes a responsibility to train and certify storage engineers, developers, administrators and architects on the company's hardware and software. EMC accomplishes that goal through its Proven Professional certification program, and uses this program to maintain stringent training and certification requirements, as well as to provide a conduit for gathering valuable feedback from customers and IT professionals. Becoming a certified EMC Proven Professional allows direct input into EMC's product teams, so certification holders can affect the timing and feature-sets for EMC products and services.
EMC is so popular and successful that it comes as no surprise that the company has garnered the attention of various IT industry powerhouses. Currently, Dell plans to acquire EMC for $67 billion. There are bound to be changes at EMC once that acquisition is final, so credential seekers should check the EMC site frequently for potential updates to the EMC certification program.
EMC Certification Program Overview
Various specialization tracks exist within the Proven Professional program, allowing certificate holders to attain a depth of knowledge—which most EMC users cannot acquire—in specific areas of EMC products and storage technologies in general. Proven Professional tracks include data scientist, cloud architect, cloud and storage administrator, technology architect, engineer (cloud, platform and implementation), application developer and system administration. EMC also offers product-specific certifications for customers who utilize EMC ScaleIO, ViPR, Data Protection Advisor and XtremeIO storage solutions.
Most, but not all, Proven Professional tracks come in three levels: Associate, Specialist and Expert. The EMC certification process allows Proven Professionals to acquire experience and knowledge that can greatly assist in acquiring and flourishing in a storage-related job.
Each certification track in the Proven Professional program identifies a specific target audience. Current tracks that are open to any and all interested parties include the following:
Data Scientist (EMCDS)
Cloud Architect (EMCCA)
Cloud Administrator (EMCCAD)
Tracks geared towards EMC partners and customers include:
Storage Administrator (EMCSA)
Product/technology specific (ScaleIO Server-based SAN, ViPR Controller and Data Services, ViPR SRM Storage Resource Management, and Data Protection Advisor)
Tracks designed for partners only include the following:
Product/technology specific (XtremIO flash storage solutions)
Technology Architect (EMCTA)
Cloud Engineer (EMCCE)
Platform Engineer (EMCPE)
Implementation Engineer (EMCIE)
Prerequisites, pertinent technologies covered and additional specifics for each certification track and knowledge level are available on the Proven Professional website. Note that EMC provides free practice tests so that you can evaluate your readiness for each certification exam in advance. Of course, scoring a passing grade on the practice exam doesn't guarantee that you will pass the real exam, but relevant practice exams can indicate knowledge areas where you need more work prior to taking the real thing.
The following sections walk you through EMC certifications that are available to all interested parties and that don't focus on a particular technology. You'll also learn more about the job roles associated with each certification.

EMCSA: EMC Storage Administrator
If you are an EMC customer or partner and interested in storage, an excellent place to start the certification process is via the EMC Storage Administrator (EMCSA) certification. The EMCSA certification offers all three certification levels and completing the Associate Level certification requires you to pass just one exam, covering either information storage and management or backup recovery systems and architecture.
Although EMC recommends various instructor-led training (ILT), book-based training and online e-learning courses to prepare for passing each of these exams, there are no training or experiential prerequisites you must complete before taking the exams. Note that there are product-specific sub-tracks within the EMCSA certification, both at the Specialist and Expert levels.
Think about it: by passing a single storage exam, you can kick off your Proven Professional certification efforts and be well on your way to a better, more challenging job in the exciting world of storage technology!
Your First Job In Storage
With the lines continuing to blur between network, server and storage administrators, your first exposure to storage technology could well be in your current job. Software-defined networks and storage, cloud-based storage and virtual network overlays are all part of the movement towards virtualized storage systems. While storage area network (SAN) administrators have traditionally held jobs with a laser focus on physical storage strategies, the storage administrator of the future will have to know and understand physical and virtual storage, network and server technologies.
Now that infrastructure virtualization is settling into proven, production-ready technologies and techniques, storage administration must also move into storage/network/server administration rather than distinct disciplines for each area of expertise. As you proceed through the EMC storage certification process, be sure to pay close attention anytime the topic of virtualization appears. Virtualization of all types is profoundly impacting IT infrastructure, and storage virtualization is a huge part of that change.
EMCDSA: EMC Data Scientist Associate
The EMC Data Scientist Associate (EMCDSA) is a foundational certification that exposes you to the basics of big data and data analytics. Topics for this certification include an introduction to data analytics, characteristics of big data and the role of data scientists. Also covered are a variety of big data theories and methods, including linear regression, time-series analysis and decision trees. Various cutting-edge big data tools, such as Hadoop, "R" and PostgreSQL, are covered as aids to data analytics efforts.
EMC occasionally offers bundles of video ILT courses and an exam voucher at a significant discount, so be sure to check the EMC Proven Professional website before embarking on a new certification track.
Data Scientist, Business And Data Analyst Job Roles
The job role and description for data scientists is a fairly new development in the world of storage technology. Previously, storage analysts might have also been called "business analysts" or "data analysts," with distinct differences between the focus for each such role. IT business analysts are responsible for maintaining a business perspective on IT functions and operations, combining IT priorities with the business priorities of a company. Data analysts have traditionally focused on the technical aspects of storage and data management.
The data scientist role is a conglomeration of these two analyst roles: combining a strong technical background and understanding of data analytics with the acumen to recognize the impact of IT decisions on business operations. As you can see, a data scientist builds a bridge between the IT world and the business world, so that each side can appreciate concerns and input from the other. Think of data scientists as big-picture business leaders with a strong technical background in data analytics and management; in other words, they represent (and create) the best of both storage worlds.
EMCCA: EMC Cloud Architect
The EMC Cloud Architect (EMCCA) certification is your stepping stone from a storage administration or engineer role to becoming a full-fledged member of the storage elite. The EMCCA certification prepares storage specialists for migrating storage technology and applications to virtualized data centers or to the cloud. Data centers based purely on physical servers and infrastructure are quickly going the way of the dodo as virtualization technology transforms data centers into beehives of virtualization activity. EMCCAs help design virtual storage services and migration strategies as companies move from physical storage to virtual storage, or some mixture of the two.
EMCCAs learn generalized design consideration for virtualization of storage capabilities. The EMCCA certification is offered at all three knowledge levels and each level has its own specialization topic:
Associate: Cloud Infrastructure and Services
Specialist: Cloud Infrastructure Planning and Design
Expert: Cloud Services Planning and Design
The Cloud Architect Job Role
Cloud architects belong to the vanguard of storage architects that are leveraging their talents to virtualize storage infrastructure, as well as the underlying networks that support it. With cloud becoming the hottest of hot topics over the last few years, storage architects with an EMCCA certification will likely have a multitude of employment options available. From companies looking to migrate to a cloud storage design in their data centers, to cloud-based innovators such as Amazon Web Services, the cloud is doing more to automate IT infrastructure management and reduce costs than any single technology development over the last 20 years.
Many pundits worry that the software automation intrinsic in cloud environments will put various types of infrastructure administrators and engineers out of work. We believe there to be clear skies ahead for those who take the initiative to enhance their training and expertise with cloud technologies: those who successfully make the transition from storage administrator or engineer to cloud architect will remain in high demand for the foreseeable future. The reason that cloud has become such a popular buzzword is that cloud computing promises more resiliency at lower cost, with enhanced online data protection and disaster recovery capabilities thrown in for good measure. A strong business case for cloud technology makes the cloud architect a critical role for companies looking to move to a virtualized infrastructure.
EMCCAD: EMC Cloud Administrator
The EMC Cloud Administrator (EMCCAD) certification aims at professionals whose everyday work tasks involve the care and feeding of data center technologies. At the Associate level, an EMCCAD certification recognizes a solid foundation in data center infrastructure, storage systems and networking technologies, backup and replication, the cloud reference model, physical and virtual layers of a cloud environment, controls, services and management, and business continuity. At the Specialist level, a professional is expected to add capacity planning and management, process automation, multi-tenant management and chargebacks to his or her skillset.
EMCCAD certifications at the Associate level are fairly evergreen, applying to different vendor environments; the Specialist cert focuses on EMC and VMware technologies:
Associate: Cloud Infrastructure and Services (EMCCIS) and Information Storage and Management (EMCISA)
Specialist: Enterprise Hybrid Cloud Solutions - Federation
The Cloud Administrator Job Role
The duties of a cloud administrator are typically to install, operate and maintain the cloud infrastructure, often in a complex data center environment. At a more granular level, this often means developing and running workloads in a pooled compute environment that must be able to respond quickly to changes. This job role is often at the core of activity in a data center, interacting with software engineers, cloud architects and developers, and cloud product managers, and an administrator often needs good vendor relationship and negotiating skills to acquire necessary products.
Your Storage Career With EMC Certs
There are many moving parts to a company's storage strategy, and EMC's Proven Professional certifications are an excellent way to work your way into a great job in the storage arena. EMC's certifications are continuously updated and revised with the state-of-the-art storage management content, future-proofing your job skills and knowledge so that regardless of what new storage technologies become popular in the future, you'll always be on the cutting edge and in-demand.
From completing your first storage certification to achieving a data scientist or architect certification, each step in the Proven Professional program increases your knowledge, value and employment options in a competitive job market. The need for storage expertise will never recede and the sooner you start your certifications, the sooner you will begin to accrue the experience and expertise that can put you on a fast-track for success in storage management.

EMC Cloud Architect Certification – Training and Exam Experience
In February this year EMC introduced new certification track for Cloud Architects.
Cloud Architects deliver virtualization and cloud designs based on business strategies encompassing all key technical domains such as compute,storage, networking, applications, etc. EMC Proven Professional Cloud Architect (EMCCA) training and certification is designed to build required skill sets for experienced architects and consultants. The track has two levels. Virtualized Infrastructure (Specialist Level) and IT-as-a-Service (Expert Level).
Having pretty deep knowledge of virtualization (VMware Design certification VCAP-DCD) and IT service management (ITIL v3) I wanted to expand and formalize my education toward the cloud. As a holder of the basic EMC Information Storage Associate certification (EMC ISA) I was eligible to take the first step to the Specialist Level by taking the Virtualized Infrastructure Specialist Exam for Cloud Architects (">E20-018).
The curriculum describes the journey to the cloud (Virtualize -> Operationalize -> IT-as-a-Service) and concentrates on the second step of the journey; the design of cloud ready Virtual Data Center (VDC). Here is the list of course modules:
Virtualized Data Center and Cloud Overview
Virtual Data Center Architecture – Compute
Virtual Data Center Architecture – Networking
Virtual Data Center Architecture – Storage
VDC Architecture – Applications and Information
VDC Architecture – Business Continuity and Disaster Recovery
Designing for Virtualized and Cloud Environments
Governance, Risk and Compliance
Managing Virtualized Environments
EMC offers a practice test on the education.emcm website. It is very similar to the actual exam test and by taking it you can see very well where you stand with the knowledge related to the exam. Without any prior study I scored 73% which would mean a pass on the actual exam, however I saw some gaps in my knowledge in the non technical areas which lead me to decision to study more. There are no reading materials available other then taking the recommended course. Fortunately there is Video Instructor Led Training (VILT) option available. It contains the video of an actual class (over 22 hours) plus PDFs with the study guides. I think reading the PDFs would be enough to pass the test, but I found that watching the actual class was very informative – mainly the lab exercise parts which I really enjoyed where the instructor and students were weighting all the design options.
After the technological modules (2-6) come in my opinion the most interesting and enlightening topics 7 and 8: the Design and GRC (Governance, Risk and Compliance). The design methodology was very well described and explained on real life examples. The GRC concepts were quite new for me but still easy to understand. The module 9 – Management corresponds to ITIL and module 10 introduces the third phase of the Journey to the cloud.
My only problem with the VILT was that it contains some kind of copy protection and I was not able to play it on my corporate Windows 7 laptop and had to run it in clean Windows XP Workstation virtual machine.
It took me about three weeks of night studying, mostly enjoyable, concluded with Pearson VUE examination.
As I already wrote the actual test itself is not particularly hard and is very similar to the practice test. Sixty multiple choice questions must be answered in two hour time limit (as non English native speaker I got 30 minute extension), but I was done in less than an hour. With the passing score of 83% I am now an EMC certified Cloud Architect.
There are reports of shortage of cloud architects. This certification helps to demonstrate the expertise of being one.
How about them cloud architects?
I was on EMC training last week. To be more specific, I was on “Virtualized Data Center and Cloud Infrastructure” training, and took the “">E20-018 – Virtualized Infrastructure Specialist for Cloud Architects” afterwards.
First off, I passed the exam, which I’m happy about. Second, I’m still not sure how happy I am about the training and the exam itself.
When it comes to the training itself, we are talking about a week long, instructor led training. It covers several aspects of what would or could be considered elements of a virtualized data center, as well as cloud technologies.
You will start off with an overview of some of the definitions that make up cloud computing. A reference there is the definition of cloud, as it is defined by NIST. There is a reference the three service models of cloud computing, as well as the phases that you usually see when building a cloud infrastructure and the five key characteristics of a cloud delivery model.
You will also get an overview of the technologies that can be used to deliver a cloud like infrastructure. That includes stuff like different synchronization models, hypervisor types, link speeds (think of dark fibre as an example) and technologies used within a virtualized environment that range from a live migration, to the ability to offer services and service catalogs in a self service environment.
You also take a stab at things like governance, risk and compliance. You will get an idea of the things you can run in to when you create or even work with such an environment. You will references to things like the Sarbanes–Oxley Act, and business driven frameworks and best practices like ITIL.
Mix that up with some labs that focus on giving you food for thought when designing a cloud like infrastructure (there is no hands on in the labs, just paper and teamwork), and it sounds like you have a pretty decent training.
Or does it?
I have two main problems with the course itself. For one, I think that it’s based too much on the standards and concerns out of the US. I think that people absolutely need to be aware of things like the Sarbanes–Oxley act, but I also feel that models and concerns should be highlighted for companies that are not bound by this act. Or at least tell these people why the rationale for these acts might be useful to implement, besides the “you legally have to” way of explaining.
Don’t get me wrong, you need to consider these kinds of things, especially in a cloud like environment where you more quickly are able to cross global and legal boundaries, but then also focus on things that you might encounter outside of the United States.
The second concern is much harder to address, since one might get the feeling that you are not being taught anything new. And I think this is the much bigger issue. In a sense, anyone who has been working on the “* as a Service” environments will not really encounter anything new, and they might feel that EMC is just stating the obvious in their course. Techies that attend the training will probably leave with a feeling of “not enough examples and hands on, too much fluffy stuff”.
I think that they are partially right. For me it was a large part of what I have already encountered more than once. On the other hand, it’s good to see that people are working on standards, and the course itself brings together a lot of the things that you encounter, but might not knowingly consider. It’s “food for thought” if you will. And as with all such classes, you get a chance to exchange ideas and perspectives with your classmates, and that might be the most valuable thing about this class, especially with a topic that is harder to grasp (from an actual technology usedwhere do i start standpoint).
Read carefully! The biggest piece of advice I can give you, since sometimes the wording of the questions is just plain odd. Also, make sure you have an idea of the technology used in data centers, and virtualization across different tiers. Examples of the last one could be things like storage and network virtualization.
Spend some time on getting to know what governance, risk and compliance is all about. Have some sort of insight of what are the driving factors behind GRC.
The certification can be achieved, even without the training, but I feel the way some questions are asked is perhaps the biggest issue you can face in passing the exam if you already have some experience in designing or working in cloud like environments.
And let me wish you some good luck if you attempt to take he certification! One important note is that the EMC E20-001 is a mandatory prerequisite before attempting the certification, so make sure that you have that one if you want to be an EMC certified cloud architect.
