Starting a career in storage domain. . .

Starting a career in storage domain can be very challenging and interesting. However, I believe that background in systems administration with extensive use of CLI can be very helpful. Being a storage admin you constantly need to work with the array software and CLI (for the core). Generally most array software’s are very user friendly and provides multiple wizards to achieve most common tasks. However, you soon find out that you need to know a lot about other things too. Such as you have to understand the Storage area network and work with a network administrator to configure zoning on SAN switches. OS on most of the arrays are based on Linux. Therefore Linux working knowledge is also required as I mentioned earlier systems administration experience comes handy. Last but not least whenever you are configuring arrays and provisioning storage to hosts you are doing so for some particular server or application. Most of the times you are allocating storage for email mailboxes and virtual machines. To perform such activities along with their respective administrators you too needs to understand the basis of email server and virtual desktop / application technology. Finally if you can read a lot and practice on your own, you definitely won’t face many problems.

EMCIE - EMC Implementation Engineer

 I recently got my EMCIE certificate. Here I like to share that EMC VNX Unified system is very powerful storage and ideal for mid to large size infrastructures. It supports Flash and SAS for performance and NL-SAS for capacity requirements. Besides many new features (FAST Cache, Improved UI) , one VNX feature which I like most is that it has DAE / BUS  numberings instead of LED lights, this helps tremendously while expanding storage enclosures.
To sit for EMCIE exam you have to prepare for both VNX block and File level. It will be very exciting to learn VNX as EMC provide lots of guides and even simulators to help understand its working. For Storage Administrators, I can recommend EMCSA exam, [EMC Storage Administrator].
You will also get a badge pin along with electronic certificate after passing the exam. One more thing the exam course will be revised after 31st December 2012, so plan it accordingly.
