What ViPR SRM Can Show You About a VPLEX Environment

VPLEX is EMC’s premier storage virtualization solution. While VPLEX greatly simplifies everyday storage management, storage virtualization has presented storage administrators with new challenges in areas such as reporting, performance troubleshooting and chargeback. In ViPR SRM, new capabilities enable you to peer under the virtualization layer to understand what’s actually going on in a virtualized environment. In a VPLEX environment, ViPR SRM enables a storage administrator to understand how storage capacity is being used, and who is using it to understand end-to-end relationships from host to storage and to verify that VPLEX is configured according to best practices.

For example, a challenge for a storage administrator is to understand, overall, how storage is being used - how much for traditional block or file, how much is virtualized, how much is free, and so forth. New to ViPR SRM, a unified enterprise capacity dashboard shows total storage capacity for the environment in one place, and how it is used. The dashboard includes a view of usable capacity (top middle view), with a bar indicating how much is used for virtual storage. Note that the virtual storage is actually based on physical block storage; so ViPR SRM carefully ensures that this block storage is not counted twice in the enterprise dashboard.

Predictability and Probability with the ECS Appliance

You may not know it, but life on earth almost came to an end back in early May. The HL129 asteroid came within 200,000 miles of the earth, which is closer than the distance to the moon. Ok, so earth may not have had a chance to get obliterated. But that got me thinking about the idea of predictability and probability of success, especially when it comes to running ViPR Services on commodity hardware.

In September 2013, EMC announced Project Nile, which officially became the ECS Appliance during the last EMC World in Las Vegas. One of the primary goals of the ECS Appliance is to run intelligent software on commodity hardware. This stack is designed to support running Object, HDFS, and Block services on hardware for massive global scale-out platforms. Combined with a single global namespace and an intuitive self-service portal capability, customers are able to build out a true private cloud solution within the Enterprise, or even enable public Service Providers to provide their own ECS-based cloud service.

“Analyze This”: How Analytics, Pattern Recognition and Software-Defined Storage are Transforming the Datacenter…and Your Life

Pattern recognition! That’s what we carbon-based ‘humanoids’ are good at…since the very beginning when humankind first started walking upright. As a whole, we’re really adept at observing our immediate surroundings, natural environment and a sundry of other random and not so random things. We notice what happens around us in our personal biosphere, and existential universe. We notice things that touch our lives in some significant or insignificant way. From the mundane and annoyingly trivial to profoundly grave matters affecting our very existence like: Cause/effect; action/reaction; commotion/notion; fascinations/machinations; observation/correlation; discovery/recovery; monitoring/manipulating, detection/correction; measuring/tabulating; analyzing/theorizing and so on. My, how busy we are! A strong survival and pain avoidance instinct does that. And so does natural selection.

It comes down to situational awareness (SA). SA gleaned from recognizing patterns that allows us to understand interrelationships and dynamics so we can plan for; act on and hopefully accurately predict events, occurrences and outcomes. Of course, sound ‘policies’ usually evolve, improve and get codified in the process. Just think about how much you observe in your daily life. Chances are you’re constantly coming up with possible ‘situations’, course of actions (COAs) and maybe even personal policies based on probabilities or predictability for all different reasons, seasons, ligations, occasions and outcomes. And we tend to make these ‘root cause’ observations, COAs and predictions on both general abstracted assumptions and/or backed by granular data analysis. We can even ‘virtualize’ scenarios and problem solving while day dreaming….or conjuring up ‘what ifs’.

Data and the Path Best Traveled

You’ve spent a lot of time and money to deliver the best application performance and availability to the business. Your efforts have included investments in the latest technology regarding storage arrays, servers, and switches. This has all been required to deliver a powerful virtual environment that will handle the needs of the business now and with an eye towards the future. You are confident that scaling to thousands of virtual machines per server won’t be an issue. But the question remains, “Is my environments capability being maximized”?

What is I/O Multipath Management…..Why Should I Care?
I/O multipathing is the ability to manage, load balance, and queue up multiple I/O paths in both physical and virtual environments. The problem faced especially with virtual environments is that as the rate of consolidation grows, the efficiency of path management affects both performance and ultimately application availability. Think of your I/O multipath management software as the “traffic cop” that is constantly directing I/O and balancing loads to and from hosts, switches and SAN’s. This job is especially critical in virtualized environments running intensive OLTP (Online Transaction Processing) applications such as SQL Server, Oracle, Virtual Desktop, and Cloud Services. As you add more virtual machines, native multipathing applications have difficulty scaling and this often manifests as latency or outages in the field.
