Assessment of Storage Transformation for Virtual Environments


 

Objective:

Evaluate and Assess the Risks and benefits of emerging storage technologies to fit the needs of Virtual Environments.


 

Scenario:


 

Tradition Enterprise SAN Storage arrays have been a platform of choice for deploying Virtualization in the last decade.


 

These platforms are reaching their End-of-Life and are up for a refresh.


 

There is a latent need to transform storage environments into Software-Defined Storage Architecture to meet the new capacity, availability and performance needs.

Approach:


 

There Several approaches to Software-Defined Storage Architecture:


 

  1. Factory Built Convergence Platforms with VMware Converged Storage Stack (e.g. HP EVO:RAIL)
  2. Flash Virtualization Platforms(e.g. PernixData) - Extend the Life of traditional storage Server side flash to provide increased performance and capacity.
  3. Server Hardware with Bundle Storage Virtual Appliances (HP StorVirtual)
  4. Commodity Hardware with Converged Software (e.g.  Quanta)
  5. Purpose-Built Storage Appliances (e.g. Nutanix)

The following comparison will help you to protect your initial investment by assisting you to select the most suitable storage option for your firm.

We need to perform a detailed assessment to that best describe the condition of your storage infrastructure before you begin your storage transformation. Your may want to corroborate your assessment with our findings and decide on the final storage strategy.

ForeThought -- Global directory service for the Digital world

ForeThought Real world is full of people. We have phone books,yellow pages, maps and postal addresses to get to them. Real world is governed by laws, rules and norms. Digital world is full of devices and devices only(severs, desktops, appliances, gadgets etc..) In the digital world, We have DNS, IP Addresses/SMTP mail address, Routers/gateways. All of these methods are still rudimentery to lookup and locate attributes, features and functions of devices. Most devices serve a useful purpose. some of them are misused to inflict pain and damage in the digital world. Clear knowledge attributes, features and functions of devices can hel in reducing the risk and help us in responding to misuse of these devices. An idea of a Global Directory Service -- for locating Devices worldwide....These devices are attributed to People, Resources and Services.... This type of service can help in Asset tracking, Monitoring, Communications, Incident response, forensics and Da...

Information Infrastructure for Human Advancement - Vedic thought

Human Advancement is a far-cry when we are living in a world where human existence is threatened by man-made vulnerabilities. Human existence is threatened by Global warming - Natural disasters Health Crisis - Drinking water, Biodiversity/Genetically Modified Food, Virus Outbreaks Materials Crisis - Availability of Petroleum/Rare-earth for EV's (Lithium/Dyspersium) Security Crisis - Cyber Security/Data Breaches Global Political/Economic environment – Sanctions/Tariffs Purpose and Motivation Purpose of this conversation is to discuss the application of emerging technologies in information infrastructure for improving resilience of the human race and aspire for human advancement. This requires understanding key concepts of AI/Deep learning/Machine Learning, Nueromorphic computing and Pervasive computing in the context of  human interactions. There is need for a Multi-disciplinary approach involving Non-STEM and STEM(Science, Technology, Engineering and Math)...

Living a dream...five years of moving from services to lasting products.

RCV innovations has transformed from a training and consulting outfit to product based services organization.  The last five years had a see-saw effect on our existence as a viable business. We cannot forget the contributions of our mentors, early patrons and partners- Niranjan, Brad, Rakesh,Dorothy, Avik, Supriya, Sridhar, Bhaskar, Jaipal, Kishan, Joseph, Goutam, Mishra and many others. I am deeply moved by the faith some of our new customers have placed on us by adopting VAMANiT appliances for their business needs. Our team is grateful for the opportunity to serve you to the best of our ability. I am humbled by the commitment and excitement the team has shown in executing our new Nested Data center strategy. The pace at which we have trained ourselves in cutting-edge VMware vSAN and NSX technologies is noteworthy.  We are applying our VMware knowledge to Strategic and Mission critical applications by integrating energy efficient purpose built VAMANiT Nested Data ...
