About Wipro Limited

Abstract The past few years have witnessed flurry of action and hype around Software Defined Storage (SDS). There are numerous vendors claiming to grind out SDS solutions and products every other week. The Technology is great and disruptive, but there are adoption barriers for end users. The intent of this white paper is to provide a perspective to the technology, benefits and challenges of adoption, and how and where System Integrator can fill the gaps and help the user in leveraging the best benefits of SDS.

Data: New Currency Of Today’s Business The storage required for exponentially growing data due to IoT, digitalization, social media, mobility etc., is in the range of about 40% to 60% per annum, as per industry reports and analysis. Based on this level of growth, storage capacities double every 18 months. For many datacenters the growth rate is in excess of 100% per year. Yet, only 65% of enterprise storage is effectively utilized. Before we discuss what Software Defined Storage is and how it is helping datacenter metamorphosis let’s look at the challenges of today’s storage world.

Traditional Storage Key Challenges in Storage World: • Managing Storage Growth • Proper Capacity Forecasting

In the past and in many datacenters now, legacy systems deliver storage through dedicated hardware devices. Configuration of these devices is done box by box. Troubleshooting is even more complex, requiring deep expertise in product architecture and that too different skill set for different vendor

configurations. Managing storage includes a mundane set of activities like

• Managing Complexity and Heterogeneity of Storage

• Required Storage Performance Can’t be Met in Current Scenario

vendors is needed to manage this complex infrastructure. Thus, traditional

• Vendor Lock-ins • Opex is Even More Than Capex • Lot of Manual Intervention Required for Storage Management

storage architectures are a vertically integrated stack of proprietary closed systems. These problems are driving end users to look outside their datacenters for an answer. Cloud technologies and services represent the fastest way for the business to reach new buyers.

SDS Use Cases

Backup Solution Transformation • Flexible solutions with deduplication at source and compression in target • Benefits: Lower Restoration and recovery time, scale out architecture

Automated and Policy Based Archive • Automation of archiving to cloud (Public/Private) storage • Benefits: Lower TCO, cheaper archive solutions like cloud, scale out architecture and seamless discovery

Disaster Recovery • SDS enables on demand and cost effective DR solution, leveraging all host based replicated workload and data at DR site • Benefits: DR as a service, DR site on SDS solution, lower TCO

TCO savings offered by SDS over traditional storage solutions in different stages of storage use is approximately given:

TCO Savings

~ 25% to 45%

IMPLEMENT

~ 6% to 8%

MANAGE

~ 15% to 35%

SDS Challenges SDS CHALLENGES Enterprise Readiness

SDS might be a good bet for greenfield projects, but introducing SDS in existing datacenters / brownfield projects requires detailed analysis

Integration

SDS offers capability to have integration with any vendor hardware, any monitoring, orchestration and cloud solutions, but integration is challenging and requires skills and knowledge on various vendors solutions

Different Interpretations

SDS has been interpreted by each vendor differently hence there is need to carefully look at vendor future SDS roadmap, architectural principals before finalizing any solution

Too Many Vendors

There are many vendors in SDS market with different offerings leading to confusion among end customers

Abstraction Not Attracting

Abstraction functionality may add more complexity due to the need of extensive compatibility testing and handling multi-vendor support for escalation and troubleshooting, thus adding to opex costs

Comprehensive Solution

Though there are many vendors with different solutions, but a comprehensive solution is still not available in today’s market

Management

Management challenges in defining the scope of control given to SDS controller

Lack of Cloud Economics

SDS though cheaper than traditional lacks granular and aggressive pricing offerings like cloud
