ESG Labs Validates Results of Condusiv’s V-locity I/O Reduction Software Reducing up to 50% I/O Across 3,450 Virtual Servers


Leading Analyst Firm Uncovers Never-Before-Seen Results of V-locity® I/O Reduction Software from 3,450 VMs that Evaluated V-locity at over 100 Sites on Real-world Production Workloads

Condusiv® Technologies, the world leader in software-only storage performance solutions for virtual and physical server environments, today announced the findings from ESG Labs that validates the before/after performance results of V-locity® I/O reduction software, based on an independent audit of data that was collected from 3,450 systems evaluating the software at over 100 sites. ESG’s audit, which measured the achieved performance benefits of V-locity from virtual server to storage, found that Condusiv’s I/O reduction software leads to significant storage performance improvements without the need to purchase additional hardware. 

In addition to revealing results of the audit, the ESG Lab Review, authored by ESG Lab Analyst Mike Leone, helps organizations understand the benefits of I/O optimization for their environment. The report also highlights the problem of I/O inefficiencies in virtual environments and shows how V-locity solves them. In summarizing why the performance improvements with V-locity are so important to today’s organizations, Leone wrote in the Lab Review: "Performance is a critical concern when a mix of mission-critical applications share the same host as well as the same underlying storage. This is especially troublesome in Windows environments, where over time, write inefficiencies lead to loss of throughput and generate an IOPS inflation." 

The ESG Lab Analysis found that V-locity: 

  • Reduced read I/O to storage. ESG Lab calculated 55% of systems saw a reduction of 50% in the number of read I/Os that get serviced by the underlying storage, and 27% of systems saw a 90% or more reduction in read I/Os.
  • Reduced write I/O to storage. As a result of I/O density increases, ESG Lab witnessed a 33% reduction in write I/Os across 27% of the systems. In addition, 14% of systems experienced a 50% or greater reduction in Write I/O from VM to storage.
  • Decreased I/O response time. ESG Lab calculated the total time required to process all requests for each system and concluded that on average, systems with 3GB of DRAM achieved a 40% reduction in response time.
  • Increased throughput. ESG Lab witnessed throughput performance improvements of 50% or more for 43% of systems, while 29% of systems experienced a 100% increase in throughput, and as much as 300% increased levels of throughput for 8% of systems.
  • Increased IOPS from DRAM. ESG Lab found that 25% of systems saw IOPS increase by 50%, and a small group of 25 systems achieved a 1000% IOPS improvement.

ESG’s audit validated that V-locity’s patented IntelliWrite® component eliminated small, fractured I/Os with more contiguous writes, which also reduced randomization and noise from the "I/O Blender effect." Meanwhile, V-locity’s other patented engine, IntelliMemory®, allowed for a high percentage of audited systems to leverage available DRAM as Tier 0 for their caching strategy. 

Based on these impressive results, Leone stated in the report: "ESG Lab validated that V-locity software optimizes read and write I/O for physical and virtual Windows systems that consistently demand high levels of storage performance. Leone concluded: "This combination led to a significant reduction in both read and write I/Os to the underlying storage, an increase in IOPS and throughput by more efficiently utilizing DRAM, and overall application performance improvements by reducing latency by an average of 40%." 

"ESG’s independent audit and review of V-locity results against production workloads validates the largest test of its kind to measure and validate that Condusiv’s I/O reduction software is the ultimate complement to any virtualized infrastructure to boost critical application performance," said Brian Morin, Condusiv’s Senior Vice President of Marketing.

The ESG Lab Review concludes: "The last thing IT organizations want to do is spend more money on additional hardware to hopefully improve their storage performance and operational efficiency for the immediate future. It takes time to pick the right technology, vet it, deploy it into production, and then start seeing the benefits. A free evaluation of V-locity from Condusiv Technologies can prove that an easy-to-deploy, non-disruptive software solution can drastically improve application performance without the added cost or complexity of more hardware."

"We have been educating the market on the two big I/O inefficiencies in virtual environments that’s akin to pouring molasses on systems, penalizing performance with death by a thousand cuts due to an I/O profile that’s much smaller, more fractured, and more random than it needs to be," added Morin. "This report validates the extent of that penalty and what users can expect from V-locity to solve the root cause of performance issues for 50-300% faster application performance without adding new hardware."
