I/O Inefficiencies that Rob Performance

There are 2 severe I/O inefficiencies that cause performance and reliability problems.

First, is caused by the behavior of the Windows file system. It will tend to break up writes into separate storage I/Os and send each I/O packet down to the storage layer separately and this causes I/O characteristics that are much smaller, more fractured, more random than they need to be.

Second is storage IO contention, also known as the I/O Blender Effect, which happens when you have multiple systems all sharing the same storage resource, such as multiple VMs all sending small, random I/Os down through the same hypervisor.

Your performance is penalized twice by these storage I/O inefficiencies causing systems to process workloads about 50% slower than they should.

DymaxIO dynamically accelerates data for maximum I/O performance. By solving I/O inefficiencies at the source, DymaxIO improves application performance, increases throughput 30-40%, reduces latency, increases VDI capacity, reduces timeouts and crashes, shortens backups, improves data transfer rates and extends hardware lifecycles.

Proactive and Efficient Server Performance Optimization

DymaxIO contains thin file system drivers, that installs (no reboot required) on Windows VMs or physical servers and performs optimizations inline automatically while running transparently in the background with near-zero overhead to the server. What little CPU cycles are needed to run at lowest priority so as not to interfere with server operations in the event that CPU cycles are needed by other applications or processes.

DymaxIO contains a suite of patented technologies that optimize the Windows Storage I/O subsystem so that applications can get to and from the storage layer much faster and process a lot more data.

Some organizations may react to performance challenges by throwing expensive new hardware at the problem. Overbuying and overprovisioning for more IOPS or data throughput might mask the underlying problem for a while, but it does not solve the root cause of performance issues. The quickest, most inexpensive, and least disruptive approach to more performance is simply installing DymaxIO fast data software on all of your Windows systems and watching performance problems disappear.

DymaxIO Features

Whether on-premises or in the Cloud, DymaxIO contains a suite of patented technologies to accelerate your applications from VM or physical server to storage:


IntelliWrite is a patented write optimization technology that automatically prevents excessively small, fractured, random writes and reads that harms performance due to the severe inefficiency in the native hand-off of data between the Windows OS and underlying storage. IntelliWrite write I/O optimization technology prevents excessively small, fractured I/O characteristics in real-time by providing file size intelligence to Windows to help it choose the best allocation at the logical disk layer when writing files. This intelligence ensures large, clean contiguous writes and subsequent reads in which maximum payload is carried with every I/O operation to and from the OS to underlying storage. Without IntelliWrite, the Windows OS just opts for the next available address at the logical disk layer, which is rarely, if ever, the right size. This inefficiency causes many more I/O operations to occur to/from underlying storage for any given file that should be optimally written and read with a single I/O operation. Since DymaxIO reduces the number of I/Os for any given workload, there are even fewer I/O operations being mixed and randomized at the hypervisor or SAN level, which combats the ill-effects of the “I/O blender” effect.


IntelliMemory is a patented read I/O optimization technology that intelligently caches hot read requests from server memory that is otherwise idle and unused. IntelliMemory is a server-side DRAM read caching engine that dynamically leverages idle, available DRAM to target I/O that penalizes storage performance the most—small, random I/O. IntelliMemory’s behavioral analytics engine makes the best use of DRAM for caching by collecting usage data and I/O characteristics across a wide range of data points. By servicing I/O at the top of the technology stack from the fastest storage media possible, organizations reduce latency and further reduce the amount of I/O having to travel to storage, complementing the I/O reduction benefits from IntelliWrite.


InvisiTasking is a patented intelligent scheduling technology that allows all the DymaxIO “background” operations within the server to run with zero resource impact on current production by only leveraging idle CPU cycles and memory. Should other processes demand those resources, InvisiTasking ensures they are released without latency so there is never an issue of resource contention.

Benefit Reporting

The “time saved” dashboard demonstrates the value by showing the amount of I/O traffic offloaded from storage, the percentage of read and write I/O traffic offloaded, and the resulting time saved to any one system or group of systems. The Benefits tab shows “time saved” analytics such as Total I/Os Eliminated, Read I/Os Eliminated, Write I/Os Eliminated, Storage I/O Time Saved, Fragments Prevented and Eliminated, and Free Spaces Consolidated. The I/O Performance Monitoring tab reveals key performance metrics like IOPS, throughput and latency. It reveals the amount of workload processed on the local system for any given time period. It also provides important memory usage information like total physical memory and min/max/avg of available memory and how much of that was used for cache. This helps administrators fine tune memory allocations to get the most from the IntelliMemory DRAM caching engine. If there is not sufficient available DRAM, users are not getting the best performance possible from DymaxIO. The Analytics tab provides an hour-by-hour view for any time period to understand exactly what is happening on the local system related to key metrics like workload, read/write percentage, IOPS, throughput, I/O response time and benefits like write I/O reduction from IntelliWrite and read I/O reduction from IntelliMemory.

Required Memory: 3GB of physical memory per VM or physical server

Recommended Memory for Optimum Caching: 4GB of available physical memory per VM or physical server

If running on MS-SQL: add up to 16GB of DRAM for blazing results, then cap SQL memory usage leaving the additional memory leftover for the OS and DymaxIO. If no additional memory is available, cap SQL memory usage leaving 8GB for the OS and DymaxIO.

Recommendation: Optimum results will not be achieved unless (1) systems have adequate memory and (2) the software is installed on each VM on the same host. Since each Windows VM generates a minimum of 30-40% unnecessary I/O traffic, it is imperative to install DymaxIO on all the VMs on the same host. If installing on 10+ servers, simply request the centralized management console by contacting sales to push the software out to as many servers as desired.

What People are Saying

“Typically, IT professionals respond to application performance issues by reactively buying more hardware. Without the luxury of a padded budget, we needed to find a way to improve performance on the hardware infrastructure we already have. It saved us from having to make a heavy investment in SSDs or do a complete rip and replace of our entire hardware infrastructure. To this day, I still can’t believe software is doing this.”
R. Ortiz, IT Manager, ASL Marketing

“I have used Diskeeper since it was first introduced. It has always worked well in keeping my drive defragged for the fastest response times for all of my apps. Thank you again for this fine piece of software.”
Philip Baldwin, NVQB

“The Undelete software that we use on all our Regional Servers is undoubtedly worth every penny. It
has saved our Techs numerous hours in restoring files inadvertently deleted as opposed to having to
restore from backup tape.”
Michael Lucas, Gancom (Division of Gannet Fleming)

“Undelete saves backup restores when someone accidentally deletes a file from a Windows share. We store tapes off site so Undelete can save a big delay for file restores of that type. Undelete does what it says on the box – really – and it works nicely as a network recycle bin.”
Glenn Edwards, Infrastructure Analyst, Itron

“I have been using Diskeeper for many years, it is installed as a routine on all servers, networked clients, SHO and any other computer. It has never presented any problem and has always demonstrated improved drive performance in both servers and clients. With each new release Condusiv does not merely provide “window dressing”, they actually improve the product with the objective of making it easier to use, more reliable, more effective and easier to use.”
