Condusiv Smashes the I/O Performance Gap with New V-locity 7.0, Diskeeper 18, and SSDkeeper 2.0

Condusiv is pleased to announce the release of V-locity® 7.0, Diskeeper® 18, and SSDkeeper 2.0 that smash the I/O Performance Gap on Windows servers and PCs as growing volumes of data continue to outpace the ability of underlying server and storage hardware to meet performance SLAs on mission critical workloads like MS-SQL.

The new 2018 editions of V-locity, Diskeeper, and SSDkeeper come with “no reboot” capabilities and enhanced reporting that offers a single pane view of all systems to show the exact benefit of I/O reduction software to each system in terms of number of noisy I/Os eliminated, percentage of read and write traffic offloaded from storage, and, most importantly, how much time is saved on each system as a result. It is also now easier than ever to quickly identify systems underperforming from a caching standpoint that could use more memory.

When a minimum of 30-40% I/O traffic from any Windows server is completely unnecessary, nothing but mere noise chewing up IOPS and throughput, it needs to be easy to see the exact levels of inefficiency on individual systems and what it means in terms of I/O reduction and “time saved” when Condusiv software is deployed to eliminate those inefficiencies. Since many customers choose to add a little more memory on key systems like MS-SQL to get even more from the software, it is now clearly evident what 50% or more reduction in I/O traffic actually means.

Our recent 4th annual I/O Performance Survey (no Condusiv customers included) found that MS-SQL performance problems are at their worst level in 4 years despite heavy investments in hardware infrastructure. 28% of mid-sized and large enterprises receive regular complaints from users regarding sluggish SQL-based applications. This is simply due to the growth of I/O outpacing the hardware stack’s ability to keep up. This is why it is more important than ever to consider I/O reduction software solutions that guarantee to solve performance issues instead of reactively throwing expensive new servers or storage at the problem.

Not only are the latest versions of V-locity, Diskeeper, and SSDkeeper easier to deploy and manage with “no reboot” capabilities, but reporting has been enhanced to enable administrators to quickly see the full value being provided to each system along with memory tuning recommendations for even more benefit.

A single pane view lists out all systems with associated workload data, memory data, and benefit data from I/O reduction software and lists systems as red, yellow, and green according to caching effectiveness to help administers quickly identify and prioritize systems that could use a little more memory to achieve a 50% or more reduction in I/O to storage.

Regarding the new “no reboot” capabilities, this is something that the engineering team has been attempting to crack for some time.  Per Rick Cadruvi, SVP, Engineering, “All storage filter drivers require a reboot, which is problematic for admins who manage software across thousands of servers. However, due to our extensive knowledge of Windows Kernel internals dating back to Windows NT 3.51, we were able to find a way to properly synchronize and handle the load/unload sequences of our driver transparently to other drivers in the storage stack so as not to require a reboot when deploying or updating Condusiv software.”

This means that customers who are currently on V-locity 5.3 and higher or Diskeeper 15 and higher are able to upgrade to the latest version without a reboot. Customers on older versions will have to uninstall, reboot, then install the new version.

"As much as Condusiv I/O reduction software has been a real benefit to our applications running across 2,500+ Windows servers, we are happy to see a no reboot version of the software released so it is now truly "Set It & Forget It"®. My team is happy they no longer have to wrestle down a reboot window for hundreds of servers in order to update or deploy Condusiv software," said Blake W. Smith, MSME, System Director, Enterprise Infrastructure, CHRISTUS Health.
