The Revolution of Our Technology

by Rick Cadruvi, Chief Architect 18. October 2017 12:38

I chose to use the word “Revolution” instead of “Evolution” because, with all due modesty, our patented technology has been more a series of leaps to stay ahead of performance-crushing bottlenecks. After all, our company purpose as stated by our Founder, Craig Jensen, is:

“The purpose of our company is to provide computer technology that enormously increases

the production and income of an area.”

We have always been about improving your production. We know your systems are not about having really cool hardware but rather about maximizing your organization’s production. Our passion has been about eliminating the stops, slows and stalls to your application performance and instead, to jack up that performance and give you headroom for expansion. Now, most of you know us by our reputation for Diskeeper®. What you probably don’t know about us is our leadership in system performance software.

We’ve been at this for 35 years with a laser focus. As an example, for years hard drives were the common storage technology and they were slow and limited in size, so we invented numerous File System Optimization technologies such as Defragmentation, I-FAAST®1 and Directory Consolidation to remove the barriers to getting at data quickly. As drive sizes grew, we added new technologies and jettisoned those that no longer gave bang for the buck. Technologies like InvisiTasking® were invented to help maximize overall system performance, while removing bottlenecks.

As SSDs began to emerge, we worked with several OEMs to take advantage of SSDs to dramatically reduce data access times as well as reducing the time it took to boot systems and resume from hibernate. We created technologies to improve SSD longevity and even worked with manufacturers on hybrid drives, providing hinting information, so their drive performance and endurance would be world class.

As storage arrays were emerging we created technologies to allow them to better utilize storage resources and pre-stage space for future use. We also created technologies targeting performance issues related to file system inefficiencies without negatively affecting storage array technologies like snapshots.

When virtualization was emerging, we could see the coming VM resource contention issues that would materialize. We used that insight to create file system optimization technologies to deal with those issues before anyone coined the phrase “I/O Blender Effect”.

We have been doing caching for a very long time2. We have always targeted removal of the I/Os that get in your applications path to data along with satisfying the data from cache that delivers performance improvements of 50-300% or more. Our goal was not caching your application specific data, but rather to make sure your application could access its data much faster. That’s why our unique caching technology has been used by leading OEMs.

Our RAM-based caching solutions include dynamic memory allocation schemes to use resources that would otherwise be idle to maximize overall system performance. When you need those resources, we give them back. When they are idle, we make use of them without your having to adjust anything for the best achievable performance. “Set It and Forget It®” is our trademark for good reason.

We know that staying ahead of the problems you face now, with a clear understanding of what will limit your production in 3 to 5 years, is the best way we can realize our company purpose and help you maximize your production and thus your profitability. We take seriously having a clear vision of where your problems are now and where they will be in the future. As new hardware and software technologies roll out, we will be there removing the new barriers to your performance then, just as we do now.

1. I-FAAST stands for Intelligent File Access Acceleration Sequencing Technology, a technology designed to take advantage of different performing regions on storage to allow your hottest data to be retrieved in the fastest time.

2. If I can personally brag, I’ve created numerous caching solutions over a period of 40 years.

The Tsunami of Data is Swamping IT

by Jim D’Arezzo, CEO 29. September 2017 09:53

There’s a storm brewing and chances are, it’s going to hit your data center or cloud site.

It’s the tsunami of data that is washing over the IT world and it is just going to get worse. That’s because there is an insatiable demand for data: big data, ERP, CRM, BI, EHR, and of course all of that social media and video that is flooding global organizations like a bursting dam.

I’ll admit it, I’m a dinosaur. I got started in the IT industry in the late 1970’s at IBM. So I can rightly say that I’ve seen a lot in the past 40 years. When I started, it was the heyday of the mainframe era. Data processing was still practically a priesthood back then. It wasn’t for everyone. Bill Gates would not proclaim “Information at your fingertips” for at least another dozen years.

Clearly, we’ve come a long way in four decades. The three driving factors – exponentially increased compute power, nearly unlimited storage, and the internet have delivered computing nirvana. Or so it would seem. But with abundance comes challenges. Frankly, we are now awash in data. The tsunami of available information is swamping IT environments worldwide. And even with huge advances in the three driving factors (compute, storage and the internet) IT is experiencing performance bottlenecks on an increasing basis. Recently, we conducted a survey of 1400 IT professionals and fully 27% said they are experiencing performance problems that are causing user complaints and slowdowns.

As usual, our industry is innovating to keep up. Cloud based computing that takes advantage of huge data centers as well as innovation in storage, compute power and connectivity has kept up with much of the demand. However, most of these improvements focus on hardware – all flash storage arrays; 64-core servers; hyper-convergence. But there’s one other performance innovation that is often overlooked: Software.

Software innovation that takes advantage of existing and new hardware capabilities can significantly increase performance without the cost of additional hardware. Even with an all flash storage back-end, software like ours can significantly increase performance and extend the life of the hardware. The cost-benefit can be tremendous. Imagine getting a 50% boost in performance (or even 2-3X) without buying a single additional piece of hardware. CEOs and CFOs love that kind of benefit.  I know, because that is what we hear from our customers every day.

So, before you get swamped by the tsunami of data that’s lapping at your data center, consider a software solution to the problem. It can help you stay afloat without having to buy a new yacht!

Microsoft SQL Team Puts V-locity to the Test

by Brian Morin 15. September 2017 09:12

In a testament to Condusiv's longstanding 20+ year relationship with Microsoft® as a Gold Partner and provider of technologies to Microsoft over the years, Condusiv® became the first software vendor awarded the stringent certification of MS-SQL Server I/O Reliability joining a very short list containing the likes of Dell® / EMC®, IBM® and HPE®.

Microsoft developed the SQL Server I/O Reliability Program to ensure the reliability, integrity, and availability of vendor products with SQL Server. The program includes a set of requirements that, when complied with and approved by a Microsoft committee of engineers, ensure the product is fully reliable and highly available for SQL Server systems. The certification applies to SQL Server running on Windows Server 2008R2 and later (the most current 2016 release included).

V-locity® Certified for SQL I/O Reliability and Demonstrates Significant SQL Performance Gains

The program itself does not require performance characteristics of products, but it does require I/O testing to exhibit the reliability and integrity of the product. To that end, the full report links to a summary of before/after performance results from a HammerDB test (the preferred load test to measure MS-SQL performance) on Azure to demonstrate the gains of using V-locity I/O reduction software for SQL Server 2016 on Azure’s Windows Server 2016 Data Center Edition. While transactions per minute increased 28.5% and new orders per minute increased by 28.7%, gains were considered modest by Condusiv’s standards since only a limited amount memory was available to be leveraged by V-locity’s patented DRAM caching engine. The typical V-locity customer sees 50% or better performance improvement to SQL applications. The Azure test system configured by Microsoft did not boost available memory to showcase the full power of what V-locity can do with as little of 2-4GB of memory.

Undelete Can Do That Too?

by Gary Quan 30. August 2017 04:46

You may have already heard countless customers tout the file recovery features of Condusiv’s Undelete® and how IT Pros use it as a recycle bin on file servers for real-time protection, so they don’t have to dig through backups to recover deleted or overwritten files. Although this is Undelete’s primary function, Undelete provides more than just this. 

What most people do not know is that Undelete also provides features to keep your data secure and visibility into who deletes files from file servers.

When a file is deleted, many assume that file data is now safe from being seen by others. Not so fast. When data gets deleted on a Windows volume, the data does not get removed. The space where that file data was residing is just marked as available for use, but the original file data is still there and will remain there until that space is overwritten by some other file data. That may or may not happen for quite a while. This means, that ‘deleted’ file data could still be potentially read. 

So, what do you do if you really want your file data gone when you delete it?  Undelete has the answer with two features. The first feature is “SecureDelete.”  When a file is deleted, SecureDelete will first over-write the file to help ensure it is unrecoverable. In fact, this is done by overwriting it with a specific bit pattern specified for this purpose by the U.S. National Security Agency (NSA) for the Department of Defense (DOD).  The second feature is “Wipe Free Space”, which will overwrite any free space on a selected volume, using the same specific bit patterns as SecureDelete to clear out any previously written data in that free space.

Now, with these two features, when you delete a file, you know it is now virtually impossible to read/recover any of that data from that volume.

Along with file security, there are customers using Undelete as another precautionary security: check how many files are being deleted from file shares and by whom. If they ever detect an abnormal, substantially high number of files being deleted, that raises a flag for them to investigate further.

Although Undelete is usually purchased to recover files, others use it to securely delete files and track back any deleted files to the person who did it.

MEDITECH Hospital Speeds EHR & MS-SQL with V-locity® I/O Reduction Software

by Brian Morin 28. August 2017 10:06

Community Medical Center (CMC) had one initial requirement – find a FAL remediation solution for their MEDITECH electronic health record (EHR) application to maintain 24/7 availability and avoid downtime. What surprised them the most was the extent of the performance boost from using V-locity I/O reduction software.

“Our doctors and clinicians were losing too much time on basic tasks like waiting on medical images to load, or scanning images, or even just navigating from screen to screen within the application. The easy answer is to buy new server and storage hardware; however, that’s also a very expensive answer. When you’re a small hospital, you need to squeeze every last drop of performance out of your existing infrastructure. Since we don’t have the budget luxury of doing hardware refreshes every three years, we need to get at least five years or more from our storage backend,” said Joe Buckminster, IT Director, Community Medical Center.

Buckminster continued, “We initially purchased V-locity I/O reduction software to meet an availability requirement, but what surprised us the most was how much value it to added to our aging storage infrastructure by offloading a significant amount of I/O traffic. Not only did we get an immediate performance boost for MEDITECH, but we soon realized that we needed to try V-locity on our other Tier-1 applications like NextGen, MS-SQL, MS Exchange, Citrix XenApp, and others.”

Joe identified 35 key virtual servers that ran an assortment of different applications, like NextGen EHR (supported by a MS-SQL database), MS Exchange, Citrix XenApp, GE Centricity Perinatal, and others. In aggregate, V-locity offloaded 43% of all read traffic from storage and 29% of write traffic. With well over half a billion I/Os eliminated from going to storage, the median latency savings meant an aggregate of 157 days of cumulative storage I/O time saved across all the servers over a three-month period. When examining the last 24 hours from CMC’s single heaviest workload on a MS-SQL server, V-locity offloaded 48,272,115 I/O operations from storage (48% of read traffic / 47% of write traffic) – a savings of seven hours in storage I/O time

“There’s no way we would have achieved a 5-year lifecycle on our storage system without V-locity offloading so much I/O traffic from that subsystem. We had no idea how many I/O operations from virtual server to storage were essentially wasted activity due to Windows write inefficiencies chewing up IOPS or hot data that is more effectively served from available DRAM,” said Buckminster.
