“I am running V-locity on my virtual guests with a 32% improvement for the read write access and the server with a 29% better read/write access. Recently a field engineer came in to look at and ‘fix’ my Active Directory domain as according to those in the know, I had bad objects that prevented things from working properly. Ten minutes after the systems engineer placed a tool on a server he stated the system is in good shape and in fact, it’s now in better shape since he fixed a couple of things that were above my knowledge level. He said this system is one of the cleanest domains he has worked on. It’s running with Exchange Server 2010. This is a very good benefit!”
“Diskeeper has our fragmentation in check across the board and I couldn't be happier with it. Without effective, real time fragmentation management you simply cannot get results that meet your expectations. What I like best about Diskeeper is that it is much more efficient than the Windows built-in defrag, and that I can block out time in the Automatic defrag so that it doesn't get in the way during business hours; we have many servers on an Dell EqualLogic iSCSI SAN. Keeping fragmentation under control is especially important with our SAN configuration, and I don't have to think about it anymore.”
“We have been running Diskeeper for years, and when we began the switch to virtualization using Hyper-V, V-locity was suggested to help improve performance of the VMs. V-locity has proven to be a valuable tool in our virtual environment. It is also a “Set It and Forget It” type of software. The IntelliWrite technology is a huge factor in the overall great disk performance we are seeing on our virtual platforms by preventing most fragmentation from ever occurring. Also, InvisiTasking helps ensure that the defrag process doesn't affect other VMs. We are very pleased with the steady performance state we are seeing from our VMs due to our implementation of V-locity.”
“We had several servers experiencing a variety of performance problems. Knowing that a severely fragmented hard drive can lead to performance problems, we had to free up drive space. We employed Diskeeper to handle the severely fragmented drive. Now, our servers are all running quite satisfactorily with drastically improved performance. Diskeeper is certainly a critical element. Diskeeper continually maintains a defragmented drive thereby maximizing read/write times, thus server performance is maximized. Quite frankly, we looked at replacing our main file server at the cost of several thousands of dollars, but we have been able to table that expense due to the resolved issues.”
“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.”
“I love using Diskeeper on our Backup Exec Server; this is the real success story. It can have 10 jobs that write to 50 GB files all at the same time. This fragments the heck out of our 13 TB drive tower. The Windows defrag wouldn’t keep up or even finish. I was always reaching 99% fragmentation on this drive, causing my backups to go all the way from Friday to Wednesday of the following week. When I contacted the backup solution company about the severe fragmentation they suggested only running one job at a time. This was just unacceptable as the jobs would not complete in the allotted time window."
“We have Diskeeper Admin Console setup on a Windows 2003 server domain environment. We push out Diskeeper clients from the Diskeeper Admin server to a mix of Windows XP, Server 2008, and Windows 7, 32 and 64 bit computers. When deploying the Diskeeper client and or upgrades to computers we will scan computers to see what they need from the Admin server."
“This system runs the software that routes all our trucks and outbound scheduling. With the Diskeeper Administrator I can see which computers are not performing at their best and the status and health of the hard drive. It also made installation quick and easy with the software push and upgrade ability.”
“We are still happily using and ignoring the Diskeeper product as it silently works in the background, saving us from having to worry about defragging our hard drives using less reliable means. We’re presently using Diskeeper on non-virtual Windows 2000, Windows 7, and XP machines as well as Windows 2008 servers.”
“Our company is better off from using Diskeeper as our servers, computers and gateways see a noticeable difference in file access on the defragged drives. The biggest gains are on systems that do a lot of read/writes and even more if the files are temporary. We have been using Diskeeper for a number of years and just recently moved to a new SQL Server. Boot times are better and virus scans do run faster. The biggest improvement has been the interval between PC ‘cleanings’, when Information Systems go out and clean up the workstations by re-imaging. I simply pay attention to how the systems work before and after defragmentation.”
“As you transfer data to a hard drive it cannot take into account that the recorded data will change or the files may become larger. The hard drive will write and store data in pre-determined quantities and fills space based on the table that keeps track of where and how much data exists. The fragments result because files change, become larger, and the space it resides in remains the same due to data stored at its boundaries. The hard drive maintains a record of how the data is stored so if a file had to be extended and could not be appended, the additional data would be stored in a free space area."
“We run an application that specifically benefits from Diskeeper - a SQL-based large database program that keeps all of its data in one huge file. Diskeeper keeps the drive optimized so efficiently that we’ve noticed a significant decrease in database lockups. Also, our Exchange server gets a big boost from Diskeeper. Our ROI has been in productivity savings. The IT staff does not have to run utility and maintenance programs to keep the servers optimized and running smoothly as when new. This saves us at least twenty IT hours per month. Because of the continuous optimization of the user programs on the servers, our users have experienced a 99.97% uptime over the past 12 months. The prior 12 months was only about 91% uptime due to all the disk-related issues. I was hired about that time and insisted that we install Diskeeper on all the servers. This has definitely paid off.”
“I consider Diskeeper to be a valuable tool and am very pleased with our deployment of it. We have Diskeeper Administrator running on our internal domain and use it to deploy and manage our Diskeeper clients. We have defrag policies set up and use them to keep production running. I personally like the ease of use the Admin Console gives me to manage and deploy new installs on our network. With just a few clicks I can edit defrag policies to fit our production needs as we bring up different workloads and shifts. Before we just used the built-in defrag tool in Windows to defrag servers and PCs. By using Diskeeper and the Admin Console, I can automate all of that and know that it is being done. Each morning I have scheduled reports which run to inform us of the current fragmentation levels and performance indicators. I also have it set up to email when a new upgrade is ready and can see all the machines it is installed on and what version they are running. This makes my task of managing these systems so much easier for me and my co-workers.”
“We use V-locity on our web servers, accessed by many users through our website and by systems in each of our libraries. We have seen over 100% performance gains. This means I don’t have to replace servers, and our patrons gain a huge boost in response time.”
“I thought you may like to know that V-Locity saved me yesterday! I was trying to correct a VMFS storage space issue after I was advised by my VM backup vendor to run sDelete on all the server drives to improve performance. As it turns out, VMware does not recognize this zeroed disk space as ‘free’ but as ‘used’ which filled up my datastores! This resulted in some of servers going into stand by and after a lot of research, there did not seem to be any quick solution."
