"With V-locity, we have delayed investment in additional hardware. We've virtualized servers that used to run on dedicated storage, and now we're using our resources much more efficiently."
"Diskeeper is rock solid, does what it’s supposed to do, and does not break like 80% of all other software. Window’s built-in defrag could keep the server functional, but it was a manual process. If you are handy with writing scripts you could schedule it but for us it was not worth the time. Diskeeper runs automatically with a thorough, deep defrag process. We run Diskeeper on all of our servers to keep them at optimal performance. I have been using it for 12 years and have not been disappointed in any way. Ease of installation, never had a conflict or issue of any kind. Just like one of the menu choices in Diskeeper, the “Set It and Forget It” scenario really applies.”
“We have been using Diskeeper for a while now, so we now receive few service calls related to fragmented disks; using Diskeeper has helped to keep such calls to a minimum. “Our intention with Diskeeper is to keep disk fragmentation at a reasonable level and Diskeeper does that; this activity reduces the instances of problems with disks that are nearly full or very heavily fragmented. We have approximately 75 Dell Latitude E4200 laptops with SSDs. We distribute Diskeeper with HyperFast to systems by including Diskeeper in the Ghost images we use when we set up a new computer."
“Diskeeper is an excellent product. I have deployed some of the licenses that we have, focusing on servers that did not seem to be performing well. We use an IBM XIV SAN for the virtual hard drives of our VMware virtual machines, and some physical servers also have SAN-attached drives. On the servers that I’ve deployed Diskeeper to we’ve seen noticeable improvement in overall performance. The most impressive thing in my opinion is that Diskeeper does its job without bogging down the server like so many other defraggers tend to do. I like the product; it’s easy to deploy, easy to maintain, and does its job transparently.”
"We knew we had an I/O problem and had reached the IOPS limitation of our backend storage architecture under peak load. However, what we did not consider is how much of our storage performance was being dampened by small, fractured, random I/O characteristics due to Windows write inefficiencies that generate excessively small writes and reads. That was ultimately the root cause problem why our users were timing out from Exchange."
"After months of trouble shooting, we ran the same query with V-locity on all the Cognos VMs. It completed in one third of the time—a huge improvement for our users. We're now rolling out V-locity to the rest of our virtual environment and assessing it for physical servers."
“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 have had very good results from using Diskeeper on our Lotus Notes servers. These servers are absolutely the worst for fragmentation issues including resultant corruption of critical files. (Notes databases and indexes), plus with spam coming in vast quantities and people cleaning/deleting their mail inboxes sets the stage for a lot of fragmentation as well. I definitely recommend Diskeeper because of its real impact on server performance. You make a great product and one that can be installed carefully ’live’ without worry of an outright crash or any application problems.”
“Any lag we used to experience during peak load has disappeared. In addition to performance gains, we no longer have to reboot servers once a week.”
“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.”
“File fragmentation had a significant impact on the backup performance of all servers previously identified. Defragging drives on Server1 (both target and source drives) with Diskeeper helped boost throughput by 67%, the average throughput increased from 7MB/s to 11.7MB/s for 5 concurrent drive backups. The longest runtime for any backup job in that group was 10 hours. Defragging the target drives on Server2 increased throughput by 73%, the average throughput increased from 5.9MB/s to 10.2MB/s for 6 concurrent drive backups. The longest runtime for any backup job in that group was = 11.5hrs. Consequently, all tape protection operations ran properly and according to schedules with no data sets missed.”
“I love the Diskeeper Server product and the fact that you support the 64bit Itanium Operating System is a huge benefit to us. These systems are very critical and the fragmentation prior to using Diskeeper was really hurting performance. The drives were at about 90% fragmentation and with Automatic defrag enabled they stay around 3-5%. That feature alone makes the product worthwhile.”
"With V-locity, our SQL batch imports can run during the night so data is ready for production in the morning. Before V-locity, batch jobs would take so long, we would lose a full day of production and sometimes two."
“V-locity works great. It is easy to install and then it just runs. It keeps my Hyper-V virtual machines from fragmenting and I never have to worry about it. It is true “Set it and Forget it” software."
“Here are some metrics numbers on our environment as reported by the Diskeeper job report. It’s pretty impressive. We run over 900 Windows servers here at UK Healthcare. Around 600 are physical, and 300 are virtual. We run Diskeeper on almost all of these. We use various SAN backbones and an IBM SVC SAN controller. Diskeeper has also been used on SAN connected drives as well. We run dozens of different applications, mostly of a healthcare nature. Our primary clinical application is Allscript’s Sunrise Clinical Manager. We publish that through Citrix and it is run entirely on Windows OS’s, which are all running Diskeeper."
