“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.”
“Undelete has worked very well for us. We had been discovering that data was being deleted months prior before we realized it was gone. The backup tapes write over each week and also each quarter so we lost the data. Each morning I review and cross reference our backup with the Undelete data. If I find a large amount of data is added to Undelete, I do a query. A few times I found that information files were inappropriately deleted and we were able to save the files.”
“Diskeeper’s automatic defrag was the biggest selling point for us. Windows machine performance degrades over time and although scheduling a defrag with the built-in tool is an option, we found that the performance was not as good, was of higher impact to the end user and has no central management. The greatest ROI has been IT time savings. This is seen in a reduction of time it takes to push patches and applications. High fragmentation levels cause plenty of issues, not just headaches to the end user. If the hard drive is defragged appropriately then installations of patches go faster."
“Prior to installing Diskeeper we had problems to get and keep the disks defragmented, especially the larger volumes. The performance of those volumes was poor. Diskeeper with IntelliWrite took care of those problems thus greatly improving the disk performance especially the volumes on our HP EVA SAN 4000.”
“I wouldn't have a client machine or a Windows based server without Diskeeper on it. Period! I manage the departmental & enterprise COTS apps. Since first installing Diskeeper I have seen blinding speed and far less hang-ups with Windows - a tremendous improvement. The Trialware expired and within three days my PC was grinding to a halt and hanging on a regular basis; the Windows defrag product made little improvement and took a long time to run. After Diskeeper was registered properly it found over 13,000 fragments and brought my dragging PC back to full brilliancy!"
“Mainly we got licenses for large or multi-terabyte servers, because the built-in defrag doesn’t handle that size well. I always suggest Diskeeper for servers with large terabyte server storage. We are running 40 licenses department wide. We run mostly Windows 2003 32 bit, with 10% on 64 bit, some clustered."
“We use Diskeeper on Windows servers: 3 Diskeeper EnterpriseServers, 45 Servers and the Administrator. We found that, in particular, Diskeeper helps Lotus Notes, which I use heavily, and the Oracle and SQL servers very much. I have worked for other companies that used Diskeeper on Notes servers, so I brought it in here. Once people saw that it made a noticeable difference Diskeeper was run on the other servers."
"We are a large school with nearly one terabyte of data accessed daily, and one-third of that is revised or newly-created. As a network admin, access times and increased throughput are critical to my day-to-day. When my users say, ‘the network seems to be working better,’ I know V-locity is really doing the job.”
“We are running Undelete with VMware ESX and it is working wonderfully. We are very satisfied with the software.”
“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 use HP ProLiant Servers with multiple arrays. I am using traditional ESX with vSphere and an Equallogic iSCSI SAN as well as one Iomega NAS Device. Diskeeper is running on MS SQL Server x64 and Exchange Server as well."
“We keep all servers on a 5-year evergreen cycle and found Diskeeper was able to help us attain that goal by keeping our servers from becoming fragmented and bogging down, overall giving us a much healthier server for a longer period of time and with better ROI. We are running Windows 2008 servers, three SQL 2005 servers and have a blade server connected by fiber to a SAN. We also run SharePoint 2007 with Diskeeper.”
"Our network serves 80 employees with external and internal access to resources, so not too heavy of a load. My primary concern is for the virtualized Exchange server, and V-locity works really well."
"We have seen performance improvements of 522% on our SAP Crystal Server, 190% on the MIS student enrollment application, and an 85% improvement on our Exchange Server."
“I am glad to give references for Diskeeper. We have been using Diskeeper Server for years. I used to receive frequent alerts on server drive fragmentation. After installing your Diskeeper, I have yet to see an alert and have noticed no impact on overall system performance. We are running a few Oracle 9i databases at our site. We have 5 Cybernetics DAS RAID 5 arrays, 1 Lefthand Network iSCSI SAN, a Dell EMC / AX100i iSCSI SAN, and an EMC CX-310 fibrechannel SAN at our site. We also have a Dot Hill fibrechannel SAN for email archiving. We have multiple Lotus Notes production and failover servers and use VMware ESX on 4 host servers running this software."
