Overview The intensified demand for IT network efficiency and lower operating costs has been driving the phenomenal growth of virtualization in the past decade, with no signs of slowing. At present, many corporations run more virtualized servers than physical servers. While virtualization provides opportunity for [...]
“We are now running Diskeeper 2011 EnterpriseServer on our a DFS server which houses all our corporate documents. This server has about 500GB of files and was heavily fragmented prior to installing Diskeeper. “Users were experiencing latency issues, login delays (roaming profiles) and sometimes apps [...]
Diskeeper (data performance for physical systems) and V-locity (optimization for virtual systems) are designed to deliver performance, reliability, longer life and energy savings. Increased performance and saved energy from our software are relatively easy to empirically test and validate. Longer life is a matter of minimizing wear and [...]
Okay, so you've bought, installed, connected, configured, and then tuned/optimized your new storage virtualization solution, but somehow there are still latencies with apps (e.g. SQL). You've run the Storage Area Network (SAN) vendor utilities that: did not see any contention on the disks in the RAID group(s). [...]
Overview: As high performing storage solutions based on block protocols (e.g. iSCSI, FC), SANs excel at optimizing block access. SANs work at a storage layer underneath the operating systems file system; usually NTFS when discussing Microsoft Windows®. That dictates that a SAN is unaware of [...]
One of the most significant features in Windows 2008R2 (for Hyper-V) is Cluster Shared Volumes (CSV) for virtual disks (vhd). This allows NTFS to behave similar to a clustered file system, addressing many limitations found in Hyper-V storage with the original release (Windows 2008). There are three online [...]
When Windows NT 4.0 was released, Diskeeper 2.0 hit the market. NT 4.0 had limitations about the type of data that could be safely moved online. So, a market-first innovation that Diskeeper brought to market with Diskeeper 3.0 was what we called Boot Time Defragmentation. Boot Time Defragmentation addressed these special [...]
On April 10, 2002, Diskeeper enjoyed 15 seconds of TV game-show fame on the TV show Jeopardy with the answer: "Diskeeper is software to do this, reorganize your computer’s files." The contestant won $2,000 by correctly providing the question, "What is defragment?"
The purpose of this blog post is to provide some data about fragmentation on the Mac, that I've not seen researched/published elsewhere. Mac OSX has a defragmenter in the file system itself. Given Mac is open-source, we looked at the code. During a file open the files [...]
Dear CIO, One of the most positive things to come out of the recession is a deeper appreciation of how much an efficient IT impacts corporate competiveness and profitability. And no wonder: envisioning and acting upon business opportunities requires having a powerful and flexible data [...]
