Diskeeper is FDCC Compliant

by Michael 21. July 2010 06:08
The Federal Desktop Core Configuration (FDCC) is a security configuration mandated by the Office of Management and Budget (OMB) to standardize the configuration of desktop computers used by U.S. Government agencies. The Defragment software from Diskeeper has been tested to verify compliance with the FDCC under Windows XP and Windows Vista, using a SCAP validated tool with FDCC Scanner capability.
  • Diskeeper 2010 is fully functional and operates correctly as intended on systems using the FDCC under Windows XP and Windows Vista.
  • The standard installation, operation, maintenance, update of Diskeeper 2010 does not alter the configuration settings from the approved FDCC configuration. Diskeeper uses the Windows Installer Service for installation to the default "program files" directory and is able to silently install and uninstall.
  • The Diskeeper 2010 performed correctly on a standard user level account in all functional areas on both operating systems.

You can contact your Public Sector Account Representative at Diskeeper Corporation with any questions about Diskeeper 2010 FDCC compliance.

Just Released: V-locity 2.0!

by Colleen Toumayan 20. July 2010 06:12
BURBANK, CA -- 07/20/10 -- Diskeeper Corporation has officially shipped V-locity™ 2.0, a new virtual platform disk optimizer designed to deliver invisible background optimization of all Windows® Guest operating systems running on the VMware ESX and Microsoft Hyper-V platforms. New to V-locity 2.0, is the addition of the breakthrough IntelliWrite™ fragmentation prevention technology originally introduced with Diskeeper 2010. Utilizing IntelliWrite technology, V-locity writes files to the disk to prevent up to 85 percent of fragmentation from occurring before it even happens.

Already a VMware and Microsoft partner for its Diskeeper® performance software, V-locity was made to create a virtual-specific product that not only performs defragmentation functions, but also synchronizes the complex and ongoing activity between host and multiple guest operating systems in a virtualized environment.

As virtualization platforms begin to age, fragmentation of files in Windows host and guest operating systems generates more disk I/O than should be necessary. Fragmentation creates more overhead on the OS and file system. While CPU, Network, and memory resources may allow for greater VM density, the disk subsystem can become a virtualization "high" hurdle.

"Fragmentation clogged disk subsystems can lead to an inability to run more VMs on given hardware infrastructure, and lead to disk performance bottlenecks for VMs that share a common storage subsystem," notes Diskeeper Product Manager, Michael Materie. "V-locity is designed to alleviate the 'virtual' disk bottleneck for VMs and provide a faster and more efficient computing platform for new consolidation and provisioning initiatives, without having to add more hardware."

"First of all, when building out my environment I make sure to have fast hard drives, controllers, etc., in order to make sure not to suffer bottlenecks. In addition, I am very careful about not over-committing resources. However, I was shocked to see, after deploying V-locity, how much performance increased on the servers I had hosting disk-intensive operations. This includes our database server, our Exchange server, and to a certain extent, two terminal servers," stated Bill Philpot Manager of Information Technology at Mesa Industries, Inc.

Diskeeper Corporation's proprietary technology, IntelliWrite writes files in a non-fragmented condition. Copy on write solutions (e.g. as used by Snapshots) take action on changes to data at a block level. Moving data, as is done in a defragmentation job to consolidate file fragments in a logical file system, can trigger copy on write solutions to take extra actions such as using more storage capacity, unnecessarily. Writing a file contiguously eliminates the need to defragment it after it has been created.

InvisiTasking® technology, another Diskeeper Corporation proprietary technology, is specifically engineered to allow "background" applications to operate with zero impact/overhead on a system. With V-locity 2, the InvisiTasking technology has been "enlightened" to operate across a virtual platform. Even as more VMs are added to a host platform or dynamically migrated to new hosts (e.g. vMotion, Live Migration), the enlightened InvisiTasking will continue to dynamically adjust to changing environments, providing V-locity 2.0 users with "Set It and Forget It" ® optimization of their virtual disk platforms.

V-locity also frees up vital storage resources by eliminating virtual disk "bloat." This is the wasted disk space that takes place when virtual disks are set to dynamically grow but don't then shrink when users or applications remove data. V-locity actually compacts the virtual disk, thereby preventing waste and allowing IT Managers to better allocate their virtual storage resources.

V-locity has four unique solution sets:

  • InvisiTasking - coordinates resource usage to ensure defrag is 100% invisible

  • IntelliWrite - prevent fragmentation and offer 100% compatibility in all environments

  • Virtual Disk Intelligence - automatically detects and configures based on virtual disk type

  • Virtual Disk Compaction - shrinks/compacts virtual disks that are set to grow-as-needed

V-locity consists of three components:

  • V-locity Host installed in the VMware ESX Host or Windows Server 2008/R2 operating system running Hyper-V.

  • V-locity Guest installed in all Windows virtual machines.

  • For VMware ESX platforms: V-locity includes a small application that allows you to remotely connect from your Windows desktop to the V-locity Host component on an ESX system.

Note: On Windows platforms, each component will optimize its respective OS; performing defragmentation of files and consolidation of free space. This minimizes unnecessary I/O passed from the OS to the disk subsystem and aligns data on the drives for optimal access.

Keeping your SSD running brilliant

by Michael 19. July 2010 10:00

I came across a cool "how to" video today. It covers steps to keep a high-end rig running three SSDs in top form. The http://www.sirjamesd.com/ also happens to use HyperFast as part of his toolkit.

You can check it out here: http://www.30monitor.com/keeping-your-ssd-running-brilliant/

On another note, while the author is running Diskeeper Pro Premier, if you only have SSDs in your PC, save yourself some money and just get Diskeeper Home edition with HyperFast. The features in DK Professional and Pro Premier (I-FAAST and TVE) are only useful for HDD.

I'll cover more on I-FAAST and talk about TRIM and defrag in more detail in a follow up post. You can also see this post for some test data from a joint Microsoft/Diskeeper Corporation seminar.

Defragged Files = Greater DR success

by Colleen Toumayan 14. July 2010 06:15

Here's a cool succes about something many IT pro's wouldn't normally associate with defrag:

 

When we began to invest in Diskeeper we had 8 servers and over 100+ clients that ran for years and would run for many more years. Every 11 weeks we start a new quarter and cycled on average 400 users across all of them each quarter. So you can image the amount of data our students move across these machines. Not to mention the amount of data that is moved across our servers with 600+ users. 

Diskeeper drastically improved our disk performance and kept it constant with the automatic defragmentation during idle time. Diskeeper not only helped with maintaining the disk performance, but also made it possible for quick disaster recovery.

We had an old file server that crashed and file backups were being neglected, so we had to run file recovery on the RAID 5 array. Without Diskeeper automatically defragging the drive and keeping all the pieces of the files together, we would have lost 50% of the data; instead we were able to recover 95% of the 300 Gb of information.

New WIndows IT Pro white paper on SAN defrag

by Michael 9. July 2010 09:00

Windows IT Pro analyst David Chernicoff just published a new white paper that covers the issues file fragmentation causes on SAN storage. It's titled "Maximize the Performance of your Windows SAN Infrastructure" and you can download it from their website (here). If you don't already have an account with them, you'll need to fill out a quick profile.
