Product Review: Diskeeper V-Locity 3
I'm a firm believer in the necessity of disk defragmentation. While some people maintain that solutions providing "always on" defragmentation are unnecessary in modern OSs with large amounts of RAM and intelligent caching of commonly accessed files, I've found that these programs turn a fast computer into one that's snappy. Although this isn't a night-and-day difference, it's an improvement that some users are prepared to pay for. Despite this, I've had a long-standing love-hate relationship with Diskeeper software. Only with the release of Diskeeper 2011 and its inclusion of the Efficient Mode have I been truly satisfied that the program isn't constantly chugging away at my disks aiming to maintain a perfectly defragmented state at all times, which is indeed unnecessary.
Many servers now utilize virtualization of one kind or another. File caching isn't optimized to work with virtualized workloads and it's unlikely that there's ever going to be enough RAM, so raw disk performance comes back into the spotlight. Based on the same defragmentation engines as Diskeeper 2011, V-locity runs on Hyper-V host servers, providing local disk and SAN defragmentation. During the defrag process, it monitors agents deployed on the guest virtual machines (VMs) to ensure there's no contention for disk resources. V-locity requires a separate Windows VM (or physical device) to run the host software in VMware virtual infrastructures.
V-locity supports Windows XP SP2 or later and Windows Server 2003 or later guest OSs on Hyper-V and VMware ESX/ESXi 4.0 or later hosts. VM guests are also supported in Citrix XenServer.
Installing V-locityMy test system consisted of Hyper-V running on Windows Server 2008 R2 with a collection of Windows Server guest VMs. I found that installing the host software is straightforward and includes a warning that Windows Firewall settings might need to be modified if Diskeeper Administrator will be used to manage V-locity.

With all the noise about how last year's floods in Thailand have wrecked the hard drive industry, and Intel's latest efforts on ultrabooks (laptops which are obliged, by its requirements, to have some sort of solid-state disk, aka SSD, storage) it's
