Four Reasons to Migrate from Diskeeper Server to V-locity Server

by Robert Woolery 30. July 2013 08:19

Still on Diskeeper Server? Here’s four reasons to consider migrating to V-locity Server: 

1. High performance. Whereas Diskeeper® Server, highlighted by IntelliWrite® technology, keeps Windows servers running like new, V-locity® Server goes a step beyond split I/O elimination with the inclusion of a server-side caching engine (IntelliMemory) for performance boosts of 50% or more. With frequently-accessed data dynamically cached within available server resources, hot data no longer trudges the full distance from server to storage and back, consuming unnecessary bandwidth.

With IntelliWrite preventing split I/Os on write requests, and IntelliMemory caching active data on reads, this holistic approach to I/O optimization accelerates the entire IT infrastructure since unnecessary I/O traffic is now eliminated before it is pushed through server, network and storage. 
 

2. Network storage. Whereas Diskeeper Server is ideal for local server storage or direct-attached storage (DAS), V-locity Server is designed for network storage (SAN/NAS) since all I/O optimization occurs at the Windows OS layer, leaving the storage device untouched. With IntelliWrite, V-locity Server proactively eliminates split I/Os as close to the application as possible, and by caching active data within available server memory, IntelliMemory eliminates even more unnecessary I/O—preventing I/O traffic from traveling the full distance to storage and back. Since the storage subsystem is now processing considerably less I/O, bottlenecks are eliminated and more bandwidth is available. 

3. Solid-state storage. Already running solid-state in your storage arrays or server PCI-E? V-locity sits at the top of the technology stack at the Windows OS layer so the entire infrastructure—regardless of vendor—reaps the benefit of I/O optimization downstream. V-locity is proactive—meaning it prevents the surplus of unnecessary I/O from ever being created in the first place. This way, your SSD or HDD media isn’t dealing with the I/O mess after it has already wreaked havoc on your environment.

4. Benefit analysis. Unlike Diskeeper, V-locity comes with an embedded performance benchmark that allows users to see the before/after benefit of V-locity in their real-world environment and share the outcome with stakeholders prior to any kind of purchase commitment. This single-page report provides metrics like workload comparison, I/Os per second, latency, and more. 

For high-performance in environments that leverage advanced storage technologies, V-locity Server is the best bet to maximize your existing hardware investment and eliminate performance bottlenecks overnight.

A Blog About Bloggers Who Blog About Us

On contemplating the impact of his calculating engine, the world’s first computer, Charles Babbage wrote “In turning from the smaller instruments in frequent use to the larger and more important machines, the economy arising from the increase of velocity becomes more striking.” He said that in 1832.

I mention this because the idea holds true today—the bigness of everything, the immediacy of everything, the pace of everything—the greater the increase from one state to another, the more striking the difference. And that’s exactly why—when we put V-locity 4 trialware into the hands of virtualization wizards to test in their lairs—we want them to really, really put it through the wringer. The heavier the workload, the greater the application demand, the more striking the results.

Recently two virtualization pros got their hands on the V-locity 4 30-day trial, set up rigorous testing, and blogged the entire experience:
