There are three major areas server performance is most heavily
felt: I/O latency,
storage space efficiency and energy consumption. Most problems IT staff has in delivering
services to users begin in one of these areas. When server + time + traffic = slowdown,
attempting to handle this with direct, labor-intensive operations that include downtime
only raises operating costs and lowers net performance to users.
Rapidly increasing need for more and bigger storage is only partly due to the increase
data volume being processed. Unutilized disk space that cannot be written to—bloated
space—can waste up to 30% or more of a disk’s potential storage.
The most common
response is to add more disks, more servers and deploy more load balancing solutions.
All of this represents expenditures that are hard to anticipate and cut into funding
for business initiatives designed to make the company more competitive.
This would be considered "the cost of doing business" if there wasn’t a solution
that would reduce these operating costs. But there is a solution and it’s a good

How do I ensure server storage performance and efficiency?
Server performance problems begin on servers at the NTFS file system layer when
files are not written to disk contiguously and not consolidated or otherwise optimized
for efficient use. Writing and then reading these files involve many additional
Because this inefficiency wastes system resources at its most basic production level,
the file, and because of the sheer scale of read/write operations on even a small
corporate server, I/O bottlenecks build up fast and create slows on all Windows
servers including SAN-attached servers and SAN environments. Hundreds, even thousands
of users may touch server storage simultaneously. Even the smallest inefficiencies
V-locity® I/O optimization software
operates invisibly and automatically at the top of the technology stack right next
to the O/S. It ensures files are written contiguously and thereby read contiguously.
It operates with zero resource conflicts, and also makes free space contiguous on
the fly and recaptures bloated disk space from dynamically set disks and thin disks.
V-locity boosts application performance
by 50% or more by (1) maximizing the efficiency of every single I/O from write requests
that leave the server and (2) caching the most active data from read requests using
available server memory.
Read I/O Optimization – Much of the I/O traffic moving through
the infrastructure shares similar data, yet every byte of that data travels the
entire distance from server to storage and back for every I/O request, even when
it is frequently accessed data. IntelliMemory™ technology addresses
this read request inefficiency by caching the most active data in the server’s available
memory. Should an application require more memory, V-locity serves memory back to
the application to ensure there is never a case of memory starvation or resource
contention. Condusiv Technologies’ self-learning caching algorithms have set the
gold standard for the industry as they are OEM’d by eight of the top ten largest
PC manufacturers in the world.
Write I/O Optimization – V-locity’s IntelliWrite technology optimizes
I/O write operations, eliminating the performance penalties associated with the
Windows OS, splitting files into pieces and writing each piece to a different logical
location within the SAN or NAS. V-locity is aware of space allocation and aggregates
writes to behave sequentially—requiring less I/O for every file written. Subsequent
reads also benefit, since only minimum I/O is required to fulfill the request. As
a result, only productive I/O requests are processed across the entire infrastructure,
enabling more data to be processed in the same amount of time.
V-locity VM™ and V-locity Server™ have been heavily
tested both in labs and in real world environments on every type of work situation
routinely encountered. V-locity consistently demonstrates that optimizing data at
the initial write improves server performance and efficiency throughout the system.
But the benefits go much further. Without V-locity, the typical solution is to either
add more hardware or begin a lengthy troubleshooting process for only marginal performance
gains. With V-locity, you get unprecedented performance gains from software—overnight—no
