One of the most significant potential issues, and probably the most unrecognized, is defragmentation in a SAN storage system
Burbank, CA (Vocus) July 14, 2010
Diskeeper Corporation, innovators in performance and reliability technologies®, today announced a newly released Windows IT Pro whitepaper detailing how disk defragmentation is vital to technologies like SANs.
“One of the most significant potential issues, and probably the most unrecognized, is defragmentation in a SAN storage system,” stated David Chernicoff of Windows IT Pro.
As advanced as it is, SAN technology still suffers from a very basic performance barrier: file fragmentation. Although new disk subsystem technologies do contribute to a better performing system, they do not solve issues generated at the file system level such as file fragmentation.
Chernicoff stated, “The effects of fragmentation in SAN storage often manifest in reduced application performance and inefficient use of storage. Application response time begins to increase, the time necessary to load large files grows longer, and the overall user experience is impacted. Applications themselves, if loaded from the SAN storage, take longer to launch. End-users begin to feel that their computer is slowing down, leading to help desk calls with complaints about network performance or some other imagined problem. The reality, however, is that the fragmentation is simply causing data manipulation times to increase to the point where the delay becomes perceptible to the end-user.”
The paper further shows that defragmenting SANs not only boosts system performance and reliability, but it also prevents companies from investing in unnecessary extra storage.
When performance lags, additional spindles are added to the storage device. This approach addresses the performance problem by spreading the load over a larger number of high-performance drives, but add¬ing hardware to resolve SAN performance problems means that more money is spent masking the performance problem rather than addressing the root cause of the performance hit: fragmentation,” acknowledged David Chernicoff of Windows IT Pro.
