Storage Performance

The task of maintaining peak storage performance is critical for the modern storage administrator. More and more mission-critical applications rely on the shared storage infrastructure for real-time activities. Condusiv Technologies Storage Performance Solutions The fact is, these new storage technologies have absolutely improved storage performance, flexibility and manageability, but they have not solved the issues generated at the file system level, such as the tidal wave of unnecessary I/O caused by the Windows OS splitting files apart upon write.

This surplus of unnecessary I/O is a phenomenon that affects storage space, causing it to be used inefficiently thereby reducing storage capacity and performance. Excessive I/O causes bottlenecks, which result in a significant increase in latency, application freezes, system hangs, long disk queue lengths, and more problems.

How do I increase my storage performance?

As storage solutions and infrastructures have evolved, so have solutions to address performance. "Prevention is better than the cure" is a popular and very IT applicable maxim. That philosophy, applied to preventing unnecessary read and write I/O with V-locity's IntelliWrite® and IntelliMemory® I/O optimization technology, is the ultimate solution to maximizing performance of modern storage solutions.

V-locity® uniquely addresses the unnecessary I/O patterns of reads and writes by aggregating data on writes to perform sequentially while caching reads on available server memory without contention to the application. As a result, 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.

When only productive I/O traffic is processed through the server, network and storage, I/Os per second are accelerated, latency is greatly reduced, and more work can be performed in the same amount of time. This greatly improves the efficiency of all VMware ESX/ESXi and Microsoft Hyper-V virtual platforms and physical servers for increased bandwidth.

V-locity I/O optimization is tailored for virtual environments that leverage a SAN or NAS as it proactively provides I/O benefit—improving storage performance and benefiting advanced storage features like snapshots, replication, data deduplication and thin provisioning. Since V-locity optimizes I/O at the server level, it is complementary to all SAN and NAS storage systems and media types (e.g., HDD or SSD).
