I/O optimization software, which prevents the surplus of unnecessary read and writes I/O from being created, dramatically decreases backup times. While different backup tools will be differently affected by excessive I/O, the majority of V-locity customers are surprised by the huge improvement in backup speeds and completion rates.
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 write to behave sequentially—requiring less I/O for every file written. Subsequent reads also benefit, since the 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.
“I’ve seen as much as an 88% improved backup time on one server.”
