In spite of the fact that performance of storage systems constantly grows, rates of this growth all the same lag behind growth rates of computing power of servers.
It leads to the fact that DWH which is not in time to process input-output requests in case of peak loads becomes a bottleneck.
In IT community this problem received the name I/O gap.
For similar situations the EMC company suggests to use the solution VFCache allowing to cache data even before sending them on DWH.
VFCache represents the specialized payment set in the server. The software set on the server uses the VFCache card in quality a cache memory for the most often used data, reducing time of access to storage and unloading with an array data storage on processing of input-output operations.
As a result, load of a cache memory of DWH and of SAN decreases that allows to lower delays of request processing and to increase performance of all infrastructure in general, to provide data protection of crucial applications.
