What is the main purpose of compression in memory management within vSphere 6?

The primary purpose of compression in memory management within vSphere 6 is indeed to enable faster access to memory pages. When memory pages are compressed, they occupy less space, allowing more data to be stored within the same amount of physical RAM. This efficient use of memory leads to improved performance as the hypervisor can access and manage memory pages more quickly.

By compressing memory, vSphere can reduce the amount of data that needs to be transferred between RAM and disk storage, leading to lower latency when accessing frequently used data. Additionally, when memory is compressed, it may facilitate a more efficient use of available memory resources, reducing the need for additional memory allocation and enhancing overall system responsiveness.

In contrast, the other options focus on aspects unrelated to the actual function of memory compression. Data security is a distinct concern that does not directly relate to the mechanics of memory management. While having more physical RAM can improve performance, compression itself does not create additional physical RAM but rather optimizes what is currently available. Network performance is also influenced by many factors, but compression pertains specifically to memory utilization rather than network operations.
