PVS7.6 Write Cache mode "cache to ram and overflow to hard disk" Environment RAM size configuration recommendations

Let's look at the new write cache technology cache in RAM overflow to disk RAM recommended configuration:

1. For VDI workloads, even a small amount of memory settings can significantly improve performance. We recommend configuring a cache of at least 256MB for Windows 7 virtual machines, which requires greater than or equal to 256MB;
   

2. For a 32bits Windows7, configure 256MB of cache memory;

3. For Windows 64bits virtual machines generally need to allocate the amount of 3–4GB memory, we recommend allocating 512MB to write cache;

4. For Windows7 64bits virtual machines with more than 4GB of memory, it is recommended to allocate more than 512MB of memory to the write cache memory area, specifically how much you look at it;

5. For XenApp types of virtual machines, it is recommended to allocate at least 2GB of space for the write cache memory area; It is believed that memory is not too large on the current server, so in order to improve performance if possible allocate more than 2GB of memory space. For example, your XenApp allocates 16GB of memory space and recommends allocating at least 4GB of space to the write cache memory area of PVS. Of course, you can test between different values to see which is best;
