We are in the process of building out our combined CAS/HT servers. We will have 3 combined CAS/HT servers and each have 2 6GB cores. The servers came with 64GB of memory. The discussion we are having internally is whether or not to reduce that amount of memory from 64 to 32GB. Microsoft states that the recommended max memory for a combined CAS/HT is 2 x number of cores which would put our spec at 24GB. Personally I feel 64GB is too much and could cause performance problems. Also we would need to install Enterprise on these servers which will result in a higher cost. We will also be using a netscaler to load balance the CAS/HT and use SSL offloading.
Can you take a brief second to provide your recommendation to the above situation. It would be much appreciated.
