SQL Server High Performance and Product Selection

Hi Forum,

    Can anyone confirm the following understanding:-

    - Both parallel process in one instance or multiple instances (MPP), it is not In-Memory computing yet.

    - Parallel in one instance will be limited by the memory the single instance can have, e.g. there could be limitation on the memory allowed in VM.

    - What is the memory limit for PDW II?

    Thanks.

Regards,
