2 Windows Server 2008 R2 Service Pack 1 Dynamic Memory

3 Memory Techniques

4 Memory Overcommit Overloaded, confusing term Means: To allocate more memory than physically present Memory Techniques Page Sharing Second Level Paging Dynamic Memory Balancing (a.k.a. ballooning)

5 Transparent Page Sharing Efficacy Legacy OSes don t fully utilize memory Windows & Linux SuperFetch Uses Free memory to intelligently cache system ASLR Designed to protect system from malware by randomizing where DLLs and EXEs are located Bottom Line: Page Sharing losing its efficacy

6 Second Level Paging Issue: Swapping Guest Kernel Resources the guest operating system will never page out its kernel pages since those pages are critical to ensure guest kernel performance. The hypervisor, however, cannot identify those guest kernel pages, so it may swap them out. In addition, the guest operating system reclaims the clean buffer pages by dropping them. Again, since the hypervisor cannot identify the clean guest buffer pages, it will unnecessarily swap them out to the hypervisor swap device in order to reclaim the mapped host physical memory. -Understanding Memory Resource Management in VMware ESX Server p. 9-10;

7 Solution Dynamic Memory

8 Dynamic Memory Benefits Enables higher consolidation ratios per host by addressing the greatest limiting factor to consolidation: Memory A Production feature. Overview Memory is pooled and dynamically and securely distributed across VMs Memory is dynamically added/removed based VM usage with no service interruption Guest enlightened: guests & Hyper-V work TOGETHER
