ESX and ESXi virtualize every resource with the lowest possible overhead A purpose built scheduler and use of hardware assist technologies for optimizing CPU access Transparent page sharing/ballooning for the most effective usage of memory and hardware memory management assists for the lowest overhead With vSphere ( in ESX 4.0), we introduce several new optimizations that supplement existing mechanisms for the highest output ESX scales now to support 64 cores and 512GB of physical RAM (double our previous limits)– so you can virtualize very large scaled up servers and run them with the most efficiency Virtual machines themselves can now scale to be very large – upto 8 way vSMP and 255 GB of RAM (up from 4 way and 64GB) We introduce numerous storage and network optimizations that allow us to process i/o faster and with even lower CPU overhead We also now introduce VMDirect technology that allows a VM direct access to underlying devices – for the workloads that need constant access to the underlying hardware, this enables low CPU overhead by allowing the VM direct access to the device. Note: The numbers that follow are typically not the result of any one thing we did, we basically worked on optimizations throughout the stack for VMware vSphere 4.0. For those not familiar with or interested in performance, this slide can be covered at just a summary level (extensive optimizations in every component of the stack contribute to increased ability to run the most intense and critical applications in vSphere)
