VMware vSphere 4.1 Features Large Capacity Cluster, VM Density
Review: VMware vSphere 4.1's memory compression, storage and network I/O control, along with a cluster limit increase, make the latest virtual machine platform suited for enterprise production use.VMware vSphere 4.1 continues to lead the enterprise virtual machine platform pack. New memory management, storage and network control features enable resource pool creation that improves scale while reducing performance drags. Virtual machine management gains increased in importance in the vSphere 4.1 platform, and data center managers should plan on assigning virtualization experts to ensure that the new features lead to improved host utilization and automated scale-out of VM systems.
During eWEEK Labs tests I learned that vCenter 4.1-the command and control module of VMware's virtual infrastructure world-is now 64-bit only. IT managers should build in extra planning and migration time to move any vCenter 4.0 or older servers to systems that are running a 64-bit OS as part of the move to vSphere 4.1.
